The 10x Wagering Cap: How UK Bonus Rules Changed in 2026

From 19 January 2026, every UK-licensed casino and betting firm must keep the playthrough demand on its incentive offers at 10 times the bonus sum or lower. At the same moment, promotions that mix two product types – a sports bet with casino spins, for instance – became illegal. The two rules are the biggest single curtailment of the way operators have used bonus terms to lock in customer cash, though they don’t erase every condition customers should still be checking.

What a Wagering Requirement Actually Is

The Gambling Commission defines a wagering requirement as a situation where a customer must make wagers totalling a particular value before the bonus funds, or winnings derived from them, become withdrawable. That definition, buried in the regulator’s autumn 2023 consultation response, describes a lock. A £10 bonus with a 10x wagering obligation means you must stake £100 on eligible games or bets before you can touch the cash. The £100 is total turnover, not profit or loss. A player who churns £100 in stakes on a game with a 3.5% house edge can expect to lose £3.50 of the bonus money while trying to free it. The Commission’s rule does not pretend otherwise; it simply caps the size of the hoop.

Where the 10x Figure Comes From

The Commission’s rule, published in its autumn 2023 consultation response and given final shape in late 2025, says wagering requirements attached to incentives must not exceed 10 times the incentive amount. The start date was initially set for 19 December 2025, but the regulator pushed it back by one month, to 19 January 2026 – a delay later summarised as a short implementation window for operators. The obligation applies to all licence types except gaming machine technical and software licences.

Before the change, it was not unusual for a bonus to come with a 20x or30x playthrough demand, and some went far higher. The regulator did not publish a league table of old multiples, but the 10x ceiling is a sharp cut. What it means in practice is that any incentive – a matched deposit, a cashback deal, a free-bet token – that ties withdrawable funds to a turnover hurdle above ten times the bonus value is now a compliance matter, not a commercial decision.

The End of ‘Bet £5, Get 20 Free Spins’

The second big change outlaws a promotional staple: the mixed-product incentive. The Gambling Commission now forbids offers “designed on the basis that a consumer plays different gambling products,” as it wrote in a December blog post setting out the rules. The Commission’s own example is as clear as it gets. “Bet £5 and get 20 free spins” is prohibited because it attaches a sports-bet trigger to a casino reward. By contrast, “Bet £5 and get a £10 free bet” does not mix product types and stays lawful.

The logic is to stop gamblers being nudged from one product type to another in a single step. A sports punter who is handed free spins is being led to slots; a slots player who gets a free bet is being tipped into the sports book. The Commission’s stated aim, repeated in the same blog, is to make promotional offers safer and simpler. The mixed-product ban lands on the same19 January date as the cap and applies across all relevant licences.

What the Cap Doesn’t Cover

The 10x ceiling is a rule about how many times bonus cash must be cycled before a withdrawal, not about what runs alongside it. Operators still attach minimum odds requirements, expiry windows and maximum-winnings caps to promotions, and nothing in the Commission’s rules stops them. The guidance does not give an exhaustive list of what else can lawfully be layered on, so a player reading a bonus terms page will still need to hunt for those.

Free bets on sports are a different creature. Unlike casino bonus funds, a free bet usually gives only the net winnings; the stake amount is not returned. The Commission’s 10x rule applies to wagering on the bonus value, not to the stake-on-return mechanism, but the practical effect on a free bet is tilted because the outlay the player makes upfront changes the maths. A £10 free bet that requires a 10x turnover on the bonus amount still means £100 in qualifying stakes, yet the player is also unable to reclaim the bet slip’s face value if the balance runs dry. The regulator by and large lets that machinery stand, and the word “free” on a sports promotion still needs a squint at the terms.

How to Read a Bonus After the Change

A bonus that reads “100% up to £50” and carries a 10x wagering requirement is, on the face of it, the most aggressive a UK-licensed site can now present. But it does not mean you keep the lot after turning over £500 of stakes. The house edge on the underlying game decides how much of the bankroll survives. If the wagering must be done on slots with a 4% house edge, you can expect to lose roughly £20 of expected value on the turnover alone – before a maximum-winnings cap might snatch the top off.

The shift from mixed-product offers to single-product ones is the most visible change on any landing page. An operator can still run a casino-only promotion and a sports-only promotion side by side, but it cannot bundle them into one banner. That forces the player to choose a lane before the first click, which, in theory, reduces the impulse to cross-sell. A quick check should confirm the offer says “casino” or “sports” and does not promise both, and that the small print shows a wagering multiple of10 or lower.

The rules that hit on19 January stripped out the heaviest bonus terms, but they didn’t convert bonus hunting into a riskless exercise. A player still needs to establish whether the offer is single-product, what the exact playthrough multiple is, how many days the clock runs, and whether a cap on winnings from bonus play takes the roof off. The Gambling Commission’s line is that it made incentives safer and simpler. On paper, that’s true. The operator’s terms-and-conditions link remains the one place where the full story gets told.
