British Standard locks
A British Standard lock is one tested and certified to a BSI standard — for door locks, usually BS3621. Certified locks resist picking, drilling and forcing for set periods and are marked with the BSI kitemark.
Most insurers require British Standard locks on external doors. Related standards include BS8621 (keyless egress from inside) and BS10621 (for multi-occupancy buildings).
