Common Questions
Everything you need to know about playing safely at UK online casinos.
Yes. Online gambling is fully legal in the UK for players aged 18 and over. All licensed operators must hold a valid licence from the UK Gambling Commission (UKGC). Thames Fortune only features UKGC-licensed casinos.
Look for a UKGC licence number (displayed in the footer of reputable casinos), SSL encryption, and responsible gambling tools like deposit limits and self-exclusion. All casinos on Thames Fortune have been manually verified.
No. Since April 2020, the UK Gambling Commission banned the use of credit cards for online gambling. You can use debit cards (Visa, Mastercard), e-wallets (PayPal, Skrill, Neteller), prepaid cards, or bank transfers.
A wagering requirement specifies how many times you must bet the bonus amount before you can withdraw winnings. For example, a 30x wagering requirement on a £100 bonus means you must place £3,000 in bets. We highlight bonuses with lower, fairer wagering requirements.
E-wallets (PayPal, Skrill) are typically fastest at 0–24 hours. Debit cards usually take 1–3 business days. Bank transfers can take 3–5 business days. We clearly mark casinos offering same-day withdrawals.
GamStop is a free UK national self-exclusion scheme. When you sign up, all UKGC-licensed casinos must block your account for a minimum of 6 months (up to 5 years). Visit gamstop.co.uk to enrol.
Free spins are bonus rounds awarded on specific slot games — often part of a welcome bonus. Winnings from free spins are usually subject to wagering requirements. Always check which games qualify and the expiry date.
No. Thames Fortune is an independent casino comparison and affiliate marketing website. We do not operate any casino, accept bets, or hold any gambling licence. Our purpose is to help UK players compare licensed online casinos.
