A sign-up offer is a marketing line dressed up as a gift. The headline number — £30, £40, £60 in “free” bets — is what a bookmaker wants the customer to remember; the conditions that come attached decide what the bundle is actually worth. In Great Britain the spend on those conditions now sits inside a Commission cap that took effect on 19 January 2026, and the only honest way to read any welcome package is to ask what it costs the punter before the bonus number even enters the picture. That is the question this guide was written to answer.

What follows is a working-over of ten UK-licensed bookmakers against that single question. The promotion rules are the frame; the offers themselves are the material inside it. The arithmetic is a statistical estimate, not a prediction — no calculation knows the outcome of a real bet, and nothing in this guide names one.

The statute book a free bet sits inside

The Gambling Act 2005 is the framework. It is administered by the Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport. It covers Great Britain — England, Scotland and Wales — and not Northern Ireland, where an older regime still applies. Since the Gambling (Licensing and Advertising) Act 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it sits, so a Curaçao or Maltese licence alone does no work in a British front room. There is no state monopoly and no limit on the number of licences the Commission can issue.

The Act splits the betting side into licence categories. Remote general betting standard (real events) is the everyday one — the licence that lets a bookmaker take bets on football, horse racing, tennis and the rest of the live calendar. Remote general betting standard (virtual events) is its own category for computer-simulated sport. Remote general betting limited sits below that, for smaller operators. Remote pool betting covers Tote-style and off-course horse and greyhound pool products. Remote betting intermediary is the exchange licence, held by brands such as Smarkets. Every brand in this guide sits under one of these categories, and the Commission’s public register is the only honest test of whether a name on a website is the same as a name on a licence.

The Commission’s Licence Conditions and Codes of Practice (LCCP) do most of the work a punter feels. They sit on top of the Act and bind every licensee. Three LCCP clauses shape the welcome offer more than anything the bookmaker writes.

Minimum age and verification: 18 is the entry point, and the operator has to verify name, address and date of birth before a customer can deposit or place a bet, including when the bet is paid for by a free bet or bonus. There is no anonymous play at a licensed site.

A financial vulnerability check has been in force since 30 August 2024 under LCCP condition 3.4.4. Once a customer’s deposits minus withdrawals cross £150 in a rolling 30 days, the operator runs a public-record check — bankruptcy registers, county court judgments — not a credit reference and not an income check. The “affordability checks” of the press are a separate, staged plan announced on 7 July 2026 with no start date.

A credit-card ban has been in place since 14 April 2020 (LCCP condition 6.1.2). No gambling payment at a licensed operator can ride a credit card, including via an e-wallet funded by one. Debit cards and bank-based payments are not covered by that ban.

The 19 January 2026 promotion rules

Two rules changed the welcome offer on 19 January 2026. Both are Commission rules, not operator rules, and both apply to every licensed bookmaker. They are the reason the headline numbers in this guide are read with one eyebrow raised.

Wagering requirements on bonuses are capped at 10x. A £10 bonus with a 50x wagering requirement used to mean £500 of qualifying bets before anything could be withdrawn; under the cap, no bonus can ask for more than £100 of qualifying turnover. The cap attaches to the bonus, not the deposit. A £10 deposit bonus that demands 50x the deposit is asking for £500 of bets and is now out of bounds.

Mixed-product promotions are banned. An offer that makes a customer gamble on two or more product types — a football bet tied to free spins, a sportsbook deposit tied to a casino bonus, a betting bonus bundled with bingo or lottery play — is not permitted. A sportsbook-only welcome package sits inside the rules; a package that crosses into casino does not.

What the cap does not settle: whether it applies to a free bet with no wagering condition at all, and whether there is any cap on the money value of a bonus itself. Neither is established in the rules. The £40-in-free-bets headline that several brands still publish is unchanged in size by the cap; what changed is what surrounds it.

Tax and what the punter actually pays

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15%, with a new remote betting rate of 25% applying from 1 April 2027 inside it. The remote rate stays at 15% until that date. The Commission’s statutory levy is a separate charge paid by operators and is not a tax on winnings.

Whether operators pass duty on through tighter odds is not established. The honest framing is that the margin inside every price already reflects what the bookmaker pays the Treasury; the punter pays it indirectly, as part of the price, or not at all — never as a separate line on the slip.

Offshore and what a GB licence buys

A GB licence is compulsory at the point of consumption. Operating in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005 — aimed at the operator, not the customer. No offence aimed at a punter who simply bets on an unlicensed site was found, so the framing is not “illegal to use”. The framing is the loss of protection: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no 10x bonus cap, no £150 vulnerability check. None of those protections is “the safe choice” by default — they are simply what a GB licence buys, alongside the verification check before the first bet.

Safeguards a welcome offer has to live alongside

A sign-up offer is not the only thing a GB-licensed bookmaker puts on a new account. The Commission ties a marketing licence to a set of safer-gambling duties, and the welcome offer sits inside them rather than beside them.

GAMSTOP is the national multi-operator self-exclusion scheme. It has been a mandatory licence condition for online operators since 31 March 2020. The minimum period is six months, with options of one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in force for a further seven years unless the customer asks GAMSTOP to remove it. Every brand in this guide is a GAMSTOP member, and a self-excluded customer is barred from the welcome offer as firmly as from any other bet.

The 18-plus age rule and the identity check mean the welcome offer cannot be claimed anonymously. A new account asks for name, address and date of birth and verifies them before the first deposit; a free bet or a bonus is paid out only once the check is clean. From the operator’s side this is anti-fraud; from the punter’s side it is the price of every protection the licence provides.

Deposit limits are now under the Remote Technical Standards. The first changes have applied since 31 October 2025, with a second phase postponed to 30 September 2026; whether that second phase is live is not established. There is no state-set ceiling — limits are the customer’s choice.

Help exists outside the operator. GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. NHS gambling clinics operate in several regions. Gamblers Anonymous runs local meetings. A punter who has stopped enjoying the welcome offer is not alone in the problem, and the support lines do not need the welcome offer to be settled before they take a call.

What a sign-up offer really is

A sign-up offer is one of four shapes, and each shape carries a different cost to the punter. Naming the shape is the first step in reading the offer.

Free bet. The bookmaker credits a stake — £5, £10, £30 — and the punter places a bet with it. Two rules sit inside: the stake is usually not paid back with the winnings, and the free bet expires on a deadline the bookmaker sets. A £10 free bet at odds of 3.00 on a winning selection returns £30 in cash: the £20 profit, with the original £10 stake forfeited. That forfeiture is the free-bet convention in British usage and is what most operators call “stake not returned”.

Bet credit. Functionally similar to a free bet, but the stake can be paid back on a win at some brands. The terminology is not consistent across the market; the rule is to read the terms each time.

Risk-free bet. A first bet that is refunded as a free bet or credit if it loses. The refund is not a refund in cash. The name is a marketing word.

Deposit bonus. The bookmaker matches a percentage of the first deposit in bonus funds, subject to a wagering requirement. A 100% deposit bonus on £20 is £20 in bonus, with the wagering requirement to clear it. Under the 10x cap that requirement is bounded by £200 of qualifying bets on a £20 bonus; above 10x the offer is out of bounds for a GB-licensed operator.

Across those four shapes the only number a punter controls is whether to claim at all.

Minimum odds and wagering requirements

Two clauses sit inside almost every sign-up offer, and they decide most of the cost.

Minimum odds state the lowest price a qualifying bet must be placed at to count toward the offer. A £20 free bet that demands minimum odds of 2.0 (1/1) cannot be used at 1.5 (1/2). The clause keeps the punter away from heavy odds-on favourites, where a win is cheap and the offer costs the bookmaker little.

Wagering requirements state how many times the bonus has to be turned over before winnings can be withdrawn. A £10 bonus with a 5x wagering requirement needs £50 of qualifying bets. The 10x Commission cap binds both bonus and deposit terms. A bonus with no wagering requirement is a different shape — the punter keeps the winnings from the free bet itself without rolling them over, subject to the stake-not-returned convention.

Both clauses can sit on the same offer. They are the bookmaker’s reading of how much turnover the bonus has to fund before it becomes real money.

Expiry, withdrawals and what is excluded

Free bets expire. The expiry ranges from seven days to thirty days in the offers below; the figure is named in each operator’s terms. An expired free bet is gone and is not reissued.

Free bets are usually non-withdrawable. The punter cannot cash the £10 in free bets out as £10; the value sits inside the betting account and is spent on a bet. The winnings from a winning free bet, by contrast, are withdrawable subject to any wagering condition.

Several markets are commonly excluded. Virtual events are frequently named. Each-way bets may or may not count. Multiples are sometimes excluded, sometimes allowed. The terms are operator-specific and the punter reads them before placing the qualifying bet.

The arithmetic of a free bet

The free-bet value is the average worth of a free bet across many uses, not the size of the credit.

For a free bet whose stake is not paid back, the value of the bet is the free-bet amount times the decimal odds minus one, divided by the decimal odds, times the payout share of the market. Take an illustrative two-way market at decimal odds of 1.90 and 1.9. The payout share is one divided by the sum of one over each outcome: 1 ÷ (1/1.9 + 1/1.9), which is roughly 0.95, giving a margin of about 5%. A £10 free bet on a winning selection at decimal odds of 1.9 pays £19 in cash; the stake is forfeited. The expected value of the bet is its probability of winning times the return on a win, integrated over the market: about £9.50 in expectation, in this example.

The honest statement is a band, not a single figure, because the market a punter chooses shifts the value. On a 1.90 / 1.90 market a £10 free bet is worth roughly £9.50 on average. On a 3.00 / 3.00 market with a heavier margin it is worth less; on a near-even-money market with a tighter margin it is worth closer to £10. The free bet is a fraction of its face value, and the fraction is set by the market the punter picks.

What the same offer looks like with a wagering requirement

A £10 bonus with a 5x wagering requirement needs £50 of qualifying turnover. At a £5 stake per bet that is ten bets, each at minimum odds of 1.75 or higher in the terms that name it. The expected cost of clearing the bonus is the turnover times the margin of the market those qualifying bets are placed on: £50 times 5% is £2.50 of expected cost on a market with a 5% margin. The bonus is worth £10 nominal; the punter gives up £2.50 of expected margin to clear it. A 10x cap means the maximum expected cost on a £10 bonus is £5 of margin on a 5% market.

These numbers are statistical averages, not guarantees. They describe what the offer costs across many uses; they say nothing about the outcome of a single bet.

Comparing the ten

The table below compares ten UK-licensed bookmakers on the same four points. The brand column carries the name as it appears on the Commission’s public register. The licence column carries the Gambling Commission remote licence number and the licence holder, taken from the register against the domain each brand publishes. The offer column carries the offer’s headline and its qualifying conditions in the operator’s own words, to the depth research found.

The table is a working map, not a ranking. Two rows matter most for the cost question: rows where the headline carries a casino bonus (Octobet, 10bet) and rows where the headline carries a stake-returned refund on a loss (Hollywoodbets). Both shapes are addressed below — the mixed-product case in the analysis of those brands, and the stake-returned case in the free-bet arithmetic.

The ten UK-licensed bookmakers, in detail

The plan routes ten operators into the ranking. The order is the order research found them on the Commission’s register against a remote betting licence for Great Britain. Each block closes on a verdict that names the cost, not the brand’s suitability for an unnamed reader.

Swifty Sports — the in-play newcomer with a light welcome line

Swifty Sports sits under Swifty Global (UK) Ltd with a Commission account of 58957, covering remote general betting standard (real events). The site publishes Best Odds Guaranteed, Cash Out on horse racing and football, daily price boosts, live streaming and in-play markets; Bet Builder is listed as coming soon rather than live.

No separate welcome-bonus headline appears in the same terms page research could verify. The arithmetic of a missing welcome line is straightforward: a punter who values in-play and streaming gets the full feature set on day one, and the absence of a headline bonus means there is no wagering requirement, no expiry, no stake-not-returned rule to budget against. The cost is the cost of the margin on every bet they place.

For a punter who bets heavily in-play and wants Best Odds Guaranteed on horse racing from a Commission-licensed bookmaker, Swifty Sports is a usable starting point with the welcome line treated as zero. For a punter whose first concern is the size of the welcome credit, the brand reads thin against the £40-in-free-bets competitors in the table. The verdict: a credible in-play bookmaker whose welcome line is so understated the punter should check the site’s promotions page directly, because what research could verify is lighter than what a casual reader expects.

BetGoodwin — three small free bets and a racing tilt

BetGoodwin sits under Goodwin Racing Limited with a Commission account of 2927. The headline is “Bet £10 & Get £15 in Free Bets”, built from a £5 sports bet, a £5 acca and a £5 Sub-Cover bet. The split is the offer’s first feature: three different bet shapes for £15 of nominal credit.

Each slice carries its own expiry, market restriction and minimum-odds rule in the terms the operator publishes; none of the slices is a cash bonus, so the 10x wagering cap does not bind the headline, but each slice is non-withdrawable and stake-not-returned. The Sub-Cover bet is the unfamiliar term and refers to a specific market Goodwin Racing runs on horse racing; a punter who does not bet horse racing leaves one of the three slices unused.

For a racing punter who already uses Sub-Cover markets, the offer is a clean three-slice welcome. For a football-only punter, the £5 acca slice is the working one and the other two are a slow bleed against the headline. The verdict: an honest offer for the audience it was written for, less so outside it.

Betboro — a matched free bet with a high minimum-odds clause

Betboro sits under Webmedia Development N.V. with a Commission account of 44181. The offer is a 100% matched free bet of up to £25 on the first qualifying wager, requiring a debit-card deposit of at least £10 and a first bet of £5–£25 with at least three selections each at 3/5 (1.60) or higher.

Three details cost the punter. The minimum-odds clause is set per leg, not per accumulator; a 1.55 leg voids the whole qualifying wager regardless of the other two. The deposit must be by debit card, so a bank transfer or e-wallet deposit does not qualify the punter for the offer. The offer pays the matched free bet on the first qualifying wager only — a punter who likes to bet small first and settle into the site pays the matched bonus on a small first bet.

For a punter with a debit card who plans to bet an acca on day one, the offer is clean. For a punter who deposits by bank transfer or bets singles first, the offer is a near-miss. The verdict: a matched-free-bet shape that pays best when the punter plans the first bet around it, not when the punter wanders into it.

Coral — the £40 headline on the Ladbrokes-Coral licence

Coral sits under LC International Limited with a Commission account of 54743, covering remote general betting standard (real events) and remote betting intermediary. LC International also runs Ladbrokes and a small set of related brands, so the Coral licence is the licence of a group, not of a single trading name.

The headline is “Get £40 in Free Bets when you bet £20” — a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue. The qualifying payment methods are debit card or instant bank transfer; Coral’s site lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options, but not all qualify the welcome offer. The £40 headline is non-withdrawable and stake-not-returned; the value is the £40 × (odds − 1) ÷ odds × payout share on the market the punter picks.

For a punter who already plans to deposit £20 and bet it on a single at evens or bigger, the £40 is real value at near-zero friction. For a punter whose first bet would have been a £5 acca at minimum odds, the offer demands a different first bet. The verdict: the £40 headline is generous against the table, and the cost is the friction of changing the first bet to fit it.

Geoff Banks — a small bookmaker with a thin welcome line

Geoff Banks sits under GB Sports Advisors Limited with a Commission account of 54095. The app is published by GB Sports Advisors Ltd and offers live in-play prices and ante-post prices on future events. Research did not find a separate welcome-bonus headline in the same terms page.

The arithmetic of a missing welcome line is the same as it was for Swifty Sports: no wagering requirement, no expiry, no stake-not-returned rule. The cost is the cost of the margin on every bet.

For a punter who values a small bookmaker with personal service and ante-post prices on futures, Geoff Banks is a usable place to open an account. For a punter whose first concern is the headline credit, the brand reads thin against the table. The verdict: a credible small bookmaker whose welcome line is thin to the point of being a non-claim, and a punter should treat the welcome offer as zero rather than chase a hidden headline.

Betway — four tokens and a 1x wagering tag on the free bets

Betway sits under Betway Limited with a Commission account of 39372. The welcome offer is £40 in free bet tokens (4 × £10) credited on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry and debit-card deposits only. The free bets carry 1x wagering at minimum odds of 1.75 — a clause the Commission cap does not bind, because the 1x wagering on the free bet itself sits under the 10x ceiling.

The 1x wagering on the free bet is a small but real friction: a winning free bet has to be rolled over once at minimum odds of 1.75 before withdrawal. The minimum deposit is £10. The minimum odds of 2.0 on the qualifying bet is the standard headline clause. The four-token split (£10, £10, £10, £10) is a fragmentation cost — the punter cannot place a single £40 bet on a long-odds selection, because each token is a separate stake.

For a punter who bets singles at minimum odds of 2.0 or above, the four-token split is harmless and the 1x wagering is light. For a punter who wants to put the whole £40 on one bet at long odds, the split is a working limitation. The verdict: a clean £40 headline with a 1x wagering tag that costs the punter the expected margin on one qualifying bet, and the four-token split is the friction that catches the long-odds punter.

Smarkets — the SBK sportsbook welcome behind the exchange

Smarkets sits under Smarkets (Malta) Limited with a Commission account of 39173, covering remote betting intermediary — the exchange licence. The sportsbook welcome is via SBK, Smarkets’ sportsbook brand: £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours. The free bets come with Cash Out, Bet Builder and live horse racing streams on the platform.

The 3.0 minimum odds on the qualifying bet is a heavy line. The punter has to find a 2/1 selection to claim £60 in free bets, which sits well above the 2.0 minimum on Coral’s and Betway’s equivalents. The £60 headline is the largest in the table. The trade is the qualifying bet: a punter who already plans to back a 2/1 selection on day one gets a clean £60; a punter whose first bet would have been at evens leaves the headline unused.

For a punter who backs longer-priced selections and uses the exchange and the sportsbook together, SBK is a credible home. For a punter who wants a 2/1 qualifier on day one for the £60, the offer is a clean trade. The verdict: a heavy qualifying line trades for a heavy headline, and the trade favours the punter who already bets at longer prices.

Hollywoodbets — the stake-returned free bet on a losing acca

Hollywoodbets sits under Hollywoodbets International UK Limited with a Commission account of 53028. The welcome offer is a stake-returned free bet of up to £30 on the first qualifying losing accumulator — stake £10 or more, three or more legs, odds of 4/1 or greater, settled within 7 days. One free bet per customer.

This is the closest shape on the page to a “refund” without being one in cash. The free bet is paid only if the qualifying acca loses; if the acca wins, the punter keeps the winnings and gets no free bet. The free bet is stake-returned on a winning free bet, which is the unusual clause: the punter gets both the stake and the profit on a winning free bet, instead of the stake-not-returned convention elsewhere in the table.

For a punter who plans to place a 4/1 acca on day one, the offer is a clean backstop on a loss. For a punter who would have bet singles, the offer is a near-miss. The verdict: a clean loss-back shape for an acca punter, and the stake-returned free bet is the unusual clause that lifts the offer’s expected value above the table average.

Octobet — a sports free bet tied to a £10 casino bonus

Octobet sits under Octopus Game Limited with a Commission account of 62545. The headline is 50% back as a free bet up to £50, plus a £10 casino bonus for new customers.

The £10 casino bonus on the welcome is the cost. Mixed-product promotions — an offer that asks the punter to gamble on two or more product types — are banned under the Commission’s promotion rules in force since 19 January 2026. A sportsbook welcome package that bundles a casino bonus falls inside that ban, and the headline as it was published at the snapshot date sits on the wrong side of it. A punter reading the offer today should check the site’s current promotion page, because the headline may already have been reworked to comply.

For a punter who wants a single-product sportsbook welcome only, Octobet is a brand whose headline carries the kind of clause the rules now block. The verdict: a headline that the rules now treat as out-of-bounds, and a punter should not claim the casino slice on the welcome page.

10bet — a sportsbook bonus tied to free spins

10bet sits under Blue Star Planet Limited with a Commission account of 43173. The headline is a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins.

The “plus free spins” on the welcome is the cost. Free spins are a casino product, and a sportsbook welcome that ties them in falls inside the mixed-product ban. A punter reading the offer today should check the current promotion page for the same reason as on Octobet.

For a punter who wants a single-product sportsbook welcome only, 10bet’s headline carries the kind of clause the rules now block. The verdict: a headline the rules now treat as out-of-bounds, and a punter should not claim the casino slice on the welcome page.

What the welcome offer is really worth

The arithmetic is a band, not a single figure. The free-bet value formula takes the stake, the decimal odds, and the payout share of the market; the result is the average worth of the free bet across many uses.

For an illustrative two-way market at decimal odds of 1.90 and 1.90, the payout share is one divided by the sum of one over each outcome, which is roughly 0.95 — a margin of about 5%. A £10 free bet at decimal odds of 1.9 on a winning selection returns £19 in cash; the stake is forfeited. The expected value of the bet is the probability of winning times the return on a win, integrated over the market, which comes out at about £9.50 in expectation. On a 3.00 / 3.00 market with a similar margin the expected value is higher; on a 1.50 / 1.50 market with the same margin it is lower. The free bet is always a fraction of its face value, and the fraction is set by the market the punter picks.

Across the table, the welcome offers split three ways. The first group — Coral, Betway, Hollywoodbets — pay a headline in the £30–£40 range with a 2.0 minimum-odds qualifier and standard 7-day expiry. The second group — Betboro, BetGoodwin — pays a smaller headline under a heavier minimum-odds clause or a multi-slice split. The third group — Smarkets via SBK — pays the largest headline at £60 but demands a 3.0 qualifier. The cost is the friction between the punter’s first bet and the offer’s qualifying line; the headline is what the punter receives once that friction is paid.

The Commission’s 10x bonus cap binds the deposit-bonus shapes more than the free-bet shapes. None of the offers in this guide is a deposit bonus with a heavy wagering requirement; most are stake-not-returned free bets with no rollover, and the cap is the floor that stops any future deposit-bonus headline from asking the punter for 50x turnover. The mixed-product ban is the rule that catches the Octobet and 10bet headlines, and the cap is the rule that catches anything the brands may add to them.

The honest summary is that the welcome offer is a starter credit with a price tag, and the price tag is what decides whether the offer is worth claiming. A £40 headline paid out at 1x wagering on a 1.90 / 1.90 market is worth roughly £38 in cash across many uses; a £60 headline with a 3.0 qualifier is worth more, but only to a punter who would have backed a 2/1 selection on day one. The arithmetic is a statistical estimate. No calculation can name the outcome of a single bet, and nothing in this guide names one.

Frequently asked questions about free bet sign-up offers

How does someone sign up for a betting site in Great Britain?

A punter opens an account on the operator’s site or app, provides name, address and date of birth, and verifies them before the first deposit. The check is mandatory under Commission rules and is the price a punter pays for every protection the licence provides. Once verified, the punter makes a deposit by debit card or bank-based payment — credit cards are banned for gambling — and places a qualifying bet at the minimum odds the welcome offer names. Free bets are credited on settlement of the qualifying bet and expire on the deadline the operator publishes.

How does someone sign up for a sportsbook specifically?

A sportsbook is a remote general betting standard (real events) licence under the Gambling Act 2005. The sign-up is the same as for any Commission-licensed site, but the welcome offer is sportsbook-only and the bonus cannot be tied to casino, bingo or lottery play under the Commission’s promotion rules. Mixed-product offers are banned from 19 January 2026, so a sportsbook welcome that bundles a casino bonus sits on the wrong side of the rules and should be checked on the operator’s current promotion page before the punter claims it.

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

The Commission’s promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x. A £10 bonus can ask for no more than £100 of qualifying turnover before winnings can be withdrawn; anything heavier is out of bounds for a GB-licensed operator. Whether the cap applies to a free bet with no wagering condition at all, and whether there is any cap on the money value of a bonus itself, are not established.

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

Minimum odds state the lowest price a qualifying bet must be placed at to count toward the offer; a £20 free bet that demands minimum odds of 2.0 (1/1) cannot be used at 1.5 (1/2). A wagering requirement states how many times the bonus has to be turned over before winnings can be withdrawn; a £10 bonus with a 5x wagering requirement needs £50 of qualifying bets. The two clauses can sit on the same offer and decide most of the cost; both are bounded by the 10x Commission cap.

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

The free bet is a marketing credit, not a cash stake. When a free bet wins at decimal odds of 3.0, the return is £30 in cash on a £10 free bet — the £20 profit, with the original £10 stake forfeited. The forfeiture is the British convention on free bets and is what most operators call “stake not returned”. The convention is what makes a free bet worth a fraction of its face value; the formula is the free-bet amount times the decimal odds minus one, divided by the decimal odds, times the payout share of the market.

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

No. Mixed-product promotions — an offer that requires gambling on two or more product types, such as a sportsbook deposit tied to a casino bonus — are banned under the Commission’s promotion rules in force since 19 January 2026. A sportsbook-only welcome package sits inside the rules; a package that crosses into casino, bingo or lottery play does not. The ban applies to every GB-licensed operator.
