STS Bet Sister Sites 2026
STS Bet has no active UK sister sites. STS.BET Limited operated the sportsbook under UK Gambling Commission account 54498, but it closed to British customers on 15 February 2023 and surrendered its remote casino and betting permissions on 28 February 2023. Both stsbet.co.uk and stsbet.com are marked inactive on the public register.
STS continues as Poland’s leading bookmaker within Entain CEE, alongside Croatia’s SuperSport, but that wider corporate relationship never created UK sister sites for the closed STS Bet brand. Entain agreed a phased exit from Entain CEE in June 2026; the first 20% sale to EMMA Capital is expected to complete in Q4 2026, subject to approval.

STS Bet was the UK-facing sportsbook of STS.BET Limited, a licensee connected to the STS Gaming Group, a Malta- and Poland-based operator with a large retail betting-shop network across Poland and offices in Katowice, Warsaw, Prague and Malta. While the wider STS Gaming Group continues to trade in Central and Eastern Europe, the UK arm shut down. STS.BET Limited’s own closure notice, published on stsbet.co.uk, states that the “cessation of our operations” took effect on 15th February 2023, after which all customer accounts became dormant.
The stated reason for the closure was “the economics of operating a small iGaming business in the UK market and upcoming changes in the legislation that would impose more obligations towards operators”, in other words, STS.BET Limited judged that the compliance cost of staying in the UK no longer stacked up against the size of its UK customer base. Any bets due to settle after 14th February 2023 were voided and stakes returned, unused bonuses and free bets were forfeited, and customers with remaining balances were told to contact support with identity verification to withdraw. Dormant accounts left untouched were later warned they would start incurring a £5 inactivity fee from 10th August 2024 onward, per the operator’s terms.
The UK Gambling Commission still publishes STS.BET Limited’s account 54498. It records the remote casino, real-event betting, virtual-event betting and pool-betting permissions as surrendered on 28 February 2023, while the STS Bet trading names and both registered domains are inactive. STS.BET Limited has also been described by third-party trackers as running no other UK-facing sister sites, so there is no genuine live STS Bet sister network to list here: older write-ups that group it with brands such as Lovebet, Ohmbet, 32Red, Costa Bingo or various bingo sites are not supported by STS.BET Limited’s own closure statement or by those brands’ current, separately verified ownership.
If you held funds with STS Bet before the closure, the operator’s guidance was to contact its customer support team directly with proof of identity to arrange a withdrawal rather than expecting funds to be returned automatically.
What STS Bet Offered While It Was Live
For the four-ish years it traded here (the international site went live in 2019), STS Bet was a sportsbook first and almost nothing else: no casino tab bolted on, no bingo room, just betting. Coverage ran to more than 40 sports, from the obvious football and tennis down to genuine oddities like chess and biathlon, and the football section was the deepest part of the book with several hundred markets on big fixtures. Its Polish DNA showed in the odds: the Ekstraklasa and lower Polish divisions were priced with a sharpness UK-headquartered books rarely matched, traded by an in-house desk of over 300 staff on the group’s TGLab-built platform rather than an off-the-shelf feed.
Modern conveniences were all present, cash out, a bet builder, live betting and virtuals, and the advertised pre-match payout hovered around 95%, respectable mid-table stuff. The UK welcome offer was a 50% first-bet bonus worth up to £40. None of it was revolutionary, but reviewers generally scored it as a tidy, honest mid-sized book whose problem was never product quality: it simply could not build a British customer base big enough to carry British compliance costs.
Mobile was handled properly too, with native iOS and Android apps alongside the browser site, again more than some similarly sized rivals managed, and account features like partial cash out worked identically across all three. Former customers remembering the product fondly are not wrong; this was a closure driven by balance-sheet arithmetic, not by player complaints, regulatory sanction or unpaid winnings, and that distinction matters when you read about any bookmaker leaving a market.
The Company Behind It: From Katowice Betting Shops to Market Leader
STS started life in 1997 as a retail bookmaker in Katowice, decades before its brief UK adventure, and grew into Poland’s dominant operator, more than 440 betting shops at its peak and a share of the Polish market regularly put at around half or more. The Juroszek family built and controlled the business throughout, with Mateusz Juroszek serving as chief executive from 2012, and in December 2021 STS Holding S.A. floated on the Warsaw Stock Exchange. The 2019 push into regulated markets abroad, the UK and Estonia via the stsbet.co.uk and STS.bet sites, was an attempt to turn a national champion into an international one. The UK leg of that experiment lasted barely four years; the company’s centre of gravity never left Central and Eastern Europe.
The Entain Takeover And 2026 Ownership Change
Entain CEE acquired STS Holding S.A. in August 2023 after shareholders representing about 99.3% of the company accepted the tender offer. The deal arrived after STS Bet’s UK closure, so Ladbrokes, Coral and bwin did not become retrospective STS Bet sister sites: they used different operators, accounts and customer wallets in Britain.
The ownership position is changing again. On 25 June 2026 Entain agreed to sell a 20% interest in Entain CEE to EMMA Capital for about €425 million, with completion expected in Q4 2026 subject to regulatory approval. Entain’s holding would fall from 67.5% to 47.5%, EMMA would rise to 42.5% and the Juroszek family would retain 10%. None of this restores account 54498 or reopens STS Bet in Britain.
Why Small Bookmakers Keep Leaving Britain
STS Bet’s stated reasoning, the economics of running a small iGaming business in the UK plus legislation about to add further obligations, described a squeeze that has since claimed other niche operators. The Gambling Act review white paper published in April 2023 confirmed the direction of travel: financial-risk checks, tighter marketing rules and higher operational overheads that a market leader can absorb but a bookmaker with a small British book cannot. For players the practical lesson from this page is worth internalising: when a licensed operator exits in an orderly way, open bets get voided and returned, balances stay claimable through support, and the regulator’s register records exactly what happened, a managed ending rather than a disappearance, and precisely the protection an unlicensed site never has to offer.
Still Owed Money By STS Bet?
The closure notice still directs former customers to support@stsbet.co.uk. It also says identity verification may be required and that a £5 monthly dormant-account fee has applied since 10 August 2024, so small balances may already have been reduced.
- Email from the address used on the STS Bet account and include your full name, date of birth and former username or account number.
- Ask for a written balance statement showing withdrawals, returned stakes and every inactivity fee applied.
- Provide identification only through the operator’s stated secure route; do not email sensitive documents until support confirms how they should be submitted.
- Keep the closure notice, terms, account statements and correspondence together in case the balance is disputed.
- If there is no useful reply, write again as a formal complaint to STS.BET Limited. The UKGC record confirms the surrendered licence but the Commission does not recover individual balances for customers.
Do not open an account with another Entain or Entain CEE brand expecting the old STS balance or verification record to follow you. Those brands use separate accounts and support systems.

Who operated STS Bet?
STS.BET Limited operated the former UK sportsbook. The wider Polish STS business sits within Entain CEE alongside SuperSport, but those corporate links do not create shared UK accounts.

The UK Gambling Commission records all four remote permissions under account 54498 as surrendered on 28 February 2023. The registered domains and STS Bet trading names are inactive.
Can UK players still use STS Bet?
No. STS Bet closed its UK operation on 15 February 2023 and no longer accepts British customers.
How can a former customer claim a remaining balance?
The live closure notice tells customers to email support@stsbet.co.uk and warns that identity verification may be required. Ask for a written balance and fee statement before sending documents.
Does STS still operate outside Britain?
Yes. STS remains a major Polish sportsbook. Its continuing Polish operation is separate from the closed stsbet.co.uk service.
Did Entain’s takeover reopen STS Bet in the UK?
No. Entain CEE acquired STS after the UK closure. Entain’s planned partial divestment to EMMA Capital in 2026 also has no effect on the surrendered British licence.
