CALL FOR IMMEDIATE HELPHow Our Insurance-Approved Lock Upgrades Works
Simple, transparent process — we keep you informed every step of the way.
Call us with your policy details if you have them. We'll identify what upgrades are needed and give you a clear, fixed price.
For timber doors, the standard requirement is typically a BS3621 five-lever mortice deadlock. For uPVC and composite doors, a BS8621 anti-snap cylinder is usually required. We stock both.
Your locksmith arrives and confirms the current locks against the required specification before starting any work.
Compliant locks are fitted professionally, and we confirm correct installation against the British Standard before completing the job.
We issue you with a written record of the locks fitted, including make, model, and BS certification for your insurer.

FAQs — Insurance-Approved Lock Upgrades
Straight answers to the questions we hear most often.
Check your policy documents — look for wording about 'British Standard locks', 'BS3621', or 'five-lever mortice deadlock'. If your locks don't have the BS Kitemark on them, there's a good chance they don't comply. Call us and we can check for you.
BS3621 five-lever mortice deadlocks start from £109 supply and fit. BS8621 anti-snap cylinders are typically slightly less expensive. We confirm the exact price over the phone before coming out.
Yes — every insurance-approved lock upgrade comes with a written record showing the make, model, and British Standard certification of every lock fitted. This is suitable for submitting to your insurer.
We'll tell you — and we won't charge you for work that doesn't need doing. If your locks are already compliant, we can still provide written confirmation of what's fitted if you need it for your insurer.
Yes — anti-snap protection is a core feature of any BS8621-compliant cylinder, not an optional extra. All BS8621 cylinders we supply also include anti-pick and anti-drill protection.
