The short answer
Yes in Great Britain, with a business licensed by the Gambling Commission and only if you are 18 or over. The Commission licenses and regulates the businesses that offer gambling in Great Britain, and its register lists 216 businesses with an active remote casino or betting licence on 18 October 2026.
A licence is required to offer gambling
Section 33 of the Gambling Act 2005 makes it an offence to provide facilities for gambling without the licence, permit or exception the Act requires. That is why the domain on the register matters: it is the operator’s declaration of where it offers gambling under its licence.
Minimum age: 18
Inviting, causing or permitting a child or young person to gamble is an offence under section 46 of the Gambling Act 2005. Online casino play and betting with a licensed operator are for adults aged 18 and over.
Stake limits on online slots
Since 9 April 2025 the maximum stake on an online slot is £5 per game cycle for adults aged 25 or over, and since 21 May 2025 it is £2 for adults aged 18 to 24. The limits apply to online slots only, not to roulette or blackjack (Gambling Commission guidance).
Bonus rules since 19 January 2026
Since 19 January 2026 licensed operators cannot attach wagering requirements of more than 10 times to a bonus, and promotions that make you play two or more types of gambling (for example betting and slots) to unlock them are banned (Gambling Commission).
Self-exclusion
Every online gambling operator licensed by the Gambling Commission has had to participate in GAMSTOP, the free online self-exclusion scheme, since 31 March 2020. How GAMSTOP works.
