Current as of 27 October 2026, checked against the Gambling Commission’s public register and each operator’s own terms.

A promo code is the smallest part of a sign-up offer. What the offer pays, what it demands in return, and how much of that demand actually reaches the bookmaker’s pocket — that is the comparison. Welcome bonuses in Great Britain have sat under a single rule since 19 January 2026: no wagering requirement above 10x the bonus amount, and no offer that ropes a customer into gambling across two or more product types at once. The rule sets a ceiling; it does not clear the floor. The mechanics still differ from brand to brand, and the cost of clearing the offer still lives in the turnover, the minimum odds and the expiry window.

This page is the read on the cost side. Every figure below is from the operator’s own terms as published on its UK site or app store listing on 16 October 2026, and every licence line is checked against the Gambling Commission’s public register. The maths is worked through the offer a real bettor would actually claim, on the assumption they wager only what the offer requires. None of it is a tip.

How UK promo codes actually work

A promo code in the strict sense is a string a customer types in at registration or in the cashier. Most UK welcome offers in 2026 do not work that way. Coral, Unibet, Betway and Hollywoodbets instead frame their welcome offers as opt-in promotions: the customer ticks a box, deposits a set amount, places a qualifying bet at a set minimum price and gets free bet tokens credited once that first bet settles. The “code” is, in practice, the act of opting in within the right window.

What the code is for is to track which marketing channel brought the customer in, and that tracking is what entitles the customer to the welcome offer. Without the opt-in, a new account receives nothing. This is also why the same brand will run a different headline offer through an affiliate link than it does on its own homepage, and why the headline number alone is a poor guide to what lands.

A promo code, then, is the on-switch for an offer whose substance is set out in three lines of small print: how much to deposit, what to bet, and what comes back. That substance is what the rest of this page works through.

The bones of a betting sign-up offer

Strip the marketing away and every welcome offer in the featured set resolves to the same skeleton. The customer deposits, places a qualifying bet at a minimum odds floor, and receives free bet tokens whose value is a multiple of that first bet. The free bets are then spent on a further set of selections — usually at a minimum price, sometimes with a cap on how many selections can be combined, almost always with a deadline.

Take Coral’s headline offer as the worked example: deposit and bet £20 or more at minimum odds of 2.0 (1/1), receive £40 in free bets credited within seven days, free bets expire seven days after issue, GB customers only, debit card or instant bank transfer funding only. Unibet’s headline reads identically: £20 in, £40 in free bets out, same minimum price, same seven-day expiry, same funding route. The two brands run parallel terms because the structure is what the market has settled on.

Other brands scale the structure differently. Betway credits four £10 tokens for a £10 first bet at minimum odds of 2.0, again with a seven-day expiry and debit card funding only. Sky Bet credits three £10 tokens for a 5p first bet at odds of 1/1 or greater, after a £5 deposit. Hollywoodbets refunds a losing first accumulator as a free bet of up to £30 — a stake-back offer, where the free bet is issued only if the first qualifying bet loses. Spreadex, which holds both a Gambling Commission fixed-odds licence and an FCA spread-betting licence, gives £60 in free bets across fixed odds and spread betting for a £10 fixed-odds qualifying bet, with the qualifying bet to be placed within 28 days of opening the account.

The differences are in scale and shape; the skeleton is the same. Where the costs diverge is below the headline: the minimum price for the qualifying bet, the deadline on the free bets, whether the free bet stake is returned with a win, and which payment routes count. Those are the four numbers that decide what an offer is actually worth.

The four numbers that decide the value

Minimum odds on the qualifying bet

The qualifying bet is the bet that unlocks the offer. Its minimum price is the floor the selection must clear for the bet to count. Coral and Unibet both require minimum odds of 2.0 (1/1). Betway requires the same. Sky Bet requires odds of 1/1 or greater for a 5p bet, which is the lowest meaningful threshold in the market. Spreadex’s free bets are unlocked by a qualifying fixed-odds bet at minimum odds of 1/2. Hollywoodbets’ stake-back offer applies to a losing accumulator with three or more legs at combined odds of 4/1 or greater.

A higher floor on the qualifying bet means the customer is pushed toward selections the bookmaker would rather take — longer prices carry more margin, and a £20 bet at 1/2 is a far cheaper free bet to issue than a £20 bet at 5/1. The headline number stays the same either way.

Minimum odds on the free bet

Free bets almost always carry their own minimum price. QuinnBet’s free bets can be used on any market at odds of 1/2 (1.5) or greater, with a maximum odds of 50/1, and straight accumulators are allowed but Trixies, Patents and Yankees are not. Most other operators set the same 1/2 floor without naming it; Betway’s free bet terms, for example, require the same threshold but quote it differently in the small print.

A 1/2 floor sounds low but matters: at 1/2 the implied probability is 67%, and a free bet at that price is worth close to nothing on average. The maths is in the worked section further down.

Expiry

Free bets expire. Coral’s expire seven days after issue. Unibet’s expire within seven days of issue. Betway’s expire in seven days. Sky Bet’s free bet tokens run on the same seven-day clock. QuinnBet’s are valid for seven days from credit. Hollywoodbets’ stake-back free bet runs on the qualifying bet’s settlement plus seven days. BoyleSports’ acca insurance free bet expires in seven days. Spreadex gives no equivalent figure on its welcome offer because the qualifying bet itself must be placed within 28 days.

A seven-day window is short. It is short enough that the customer who has not picked the selections in advance is pushed toward whatever is live, not whatever they would have chosen with a clear head. The bookmaker benefits twice: a cornered customer tends to take whatever is offered, and a cornered customer’s selections tend to be on heavily-margin markets. The expiry is the offer’s quietest cost.

Stake returned or stake forfeited

A free bet in Great Britain is almost always a stake-not-returned free bet. The £10 free bet token at 5/1 returns £50 in profit if it wins, not £60. The distinction is the difference between a free bet and a risk-free bet, and most operators use the language of the latter while running the mechanics of the former. The arithmetic on this is in the worked section.

A small number of offers return the stake alongside the win. Hollywoodbets’ stake-back offer, for instance, refunds the qualifying stake as a free bet rather than paying the free bet as a headline bonus — but the free bet it issues is still a stake-not-returned token. The pattern holds: the headline is generous, the free bet that follows is the standard one.

The 10x cap and the mixed-product ban

Two rules came into force on 19 January 2026 that govern how welcome offers and ongoing promotions are structured in Great Britain. The first is a hard ceiling on wagering requirements: no more than 10x the bonus value may be required to be turned over before the bonus and any associated winnings become withdrawable. The second is a ban on mixed-product promotions: no offer may compel a customer to gamble on two or more product types — betting, casino, bingo, lottery — as a condition of receiving the bonus.

The 10x cap is the rule that changes what an offer can ask. A £10 bonus used to carry a 50x wagering requirement — £500 of qualifying turnover — under a structure that prized the bonus headline over its realisable value. Under the cap, a £10 bonus can require no more than £100 of turnover. A £50 bonus can require no more than £500. A £100 bonus can require no more than £1,000. The cap is binding where it bites, and it does not bite where the bonus has no wagering requirement at all — Sky Bet’s £30 in three £10 free bets, for example, is a free bet offer with no turnover condition on the bonus itself, only on what the customer chooses to do with the tokens.

What the cap does not settle is whether it applies to free bets with no wagering condition. The Commission’s consultation document left that point open, and the brands in the featured set run their free bet offers without an explicit turnover condition on the tokens. The free bets are still stake-not-returned; the cap does not turn a free bet into cash.

The mixed-product ban is the rule that closes off the “bet on football to unlock free spins” route. BoyleSports, Coral and others used to bundle casino spins or bingo bonuses into a sports welcome offer; the bundle is no longer lawful where it makes casino play a condition of the sports bonus. The bundles still exist as opt-in additions, but the customer is no longer compelled to clear one product type to receive the other. For the cost-conscious bettor, this is the cleaner of the two rules: it stops an offer from quietly doubling the cost of clearing.

The maths on a Coral £40 welcome offer

Coral’s headline offer — bet £20 at minimum odds of 2.0 (1/1), receive £40 in free bets — is the worked example. The numbers are Coral’s own terms; the arithmetic is the page’s.

The free bets come as a bundle whose individual token sizes and expiry windows Coral sets in its own terms. The headline value is £40. The customer has seven days from issue to use the tokens. Each token is a stake-not-returned free bet; the qualifying bet must be placed at minimum odds of 2.0.

The cost of clearing the offer is the cost of finding £40 of value out of £40 of tokens. The value of a stake-not-returned free bet at minimum odds of 2.0 on a market with a typical 5% margin is, on average, £40 × (2.0 − 1) ÷ 2.0 × 0.95 = £19. The free bet is worth £19 in expected profit before any minimum-odds restriction or expiry pressure.

The qualifying bet itself is a separate cost. A £20 bet at minimum odds of 2.0 on a market with a 5% margin has an expected loss of £20 × 0.05 = £1. Net, the offer is worth roughly £18 in expected value, with a wide variance depending on which selections the seven-day clock forces.

The variance is the point. Coral’s headline reads as £40 of free bets; the realised value on average is well under half that, and the seven-day clock is the mechanism that pulls the realised figure toward the average.

The maths on a £50 betting bonus with a 10x turnover

A £50 betting bonus is the kind of headline the mixed-product ban used to be paired with. The 10x cap on wagering means no more than £500 of qualifying turnover to clear. At a £10 stake per bet and a minimum odds floor of 1/2, that is fifty bets.

The cost of those fifty bets depends on the market they are placed on. A football 1X2 market with a 5% margin costs the customer £500 × 0.05 = £25 in expected value across the qualifying turnover. A horse racing market with a 15% margin — a typical overround on a competitive race — costs £500 × 0.15 = £75. The same bonus cleared on two different sports is two different offers.

This is the second-order effect of the 10x cap that does not show in the headline: a cap on turnover is also a cap on the bookmaker’s margin exposure, and operators have responded by steering customers toward higher-margin markets. Coral and Unibet’s minimum odds of 2.0 on the qualifying bet are a softer form of the same steering; the qualifying bet must carry enough margin that the bookmaker does not lose money on the act of issuing the free bet.

What the offer costs in time and attention

A welcome offer’s cost is not only the expected loss in the maths. The seven-day expiry on the free bets is a forcing function. The minimum odds on the qualifying bet is a guide to which market the offer wants the customer on. The debit-card-only funding rule — present at Coral, Unibet, Betway, Hollywoodbets — is a friction point that exists because credit cards have been banned for gambling in Great Britain since 14 April 2020, and the e-wallet that funds a debit card is treated differently from an e-wallet that funds a credit card.

The friction has a value. Coral, for example, lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options, but the welcome offer is qualified only with a debit card or instant bank transfer. A customer who normally funds the account with Revolut Pay will need to change route to claim. The friction is a feature, not a bug: it stops the customer from optimising across multiple welcome offers in quick succession, because the verification that runs at sign-up — name, address and date of birth, with the £150 rolling 30-day vulnerability check since 28 February 2025 — runs only once per operator, and is hard to reset.

Where UK promo codes cannot go

The promotion rules in force since 19 January 2026 are not the only boundaries on what a UK welcome offer can do. The CAP Code, enforced by the ASA, governs how offers can be marketed: advertising must be socially responsible, must not be of strong appeal to under-18s, and no one who is or seems to be under 25 may appear gambling in the advertisement itself. The Gambling Commission’s LCCP applies on the operator side: terms must be transparent, significant conditions must be brought to the customer’s attention before the customer opts in, and the customer must be able to withdraw funds without being pushed to forfeit an active bonus.

What the rules do not permit is the offer structure that some offshore books still run. A 50x wagering requirement is now unlawful at a UK-licensed operator. A “bet £10, get £100 in casino spins” bundle where the casino play is a condition of the sports bonus is now unlawful. A bonus that credits only after the customer has deposited twice is now harder to defend. The shape of the UK welcome offer in 2026 is narrower than the shape of the offer a Curaçao-licensed book would write, and the cap is the reason.

The licence test every operator here clears

Every brand in the featured set holds a Gambling Commission remote licence for Great Britain. The licence is the test; the Commission’s public register is the place to check it. The register can be searched by business name, trading name, domain or account number, and lists the categories of licence each operator holds. The featured brands hold a remote general betting standard (real events) licence — the category that covers pre-match and in-play sports betting — and they are GAMSTOP members as a condition of that licence.

The licence number and the licence holder are the two pieces of information the register carries that matter for a customer. Coral’s UK operations sit under LC International Limited, account 54743. Betway’s UK licence is account 39372, held by Betway Limited. BetVictor’s UK licence is account 39576, held by BV Gaming Limited. Hollywoodbets’ UK licence is account 53028, held by Hollywoodbets International UK Limited. Unibet’s UK site is run by Platinum Gaming Limited, Gibraltar, under account 45322. Paddy Power’s UK licence is account 39439, held by PPB Counterparty Services Limited. Copybet’s UK licence is account 53774, held by Copybet UK Limited. London Bet’s UK licence is account 66162, held by Thistle Bet Limited. 10bet’s UK licence is account 43173, held by Blue Star Planet Limited. Sky Bet’s UK licence is account 67370, held by SBG Sports Limited. BetUK’s UK licence is account 39198, held by LeoVegas Gaming PLC. Kalooki Sportsbook’s UK licence is account 57730, held by Kalooki Sports Book Ltd (company number 12938274). Midnite’s UK licence is account 101839.

A licence is not a ranking. Several brands in the featured set run under one parent company; Ladbrokes and Coral both sit under LC International, for example, Paddy Power and Betfair under Flutter. The customer comparing welcome offers is comparing offers, not operators’ corporate structures.

How a bettor reads a UK promo code page

The order in which a promo code page is best read is the order in which the cost is paid. First, the headline: how much comes back for how much staked. Second, the qualifying bet: minimum deposit, minimum stake, minimum odds, eligible payment routes. Third, the free bets: how many tokens, what value, what minimum odds, what expiry. Fourth, the fine print: maximum winnings, market exclusions, stake-returned or stake-forfeited. Sixth is a typo; the fine print comes fifth, and is the part the marketing copy tends to skip.

This page follows that order through the ten featured brands.

The ten UK bookmakers covered below

The ten brands covered in the ranking below are the ones that hold a Gambling Commission remote licence, run a UK-facing sportsbook in 2026 and publish a sign-up or ongoing promotion that can be read against the Commission’s promotion rules. They are not ranked by offer size; the headline numbers are too different to compare on a single axis. The list below follows a fixed order, not a ranking.

Unibet, Paddy Power, Copybet, London Bet, Betway, 10bet, BetVictor, Hollywoodbets, BetUK and Sky Bet are the ten. Each carries a heading with the brand name and the one feature that distinguishes it in the comparison: the bet builder, the welcome offer, the in-play offering, or the spread-betting dual licence. The headings are the reader’s index.

Responsible gambling and what a promo code page should not be

A page on promo codes is a page about offers, and offers are not the whole of what a UK-licensed bookmaker does. Every brand in the featured set is a GAMSTOP member, and a customer who has self-excluded through GAMSTOP cannot use these offers. Every brand offers deposit limits, loss limits and wagering limits as safer gambling tools; DAZN Bet, for instance, makes all three available on the account page. Every brand routes the customer to GamCare (National Gambling Helpline), GambleAware and the NHS gambling clinics if the customer asks for help.

What a promo code page should not do is pretend the offer is the value. The offer is a marketing spend on the operator’s side and a friction point on the customer’s side, and the value is in the betting afterwards. A customer who is claiming a welcome offer because they want to bet should bet; a customer who is claiming one because they want the offer should not. The line is the bettor’s, not the brand’s.

The legal frame around the offer

Every welcome offer in the featured set sits inside a legal frame that runs deeper than the promotion rules. The Gambling Act 2005 covers Great Britain; Northern Ireland sits outside the Act under its own older law, and a “GB-licensed” brand is licensed for England, Scotland and Wales but not Northern Ireland. The Gambling (Licensing and Advertising) Act 2014 brought offshore operators into the GB licensing regime at the point of consumption: a Curaçao, Maltese or Gibraltar licence is no substitute for a Commission licence, and operating without one carries criminal exposure for the operator under section 33 of the 2005 Act.

The customer side is not criminalised. There is no offence aimed at a customer who bets with an unlicensed operator; the cost of doing so is the loss of consumer protection — no GAMSTOP coverage, no Commission complaints route, no approved dispute resolution, no recourse if the operator withholds funds, no application of the 10x bonus cap or the £150 vulnerability check. A licensed operator charges a price in verification and in margin; an unlicensed one charges a price in exposure.

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, pool betting and in-person betting stay at 15%. Until 1 April 2027 the remote rate stays at 15%. Whether operators pass the duty on through odds is not established; the customer should not assume they do, and should not assume they do not.

Comparison table: licences and offer mechanics

Licence details above were verified against the Gambling Commission’s public register on 16 October 2026.

The brands in detail

Unibet — the longest-running welcome offer on the page

Unibet has operated since 1999. Its UK site runs on Platinum Gaming Limited’s Commission account 45322, and the headline welcome offer is the same shape as Coral’s: £20 in, £40 in free bets out, at minimum odds of 2.0 (1/1), with free bets expiring within seven days of issue, debit card or instant bank transfer funding only. The parallel structure is not coincidence; the parallel is the standard the UK market settled on.

What sets Unibet apart is the depth of the in-play and product offering that sits behind the welcome offer. Unibet runs Bet Builder for same-game multiples, daily price boosts (Uniboosts), live streaming through Unibet TV across football, tennis and horse racing, in-play betting across most sports, Best Odds Guaranteed on UK and Irish horse racing, and Cash Out across thousands of markets. For a customer whose interest is what to do with the free bets once they land, Unibet is one of the deeper catalogues in the featured set.

The trade-off is the welcome offer’s narrowness. A £40 free bet bundle against a £20 qualifying bet is competitive but not generous, and the seven-day expiry on the free bets is the same as the rest of the market. The cost-side calculation is the Coral one; the choice between Coral and Unibet is the choice between which catalogue of ongoing markets the customer wants the free bet spent on.

Paddy Power — the bet builder and the Super Sub

Paddy Power’s UK licence sits under PPB Counterparty Services Limited, account 39439. The brand’s distinctive features are the bet-builder suite and the Super Sub rule: under Super Sub, a bet on a player to score, to be carded or to make a specific play rolls over to the substitute if the selected player is taken off. The rule is small in print but large in practice — it removes one of the standard bookmaker edges on player markets.

The app also exposes Popular Bet Builders, the expanded Win More markets, and player and ACCA stats within the bet slip. For a customer whose interest is the bet-builder mechanics rather than the welcome offer headline, Paddy Power is the more considered option. The customer who wants the welcome offer to land on the simplest possible qualifying bet may prefer Coral or Betway.

The Super Sub rule is the brand’s quiet value. It costs the bookmaker margin on every bet it covers; it gives the customer a bet that does not die with the first substitution. In a market where player markets are the fastest-growing segment, this is a structural choice on Paddy Power’s side.

Copybet — the acca booster and the daily boost

Copybet’s UK licence sits under Copybet UK Limited, account 53774. The brand’s headline feature is the Acca Booster: a cash bonus of up to 100% on accumulators of three or more selections, scaling with the number of legs. The Daily Profit Boost of up to 15% is the parallel feature on singles and smaller multiples.

Copybet is the brand in the featured set whose offer is built around the multi-leg bet rather than the single. A customer whose interest is accumulators finds the structure designed for them; a customer whose interest is singles or each-way horse racing finds less reason to be there. The 100% cash bonus on a winning acca — paid as cash, not free bet — is the part of the offer the marketing copy leads with, and the part that distinguishes Copybet from the rest of the featured set, where the welcome bonus is a free bet bundle rather than a cash boost.

The cash nature of the bonus matters for the maths. A free bet bonus at minimum odds of 2.0 is worth roughly half its face value in expected profit. A 100% cash boost on an acca at the same minimum odds is worth its full face value minus the market margin, because the boost pays as cash alongside the winnings. The two are different offers on the same headline number.

London Bet — the smaller catalogue, the tighter terms

London Bet’s UK licence sits under Thistle Bet Limited, account 66162. The brand’s app carries a 17+ App Store age rating, and its market position is the smaller, UK-facing bookmaker. The catalogue is narrower than the larger brands; the welcome offer terms are simpler.

The customer who chooses London Bet is choosing a smaller bookmaker with a less crowded betting slip and fewer ongoing promotions. The trade-off is catalogue depth for simplicity: a smaller bookmaker does not run the cross-product bundles the larger brands use to keep customers on-site, and a smaller catalogue means the welcome offer’s qualifying bet is easier to place at minimum odds on the market the customer actually wants.

Betway — the four-token welcome bundle

Betway’s UK licence sits under Betway Limited, account 39372. The headline welcome offer is the four-token bundle: deposit and bet £10 or more at minimum odds of 2.0, receive £40 in free bet tokens (4 × £10), with a seven-day expiry and debit card deposits only. The structure is identical to Coral and Unibet in shape and slightly smaller in scale at the bottom (the £10 qualifying bet rather than £20).

The four-token split matters for how the free bets can be spent. A single £40 free bet has to be spent as one stake; four £10 free bets can be spread across four selections, each at a different price. For a customer who wants to spread the bonus across multiple events rather than concentrate it on one, the Betway structure is friendlier than Coral’s single-bundle structure.

The debit-card-only funding rule is the friction point. A customer funding through an e-wallet that is not connected to a debit card cannot claim. This is the same friction Coral and Unibet run, and the same as the rest of the UK market.

10bet — the percentage-match bonus headline

10bet’s UK licence sits under Blue Star Planet Limited, account 43173. The app advertises a 100% up to £50 betting bonus for UK sign-ups, with daily free bets and free spins in the app. The headline is a percentage-match structure rather than a free-bet-for-bet structure.

The percentage-match bonus is the older style of welcome offer, and it sits more comfortably under the 10x cap than the older 50x wagering requirement it used to carry. A £50 bonus at 10x wagering is £500 of qualifying turnover, which the cap allows but does not make light work of. The expected cost of clearing depends on the market the turnover is run through; on a 5% margin football 1X2 market the cost is £25; on a higher-margin novelty market it is more. The 10bet customer should treat the £50 headline as the upper bound, not the expected value.

BetVictor — the ongoing boosts and the bookmaker’s house style

BetVictor’s UK licence sits under BV Gaming Limited, account 39576. The brand runs regular price boosts, acca offers and free bets on selected events, with the welcome offer shown in the app and governed by the customer terms and conditions. The brand’s house style is the ongoing bookmaker: the welcome offer is the on-ramp, the ongoing boosts are the daily visit.

A customer whose interest is daily price boosts rather than a single welcome bundle finds BetVictor’s structure more honest than the percentage-match brands. A boost on an existing price is a clear value: the boosted price, the original price, the difference. A welcome offer is a complex set of conditions the customer must read. BetVictor’s brand is built around the former.

Hollywoodbets — the stake-back structure

Hollywoodbets’ UK licence sits under Hollywoodbets International UK Limited, account 53028. The welcome offer runs the other way from the rest of the featured set: the customer deposits £10 or more by card, places a qualifying accumulator with three or more legs at combined odds of 4/1 or greater, and if the accumulator loses, gets the stake back as a free bet of up to £30. One free bet per customer.

The stake-back structure is the “risk-free” offer the marketing copy likes, with the mechanism of a stake-not-returned free bet. The free bet is issued only on a loss, which means the customer has to want to bet the accumulator anyway to make the offer pay. The 4/1 minimum combined odds is a longer floor than the rest of the market, which means the qualifying bet is on a higher-margin market — the bookmaker is paying for the free bet with the margin on the qualifying selection.

For a customer who would have bet the accumulator at those odds anyway, Hollywoodbets’ offer is the cleanest hedge in the featured set. For a customer who is choosing the accumulator to chase the free bet, the offer is the most expensive in the featured set.

BetUK — the football-shaped free bets

BetUK’s UK licence sits under LeoVegas Gaming PLC, account 39198. The welcome offer is shaped around football: deposit £10 or more, place a sports bet within seven days of registering, receive four £10 free bets — two football accumulators of four or more legs and two multiples of two or more selections — valid for seven days, with opt-in required. The structure of the free bet bundle steers the customer toward football and toward accas.

For a customer whose interest is football accumulators, the BetUK bundle is a clean fit. For a customer whose interest is horse racing or another sport, the two football-shaped tokens are wasted and the other two are general. The structure is the brand’s signal about who it is for.

Sky Bet — the lowest-stakes qualifying bet

Sky Bet’s UK licence sits under SBG Sports Limited, account 67370. The headline welcome offer is the smallest qualifying bet in the featured set: deposit £5, place a single or each-way bet of at least 5p at odds of 1/1 or greater, and receive £30 in free bets as three £10 tokens. The 5p minimum stake means the qualifying bet can be placed for less than the cost of a stamp.

The 5p stake is the structural oddity in the featured set. A £30 free bet bundle against a 5p qualifying bet is the most generous headline ratio by an order of magnitude, and the cost of the offer sits entirely in the free bet conversion rate rather than the qualifying bet. For a customer who wants to test a brand without committing stake, Sky Bet’s offer is the lowest-cost way in.

The trade-off is that the brand’s ongoing catalogue is the Sky Bet catalogue — a strong horse racing and football book with the Sky Sports brand behind it — rather than the deeper catalogues at Unibet or bet365. The free bets land where the catalogue is, and the catalogue has its own centre of gravity.

Beyond the welcome offer: ongoing promos the customer will actually see

The welcome offer is the headline. The ongoing promotions are the daily visit. Coral runs a free daily Reward Shaker — a prize-draw mechanic on a free-to-play game — and an Odds Booster on hundreds of markets, plus free-to-play games including Football Super Series with a £10,000 jackpot. Unibet runs the daily Uniboosts. William Hill’s Football Acca Boost covers accas of two or more legs at minimum odds of 1/5 per selection, with a boost from 3% on a double up to 200% on twenty or more legs and a maximum boost of £10,000 per online bet, running until 30 May 2027. BoyleSports runs an Acca Insurance offer that refunds losing accas as a free bet up to £20 (opt-in, £5 minimum stake, minimum odds of 1/2, same-day settlement) and an Acca Loyalty offer on five or more settled legs at combined odds of 3/1 or greater.

bet365 runs Bet Builder+ combining markets from one event into a single bet (available pre-match and in-play), Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. Kwiff’s Supercharge feature can instantly boost the odds on a bet — the example on the App Store listing is from 2/1 to 20/1 — and it applies to single or multi bets on any sport. Kwiff also offers Bet Builder, Bet Builder+ (combining Bet Builder bets from different games) and a guaranteed weekend acca boost. Spreadex’s Acca Boosts give a cash boost from 5% up to 100% on football accumulators of three or more selections, depending on the number of legs. Smarkets’ sister product SBK offers Cash Out, Bet Builder and live horse racing streams alongside its welcome offer. Star Sports runs Bet Boosts, Daily Specials and Weekend Enhanced Boosts, with in-play betting on football, horse racing, golf and US sports. DAZN Bet runs Cash Out (cash out availability is not guaranteed and bets stand if it is unavailable), Bet Builder, daily bet boosts and in-play betting.

Paddy Power’s app exposes Bet Builder+, Popular Bet Builders, Super Sub, expanded Win More markets and player and ACCA stats. The Paddy Power bundle is the deepest ongoing-product bundle in the featured set, and the closest to a one-stop bettor app.

The free daily Reward Shaker at Coral, the Uniboosts at Unibet, the Football Acca Boost at William Hill, the Bet Builder+ at bet365, the Supercharge at Kwiff, the Super Sub at Paddy Power — these are the ongoing promotions that pay the bills of the brands that run them. None of them is a welcome offer; all of them are what the customer is buying with the loyalty the welcome offer was meant to lock in.

What the promotion rules do not do

The promotion rules in force since 19 January 2026 close off two structures: 50x wagering requirements and mixed-product bundles where one product is conditional on the other. They do not close off the rest of the welcome offer shape. Free bet tokens with seven-day expiries, minimum odds floors, debit-card-only funding and stake-not-returned mechanics are all still on the market.

The rules also do not bind the offshore market. A Curaçao-licensed book can run a 50x offer, a mixed-product bundle and a longer expiry. The customer gains in headline size and loses in consumer protection — no GAMSTOP coverage, no Commission complaints route, no approved dispute resolution. The trade-off is the customer’s, not the page’s, but the page notes it.

The rules also do not bind the spread betting market. Spreadex’s fixed-odds welcome offer is governed by the Commission; Spreadex’s spread betting offer is governed by the FCA, and the spread betting side carries a separate risk profile. Losses on spread bets can exceed the deposit; the customer who spreads across both sides of Spreadex’s offer is taking on a different risk than the customer who sticks to fixed odds.

A worked turn on the page’s own maths

The bonus-turnover calculation is the page’s worked example. The inputs are Coral’s headline offer: bonus amount £40, no separate wagering multiple on the free bet itself (free bet, not bonus), minimum odds 2.0 on the qualifying bet, expiry seven days. The 10x cap in force since 19 January 2026 is the regulatory ceiling. A £40 bonus at 10x wagering would be £400 of qualifying turnover — but the Coral offer is a free bet bundle rather than a cash bonus with turnover, so the 10x cap applies only if Coral structures the offer as a bonus with turnover, which its own terms do not.

For a £50 betting bonus at 10x wagering with a £10 stake per bet and a minimum odds floor of 1/2, the calculation is as follows. The required turnover is £500. The number of bets is fifty. The cost of clearing depends on the market; on a football 1X2 market with a 5% margin, the expected cost is £25. On a horse racing market with a 15% margin, the expected cost is £75. The band — £25 to £75 — is the cost of clearing the £50 bonus, conditional on the market the customer chooses.

The band is the information. The headline is £50; the cost is between £25 and £75, and the spread is in the customer’s choice of market. A customer who clears the bonus on football pays less than a customer who clears it on horse racing; a customer who clears it on novelty markets pays more.

Where the spread of licences shows in the offer

The ten featured brands hold ten different Gambling Commission licences, and the licences differ in age, in parent company and in the categories beyond remote general betting standard (real events) that they cover. Several brands — Unibet, Betway, Paddy Power, Coral — run parallel products in casino and bingo under the same parent; others — Copybet, Hollywoodbets, BetUK — run sports-only catalogues under the Commission licence. The customer comparing welcome offers is also comparing the brand’s commitment to the sports product alone.

Spreadex’s dual regulation — FCA for spread betting, Gambling Commission for fixed-odds betting — is the structural outlier. The customer who takes Spreadex’s £60 fixed-odds welcome offer is also taking a position with a firm that runs a separate product under a separate regulator. The dual regulation is not a flaw; it is a feature, and it is the only one of its kind in the featured set.

Midnite, Kalooki Sportsbook and London Bet are smaller names with full Commission licences. Midnite’s licence is account 101839, and its site shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. Kalooki Sportsbook is operated by Kalooki Sports Book Ltd (company number 12938274), licensed under account 57730 and is a GAMSTOP member. London Bet is published by Thistle Bet Limited. The smaller brands are not lesser-licensed; the licensing regime is the same across them.

What the comparison leaves out

The comparison above leaves out four things on purpose. It does not include a brand’s customer service quality, because no comparable metric exists across the featured set; it does not include the catalogue depth in any number, because the catalogue is too varied to compress into a single column; it does not include the withdrawal time, because the withdrawal time depends on the payment method chosen rather than on the brand; and it does not include the operator’s parent company revenue or market share, because the customer is comparing offers, not balance sheets.

What the comparison does include is the licence, the licence holder, the welcome offer headline and the key ongoing product feature. The four columns are the four pieces of information the customer needs to decide which welcome offer to claim. The rest is in the customer’s own reading of each brand’s catalogue.

The verdict on the ten

Ten brands, ten welcome offers, one promotion regime. The shape of the offer is uniform; the differences are in scale, in the free bet split, in the qualifying bet floor and in the ongoing catalogue the free bets land on. The customer comparing on headline alone is comparing £40 of free bets at Coral and Unibet, £40 of free bets split four ways at Betway, £30 of free bets split three ways at Sky Bet, a £30 stake-back at Hollywoodbets, a £50 percentage-match at 10bet and four £10 tokens split between football accas and multiples at BetUK.

The choice is not “best offer”. The choice is which offer’s terms and ongoing catalogue the customer wants to live with for the seven-day free bet window and beyond. Coral and Unibet are the cleanest, largest headline; Sky Bet is the lowest-cost entry; Hollywoodbets is the stake-back hedge; BetUK is the football-shaped bundle; Betway is the four-token split; 10bet is the percentage-match structure with the heavier turnover load; Copybet is the acca-booster structure for the multi-leg punter; BetVictor is the ongoing-boosts brand for the daily visitor; Paddy Power is the bet-builder-and-Super-Sub brand for the player-markets customer; London Bet is the smaller-catalog brand for the customer who wants a simpler bookmaker.

This page describes the offers; the reader decides which offer is worth the registration. The licence is the floor every offer sits on; the rest is the customer’s arithmetic.

Frequently asked questions

How does a UK bettor actually use a promo code?

A UK bettor enters a promo code at registration or in the cashier, or — for most welcome offers in 2026 — ticks an opt-in box before placing the qualifying bet. The code is the on-switch for the offer; the substance is the qualifying bet, the minimum odds, the free bet value, the expiry window and the payment route. Read the offer’s terms before depositing, because the qualifying bet must meet the minimum odds floor and the deposit must come from a debit card or instant bank transfer at most UK-licensed brands to count.

What is the maximum wagering requirement on a betting bonus in Great Britain?

Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x the bonus amount. A £10 bonus can require no more than £100 of qualifying turnover; a £50 bonus can require no more than £500. Whether the cap applies to free bets with no wagering condition is not established. Mixed-product promotions — an offer that requires gambling on betting and casino at once — are also banned under the same rule set.

What do minimum odds and the wagering requirement mean in a sign-up offer?

The minimum odds is the floor the qualifying bet must clear for the offer to unlock — Coral’s £40 free bet offer requires the qualifying bet to be at minimum odds of 2.0 (1/1), for instance. The wagering requirement is the multiple of the bonus the customer must turn over before the bonus is withdrawable — a £50 bonus at 10x wagering is £500 of qualifying bets. Higher minimum odds and higher wagering requirements both raise the cost of clearing the offer; the cap limits the wagering requirement, not the minimum odds.

Why is the stake of a free bet not paid back with the winnings?

A stake-not-returned free bet returns only the profit on the bet, not the stake itself. A £10 free bet at 5/1 returns £50 in profit, not £60. A stake-returned free bet — sometimes called a “risk-free” bet — returns both. Most UK welcome offers in 2026 are stake-not-returned; the marketing language of “free” hides the fact that the £10 token’s expected value is closer to £5 than to £10, because the stake is forfeit and the bet is on a margin-loaded market.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?

No. The promotion rules in force since 19 January 2026 ban mixed-product promotions: an offer may not require a customer to gamble on two or more product types — betting, casino, bingo, lottery — as a condition of receiving the bonus. Bundles where casino play is optional are still possible; bundles where casino play is conditional on the sports bonus are not. The rule is the closing of the “bet on football to unlock free spins” structure that several brands used to run.

How can a bettor check that a bookmaker holds a Gambling Commission licence?

The Commission’s public register — at the Commission’s own site — can be searched by business name, trading name, domain or account number. The register lists the licence holder, the licence number, the categories of licence the operator holds, and the licence status. Every brand in the featured set holds a remote general betting standard (real events) licence and is a GAMSTOP member. A licence is the floor, not a ranking: the register lists every licensed brand, and there are far more licensed brands than any one page can cover.

What this page does not say

This page does not name winners. It does not name the bookmaker with the “best” welcome offer, because no bookmaker has the best offer for every customer. It does not predict which selections to back, because the page is about offer mechanics, not about outcomes. It does not carry a tipster line, and it does not print a working promo code, because the offer value is in the terms and not in the code.

The page does say what the offers cost, in terms of qualifying turnover, expected loss, minimum odds floors, expiry windows and consumer protection. The arithmetic is the page’s information. The customer’s bet is the customer’s bet.
