Why SisterSitesHub?
Three things every UK player needs before signing up — and almost no other affiliate publishes them transparently.
Full operator graph
Every brand mapped to its parent group, sister sites and licensing authority — not just a list of bonuses.
Independent trust scoring
We score each operator on licensing, complaint history, payout speed and dispute resolution. Operators cannot pay to improve scores.
Live payout verification
Our team tests withdrawals on each platform every 30 days. Reported times are real, not marketing copy.
The Basics
What are casino sister sites?
Sister casino sites are separate gambling brands owned by the same parent operator. They share licensing, payment systems, KYC databases and responsible-gambling tools — but each brand offers its own welcome bonus, theme and game catalogue.
In the UK, every casino sister site in our directory is cross-referenced against the UK Gambling Commission public register to confirm corporate ownership and licence validity.
| Feature | Usually shared | Usually differs |
|---|---|---|
| UKGC licence | ||
| Payment processor & KYC | ||
| Self-exclusion (GamStop) scope | ||
| Game library catalogue | ||
| Welcome bonus offer | ||
| Wagering requirements | ||
| Brand theme & UX | ||
| VIP / loyalty programme |
Operator Comparison

Six of the largest UKGC-licensed casino operators control roughly a third of all branded casino sister sites in the UK. Compare their network size, flagship brands and trust profile below.

| Entain plc | 22 | Ladbrokes | 95 |

Updated May 2026
New UK sister casino sites for 2026
Launch-window welcome bonuses are usually the most generous a brand ever offers — gaming groups front-load promotional budgets to drive early registrations. Here are the newest UK sister casino sites this quarter, each holding a verified UKGC licence.
| New brand | Launched | Launch bonus | Trust |
|---|---|---|---|
| Quick Bet Casino | Jan 2026 | 100% up to £100 | 86 |
| Spin Fever | Feb 2026 | 500 Free Spins | 82 |
| Reel Spinner | Mar 2026 | £10 No Deposit | 88 |
| AK Bets Casino | Apr 2026 | £40 Welcome Pack | 81 |
| Pink Casino Vault | Apr 2026 | 200 Free Spins | 87 |
| FanDuel Vegas | May 2026 | £200 First Deposit | 93 |
Verify before you deposit. A new sister casino site inherits its parent group's compliance record, but the specific brand's UKGC licence number may be only weeks old. Always check the operator's entry on the UKGC public register directly. 18+. Gamble responsibly.
Player-friendly
No-wagering sister casino sites
No-wagering casino sister sites let you keep what you win from bonus spins or bonus cash — no playthrough requirements before withdrawal. They're rarer than headline-grabbing matched-deposit offers, but they're objectively the highest-value bonus type for serious UK players.
All operators listed below hold a UKGC licence and have been payout-tested by our team in the last 30 days.
| Sister site | No-wager offer | Payout | Score |
|---|---|---|---|
| PokerStars Casino | £10 free play, no wagering | < 4 hrs | 97 |
| Sky Vegas | £10 free play, no wagering | < 12 hrs | 89 |
| 32Red | No-wagering slots bonus | < 24 hrs | 89 |
| Ladbrokes | £20 free bet, no wagering | < 16 hrs | 92 |
| Coral Casino | £20 free bet, no wagering | < 16 hrs | 91 |
| BetMGM Casino | £1,000 welcome, 1x play | < 8 hrs | 93 |
Side-by-side
Sister casino sites vs independent casinos
Both are legitimate options under UK regulation — but they trade different things for different player needs. Use this comparison to decide what matters more to you.
| Dimension | Sister sites | Independent casinos |
|---|---|---|
| Compliance track record | Inherits parent group's UKGC history | Must be evaluated brand-by-brand |
| Welcome bonus stack | Multiple separate welcomes across the group | Single welcome per brand |
| Bonus eligibility | Group-level abuse checks — restrictions apply | Fully independent eligibility |
| Withdrawal infrastructure | Shared, mature payment rails | Varies — newer brands may be slower |
| KYC / verification | Single KYC carries across all siblings | Fresh KYC per brand |
| Self-exclusion scope | Group-wide — affects all siblings | Contained to one brand |
| Innovation / niche features | Conservative — proven tech | More room for niche specialisation |
| Customer support quality | Shared, scaled support team | Highly variable |
Sister sites are best when…
You value reliable payouts, want to stack welcome bonuses across multiple brands, or prefer the safety net of a large UKGC-licensed operator.
Independent casinos are best when…
You want niche themes, novel game providers, or features the big groups don't prioritise — and you're willing to verify the brand's track record yourself.
Reform · January 2026
UKGC 10x wagering cap — what it means for sister sites
On 1 January 2026, the UK Gambling Commission introduced a hard 10x maximum wagering requirement on every welcome bonus offered by UKGC-licensed operators. Before the cap, wagering of 35x–60x was industry standard. The reform was designed to make bonus terms transparent and withdrawable — but the consequences ripple right across every sister casino site in the UK.
Many operators removed wagering entirely rather than redesign bonus economics around 10x. Others slashed headline bonus values to compensate. The table on the right shows what changed for the bonuses our research team verified across the six largest sister-site networks.
| Sister site | Before Jan 2026 | After Jan 2026 | Verdict |
|---|---|---|---|
| PokerStars | £200 match · 35x wagering | £200 match · 1x wagering | Vastly improved |
| Sky Vegas | £10 free spins · 40x | £10 free play · no wagering | Removed wagering |
| Ladbrokes | £30 match · 40x | £20 free bet · no wagering | Lower value, cleaner terms |
| Unibet | £40 pack · 35x | £40 pack · 10x | Headline kept, wagering down |
| LeoVegas | £400 + 200 spins · 35x | £100 + 50 spins · 10x | Headline value cut 75% |
| 32Red | £160 match · 30x | £40 no-wager slots | Simpler, fairer |
How to spot a real low-wagering sister site
Not every operator advertising "low wagering" actually offers good value. Look for three things in the T&Cs:
- Wagering applies to bonus only — never to bonus + deposit (a hidden multiplier).
- Maximum cashout cap is removed or generous — a £10 bonus capped at £100 winnings cancels the value.
- Bonus expiry is 7+ days — 24-hour expiry on a 10x wager is statistically near impossible.
Tax Change · 1 April 2026
The 40% Remote Gaming Duty — why your bonuses got smaller
On 1 April 2026, HMRC increased the Remote Gaming Duty from 21% to 40% — the biggest single tax change in UK online gambling history. Operators have three ways to absorb that cost: cut bonuses, cut RTPs, or cut marketing spend. So far, they've mostly cut bonuses. Here's how each of the major sister-site groups responded.
| Operator group | Bonus strategy | Net player impact |
|---|---|---|
| Flutter Entertainment | Kept headline values, shifted toward no-wagering across PokerStars + Sky brands | Best for players |
| Entain plc | Reduced welcome offer cash value by ~30% on Ladbrokes/Coral | Smaller bonus, same odds |
| Kindred Group | Kept Unibet pack at £40, switched 32Red to no-wagering structure | Quality preserved |
| Evoke (888) | Shifted toward in-play promotions and loyalty over welcome bonuses | Hidden cost to players |
| LeoVegas Group | Cut headline welcome value by ~75% (£400 → £100) | Significant bonus reduction |
| Jumpman Gaming | Mostly free-spin restructures; bonus cash mostly removed | Different format, similar EV |
What to look for
- Groups keeping headline bonus values stable
- Operators publishing RTP changes transparently
- Brands shifting to no-wagering bonus structures
Red flags
- Unannounced RTP cuts on existing slots
- New "exclusive" slots with sub-94% RTPs
- Bonus T&Cs changing mid-week without notice
Self-Exclusion · Important
Does GamStop apply to all sister sites?
Short answer: yes — across every UKGC-licensed sister site, automatically. But the scope of self-exclusion is one of the most misunderstood topics in UK gambling. Here's exactly how GamStop interacts with sister-site networks, and what falls outside its reach.
| Scenario | GamStop applies? | What this means |
|---|---|---|
| Excluding from one Flutter brand (e.g. PokerStars) | Automatically blocks Sky Vegas, Betfair Casino, Tombola, and every other Flutter UK brand | |
| Excluding from one Kindred brand (e.g. Unibet) | Blocks 32Red, Maria Casino, and all Kindred UK siblings simultaneously | |
| A new sister site launched mid-exclusion period | New UKGC operators must integrate with GamStop before launch | |
| Offshore (non-UKGC) casinos using the same brand name | Not covered — but you should still respect the exclusion. Contact GamCare on 0808 8020 133. | |
| Sports betting brands by the same operator | GamStop blocks sports + casino + bingo + poker across all UKGC platforms | |
| Trying to register with a different email or address | GamStop cross-checks name + DOB + address fingerprints. Bypass attempts fail. | |
| Lifting exclusion before its end date | Impossible. Exclusion runs its full term (6 months minimum) with no early opt-out. |

Frequently asked questions
What are casino sister sites?
Casino sister sites are separate gambling brands owned by the same parent operator. For example, Unibet, 32Red and Maria Casino are sister sites because all three are owned by Kindred Group. Sister sites share licensing, payment systems and responsible-gambling tools, but each brand offers a distinct welcome bonus, theme and game library.
How do UK casino sister sites work?
UK casino sister sites all operate under a single UKGC licence held by the parent operator group. The group runs each brand on shared back-end infrastructure — meaning the same payment processor, KYC database and GamStop self-exclusion register — but presents each brand with its own domain, name, design, bonus offer and game selection. This lets one operator serve different player demographics through visually distinct brands while keeping compliance costs centralised.
Are sister casino sites safer than independent casinos?
Sister casino sites owned by large UKGC-licensed operator groups generally have stronger compliance, faster payouts and better customer support than smaller independent casinos, because the group shares mature infrastructure across all brands. However, safety ultimately depends on the parent group holding a valid UKGC licence with a clean compliance record. A new sister site inherits its parent's track record, which is why operator-group due diligence is the first step in choosing where to play.
Can I claim a welcome bonus on every sister site?
Usually no. Most UK operator groups restrict welcome bonuses to one per household across all their sister brands. PokerStars and Sky Vegas, for example, both run on Flutter Entertainment's group-level bonus-abuse detection system. Always check the terms before depositing — bonus eligibility is normally enforced at the group level, not the individual brand level.
What are the biggest casino sister site networks in the UK?
The largest UK casino sister site networks by brand count are: Jumpman Gaming (56+ brands), Entain plc (22 brands including Ladbrokes and Coral), Flutter Entertainment (19 brands including PokerStars, Betfair and Sky Vegas), Evoke / 888 Holdings (11 brands), Kindred Group (9 brands including Unibet and 32Red), and LeoVegas Group (6 brands).
What are no-wagering sister casino sites?
No-wagering sister casino sites are operator brands that offer welcome bonuses with no playthrough requirements — any winnings from bonus spins or bonus cash can be withdrawn immediately. They're rarer than standard match bonuses but objectively higher-value. UK examples include Sky Vegas, PokerStars Casino, 32Red (no-wagering slots offer), and Ladbrokes/Coral's £20 free bets.
How is SisterSitesHub funded?
We earn affiliate commission from some of the casinos listed when readers sign up via our links. This never affects our review scores — operators cannot pay for placement, and we publish a full affiliate disclosure on every review page. Our trust scoring is independent and recalculated every 90 days.
What is the UKGC 10x wagering cap?
On 1 January 2026, the UK Gambling Commission introduced a hard 10x maximum wagering requirement on every welcome bonus offered by UKGC-licensed operators. Previously, wagering of 35x–60x was industry standard. After the cap, many operators removed wagering entirely rather than redesign bonus economics — for example, PokerStars dropped to 1x wagering, Sky Vegas removed wagering on its £10 welcome offer, and Ladbrokes switched to a no-wagering £20 free bet.
Why did UK casino bonuses get smaller in 2026?
On 1 April 2026, HMRC increased the Remote Gaming Duty from 21% to 40%. This near-doubling of operator tax forced casinos to absorb costs somewhere — most chose to reduce welcome bonus values. Flutter and Kindred preserved headline bonus values but moved toward no-wagering structures; LeoVegas cut its £400 + 200 spins welcome to £100 + 50 spins; 888 lowered RTPs on 14 in-house slots by 0.3–0.8%.
Does GamStop apply across all sister sites?
Yes. GamStop covers every UKGC-licensed online operator automatically. If you self-exclude through one sister site like PokerStars, you are immediately blocked from every other Flutter brand including Sky Vegas, Betfair, Paddy Power and Tombola. The same applies across Kindred, Entain, Evoke, LeoVegas and every other UKGC group. Self-exclusion runs its full chosen term (6 months minimum) and cannot be lifted early.
