BS3621 Locks – Tested for Maximum Security

BS3621 locks are the UK benchmark for high-security mortice locks. Firstly, they are rigorously tested to ensure reliable protection against forced entry. In addition, each lock is assessed for resistance to picking, drilling, and physical attack. Furthermore, the bolt must extend at least 20mm into the door frame. Moreover, the internal mechanism is designed for long-term, repeated use. As a result, these locks meet strict British Standards Institution requirements. Therefore, they satisfy most insurance company conditions. Overall, they provide homeowners with confidence in a strong, tested security solution.

BS8621 Egress Locks – Tested for Safety and Security

BS8621 egress locks are designed to provide secure locking while allowing safe and reliable exit in an emergency. These locks are rigorously tested to ensure they meet the strict requirements for mechanical strength, durability, and operational safety. Tests include force resistance, smooth operation under repeated use, key duplication protection, and compliance with emergency escape regulations, guaranteeing that the lock functions reliably even in high-pressure situations. BS8621 egress locks are ideal for multi-door properties, residential complexes, and commercial buildings where controlled access is required without compromising emergency egress. These standards give homeowners, property managers, and insurers confidence that the locks provide both security and safe exit functionality.
