Insurance approved locks

What Are British Standard Locks?

British Standard locks are tested and certified to meet rigorous safety and durability criteria set by the British Standards Institution (BSI). Look for the kitemark symbol (BSI Kitemark) stamped on the lock body—this guarantees the product meets strict performance benchmarks for strength, resistance, and reliability.

The most commonly required lock by insurers is the BS3621 standard for mortice and cylinder locks.

Why Choose British Standard Locks?

Insurance Approved

Many home insurance policies require locks that meet BS3621 or other relevant British Standards. Non-compliant locks could void your coverage in the event of a claim.

High Security

BS-rated locks are tested against common break-in methods like drilling, picking, snapping, and forced entry—providing greater protection than standard locks.

Peace of Mind

When you see the British Standard kitemark, you know the lock has been independently tested and certified for quality and security.

Long-Lasting Durability

BS locks are built to withstand both wear-and-tear and environmental conditions, offering reliable security for years to come.
