BS3621 Locks in Hayes, Greater London
Need bs3621 locks in Hayes? First Line Locksmiths attends UB3, UB4 with an average response of 20-30 minutes, 24 hours a day. Engineers are positioned across West Drayton, Yiewsley, Harlington so we reach the streets around Lombardy Retail Park and Stockley Park faster than centralised national chains.
BS3621 is the British Standard for thief-resistant mortice locks and the specification almost every UK home insurer requires on external timber doors. We supply and fit BS3621 5-lever mortice deadlocks and sashlocks from Union, ERA, Yale, Chubb and Mul-T-Lock — all Kitemarked, all insurance-approved, all fitted with a 12-month parts and labour guarantee. If your existing lock isn't BS3621 stamped, your insurance claim could be refused after a burglary; we'll tell you on the call whether you're compliant or not.
With the Elizabeth Line driving heavy new-build development around Hayes & Harlington station alongside large estates of 1950s council-built ex-local-authority stock, our engineers carry both modern multipoint mechanisms and older Era and Yale rim locks on every van.
