Casumo customer service for UK players is reached by email at hey@casumo.com, and Casumo lists its UK support hours as 7:00 to 23:00 (GMT/BST). Messages sent outside those hours wait until the morning. For a formal complaint, follow the procedure in Casumo’s terms; if it isn’t resolved within eight weeks, UK rules let you take it to a free independent dispute service.
Casumo’s published UK contact is hey@casumo.com, with support hours of 7:00–23:00 UK time.
That’s 16 staffed hours a day; plan anything time-sensitive, such as bonus deadlines, around them.
Many answers, from minimum deposits to withdrawal times by method, are already published on Casumo’s site.
Complaints should be resolved within eight weeks under UK rules, then can go to the free ADR provider named in Casumo’s terms.

Casumo customer service contacts and hours
Casumo publishes one contact route on its public UK pages: email to hey@casumo.com. The same pages give UK support hours of 7:00 AM to 11:00 PM, GMT or BST depending on the time of year. Phone and live chat details aren’t stated on the public pages our research could read, so the table separates what’s confirmed from what you should check in your account.

Working with Casumo’s 7:00–23:00 support hours
Seven in the morning to eleven at night is 16 hours a day, or 112 hours a week. That covers most people’s waking hours, but it does leave an overnight gap. If something goes wrong at 23:30, the realistic expectation is a reply after 7:00 the next morning.
That matters most when a deadline is running. Casumo’s welcome bonus has a 7-day wagering window, and its withdrawal policy says a withdrawal should be approved or denied within 3 days. Raising a question early in the day, rather than late at night, gives support the most time to act within those windows.

Is there Casumo live chat?
Casumo’s public UK pages that our research could read list email and support hours but don’t describe live chat, and we haven’t been able to confirm chat from an official source. If live chat is offered, it would normally appear in the help area once you’re logged in on the website or in the Casumo app. If you can’t find it, email works within the same support hours. Logging-in problems are covered on our Casumo login page, and the Casumo app page describes the app itself.
Answers Casumo already publishes
Before emailing, it’s worth knowing which questions Casumo has already answered on its own pages. These are the ones slot players ask about most.

Some questions need someone to look at your account. These come up regularly for slot players at Casumo.
Bonus progress: how much of the 10x wagering is left and when the 7-day window ends.
Bet limits: whether a stake over £5 while a bonus was active affected it; the terms cap bets at £5 with an active bonus.
Game restrictions: whether a particular slot counts towards wagering, since game restrictions apply to the bonus.
Frozen or disputed spins: what the round record shows; our guide to a slot freezing mid-spin explains how these are settled.
Pending withdrawals: whether verification or an extra check above the €1,000 equivalent is holding it.
For game disputes, the round history is the key evidence. Our guide to checking your slot game history shows what it contains and how to quote a round.
Making a complaint to Casumo
Every UK-licensed operator must publish a complaints procedure, and Casumo’s is in the terms and conditions linked from its site footer. Read the complaints section before escalating, because it may ask for a particular format or contact. The general shape of a UK complaint looks like this.
Raise the issue with Casumo support by email and allow time for a reply within support hours.
If the answer doesn’t resolve it, state clearly in writing that you are making a formal complaint.
Follow any specific steps in the complaints section of Casumo’s terms.
Keep copies of every email, with dates.
Under Gambling Commission rules, expect a final response within eight weeks of the complaint being received.
If it isn’t resolved, take it to the alternative dispute resolution (ADR) provider Casumo names.
Independent dispute resolution for Casumo customers
ADR is a free, independent review once an operator’s own process has finished. The Gambling Commission approves ADR providers and requires every licensed operator to name one. The reviewer decides whether the operator applied its terms fairly; it doesn’t replace terms with more generous ones.
Casumo’s ADR provider wasn’t named on the public pages our research could access, so look for it in the complaints section of the terms or in Casumo’s final response to your complaint. Coral and Ladbrokes, for comparison, name IBAS, which allows 12 months to refer and makes rulings binding on the operator up to £10,000. Check the deadline for whichever provider Casumo names as soon as you have its final answer.
Checking Casumo with the Gambling Commission
The Gambling Commission doesn’t settle individual disputes, but its public register shows who holds a licence and any regulatory action. Casumo’s operator, Recro Limited, holds remote casino licence account 61549, active since 21 December 2023. Our guide to checking a slot site’s licence shows how to look it up, and is Casumo legit goes into more detail.
Help with your gambling outside Casumo’s support hours
Casumo’s Play Okay section explains its safer gambling tools, and its site links to GamCare and GAMSTOP. Independent help doesn’t keep office hours: the National Gambling Helpline is free on 0808 8020 133, 24 hours a day, and GAMSTOP registration blocks every UK-licensed online operator at once. Our Casumo safer gambling page covers the tools, and gambling support in the UK lists every service.
Casumo’s welcome bonus and support questions about it
New Casumo customers aged 18+ who opt in can claim a 50% bonus up to £100 on their first deposit, with a minimum deposit of £20.

Frequently asked questions
How do I contact Casumo customer service?
Email hey@casumo.com. That’s the contact address Casumo publishes on its UK pages, alongside support hours of 7:00 to 23:00 UK time. Casumo’s public pages don’t list a phone number, and live chat isn’t described there, so check the help area once you’re logged in for any additional options. Write from your registered email and include your username, dates and amounts so the first reply can resolve things. Our Casumo review covers the wider site, and Casumo verification explains the identity checks that generate many support questions.
What are Casumo’s customer service hours?
Casumo lists its UK support hours as 7:00 AM to 11:00 PM, GMT or BST depending on the season. That’s 16 hours a day. A message sent after 23:00 will usually be picked up after 7:00 the next morning, so raise time-sensitive questions, such as a bonus close to its 7-day deadline, earlier in the day. For help with your gambling outside those hours, the National Gambling Helpline on 0808 8020 133 is free and open 24/7. Our Casumo safer gambling page and gambling support guide list other services.
Does Casumo have live chat?
Casumo’s public UK pages that our research could read list email at hey@casumo.com and support hours, but don’t describe live chat, so we can’t confirm it from an official source. If chat is available, look for it in the help area once you’re logged in on the website or app. Email works within the same 7:00 to 23:00 hours and gives you a written record, which is useful if a question later becomes a complaint. If you can’t log in, our Casumo login page covers the common fixes, and the Casumo app page explains the app.
Can I phone Casumo?
Casumo doesn’t publish a customer service phone number on the UK pages our research covered; the published route is email to hey@casumo.com during 7:00 to 23:00 UK time. If being able to call matters to you, compare sites before signing up. 10bet lists a UK freephone number with daily hours, and Ladbrokes’ terms mention telephone support. Our Casumo vs 10bet comparison puts the two side by side, and how to choose a slot site lists other things worth weighing up before you register.
How do I make a complaint to Casumo?
Start by emailing hey@casumo.com and giving support the chance to resolve it. If that doesn’t work, say clearly in writing that you are making a formal complaint, and follow any specific steps in the complaints section of Casumo’s terms and conditions. Under Gambling Commission rules, you should receive a final response within eight weeks. If you don’t, or you disagree with the outcome, you can refer the dispute to the free ADR provider Casumo names. Keep copies of everything. Our guide on how to complain to a slot site explains each stage.
Which ADR provider does Casumo use?
Casumo’s ADR provider wasn’t named on the public pages our research could access, so check the complaints section of its terms and conditions, or the final response to your complaint, which should tell you where to go next. Every UK-licensed operator must name a Gambling Commission-approved ADR provider, and using it is free. ADR reviews whether the operator applied its terms fairly. For comparison, Coral and Ladbrokes use IBAS. Our guides to complaining to a slot site and checking a slot site’s licence explain more.
Can Casumo support tell me how much bonus wagering I have left?
Yes, support can check your bonus progress if you can’t see it in your account. Casumo’s welcome bonus is 50% up to £100 on a first deposit of at least £20, must be wagered 10x within 7 days, and limits bets to £5 while it’s active. On a £50 deposit, for example, the £25 bonus means £250 of wagering. Game restrictions apply, so ask whether a particular slot counts. Our wagering requirement entry explains how wagering is counted, and how to track wagering shows how to keep your own tally.
Who do I contact about a pending Casumo withdrawal?
Email hey@casumo.com between 7:00 and 23:00 UK time with the date, amount and method of the withdrawal. Before you do, check Casumo’s published timings: its withdrawal policy says requests should be approved or denied within 3 days, and payouts above the equivalent of €1,000 may need extra verification. After approval, its homepage lists e-wallets and Apple Pay as instant, cards as up to 2 days and bank transfers as up to 5 days. Our Casumo withdrawal time page explains each stage, and Casumo verification covers the checks.
Gambling can be addictive. Free, confidential help is available 24 hours a day from the National Gambling Helpline on 0808 8020 133. Get support from GamCare or NHS gambling support, or block yourself from all UK-licensed gambling sites with GAMSTOP.
