Bet UK Sister Sites

The sportsbook on the file – read 13 August 2026

Bet UK sister sites are Slot Boss, BetMGM, 21.co.uk, LeoVegas and Pink Casino. Every one of them trades on UK Gambling Commission account 39198, which belongs to LeoVegas Gaming PLC, the Malta company holding all six brands as plain domain names – the account has never filed a trading name. The join route was checked on 13 August 2026 and the form came up straight away.

The five nearest names on account 39198, with the account file itself closing the set:

LeoVegas

Active for Great Britain – leovegas.co.uk

  • Keeps three entries on the domain list by itself, though only the .co.uk one is Active
  • Sells its welcome from a three-way offer menu before the form ever appears

The full account, from bingo to virtual betting

The betting permission on a casino licence

BetUK is the dedicated betting shopfront on an account that started life as a casino licence. The casino permission dates to 1 November 2014; betting on real events arrived on 29 April 2016, eighteen months later, and betting on virtual events followed as recently as 23 April 2025. BetUK trades on those betting permissions with a casino and live casino tucked behind the sportsbook, while BetMGM straddles both worlds and the other four stick to casino products. A bingo permission joined in February 2018 as well, though on this brand it shows nowhere – the bingo shelves live with the casino sisters. No premises are filed anywhere on the account, so the whole business runs online.

The register row for betuk.com

On the domain list, betuk.com is one of six Active entries, and it is the only one of the six filed as a bare .com without a www prefix on the register. A business register search for betuk turns up something none of the sister searches do: a second result. It is ibetuk.com, an iBet Global Limited domain sitting on account 53377 – one letter longer, different company, no connection. The five dormant entries behind the live six include the dot-com pair the flagship keeps and three bingo addresses that no longer answer at all. Searches for the other five brands each return account 39198 alone, and the full lookalike survey lives in the account file.

Forty pounds, in four pieces

The sports welcome read on 13 August 2026: bet £10 within seven days of joining and £40 in free bets follows, broken into four £10 tokens – two for football accumulators of four legs or more, two for sports multiples of two or more – each valid for seven days, with minimum odds attached and virtual sports, esports and non-British or Irish racing excluded. On the day it was read, the homepage banner carried no casino element beside it; the spin offers live with the casino sisters. Offers rotate, so the date matters.

The same form as five casinos

The Sign Up button opens the shared account machinery at /auth: first a menu of three welcome offers – BetUK being one of the three brands with a sports section, which get three choices where the casino-only sisters get two – then a form that comes in two steps and starts with an email address, then a password. It was working when tried on 13 August 2026, and registration stopped there, unfinished by design.

What the menu holds beyond the sport

The top strip runs Sports, Casino, Live Casino. Under the sports side sit live betting, football – Premier League first – horse racing and tennis, plus the sports offers page; on the casino side the lobby opens with slots, new games and jackpot shelves, with the live tables one tab further along. It is the same two-product shape BetMGM uses, which is no surprise when one platform serves the whole account – but here the sport takes the front seat everywhere it can.

How the sports pair differ

BetUK and BetMGM advertise the same £40 sports welcome, ask the same £10 bet to unlock it, and trade on the same permissions, so the difference between them is emphasis rather than equipment. BetMGM pairs its free bets with the biggest spin offer on the account; BetUK, on 13 August, advertised the free bets alone. A bettor who wants casino spins in the same wallet leans one way, a bettor who wants a sportsbook that reads like a sportsbook leans the other, and both answer to the same licensee if anything goes wrong.

Terms dated 6 August 2026

The BetUK terms are the freshest copy of the group document: version V6.1, edition dated 6 August 2026, a week old when read – the LeoVegas copy of the same V6.1 still says 24 June. For a betting customer the clause that matters most sits near the top: sports winnings are capped at £250,000 on a bet, whatever the stake or the odds. The document names all six brands, allows one account per brand, and describes customer funds as segregated at the medium protection level, which speaks to how money is held rather than guaranteeing its return. Company number C59314 appears there too, against the Sliema head office.

Announced in 2018 and 2022, absent from the register

Account 39198 shows a zero for regulatory actions, and the separate actions register returns nothing for this licensee however it is searched. Even so, there are two announced penalties: £600,000 in May 2018 and £1.32 million in August 2022, the second accompanied by an official warning and a required audit. Neither appears on the register today because closed cases fall away from it. The full accounting of both, with the announcement links, is in the account file.

Leaving the sportsbook without leaving the licence

A BetUK customer after richer casino furniture has the pick of the family: Leo Vegas for the deepest catalogue, BetMGM for sport and casino together, or Slot Boss for a smaller room. One caution travels with the choice: a single self-exclusion covers all six brands, so a break from BetUK is a break from the lot. The rest of the coverage files under the Leo Vegas PLC tag.
