iStock/Standard Jack Tanner 1 minute ago New online casinos go live in the UK on a regular basis and in 2026, we’ve seen several operators enter the market, including Betcrown, BetAhoy and Betnero.

The Standard reviews all new online casinos, analysing what they have to offer, whether they are a worthwhile addition to the market and weighing up whether they might one day challenge for a spot on our list of the best casino sites.

All our recommended new casino sites are licensed by the UK Gambling Commission and were launched in 2022 or later, which is our cutoff point for what qualifies as a new casino.

We’ve ranked our favourite new online casino sites for 2026. We will constantly monitor the rankings and update them regularly to reflect the changing landscape.

Pub Casino was one of the biggest launches for an online casino in several years with a strong marketing drive pushing the L&L Europe-backed platform into the public sphere.

It’s managed to remain a popular spot, particularly for slot players, who can choose from hundreds of online slots from all the top studios, including a handful of exclusive releases.

The Pub Casino welcome offer includes 50 no-wagering free spins worth 20p each on the slot game Octobeer Fortune when bettors deposit and wager £10.

Pub Casino hosts monthly tournaments with cash prizes up for grabs, while there’s a strong live casino offering with Evolution and Pragmatic Play powering the live roulette, blackjack, baccarat and game show offerings.

Unlike many new online casinos, Pub Casino also has a dedicated app available on both iOS and Android. The early reviews on iOS are relatively positive, but there are only a handful. In our experience, the app worked well, making it easy to switch between slot games and the live casino.

Rialto is owned by the team behind Grosvenor Casino, and as such, the established infrastructure and technology give this operator a massive leg up on fellow new casinos.

The welcome offer requires bettors to deposit and wager £10 to unlock 100 free spins, albeit the free spins are restricted to a spin-off of one of the best online slots brands, Big Bass, in Big Bass: Hold & Spinner. They also carry 10x wagering requirements and winnings are capped at £200.

Rialto carries live streams from Grosvenor’s land-based casino, so bettors can join in with the action taking place at one of their venues, while there are over 1,800 non-live games to choose from in the game library.

Rialto has some of the best offers among new online casinos, with free spins available daily and a loyalty scheme where bettors collect coins that can be exchanged for casino bonuses.
