How to Choose the Right Locks for Your London Property
July 30, 2025
Are you looking for high-quality locks to secure the doors of your home or business in London?
Choosing the best locks for your London property may seem simple. However, doors and buildings have varying security requirements, so you need a different lock type for each one. There is no single lock solution for all doors and buildings.
Here are four tips for choosing the right locks for your London home or business. They should give you some ideas on beginning your search for the best locks to secure your property.
1) Choosing the Locking System
Most London front doors have either a mortise or tubular locking system.
Mortise locks are another name for deadlocks, which require the installer to cut a rectangular pocket into the door to make room for a deadbolt-style lock. They offer much better security and resistance than tubular locks.
Tubular locks are better suited for doors inside the home or business because they are less secure than mortise locks. Since tubular locks cost about 50% less than mortise locks, you may find them a more affordable option for indoor security. But for front and back door security, the mortise locking system offers maximum protection against burglaries and intrusions.
2) British Standard Locks
British Standard locks are official thief-resistant locks. They are typically used in front and back doors because they require an outside key to get inside whenever the door is closed. Furthermore, British Standard locks undergo vigorous safety testing against typical forced entry methods into a home or building, such as lock picking or drilling.
If the locks pass the test, they get to bear the “British Standards” stamp of approval. As a result, homeowners and business owners feel more confident with British Standard locks securing their front and back doors.
3) Lock Cylinder Features
Lock cylinders are cylindrical lock devices requiring one or more keys to lock and unlock them. The cylinders contain a series of pins that must align with the key before the door can open. A door lock cylinder with more pins will be more secure because of the increased difficulty in picking or bypassing the lock.
You may also want to consider getting a double-cylinder locking system rather than a single one for maximum security. Double-cylinder locking would undoubtedly be the best choice for protecting the front door of a home or business.
4) Smart Technology
You can now install smart lock technology into your home or business doors. It lets you control your property locks on your smartphone from afar using a Wi-Fi connection.
The smart locking system will let you know if your doors are locked or not. So, if you forgot to lock your doors, you can check the status on your phone and push a button to lock your doors.
Smart locks can be opened with either a remote-control signal or an electronic prompt from the keypad on the door lock. So you do not have to carry keys around or worry about losing them.

It’s a critical step in ensuring your property remains secure, especially when key control is uncertain.

Wear and tear: Over time, locks can become loose or malfunctioning, making them less secure.

A professional locksmith can recommend and install compliant hardware. 2.

Lock Change vs. Lock Repair Knowing whether to repair or replace your lock is essential: Repair: Ideal if mechanisms are clogged or key entry is limited.
