Best Online Casinos UK Licensed 2026: 5 Sites and Their Licence Details

For a player who puts licensing first, NetBet is the strongest choice in the UK: it displays Gambling Commission account 39170 with a direct link to the public register, names its operating company, and pairs that with the largest game library among the five sites below. Virgin Games and Casumo follow, each with a licence number on record from a third-party source.

Every online casino serving the UK must hold a Gambling Commission licence, but not every operator makes the details equally easy to find. For this shortlist, the bar was simple: a UK Gambling Commission account number on record for each site, so that a player can verify it in under a minute before depositing.

Only five brands in the wider UK pool met that bar. That does not mean the others are unlicensed; it means their numbers were not on record, and players should check those sites' footers themselves. The comparison below sets out what is known about each licence and what each casino offers, so the decision can rest on both. Where a detail comes from a review site rather than the operator, it is labelled, because the register, not a summary, is the final word.

Quick picks

• NetBet: licence number linked from its own site to the register
• Casumo: licence holder and number both named by a third party
• bet365: the biggest welcome spin count among the five

How We Evaluated These Casinos

The first test was verifiability, since a licence a player cannot check offers little reassurance: whether a licence number is on record, where it comes from, and whether the operator itself publishes it with a link to the register. Operator-published numbers ranked above those available only from third parties.

The second test was the commercial proposition behind the licence: the welcome offer, the game library, the ongoing rewards and the safer gambling tools. A licence establishes who regulates the casino; it does not, by itself, make an account worth opening.

The weighting reflects how players actually use these sites. A verified licence is the entry condition, and every site here meets it. Beyond that, the casino that gives a player the most to do, the clearest terms and the strongest tools for staying in control earns the higher place.

1. NetBet

NetBet treats its licence as part of the product rather than small print. The footer shows Gambling Commission account 39170, linked directly to the public register, and the operator is named as Netbet Enterprises Limited, established in 2006. The site also links to GamCare, GambleAware and IBAS, the independent adjudication service, and offers deposit, loss and bet limits, reality checks, session timers, time-outs, self-exclusion and GAMSTOP.

That disclosure is matched by the depth of the product. The lobby carries more than 5,500 games, over 5,000 of them slots, with NetBet exclusives such as NetBet Story of Odin and NetBet Bonanza, and RTP is displayed for every title.

The welcome is a £10 slot stake for 100 Big Bass Splash spins at 10p, with winnings paid as cash up to £100. Support runs 07:00 to 23:00 every day, and withdrawals typically take one to three business days.

For a player weighing licence quality against commercial value, NetBet removes the need to compromise. The licence is the easiest in this group to verify, and the account also provides access to the daily Wheel of Gold, offering a chance to win prizes with each spin, NetBet Max loyalty rewards with no wagering requirements on free spin winnings, and access to a sportsbook and poker room under the same brand. The main drawback is the welcome offer's spin count, which is lower than bet365's.

2. Virgin Games

Virgin Games' licence number, 38905, is cited by Racing Post and should be confirmed on the register; the current owner has not been captured.

The brand has operated since 2013 and centres on slots and bingo. Its welcome gives 70 spins at 10p on the Game of Thrones slot for a £10 slot wager, with an opt-in and a 30-day window, the longest among these five. For a casual player, that deadline matters more than the count.

Wagering on spin winnings is not confirmed, so the full terms should be read before claiming.

From a licensing perspective, Virgin Games offers a verifiable number but less surrounding disclosure: no named licence holder or support details are on record. A player should check the register entry and the site's help pages together before registering.

3. Casumo

Casumo's licence record is the most detailed after NetBet's. TNT Sports names the UK licence holder as Recro Limited, a Malta-based company, under account 61549, and notes that Casumo also holds licences in Malta, Gibraltar, Spain and Sweden. The UK licence previously sat with Casumo Services Limited.

The welcome is less settled: most sources describe a 50% match up to £100 at 10x, while BettingExpert lists a larger £150 package with 100 wager-free spins. The operator's own page should settle which applies.

For regulars, the daily Spinumo wheel and Valuables rewards are the main draw, and Casumo has accepted UK players since 2020.

The change of licence holder is worth knowing for anyone checking the register, since the current entry will show Recro Limited rather than the earlier company. Support is available by email at [email protected], according to Oddschecker.

4. 888casino

888casino, now part of the Evoke group, has UK licence 39028 cited by a third-party review site.

Its welcome is the only bonus-money offer among the five, and its terms are among the most fully stated: a 100% match up to £100, played through 10 times within five days on selected slots, with winnings capped at £100.

Racing Post reports more than 400 live dealer games, a clear strength for table players.

It is a long-running casino brand, previously part of 888 Holdings. Its licence number comes from a third-party source, so the register entry is the place to confirm it; the offer itself, running until the end of 2026, is clearly documented, with one claim per player and sterling accounts only.

5. bet365

The bet365 brand's account 55149 is cited by OLBG and should be confirmed on the register.

Commercially, it has the largest welcome among these five, up to 500 spins at 10p with no wagering on winnings, revealed over ten days after a £10 deposit. The spins work on selected games only.

The casino shares an account with bet365's sportsbook and poker room, which suits players who already bet there.

Existing customers can also play a free Daily Prize Matcher for spins, Golden Chips or cash. As with the other third-party numbers here, a quick check on the register closes the gap between what a review site reports and what the regulator holds.

Where the Licence Evidence Points

On licence transparency, NetBet leads clearly: an operator-published, register-linked account number, a named licence holder, links to GamCare, GambleAware and IBAS, and a full set of safer gambling tools, all backed by the largest library in this group. For players who want the most welcome spins from a licence-on-record brand, bet365 is the alternative. Whichever site is chosen, the same two steps apply: confirm the account number on the Gambling Commission's register, and set a deposit limit before claiming any welcome. UK rules also cap slot stakes at £2 per spin for players aged 18 to 24 and £5 for those aged 25 and over, and every licensed site must offer self-exclusion through GAMSTOP.
