Mortice door locks are operated with a turn of the key, and they secure the bolt deep within the door frame, making them difficult to tamper with.

Multi-point locking systems are found on uPVC and composite doors. They work by securing multiple bolts into the door frame right up to the edge of the door, enhancing safety and energy efficiency.

Multipoint door locks are robust and fit seamlessly with found on uPVC and composite systems. This type of lock not only secures the door but also provides a tight seal to improve energy efficiency.
Night Latches
Night latches, often referred to as Yale locks, are surface-mounted on the body of the door. They are particularly convenient for quick locking when the door is pulled shut. Rim cylinder night latches allow access from the outside with a key and from the inside with a thumb turn.
A night latch can be paired with a deadbolt or mortice lock for additional security. These locks are perfect for quick entry and these common door locks are found on front doors throughout the UK.

A deadlock or deadbolt is a secondary lock often used to complement other systems. They add an extra layer of security by ensuring the bolt is manually locked into place. Single-cylinder deadbolts are common in residential properties, operated with a key externally and a thumb turn internally.
Double-cylinder deadlocks require a key from both sides of the lock, offering greater security and preventing unauthorised access to the property. Deadlocks are ideal for external doors, especially wooden doors, where additional security is paramount.
