Nothing else sits on this licence – checked 15 August 2026
Bet600 has no sister sites. The licence behind the brand belongs to Tyche Tech Limited on account 44731, and that account carries one trading name, bet600, alongside one web address, www.bet600.co.uk. Nothing further is filed against it.

Two other books, and what each one pays for
Neither name below is a sister site of Bet600. They are separate companies on separate licences, chosen because Bet600 puts its money into a weekly calendar rather than one big welcome offer, so one of them does the same and the other does the opposite.
One name, one address, and nothing else filed
Selling gambling to people in Britain needs a licence from the Gambling Commission, and every licence granted is published free for anybody to read. Account 44731 is where Tyche Tech Limited sits in that published record.
Read on 15 August 2026, the account holds one trading name, bet600, marked Active. It holds one web address, www.bet600.co.uk, also marked Active. The counters at the head of the file say 1 and 1, and the tables underneath list one entry each, so the two agree. No premises are recorded, which is what an internet only bookmaker looks like.
The regulatory actions page carries no table at all and prints one line saying that none has been recorded for the business. That sentence describes the contents of a public file. It says nothing whatever about matters that were never written into it, and no broader meaning is taken from it here.
A search of the business records for the stem bet600 returns a single result, and it is 44731. No second company files the name and no second address is filed by Tyche Tech Limited.
The permission this licence does not carry
Three permissions sit on the account and all three are Active. Betting on real events has been switched on since 24 May 2016. A casino permission and a gambling software permission were added later, both on 29 January 2020, nearly four years after the betting one. All three cover gambling sold over the internet rather than across a counter in a shop.
What is absent is the fourth thing a British bookmaker can be licensed for: betting on virtual events, meaning the computer generated races and matches that run to a timetable of their own. It is not on this licence. Set the site against the file on 15 August 2026 and the two match, because the menu offers sports, live sports, a casino and live casino, and there is no virtual section to click.
The gambling software permission is the one that stands out, because it is not something every single brand bookmaker holds. What Tyche Tech Limited does with it is not stated on the licence file, and nothing is guessed about it here.
The offers running on the site in August 2026
Read on the site on 15 August 2026, the joining offer asks for activity rather than a large deposit. Five qualifying bets are needed, each of at least £10 and each priced at 2.0 or better, all placed inside seven days of the account opening, and a £10 free bet follows.
The rest goes into a weekly calendar. Monday to Friday, £50 staked on slots inside a day returns 10 free spins. A three fold or longer accumulator of £10 or more at the weekend gives a quarter of the stake back as a free bet, to a ceiling of £25, when a single leg lets it down. Monday adds a £10 free bet for £20 or more on a football treble. Winnings from pre match bets of £30 or more carry a 3 per cent boost capped at £30, and a tennis accumulator bonus pays up to 15 per cent extra on multiples priced at 1.7 or longer.
Smaller offers sit behind those. A first goalscorer bet on a Premier League or Champions League match that finishes goalless is refunded as a free bet worth up to £25. A horse beaten into second place returns a free bet of up to £15. Best odds guaranteed applies where the starting price beats the price taken. Recommending the site to somebody else pays £5 to each of you once the newcomer reaches a third £10 free bet.
Every figure above was read on 15 August 2026 and carries that date. Promotions of this kind are altered and withdrawn without announcement, so a number printed without the day somebody saw it is worth very little.
No attempt was made to open an account for this update, so nothing here sets out the details the joining route asks a new customer to hand over.
Where the sister-site claims come from
The test used here is narrow, and it is the only one that survives contact with the paperwork: two websites are sisters when one licensed company is answerable for both of them. A shared appearance is not that. A shared games supplier is not that. A shared piece of betting software underneath is not that either, and it is the commonest reason a reader is told two independent books are related.
Bet600 attracts the claim because a small bookmaker with a long promotions list looks like part of something larger. It is not. One company holds the licence, one name is filed under it, one address is filed under it, and a search for the brand returns that single account.
What software sits underneath the site is not something this page will guess at. Neither the site nor the licence file says, so no claim is made.
Who answers if something goes wrong
One company answers for everything on the site, and the site says so itself. Bet600 is described in its own footer as a brand operated by Tyche Tech Limited, company number 09828955, registered at Spaces, 9 Greyfriars Road, Reading, RG1 1NU, and licensed in Great Britain under account number 44731. The address on the licence file is the same one.
For a customer that is simpler than it sounds. A balance, an identity check, a withdrawal that has stalled and a request to self exclude all go to the same company, and there is nothing larger sitting behind it. The licence is narrow and the operation is small. Whether that suits you depends on what you want from a bookmaker, and it is worth knowing before an account is opened rather than after.
Further reading on one-brand bookmakers
10Bet runs a single book on a single licence with two web addresses filed against it. Betdaq shares its account with a second live brand, which is what a real sister relationship looks like when there is one. Midnite ended up holding two British licences for one brand. All three were checked the same way as this page.
