For changing locks across NW London, there are several compelling reasons to contemplate. We know the importance of feeling secure in your home, and sometimes a simple lock change can make all the difference.
Here are some scenarios that might resonate with you:
Understanding UK insurance standards like BS3621 and the TS007 3-Star Kitemark is essential for guaranteeing your home's security and compliance. When safeguarding your home, following these standards can make a significant difference. BS3621 is important for thief-resistant mortice deadlocks, especially for wood front doors in historic suburbs like NW4 Hendon and NW7 Mill Hill. Insurers require this as a baseline for security.
For modern composite and UPVC doors, the TS007 3-Star Kitemark sets the gold standard with its anti-snap, anti-bump, and anti-pick features. These are crucial for new-build estates in areas such as NW9 Colindale.
Here's a quick comparison of key standards:
| Standard | Application |
|---|---|
| BS3621 | Wood front doors, mortice deadlocks |
| TS007 3-Star | Composite and UPVC doors, euro cylinders |
| SS312 Diamond | High-value residences, attack-resistance |
| BS EN 1303 | Commercial doors, durability and key control |
Adhering to these guarantees security and insurance compliance.

On the day of your lock change, we guarantee a smooth and efficient process.
First, we measure the cylinder length from the center screw, which is typically 35/35, 40/35, or 40/40 mm for UPVC side-and-back doors in Hendon, Edgware, and Kingsbury. For modern composite doors in Colindale, we use longer sizes like 45/50 mm.
If your door is a 1930s wood front, we'll opt for a BS3621 mortice replacement instead.
Next, we select the appropriate anti-snap cylinder or mortice from our van's inventory. We remove the old cylinder via the center screw or replace the mortice case on wooden doors.
The new cylinder slides in securely, and we test the key turn from both sides.
Finally, we hand over three new keys and a registered restricted-key card if applicable. The entire job takes 15-25 minutes for a cylinder swap, ensuring your satisfaction.
