How We Rate Casinos & Bonuses

Last updated 11 November 2026

Bonus Boss explains UK casino bonuses and lists casinos licensed by the UK Gambling Commission. This page sets out how pages are made and how casinos are rated, so you can judge the guides for yourself.

Only UKGC-licensed casinos

Every casino listed holds a current UK Gambling Commission licence. We confirm the licence on the Gambling Commission public register before a casino is added, and we do not list sites that are not licensed for Great Britain.

How offers are checked

Each bonus is read from the operator’s own terms and recorded as shown: wagering, minimum deposit, maximum win or cashout, game weighting and expiry. The operator’s current terms always take precedence over anything on this site, so we show a last-updated date and recheck regularly.

What the rating weighs

  • Wagering requirement and whether winnings are paid as cash
  • Maximum win or cashout cap on the bonus
  • Minimum deposit and how the offer is claimed
  • Range of payment methods and clarity of the terms

Ratings are editorial and are there to compare offers at a glance, not a guarantee.

How pages are written

Guides are prepared with software tools, including AI, and reviewed by an editor before publishing. Author names are pen names; their bios describe only their work on this site. See our team.

How we are funded

Bonus Boss earns a commission if you sign up with a casino through a link here. A commercial partnership can affect the order casinos appear in, but not the facts we publish about them. Pages are marked #Ad and offers carry 18+ and responsible-gambling notes. See Responsible Gambling.
