New Sister Sites: Trusted UK Alternatives to the Brands You Already Enjoy

Welcome to New Sister Site, your guide to finding casino and bingo sister sites across the UK. If you have a favourite online casino and want to discover others like it, you are in the right place.

We track which sites belong to the same operators, run on the same software and offer a similar experience, so you can find new places to play without the guesswork. Every review makes the licence position clear, including whether a brand is UKGC licensed, offshore licensed, recently changed operator, or not suitable as a recommendation for UK players. We do the digging so you can spend less time searching and more time enjoying the sites that suit you.

What is a sister site?

A sister site is an online casino or bingo site that shares the same owner as another brand you might already know. Operators often run several sites under one roof, using the same games studios, payment methods and support team behind the scenes. From the outside the sites look different, each with its own name, design and welcome offer, but underneath they are run by the same company.

People look for sister sites for all sorts of reasons. Some have enjoyed one brand and want others built on the same trusted platform. Others are after a fresh welcome offer, a different theme or a wider choice of games. Knowing which sites are connected makes it far easier to find somewhere new that still feels familiar.

Why use our website?

  • Honest, up to date information. We tell you plainly which brands are related and what they have in common, and we keep our pages current as the market changes.
  • Clear licence status. We only ever point you towards operators licensed by the UK Gambling Commission, so you can play with confidence.
  • Clear, useful detail. For every site we cover, we sum up the games, banking options, customer support and bonus terms in plain English.
  • Responsible gambling first. Everything we do is built around keeping play safe and enjoyable, never around chasing losses.

How we review the sites we feature

We take a careful, consistent approach to every site on this website. Before we recommend anywhere, we check that it holds a valid UK Gambling Commission licence, look at the range and quality of its games, test how straightforward it is to deposit and withdraw, and read the bonus terms in full so we can tell you what they really mean.

We also revisit our pages regularly. The online gambling world moves quickly, and yesterday’s details are not always today’s, so keeping our information accurate matters to us as much as it does to you.

Casino bonuses and the 2026 rule changes

If you have claimed a casino bonus lately, you may have noticed the terms look different to how they used to. On 19 August 2026 the UK Gambling Commission brought in new rules that changed how bonuses work across every licensed site, and on the whole the changes are good news for players.

The headline change is a cap on wagering requirements. UK licensed sites can no longer ask you to wager more than ten times a bonus before you withdraw any winnings from it. That replaces the much higher requirements of thirty, forty or even fifty times that were common before, which makes it far easier to see what a bonus is genuinely worth.

A few other changes are worth knowing about. Sites now have to show you the key terms of an offer, such as the wagering requirement, the games it applies to and any cap on winnings, before you sign up, rather than tucking them away in the small print. Bonuses can no longer mix different products together either, so an offer for casino games has to be exactly that, with no need to bet on something else to unlock it.

For you, the upshot is simpler. Bonuses are now clearer, fairer and easier to understand. Whenever we tell you about an offer, we will always point you to the terms that matter most, so you know precisely what you are agreeing to before you claim.

Bingo sister sites

It is not only casinos that have sister sites. Many of the UK’s best loved bingo brands are connected too, often sharing the same rooms, jackpots and friendly community. If you enjoy a particular bingo site, there is a good chance others are run by the same team, each with its own rooms and promotions. We cover these alongside the casinos, so whatever you like to play, you can find related sites worth a look.

Playing responsibly

Gambling should always be fun, never a way to make money or to escape from money worries. Every site we feature is strictly for adults aged 18 and over. We recommend UK-licensed (UKGC) operators for real-money play; where we also cover offshore or non-UKGC brands, those reviews are clearly flagged as warnings and background research, not recommendations, and we do not carry promotional links to them.

If you ever feel your gambling is becoming a problem, free and confidential help is available at any time:

  • National Gambling Helpline on 0808 8020 133, run by GamCare.
  • GamStop at gamstop.co.uk, which lets you self exclude from all UK licensed sites in one place.
  • BeGambleAware at begambleaware.org, for advice, tools and support.

We would always rather you took a break than carried on when playing stops being enjoyable.

Frequently asked questions

What does sister site actually mean?

It simply means two or more gambling sites share the same owner or operator. They often use the same software, payment methods and support team, even though each one has its own name, look and offers.

Are sister sites safe to use?

The sites we feature are licensed by the UK Gambling Commission, which sets strict rules on fairness, security and player protection. As with any site, it is still worth reading the terms before you sign up, and we help by summing up the important points for you.

Can I use the same account across sister sites?

Usually not. Even when two sites share an owner, you normally need to register separately at each one. That also means you can often claim a new player offer at each site, subject to its own terms.

How can I tell if a site is UK licensed?

A licensed site will display its licence details, normally in the footer, and you can check the operator on the Gambling Commission’s public register. Every brand we cover is licensed in the UK.

What is the maximum wagering requirement in the UK now?

Since 19 August 2026, UK licensed sites cannot set a wagering requirement higher than ten times the bonus amount. This is one of the most player friendly rules in any regulated gambling market.

18+ only. Gambling can be addictive. Please play responsibly.
