Which house locks do insurance providers favour?
The more secure the lock, the better it will be regarded by insurance providers. A five lever mortice lock is one that’s frequently regarded to have a good standard of security, especially when the lock conforms to the correct British Standard (usually BS 3621). A mortice lock requires a key both to open and lock it.
Some of the most secure locks include multi point locking systems, in particular SS312 Diamond approved cylinders, which are usually found on uPVC and composite doors. Multi-point locks have a minimum of three locking points that all lock at the same time when you turn the key. For example, a door could lock at key level and bolt the door into the frame at the top and the bottom. If you have sliding patio doors, you may need to install an anti-lift patio lock for increased security to stop the door being lifted off the rails.
If you pair either of these locks with a burglar alarm system that you use and maintain, even better.
While night latches are a frequently fitted and used lock type, some insurance providers may prefer that you use them in conjunction with either a five lever mortice lock or a multi-point locking system. A night latch is a lock that’s mounted on the surface of the door, instead of being morticed into to the edge of the door. Night latches can often be deadlocked.
Door bolts are a sliding bolt for a locking door, often used at the top or bottom of doors to provide additional security.
