British Standard
Our range of British Standard nightlatches offers premium security for external wooden doors, meeting the rigorous requirements of BS 3621 and BS 8621 standards often required by home insurance providers. Engineered to resist common attack methods, these high-security locks feature automatic deadlocking, robust 20mm anti-saw bolts, and protective cylinder pulls that guard against drilling, picking, and snapping. From standard high-security entry locks to keyless egress models designed for easy emergency escape, we stock a variety of options from leading brands like Yale, ERA, and Asec. Available in both 40mm and 60mm backsets and finished in polished brass, chrome, or satin chrome, these nightlatches deliver exceptional strength without compromising on style.
