bet365 Sister Sites

Every brand on licence 38721, 55148, 55149

No other brand with a page on this site sits on this licence account. The register names it also carries are listed in the next section.

How the group is structured

bet365 is the only brand on account 38721, 55148, 55149 with a page on this site, but not the only name the Gambling Commission holds against that account. The register also lists bingoheads — printed exactly as the register prints them. A registered name can be a separate website, a chain of betting shops or the company's own name, and the register does not say which, so this page does not either.

Those accounts are held by three companies — 38721 (Hillside (Technology) Limited); 55148 (Hillside (UK Sports) ENC); 55149 (Hillside (UK Gaming) ENC) — and the names above are drawn from all of them.

Is bet365 safe?

bet365 holds a current Gambling Commission licence under account 38721, 55148, 55149. That is the part you can verify yourself, and it is the part that matters: a UK licence brings segregated customer funds, a named alternative dispute resolution route, mandatory age verification and GAMSTOP participation.

What a licence does not tell you is how the operator behaves — how fast withdrawals clear, how it handles a disputed bonus, how heavy the verification is. That is worth reading reviews for. What we publish here is the record, not a score.

To check it yourself: open the Gambling Commission public register, search Hillside (Technology) Limited, and confirm account 38721, 55148, 55149 lists bet365 as a trading name. It takes about thirty seconds and it is the only source that cannot be marketed at you.

GAMSTOP and self-exclusion

Because bet365 is licensed by the Gambling Commission, a GAMSTOP self-exclusion blocks it. It also blocks every other brand on account 38721, 55148, 55149 and every other UK-licensed gambling site, in one registration.

This is the reason the "sister site" question matters to people who have self-excluded. You cannot get round GAMSTOP by moving to a sibling brand, and any site advertising itself as outside GAMSTOP is not UK-licensed. We do not list those, and we do not link to them.

If gambling is causing you harm, the National Gambling Helpline is free on 0808 8020 133, 24 hours a day.
