3. What UK Standards Should Bulk Door Locks Meet?

UK building regulations require locks to meet strict safety and security standards. Always check for:

• BS 3621 Certification

High-security mortice locks often required by insurers.

• PAS 24 Rating

Mandatory for new homes under Approved Document Q.

• BS EN 12209

Mechanical lock durability standard.

• BS EN 1303
