How We Review Casinos and Sister Sites

Every brand on New Sister Site goes through the same process before it’s published or updated. This page explains exactly what that process involves, so you can judge for yourself how much weight to put on what we say.

1. We verify the licence first

Before we write a word about bonuses or games, we look up the operator on the UK Gambling Commission’s public register and confirm the exact licence number, the licensed entity name, and whether that licence is currently active. If a brand isn’t UKGC-licensed, we identify which regulator it does hold a licence from (Curaçao, Kahnawake, Anjouan, Malta, and so on) and state that plainly at the top of the review, not buried in the small print.

2. We map the network

Most UK casino and bingo brands aren’t standalone businesses — they’re white-label skins or sister brands sharing a platform, a licence, or a parent company with several other sites. We trace the operator back to its parent group (companies like White Hat Gaming, 888 Group, Progress Play, Gamesys, SkillOnNet, Jumpman Gaming, and others), and list the closest genuine sister sites: brands that share the same operator, software, or ownership, not just a similar name or colour scheme.

3. We check how the site actually behaves

Where we can create and use an account, we look at how deposits and withdrawals are handled, read the actual bonus terms rather than the marketing summary, and note anything that affects a UK player specifically — payment methods, KYC requirements, and how the site handles UK responsible gambling tools like GamStop and deposit limits.

How we handle offshore and non-UKGC brands

We cover some casinos that hold no UK licence at all. These pages exist as background research and a warning, not a recommendation: we explain who operates the brand, why it isn’t available to UK players through legal channels, and what that means practically (no GamStop coverage, no UK dispute resolution via IBAS, and in some cases active geo-blocking of UK visitors). We do not place affiliate or promotional links on these pages. If you land on one of these reviews from a search for a brand you already use, please read the licensing section carefully before doing anything else.

Keeping reviews current

Licences lapse, operators change hands, and networks get bought and sold. We periodically re-check our highest-traffic reviews against the UKGC register and update the “last checked” date on each page when we do. If you spot something that’s gone stale, tell us — see the section below.

Corrections and complaints

If you believe something on this site is factually wrong — a licence number, an ownership link, a closed brand we’ve missed — please get in touch. We’d rather fix it than leave it. For how the site is funded and our editorial independence policy, see our Editorial Policy.
