New UK Casino Sites and Their Welcome Bonuses

offers.bet has picked out the newest casino sites in the UK on our list of 31 partner casinos and checked their welcome bonuses, licence details and significant terms. New UK online casinos arrive every month, and almost all of them lead with a welcome offer. Many, though, are not as new as they look. A fresh logo can sit on a licence that has been running for a decade, and a brand can be “new” simply because it has moved to a different platform.
So we split the field in two. Two casinos launched or relaunched in 2026, which we confirmed from the operator’s own announcement and the UK Gambling Commission register. The other five are the youngest brands on our list, all of which arrived from 2019 onwards, with the date we could confirm for each.
New UK Casino Sites: 2026 Launches and Recent Arrivals
BetSuna and Megaways Casino lead the list as this year’s launches. Spin King, Mr Vegas, Happy Tiger, LiveScore Casino and Virgin Bet follow as the newer brands that have joined the UK market since 2019.

BetSuna is the youngest casino on our list. ProgressPlay launched it in May 2026 as a combined casino, sportsbook and bingo site, and its own About Us page says it was founded this year. As a white label on ProgressPlay’s licence (account 39335) it starts life with an established cashier and a live lobby from Evolution and Playtech of more than 100 tables. The opening match up to £100 with 50 spins sits at the new 10x ceiling, and winnings convert up to one times the bonus.
Megaways Casino

Megaways Casino is new in a different sense. Gamesys opened it with Big Time Gaming in 2021; in March 2026 SkillOnNet relaunched it on its own platform with a fresh identity, so anyone joining now opens a new account under Skill On Net’s licence (account 39326). The relaunched lobby runs to more than 8,000 games, heavy on the Megaways mechanic, and the welcome deal is 100 spins at 10p on Fishin’ Frenzy The Big Catch Megaways for a £10 bet.
Spin King
100% up to £100 bonus
Promo Code: Added automatically at sign-up
New GB customers only. One offer across sites on the same licence. Opt in at sign-up and make a deposit of min. £20 within 31 days. Bonus = 1 x deposit up to max. £100. Wager both deposit and bonus together 10x (if wagered solely on selected slots) or the equivalent of 5x (if wagered solely on bingo) or a combination of these amounts within 30 days before withdrawing winnings. Withdrawing deposit or deposit winnings before completing wagering will void the bonus and any bonus winnings. Max bonus wins = £300 (exceptions as set out in full bonus terms). 18+ GambleAware.org
Spin King is the second brand from Happytiger ApS, the Aalborg company that took out its own UK casino and bingo licence in July 2021, and its iPhone app is a recent App Store release with only a few ratings so far. The lobby leans on progressive jackpots and a new-games section. Its welcome match up to £100 can be cleared on slots or bingo, but it is shared with Happy Tiger: claim at one and the other is closed to you.
Mr Vegas

Promo Code: Entered automatically at registration
New players only. Min dep £10. Wager req. 10x. T&Cs apply. 18+ GambleAware.org
