The 5 Lever Mortice Deadlock

If you have been wondering what a BS3621 lock is, after being informed that it is a requirement for your home insurance policy, read on.

This lock which has become a standard in homes throughout the UK, was created with the intention of significantly increasing the security levels of exterior entrances on a property. The most significant feature of the BS3621 is the 5 lever deadbolt, for which it is famous. The lock is suitable for external doors made from timber and some steel doors.

Why is it so important to check if you have a BS3621 lock installed?

Well for a start, it can withstand most amateur attempts of lock picking, drilling and forced break in attempts. In addition to this, property's that don't have the minimal security requirements of BS3621 locks may not receive compensation in cases of theft. We recommend you check, that your existing doors locks are certificated to BS3621 standard. If your lock is certified you will clearly see the British standard kitemark on the face plate of the lock.
