Security Upgrade in London
Your insurance company doesn't care that your locks looked fine. They care whether they meet BS3621. We fit 5-lever British Standard deadlocks, anti-snap cylinders, and multipoint locking systems — and we'll give you the paperwork your insurer needs.
The most common upgrade we do across London is replacing 3-lever mortice locks with 5-lever BS3621 insurance-compliant deadlocks. Your insurer almost certainly requires BS3621 on every external door — and if you've got an old 3-lever lock (most Victorian conversions in London still do), your insurance could be void without you knowing it. We also handle post-burglary hardening with euro deadcases and bullet locks, anti-snap cylinder upgrades, and multipoint locking system replacements. Every job comes with a locksmith certificate for your insurer.
