What we cover under Anti-Snap Lock Installation
Why anti-snap matters
Standard Euro cylinders can be snapped in half with a basic grip-and-twist technique that takes 10 seconds. Once snapped, the lock opens. Lock snapping is the #1 burglary entry technique in UK homes with uPVC doors. Anti-snap cylinders are engineered to break at sacrificial points that don't compromise security.
BS TS007 1-star vs 3-star
1-star cylinders pass basic anti-snap tests but can still be defeated. 3-star cylinders (the highest rating) include anti-snap, anti-bump, anti-pick, and anti-drill features. Insurance requirements typically specify 3-star.
Brisant Ultion 3-star
Currently the most popular anti-snap cylinder in the UK. Lockdown mode activates if attacked, blocking entry even with the correct key.
Avocet ABS 3-star
Alternative to Ultion, slightly different keyway. Same 3-star rating, similar price range. Some insurers prefer this brand.
Mul-T-Lock Break Secure
Premium option with patented key system — keys cannot be copied without authorisation. Worth the extra cost for high-value properties.
Sold Secure Diamond rating
The highest UK security rating, exceeds BS TS007 3-star. We fit Sold Secure Diamond cylinders for clients with insurance requirements or high-risk locations.

Anti-Snap Locks — frequently asked questions
How much does an anti-snap lock cost?
Which cylinder you choose — Brisant Ultion, Avocet ABS, or a premium Mul-T-Lock option — sets the parts cost, so we quote on inspection and confirm the total as a fixed price before fitting.
Will my insurance require anti-snap locks?
Many major UK insurers now do, especially after a previous claim or for properties in higher-risk postcodes. Check your policy schedule — look for "BS 3621" or "BS TS007 3-star" requirements. If unsure, ask us to do a survey and confirm what your existing cylinder is rated.
How long does anti-snap cylinder fitting take?
Per door: 20–40 minutes. A whole-house upgrade (front + back + side doors) usually 60–90 minutes. We bring cylinders in stock for same-day fitting.
