Can I change my bonus?

Can I change my bonus once I’ve claimed it?

In most cases, no. A casino bonus is an agreement made at the moment you opt in, deposit or place the qualifying bet, and its main terms are set from then on. You can’t normally switch to a different welcome offer, raise the amount, move free spins to another slot or shorten the wagering. You can, however, walk away from it: every UK-licensed casino must let you withdraw your own deposit balance, and most let you cancel a casino bonus from your account or through support.

The fixed-terms rule works in your favour too. The Gambling Commission’s guidance on the right to vary a promotion (opens in a new tab) says operators must not change or withdraw a promotion for a customer who has opted in, except to prevent fraud or similar unlawful behaviour. Neither side gets to rewrite the deal halfway through. More short answers on everyday bonus problems are collected in our casino bonus questions section.

18+ only. Every offer on this page has full terms; read them before you opt in, because that is the last point at which you can choose freely.

What you can and can’t change about a casino bonus

Here is how the main parts of a bonus usually behave once it has been claimed at a UK-licensed casino. The detail always depends on the terms of the specific offer.

Two of those rows have their own pages: whether you can choose the slot for your free spins and what stake free spins are played at.

Changing your mind before you claim a bonus

Up to the moment you claim, you are free to choose. Signing up for an account doesn’t commit you to any particular promotion, and many offers need a separate opt-in. That is the stage to compare offers, check the excluded payment methods and decide whether you want a bonus at all. The comparison is worked through in how to choose a welcome bonus.

1. Read the significant terms shown next to the offer: deposit, qualifying bet, spin value, wagering and deadlines.
2. Check that your payment method qualifies; e-wallets and prepaid cards are excluded from several welcome offers.
3. Decide which offer you want before signing up, especially where you must pick at registration.
4. Opt in or use the designated offer link exactly as the terms say.
5. Make the qualifying deposit or bet only once you’re sure, because that is usually the point of no return.

Changing between a sports and a casino welcome bonus

A common reason people ask whether they can change their bonus is that they picked the wrong product at sign-up. Since 19 January 2026, Commission rules ban promotions that mix gambling products, so a casino bonus can’t be earned through sports bets and a free bet can’t come from slot play. Brands that run both a sportsbook and a casino now make you choose one welcome offer for one product. See sports or casino welcome offer and the mixed-product promotion ban for the details.

10bet’s offer terms are a clear example: new UK customers choose the casino welcome bonus at sign-up. If you pick the sports option by mistake, contact support before depositing; once the first deposit is made under one offer, the terms decide whether a switch is possible, and you shouldn’t assume it is. Coral’s and Ladbrokes’ casino offers both need a qualifying bet on slots, and PlayOJO is casino-only, so the sports-or-casino question doesn’t arise there in the same way.

Can I change my bonus amount after depositing?

Not by depositing again. Deposit match bonuses are worked out on the qualifying deposit, usually the first deposit, at the moment it is made. Topping up afterwards adds cash to your balance but doesn’t recalculate the bonus. The table shows how each partner offer is fixed by what you do at the start.

If you deposited £20 at Casumo and wish you had deposited £200 for the £100 maximum, that bonus can’t be enlarged afterwards. It’s also worth remembering that a bigger match brings a bigger target: £100 at 10x is £1,000 of wagering, which at a 4% house edge costs about £40 on average. Our page on the 50% deposit bonus runs those numbers.

Cancelling one bonus to take another

Where you have a choice of promotions as an existing customer, you can usually cancel the active one and opt into another later, if you’re eligible. What you can’t do is carry anything across: cancelling removes the bonus balance and any winnings tied to it, and the new offer starts with its own terms. Some casinos also hold several promotions in a bonus queue and activate them one at a time, so the bonus you see first may not be the one you wanted to use first.

Welcome offers are different. They are for new customers only and normally once per person, household or payment method, so cancelling a welcome bonus doesn’t free you to claim a different welcome offer at the same casino. Our answer on claiming two welcome bonuses explains the limits, and should I opt out of a bonus? helps with the decision.

Can the casino change my bonus instead?

Not once you have opted in. Commission guidance treats terms that let a casino vary or withdraw a live promotion as unfair, and the only exception is preventing fraud or similar unlawful behaviour. Licence condition 7.1.1 also requires material changes to general terms to be notified before they take effect. A casino can end an offer for new sign-ups, as Coral’s terms do on 1 February 2027, but that doesn’t affect spins already issued under the old terms.

There is one important exception that isn’t a change of terms: operators must stop marketing and new bonuses to customers showing strong signs of gambling harm. That is a safeguard, not a penalty, and our page on bonuses and harm indicators explains it. For what to do if terms seem to have shifted, see what happens if a casino changes bonus terms.

Fixing a bonus mistake: wrong method, missed opt-in, wrong offer

Most requests to change a bonus are really requests to fix a mistake. The common ones are depositing with an excluded payment method, forgetting to opt in, or using the wrong link. Support teams can sometimes help, but they apply the published terms and there is no right to a fix. Coral’s and Ladbrokes’ offers exclude PayPal, Neteller, Skrill, Paysafe and prepaid cards, along with certain debit cards at Coral; 10bet excludes Skrill and Neteller. Our guide to how payment exclusions work covers why.

1. Stop before playing further, so the position is easy to explain.
2. Screenshot the offer page, your deposit record and your bonus area.
3. Contact support, say exactly what happened and ask whether the bonus can be applied or the deposit treated differently.
4. Accept that the answer may be no if the terms were shown clearly at the time.
5. If you think a significant term was hidden, use the formal complaints process.

Changing casino: Coral, Ladbrokes and sister sites

Some people ask whether they can swap one brand’s welcome offer for a sister brand’s. Coral and Ladbrokes are both run by LC International Limited (part of Entain, UKGC account 54743), and operators often treat brands on the same licence as linked for welcome offers. One person may not be able to hold new-customer status at both, so check both sets of terms before signing up. See sister-site bonus rules and do Coral and Ladbrokes share accounts?.

Opening a second account at the same casino to get a different offer is not a way round this. Terms ban multiple accounts, and breaking that rule can void winnings from both.

UK rules that fix bonus terms in place

Several UK rules explain why bonuses are locked once claimed, and why that lock binds the casino as much as you. The Commission’s news on safer and simpler promotions (opens in a new tab) summarises the 2026 changes.

• 10x wagering cap (19 January 2026): no bonus can require wagering of more than 10 times the bonus under code 5.1.1 (opens in a new tab).
• No mixed-product offers (19 January 2026): you choose a casino or a sports offer, not a blend.
• No bigger reward for qualifying faster: an incentive can’t be altered or increased because you hit the qualifying spend sooner.
• No varying after opt-in: set out in Commission guidance based on the CMA’s 2018 work.
• Opt-in, not automatic enrolment: you must choose to join a promotion.

Our timeline of bonus rules places each change in order.

Partner offers: what is fixed once you claim

Each partner offer below is for UK adults aged 18+, and full terms apply. Because none of them can be changed after claiming, read the key terms first.

• Coral: deposit (certain types excluded) and bet £10 or more on slots to get 100 free spins at 10p each on selected games. Accept within 48 hours, use within 7 days; no wagering on spin winnings. Runs 1 October 2026 to 1 February 2027. Full detail in the Coral bonus terms.
• Ladbrokes: deposit and spend £10 or more on slots to get 50 free spins a day for the first 10 days (up to 500), 10p each on selected games. Claim before 23:59 each day; spins last 7 days; no wagering. Prepaid cards, PayPal, Paysafe, Neteller, Skrill and Moneybookers deposits don’t qualify.
• PlayOJO: first deposit of £10 or more through the designated offer link brings 80 spins at 10p on Big Bass Bonanza, winnings paid in cash with no wagering. New UK customers only, excluding Northern Ireland, and it can’t be combined with other offers.

Because the Coral and Ladbrokes brands share an operator, check whether you can claim at both before choosing.
