UK smart lock buyers face compatibility, fitting and insurance checks

In a guide published on 2 November 2026, the Guardian examined smart locks for British homes, from devices fitted over existing locks to replacement handles and electronic cylinders. Entry options include phones, codes and fingerprints, with some models supporting remote access. Prices ranged from below £100 to more than £1,000; locksmith Shane Hales put a good-quality unit’s starting price at £200–£250, excluding installation.

The report emphasised matching the device to the door and checking insurance conditions before making changes. The Association of British Insurers said policyholders should review their terms and consult their provider about lock requirements. Some insurers may also require professional installation. Security checks highlighted included the BSI Kitemark and Sold Secure’s SS504 certification.

British front doors use varied materials and locking arrangements, and the guide warned that many US imports would not suit UK cylinders. That makes compatibility a practical constraint on keyless upgrades. Longevity also affects the comparison: Hales estimated five to six years for smart locks, while the MLA’s Steffan George described much longer service from traditional locks.
