Why do bonuses expire?

Why do bonuses expire? Four reasons behind the deadline

Every bonus has an expected cost to the casino. A deadline turns that cost into something the operator can count and close off. Without one, bonus balances and unused spins would sit on accounts for months or years, still owed in principle and still affecting the casino’s figures. The reasons usually come down to four points:

1. Budget control. A promotion is paid for from a marketing budget for a set period. Expiry stops the cost running on after that period ends.
2. Purpose. A welcome offer exists to introduce a new customer to the site. An offer used a year later no longer does that job.
3. Record-keeping. Unused promotional balances need tracking. A cut-off date lets the casino clear them in an orderly way.
4. Clear rules for everyone. A fixed window means each customer gets the same deal, which makes the terms simpler to state and enforce.

None of those reasons are hidden. UK advertising guidance treats time limits to claim or use an offer as a significant condition that must be shown prominently. This page is part of our casino bonus questions section, and our broader guide to bonus expiry collects the time limits on UK welcome offers.

The three bonus expiry clocks and how they differ

People often talk about a bonus ‘expiring’ as if there were one deadline. In most terms there are up to three, and each one ends something different.

The glossary entries on the claim window and the validity period explain the two most common clocks, and free spins expiry looks at spin offers specifically. PlayOJO’s help page says free spins expire after 24 hours and that the Rewards section shows each spin’s game, value and deadline, so check that section as soon as the spins appear.

What you lose when a casino bonus expires

When a deadline passes, the casino removes whatever is still promotional. That usually means unused free spins, the remaining bonus balance and any winnings still locked to the bonus. What it can’t take is your deposit balance. Gambling Commission guidance on un-staked deposits (opens in a new tab) says deposited money remains the customer’s property, and separate guidance stops operators confiscating deposit-balance funds just because an account goes quiet.

With no-wagering offers, any winnings from spins you have already played are normally paid as cash straight away, so the deadline only removes spins you haven’t used. That’s a key difference from a match bonus, where an unfinished wagering requirement can wipe out bonus winnings built up over several days. Read what happens if I lose my bonus and why did my bonus disappear for the common scenarios.

Bonus expiry in pounds: what a deadline means per day

A wagering deadline is easier to judge when you divide the total by the days available. These figures use our partners’ published terms and show the average amount you would need to stake each day to finish in time.

At 50p a spin, £83 a day is about 166 spins every day for three days. At a typical 96% RTP, the average cost of £250 of wagering is about £10, though any run of spins can differ a great deal. If that pace doesn’t suit the time or money you planned to spend, a smaller bonus or no bonus at all is the sensible choice. The wagering calculator does the sums for any amount, and how to calculate wagering requirements shows the method.

A deadline should never set the pace of your play. If you notice yourself speeding up to beat the clock, that is a good moment to stop and let the bonus lapse.

Daily spin offers: why each batch has its own expiry

Ladbrokes spreads its welcome spins across ten days: 50 free spins a day after a £10 slots spend, up to 500 in total, each claimed before 23:59 that day and valid for 7 days. Missing a day means that day’s 50 spins (£5 of value at 10p) are gone; the rest of the run isn’t affected. The daily structure is a deliberate design choice that spreads the cost over time. Our comparison of daily free spins vs one-off free spins weighs the two formats, and Ladbrokes bonus expiry covers that offer’s dates.

UK rules on bonus deadlines and time limits

No UK rule sets a minimum or maximum time for a bonus to last. The rules focus on how time limits are communicated and how they interact with other terms:

• Time limits are significant conditions. The ASA’s guidance on free bets and bonuses (opens in a new tab) lists time limits to claim or use an offer among the conditions that must be stated clearly and prominently.
• Terms must be available for the whole promotion. The Commission’s marketing code 5.1.9 (opens in a new tab) requires each incentive’s terms to stay available for its full duration.
• No bigger reward for qualifying faster. A casino can’t alter or increase an incentive because you reach the qualifying spend sooner than the full offer period. That is separate from an ordinary expiry date.
• Wagering is capped at 10x. A short deadline can’t be paired with heavy wagering any more, because the 10x wagering cap applies to every UK casino bonus.

If a deadline wasn’t shown clearly before you opted in, the term may be open to challenge. See how to spot unfair bonus terms and the time-based incentive rules for the detail.

Do bonus deadlines push people to gamble more?

They can. A ticking clock creates pressure, and pressure is a poor guide to spending. Several UK rules already pull against that: offers can’t be increased because you qualify sooner, operators must stop new bonuses for customers showing strong signs of harm, and every new customer is prompted to set a financial limit before their first deposit (since 31 October 2025). Our guide to bonuses and gambling harm and the page on when to say no to a bonus explain the warning signs.

Bonus expiry myths and facts

How to keep track of a bonus before it expires

1. Before you opt in, write down each clock: claim window, validity period and any wagering deadline.
2. Check the times are in UK time and note whether a day ends at 23:59 or after a set number of hours.
3. After the qualifying bet or deposit, open the bonus or rewards area to confirm the spins or funds have arrived.
4. Use spins or bonus funds only during sessions you had already planned, within your limits.
5. Watch the wagering progress bar if the offer has wagering, and decide early whether to continue or opt out.
6. If spins or funds don’t appear in time, contact support straight away and keep a record.

Bonuses with the clearest deadlines: our partners compared

Every partner offer has a time limit; the difference is how much depends on it. With no wagering, a deadline only affects spins you haven’t used yet. All three offers below are for new customers aged 18+, and terms apply.

• Coral: deposit (some payment types excluded) and bet £10 on slots for 100 free spins at 10p (£10 of spins) on selected games. Accept within 48 hours and use within 7 days; spin winnings carry no wagering. The offer runs from 1 October 2026 to 1 February 2027. See Coral bonus expiry.
• Ladbrokes: deposit and spend £10 on slots for 50 free spins a day for 10 days (up to 500 spins, up to £50 at 10p). Claim each batch before 23:59 that day; spins are valid for 7 days on selected games, with no wagering. Prepaid cards, PayPal, Paysafe, Neteller, Skrill and Moneybookers deposits don’t qualify.
• PlayOJO: 80 free spins on Big Bass Bonanza at 10p (£8 of spins) on a first deposit of £10 or more, with winnings paid in cash. UK customers excluding Northern Ireland, via the designated link only. PlayOJO’s help page says free spins expire after 24 hours; see PlayOJO bonus expiry.

Coral’s single 7-day batch is the simplest to track. Ladbrokes gives more spins but asks you to claim on ten separate days. Whichever you choose, gambling costs money and losses are the likely result over time.
