Which Lock Standards Actually Matter?

For securing our homes and businesses, the standards we choose matter considerably. These standards make sure our locks provide maximum protection and meet insurance requirements. We focus on specific certifications such as BS3621, TS007 3-Star, and SS312 Diamond to deliver the best security solutions.

BS3621-rated mortice deadlocks are essential for wood doors, acting as a robust back-up lock. For modern composite and UPVC doors, the TS007 3-Star Kitemark anti-snap euro cylinders are the gold standard, providing anti-snap, anti-bump, and anti-pick protection. Additionally, SS312 Diamond Sold Secure cylinders are often required for high-value properties, ensuring top-tier attack resistance.

Which High-Security Lock Suits Your Property?

Determining the right lock for your property depends on its unique characteristics and security needs.

Here is who benefits from each type of lock. If you own a higher-value detached or semi-detached home in Winchmore Hill, Southgate, or Cockfosters, the SS312 Diamond lock provides the robust security often required by insurers.

Frequently Asked Questions

What makes a lock 'high security'?

A TS007 3-Star Kitemark rating means the cylinder resists snapping, picking, bumping and drilling. A BS3621 mortice deadlock adds a second line of defence. Together they meet most UK insurer requirements.

Are high security locks worth it for a standard home?

In areas with cylinder-snapping attacks, the upgrade typically costs less than a single insurance excess. We can advise on the risk level for your specific road in Palmers Green or Southgate.

Do you charge a callout fee?

No callout fee. Fixed quote before we start.

How long does a high security upgrade take?

An anti-snap cylinder swap per door is quick; a full upgrade including mortice and cylinder on front and back doors takes longer. We confirm timing on the call.

Do you provide documentation for insurance?

Yes — an itemised invoice naming the specific lock, its BS or TS standard, and the date fitted. Accepted by all major UK home insurers.

What Do Anti-Snap, Anti-Bump and Anti-Drill Actually Stop?

Even though locks have evolved, criminals have too, which is why anti-snap, anti-bump, and anti-drill protections are vital for your home's security.

Here is why these features matter.

Anti-snap protection is essential because burglars often snap locks to gain entry. A TS007 3-Star Kitemark lock is designed to withstand such attacks, making it harder for intruders to succeed.

Anti-bump technology prevents the use of bump keys — a common tool for picking traditional locks. This feature guarantees that even skilled burglars can't easily manipulate the cylinder.

Finally, anti-drill protection involves hardened materials that resist drilling attempts, a favorite tactic among seasoned criminals.
