Do your door locks conform to BS3621?
January 13, 2022When it comes to filling out home insurance proposal forms, you will most likely be asked about the types of locks your doors have. It is important to make sure you know this as it might affect the price of your insurance policy, lead to a claim payment being reduced or refused as well as possibly invalidate the policy if the information is incorrect.
Here are four main types of door locks that might be in your property:
Five lever mortice deadlock
Five lever mortice deadlock conforming to BS3621
Key operated multi point locking system
Rim automatic deadlatch
Now, how do you tell if you have one of these locks? Here is how to find out and a brief description about these types of locks.
1. Five lever mortice deadlock
Do I have this type of lock? Most likely if:
- The door is made of wood
- The door is lockable from both sides with a key
- The words ‘5 LEVER’ are engraved on the faceplate
Most likely not if:
- The door is UPVC or composite
- The lock is on the surface of the door
This type of lock is a standard deadlock and is not the most robust when it comes to security. You would most likely see this type of lock on an external front door and an external back door. The location of the lock would be in the leading edge of the door.

2. Five lever mortice deadlock conforming to BS3621
Do I have this type of lock? Most likely if:
- The lock has the British Standard Kitemark engraved on the faceplate
- The words ‘5 LEVER’ are engraved on the faceplate
- The face plate of the lock will state the standard code BS3621
Most likely not if:
- Found on internal doors
- There are 3 levers
This is the door lock of choice for many insurers and some insurance companies might insist you have this type of lock to get cover. This type of lock is much more secure than a standard five lever mortice deadlock due to its anti-pick qualities, hard plates to protect the lock from drilling and having a minimum of 20mm bolt throw into the door frame.

3. Key operated multi point locking system
Do I have this type of lock? Most likely if:
- The door is UPVC or composite
- You turn the handle up to lock it and turn the key
- There are multiple lockable points along the height of the door
Most likely not if:
- There is more than one lock cylinder
- If your house is older and less modern
A multi-point locking system will engage at least three bolts into the door frame at different height intervals. More locking points make it harder for burglars to enter. You often see these types of locks on external doors such as patio and French doors. The advantage of having this type of lock is that you can upgrade to a better standard cylinder.

4. Rim automatic deadlatch
Do I have this type of lock? Most likely if:
- The deadlatch is fitted on the inside of the door
- The Key locking cylinder is on the outside of the door
- You have a mortice lock fitted on the door as well
Most likely not if:
- This is the only lock on your door
- Your door is made of UPVC
Deadlatches look chunky and are often found on wooden doors but also can be found on glass panelled doors. The lock will be set on the surface of the door rather on the inside edge. When you shut the door with this type of lock, it will lock automatically. These locks are often referred to as night latches.
