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

Euro cylinder performance classification.

• FD30/FD60 Fire Door Certification

Essential for flats, commercial buildings, HMOs, and escape routes.

If a lock doesn’t meet these standards, it can cause inspection failures or delays—something no builder can afford.
