Smart Lock Buying Guide UK
Buying a smart lock for your UK home involves several considerations that differ from traditional lock purchases. This guide covers everything you need to know before making a purchase.
Compatibility Checklist
Before buying a smart lock, check your door type and dimensions. Measure the door thickness typically 40-50mm for UK doors. Measure the backset the distance from the edge of the door to the centre of the lock, typically 60mm or 70mm. Check whether you have a uPVC, composite, or wooden door as some locks are not compatible with all types.
Security Ratings
UK smart locks should carry British Standard BS 3621, Sold Secure Diamond, or SS 312 Diamond ratings. These ensure the physical lock mechanism meets UK security standards. Without these ratings, your home insurance may not cover break-ins through the smart lock.
