Our process
How do we choose our picks?
We don’t lab-test products ourselves. Instead we synthesise current Amazon UK listings and published specs into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We check each pick against live Amazon UK catalogue data rather than last year’s model lists. Stock moves fast, so a listing can sell out after we publish.
Published specs
We compare manufacturer specifications so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage and plug/fitting standards — details that generic global lists miss.

Editor's Note
Several of these locks need an extra item for some features: the WAFERLOCK needs its R400 Gateway for remote access, the Yale Keyless Connected needs a Yale Access Module for the app, and the Aqara U600 needs a listed Aqara hub for remote unlock in the Aqara Home app and an Apple Home hub for Home Key. Only the two Yale listings state a warranty term, and only the WAFERLOCK and Aqara listings state an IP rating.
Our Take
The Aqara U600 is the default pick for UK uPVC, composite and timber doors, with the listing's 40–80mm door range, fingerprint and Home Key entry and up to 10 months of battery. Choose the WAFERLOCK C760 if you want a listed EN15684 certified profile cylinder that works offline, or the Yale Conexis L2 for lift-to-lock PVC and composite doors with a stated 2 year warranty.
