21.co.uk

Overview

21.co.uk is a UK online casino running on the operating licence of LeoVegas Gaming PLC (UK Gambling Commission account 39198, active), part of the LeoVegas Group, which MGM Resorts International has owned since 2022. First things first: this is not the similarly named 21casino.com or 21.com — an unrelated operator — and much of what the wider web publishes about '21 Casino' conflates the two, inflating game and provider counts. The 21.co.uk domain itself is listed on the Commission's register, the site dates back to 2013, and it serves Great Britain only, in sterling. The pitch is a slots-heavy catalogue with a credible live-casino room, fee-free banking from a £10 floor and round-the-clock chat support, carried by one of the industry's biggest corporate parents.

Games and providers

The operator advertises a slots library of 2,000-plus titles, and the supplier list on our file runs to more than 30 studios: NetEnt, Microgaming, Playtech, Pragmatic Play, Play'n GO, Big Time Gaming, Red Tiger, Nolimit City, IGT, Evolution, Yggdrasil, Hacksaw Gaming, Relax Gaming, Blueprint Gaming and Push Gaming among them. Be aware that we could not independently verify a grand total, table-game or video-poker sub-counts, or demo-mode availability — the operator geo-restricts and bot-walls its own pages — and our data records roughly 30 live-dealer titles, which should likewise be treated as an estimate. Where we could not verify a number we say so rather than guess; the honest summary is a deep, provider-rich slots lobby with a functional live floor, whose exact dimensions you should confirm on the live site.

Bonuses and wagering

The current welcome offer is a 100% first-deposit match up to £50 plus £6 in live-casino chips, from a £10 minimum deposit, for new customers. One important honesty note: our verified record does not include the wagering multiplier for this offer — wagering requirements do apply, and the operator's own terms set the figure — so we will not quote a number we have not confirmed. Check the play-through, game weighting and expiry on the promotion page itself before opting in, and always read the full T&Cs. The £6 of live chips is a small but unusual sweetener for a UK welcome deal, worth noting if live roulette or blackjack is your main game.

Payments and withdrawal speed

Banking is a genuine strength. Deposits and withdrawals are fee-free with a £10 minimum on both, across Visa, Mastercard, PayPal, Apple Pay, Skrill, Neteller, Paysafecard and bank transfer. No standard pending hold is recorded on this account — cash-outs go straight to processing — and e-wallet and PayPal withdrawals often complete within hours, typically inside 24. The caveats: card withdrawals are slow at 2-5, and sometimes up to 2-7, working days; and you cannot withdraw to Paysafecard or Apple Pay, so deposits made those ways will return by another route. Sterling only, no cryptocurrency. Native apps on iOS (rated 4.3) and Android (rated 3.6) round out a solid everyday experience.

Trust and safety

The enforcement record is the heart of the trust question. In 2018 the licensee (then LeoVegas Gaming Limited) paid a £627,000 package over misleading advertising and self-exclusion failings — 41 misleading adverts, 11,205 self-excluded customers not refunded their balances, and 1,894 people marketed to after self-exclusion without opting back in. In 2022 came a £1.32 million fine for anti-money-laundering and safer-gambling failings between October 2019 and October 2020, with an official warning and a mandatory compliance audit — and the Commission's announcement explicitly named 21.co.uk among the affected brands. More recently, the group was fined €500,000 by the Dutch regulator in late 2025 for player-protection breaches, a decision under appeal. The licence is current and valid today; the failings are historical but real, and a depositing player deserves to know them.

Public sentiment is also poor: the player rating on file is 2.2 out of 5, though we have not verified the review volume behind it. Safer-gambling provision is complete — deposit, loss and wager limits, reality checks, time-outs, self-exclusion and GAMSTOP integration. The site is 18+ only, and free, confidential help is available at BeGambleAware.org.

Our verdict

We score 21.co.uk 6.2 out of 10. It is licensed and capable: a big-brand back end, fee-free £10 banking, fast e-wallet cash-outs, decent apps and 24/7 live chat. It is also a brand whose licensee has been penalised twice by its regulator — once in an action naming this very site — whose public reputation sits low, and whose catalogue figures partly resist independent verification. A reasonable home for slots and live-casino players who value support availability and clean banking; go in with eyes open on the compliance record, and confirm the bonus wagering and game counts on the live site before you commit.
