How we rank betting sites in the UK

What we rank

Our ranking of the best betting sites in the UK compares online bookmakers licensed by the Gambling Commission. To qualify, a bookmaker must hold an active remote betting licence and its web address must be on the Commission’s public register, which we read from the Commission’s register files of October 22, 2026. Betting exchanges, which hold a separate betting intermediary licence and charge commission instead of building a margin into their odds, have their own ranking.

The six criteria

Each criterion gets a rating from 0 to 10; the overall score is the weighted average, rounded to one decimal, and the ranking follows it.

How we judge odds without scraping them

Price matters more than anything else to a regular bettor, because the margin a bookmaker builds into its odds is what betting costs you. But the bookmakers in our ranking forbid automated collection of their odds. Sky Bet’s terms (section 13.6) say the odds and other information on its sites are “for Your personal use only”, and section 17.2 bans “any artificial intelligence, automated players (bots) or player assistance software”. Midnite’s terms let it act against anyone who uses automated systems to copy or extract its data, “sometimes referred to as ‘screen scraping’”, or makes commercial use of its odds; bet365’s UK terms say the same. We don’t break those terms, so the odds criterion scores what each bookmaker publishes:

• Maximum payouts. Higher caps let big winning bets pay in full: bet365’s £2 million a day on the Premier League scores best, William Hill’s £1 million and Paddy Power’s £1 million well, Sky Bet’s £500,000 less, and Midnite’s £250,000 a day lowest.
• Best Odds Guaranteed. Whether you’re paid the starting price when it beats the price you took, and who gets it: anyone who opts in at Paddy Power (in its January 2025 terms), Sky Bet Club qualifiers at Sky Bet, and invited customers only at William Hill and Midnite.
• Minimum stakes and published terms, such as William Hill’s 3p stakes and Midnite’s published each-way place terms.

No bookmaker in our ranking publishes its margins. Our margin calculator works out the margin on any market and shows which of two bookmakers pays more.

How regulatory action lowers the licensing score

We check two Gambling Commission sources for every bookmaker and every company behind it: the regulatory action register, which lists sanctions and settlements decided since November 2023, and the Commission’s enforcement news, which we read back to March 2021. A current licence with no action in either starts near the top. Each fine or settlement costs points, more when it’s large, recent or about protecting players, and repeated cases cost the most:

• William Hill scores lowest (6.5): its licensee paid £12.5 million in March 2023, part of a record £19.2 million for William Hill businesses, and was fined £82,687 in August 2025.
• Paddy Power (7.5) was part of a £2 million settlement in December 2025 over how it interacted with customers at risk of harm.
• bet365 (8.5) settled for £239,085 in April 2024, £582,120 with its casino sister.
• Sky Bet (9.5) and Midnite (8.5) have no action on record in either source; Midnite scores lower because its current licence dates from August 2026 and its earlier operator’s from 2018, against 2014 for Sky Bet’s.

Actions before March 2021 aren’t counted, because we haven’t checked them for every bookmaker.

How we rate the other criteria

• Markets & features: the number of sports and events, football and racing depth, in-play betting, bet builders, cash out (partial cash out counts extra) and free streaming, from each bookmaker’s rules, help pages and app listings.
• Payments & payouts: published withdrawal times count most, then fees, minimums and the choice of methods. Where a bookmaker’s UK pages block visitors from outside the UK, we use dated Internet Archive copies, and a bookmaker whose withdrawal times we couldn’t check at all scores conservatively.
• App & experience: ratings on the UK App Store and Google Play on the date checked, weighted by how many people rated them.
• Support & responsible gambling: hours and channels, with 24/7 support or a phone line scoring highest, plus the range of limits, time-outs and self-exclusion, and affordability checks.

What we leave out

Bonuses and promotions. We don’t list or score welcome offers or free bets. Since January 19, 2026, the Commission has capped wagering requirements at 10 times and banned offers that mix betting with casino or other products, but an offer’s value still depends on terms that change constantly, and it’s a poor reason to choose a bookmaker. Unlicensed bookmakers, which it’s a criminal offence to offer or advertise to people in Great Britain, are never ranked.

Where our facts come from

The Gambling Commission’s register files and regulatory records, each bookmaker’s terms, rules and help centre, and the UK App Store and Google Play, each dated on the page. Where a live page couldn’t be read from outside the UK, we used a dated Internet Archive copy and say so in the review.

Independence

SafeBet.ai may be paid by bookmakers whose links are marked as advertising, but a bookmaker can’t buy a place or a score. See our editorial policy, and tell us if something’s out of date.
