Why Choose Our Deadlocks?
Certified Maximum Security Earn the trust of insurers and law enforcement: our deadlocks meet the stringent BS 3621 British Standard, the gold standard for external door security.
Built to Withstand Intrusion Engineered with laminated steel deadbolts for a formidable 20 mm throw, hardened casing to resist drilling, and a 5‑lever mechanism to deter picking.
Straightforward Security Upgrade Ideal for boosting protection in new builds or replacing outdated 2- or 3-lever locks—no handles needed, making it a clear-cut enhancement for entry doors.
Complete Installation Kit Included Each deadlock package contains everything you need—lock case, faceplate, box striker, two keys, keyhole escutcheons (one covered), screws, and fitting instructions—for seamless installation.
Who It's Ideal For
Homeowners seeking top-tier external door security.
Anyone upgrading from standard lever locks to an insurance-compliant solution.
New builds or renovations requiring a quick, reliable security update.
A 5-lever mortice deadlock is a key-only lock fitted into a slot cut in a timber door's edge, throwing a solid steel deadbolt into the frame. Five levers must all lift correctly before the bolt moves, giving strong pick resistance. It's the classic second lock on wooden front and back doors.
Look for BS3621 — the British Standard most home insurers require for locks on external timber doors. A BS3621 deadlock carries the Kitemark on its faceplate and has passed drill, pick and force testing. Fitting one typically satisfies the 'five lever mortice deadlock to BS3621' clause in policy wording.
A deadlock has only a key-operated deadbolt — no handles. A sashlock adds a sprung latch operated by handles above the keyhole, letting the door close and open normally between lockings. Deadlocks suit doors with a separate nightlatch; sashlocks suit doors that need everyday handle operation.
No — mortice locks are for timber doors only. uPVC and composite doors use euro cylinder multipoint locking instead; there's no solid material to cut a mortice into. To upgrade a uPVC door, fit a TS007 3-Star cylinder and consider 2-star security handles.
Open the door and check the metal faceplate on the edge: BS3621 locks carry the British Standard Kitemark and the standard number stamped into the plate. No markings means it's almost certainly not rated — worth upgrading, since insurers can query unrated locks after a claim.
