A bonus is not free money. It’s a marketing offer with conditions attached, and the conditions are where the value sits — or doesn’t.
The good news for UK players is that this area changed substantially in early 2026, and the terms you’ll now see at licensed sites are simpler and less punishing than the ones that were standard a few years ago. The bad news is that the details still matter, and a bonus can still cost you more than it’s worth.

What changed in 2026
Two rules now apply to every Gambling Commission-licensed operator, introduced under an amendment to the LCCP social responsibility code and taking effect in January 2026:
1. Wagering requirements are capped at 10x. Operators cannot require you to play through bonus funds more than ten times. Before this, 30x, 40x and occasionally 60x or higher were routine, and the Commission concluded that high multiples confused players and encouraged longer, faster and larger play.
2. Mixed-product promotions are banned. A single offer can no longer require you to use more than one type of gambling product. The “bet £10 on football, get 50 free spins” style of promotion is gone, on the basis that players are at greater risk when moving across multiple products and that combined terms were hard to follow.
If you encounter a UK-facing site advertising 35x wagering today, that’s a signal about the site — most likely that it isn’t UK-licensed.
The cap is a real improvement. It does not make bonuses free, and it doesn’t touch the other clauses covered below.
How wagering requirements work
A wagering requirement (also called playthrough, or a rollover) is the total amount you must stake before bonus funds and anything won from them can be withdrawn.
Worked example. You deposit £50 and receive a £50 bonus with 10x wagering applied to the bonus.
- Requirement: £50 × 10 = £500 of total stakes
- At £1 per spin, that’s 500 spins
- On a game returning 96%, you’d expect to lose roughly £20 across that turnover on average
You are not required to win £500. You’re required to stake £500 in total, and the same money recycles: a £1 stake that returns £0.90 gives you £0.90 to stake again, each turn counting toward the total.
The critical detail is what the multiple applies to.
| Basis | Requirement on a £50 + £50 offer |
|---|---|
| Bonus only (10x) | £500 |
| Deposit + bonus (10x) | £1,000 |
Same headline multiple, double the work. “Bonus only” is significantly better and worth checking every time.
Game weighting
Not every game counts equally toward the requirement. A typical weighting table:
| Game type | Contribution |
|---|---|
| Slots (most) | 100% |
| Some high-RTP or jackpot slots | 20% or excluded |
| Roulette | 10–20%, sometimes excluded |
| Blackjack | 5–10%, sometimes excluded |
| Video poker | 5–10% |
| Live dealer games | Often excluded entirely |
The logic is house edge. Slots carry a larger edge, so operators are happy for them to count fully. Blackjack played well has a very small edge, so it either counts for a fraction or not at all.
What this means in practice. With a £500 requirement and blackjack contributing 10%, you’d need to stake £5,000 at the tables to clear the same bonus. If you’re primarily a table games or live casino player, most slots-oriented bonuses are worth considerably less to you than the headline suggests — and sometimes worth nothing at all.
Always check the weighting table before opting in, not after.
Maximum bet while wagering
Nearly every bonus caps your stake per spin or hand while a wagering requirement is active — commonly £5, sometimes £2, and occasionally a percentage of the bonus.
Breach it, even once and even accidentally, and the standard consequence is forfeiture of the bonus and everything won with it. This is the single most common reason players lose bonus winnings, and it usually happens by accident: a bet size carried over from a previous session, a feature buy, or a change of game without checking.
The clause is enforceable and operators do enforce it. Set your stake deliberately at the start of a bonus session and leave it alone.
Note that separate statutory limits also apply regardless of bonuses: £5 per game cycle on online slots for players aged 25 and over, and £2 for players aged 18 to 24.
Maximum conversion and win caps
Many bonuses limit how much of your bonus winnings you can actually withdraw — often expressed as a multiple of the bonus, such as 4x or 5x, or as a flat figure.
Example. £20 free spins bonus, max conversion 4x. You hit a £900 win on the spins. You clear the wagering. You withdraw £80. The rest is removed.
This is legal and disclosed, but it’s the term most likely to produce a genuinely unpleasant surprise, and it’s worth finding before you play rather than after. Free spins offers with no deposit almost always carry a tight conversion cap — that’s the trade-off for the offer costing you nothing.
Expiry
Bonus funds and free spins expire. Typical windows are 7 to 30 days for wagering, and 24 hours to 7 days for free spins to be used.
Expiry is what turns a manageable requirement into a pressured one. A £500 requirement over 30 days is a relaxed pace; the same requirement over 3 days is an invitation to play faster and larger than you meant to. If the timeframe means you’d have to change how you’d normally play, the offer isn’t a good fit — that’s a sound reason to decline it.
Common bonus types
Welcome / deposit match. The standard: deposit £50, get £50 in bonus funds. Largest headline value, full wagering.
Free spins. A set number of spins on named games, usually at a fixed low stake value. Winnings are typically credited as bonus funds subject to wagering, and usually with a conversion cap. The spin’s stake value is the number that determines what they’re actually worth — 50 spins at £0.10 is £5 of play, not a windfall.
No-deposit bonus. A small amount of bonus funds or spins for registering. Genuinely costs nothing, and correspondingly comes with tight caps. Useful for trying a site, not for winning at one.
Cashback. A percentage of net losses returned over a period. Sometimes paid as cash with no wagering, which makes it one of the more straightforward offers — but check, because cashback credited as bonus funds is a different thing.
Reload offers. Smaller ongoing deposit matches for existing customers.
Loyalty and VIP schemes. Points accrued through play, exchanged for bonuses or perks. Worth reading with a clear head: schemes that reward higher spend with better treatment can quietly encourage exactly the behaviour you’d want to avoid. If a VIP host contacts you personally after a losing run, treat that as a warning rather than a compliment.
Working out whether a bonus is worth taking
A rough method, using expected cost of clearing:
Turnover required × house edge of the games you’ll play = expected cost
Take a £50 bonus at 10x on bonus only, cleared on slots at 96% RTP (a 4% edge):
- Turnover: £500
- Expected cost: £500 × 0.04 = £20
- Bonus value: £50
- Expected net: +£30 before any win cap
On that arithmetic the offer is positive in expectation. Now apply a 4x conversion cap and the picture changes for the outcomes that matter most — big wins get truncated while losses don’t. Add a heavy weighting penalty and it can go negative entirely.
Two important caveats. First, this is an average across many repetitions; your single session is dominated by variance, and the most likely individual outcome is still losing your deposit. Second, and more importantly: a bonus obliges you to keep playing. If a £500 turnover requirement makes you play longer than you would have chosen to, the bonus has cost you something the arithmetic doesn’t capture.
It is always fine to decline a bonus. Playing with your own money, withdrawable whenever you like, is the simplest way to use a casino and often the better one.
Terms worth checking before you opt in
- Wagering multiple, and whether it applies to bonus only or deposit plus bonus
- Game weighting table and excluded titles
- Maximum bet while wagering
- Maximum conversion or win cap
- Expiry on both bonus and spins
- Excluded payment methods — many offers exclude certain e-wallets, and this is often disclosed only in the full terms
- Whether declining the bonus is possible after depositing, and how
- Any minimum deposit or minimum odds conditions
If you can’t find these in under five minutes, that itself tells you something about the operator.
Frequently asked questions
Can I withdraw a bonus without wagering it? No. Bonus funds are non-withdrawable until the requirement is met. Most sites will let you forfeit the bonus and withdraw your own remaining deposit, though doing so usually removes any winnings attributed to bonus play.
What happens if I request a withdrawal mid-wagering? Typically the bonus and associated winnings are voided and you receive your remaining real-money balance. Check the specific term — implementations vary.
Is 10x wagering good? Compared with the 30x–40x that was standard before 2026, yes, considerably. But the multiple is only one of five or six terms that determine value. A 10x bonus with a 4x conversion cap and heavy weighting exclusions can be worth less than a plainly structured offer.
Are no-wagering bonuses real? Yes, some operators offer spins or cashback with no wagering attached. They’re usually smaller, and worth more per pound than a headline offer with conditions.
Why can’t I get a bonus that combines sports and casino any more? UK rules now prohibit promotions requiring more than one type of gambling product, on evidence that multi-product play increases risk of harm and that combined terms confused customers.
Can an operator take my winnings for “bonus abuse”? Terms typically allow forfeiture for breaching bonus conditions — most often the max bet rule. If you believe a decision was wrong, complain to the operator in writing and escalate free of charge to their ADR provider if it isn’t resolved.
