Lock Grades and Security Ratings Explained for Manchester
BS3621, TS007, Sold Secure — lock ratings can be confusing. Here's a plain English guide to what they mean for your Manchester home.
When shopping for locks or talking to a locksmith in Manchester, you'll encounter various security ratings and standards. Understanding these helps you make informed decisions about your home security.
BS3621 — The Insurance Standard
BS3621 is the British Standard for thief-resistant locks. This is the standard most insurance companies in Manchester require for external doors. A BS3621 lock has been independently tested for resistance to:- Picking- Drilling- Cutting- Forcing
Look for the BSI Kitemark on the lock body. Without this mark, it hasn't been independently tested.
TS007 — The Euro Cylinder Standard
TS007 specifically relates to euro cylinders used in UPVC and composite doors. It has a star rating system:- 1-star: Basic resistance to attack- 2-star: Not commonly used- 3-star: The highest rating, achieved either through a 3-star cylinder alone or a 1-star cylinder plus a 2-star handle/escutcheon
For Manchester homes with UPVC or composite doors, we recommend a TS007 3-star solution.
Sold Secure
Sold Secure is an independent testing house that rates security products:- Bronze: Basic security- Silver: Intermediate- Gold: High security- Diamond: Maximum security
SS312 Diamond
This is the pinnacle of euro cylinder security ratings. Cylinders like the Ultion and ABS Master carry this rating. They've passed the most rigorous attack tests available.
What does your Manchester insurance require?
Most policies require BS3621 locks on wooden doors and recommend TS007 3-star rated euro cylinders on UPVC and composite doors. Check your policy wording or call your insurer for specifics.
