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
Five of the six listings state a door-thickness range or limit; the EuroArt EA 225 gives door types and a 280mm size but no thickness, power source or warranty. Only the Yale states a warranty term (2yrs). The WELOCK U81 states 2 years product support, and the other listings state no warranty term. The Ultion Nuki listing states a 3-star PLUS Ultion lock; none of the other five listings names a star rating or a security standard.
Our Take
As a default, pick the Aqara U600: its listing states UK uPVC, composite and timber door fit at 40–80mm, a fingerprint reader for up to 50 prints, Matter over Thread and an IP65 outer panel. For a lift-to-lock PVC or composite door, the Yale Conexis L2 states 44-70mm, a tamper alarm and a 2yrs warranty. Where a stated lock rating matters, the Ultion Nuki listing names a 3-star PLUS Ultion lock for doors under 55mm thick.
