Why a Commercial Lock Change Is Often Urgent — Not Optional
The most common trigger we see is a staff departure — particularly one that did not end on the best of terms. Even if a former employee hands back their key, there is no guarantee that copies were not made. Under the Health and Safety at Work Act and standard insurance obligations, you have a duty to maintain secure access to your premises. Waiting to change the locks after a dismissal or a resignation where access rights are in dispute is a risk most business owners recognise only in hindsight. The same applies after a break-in attempt: even if the intruder did not get in, a compromised door or a forced lock cylinder may no longer offer the resistance your insurer expects.
Beyond staff changes, there are several situations that make a commercial lock change the logical next step: taking over a leasehold or buying out an existing business, discovering that master keys are unaccounted for, upgrading after a neighbouring premises is targeted, or simply finding that the existing locks are old, stiff, or non-compliant with your insurer's requirements. Many commercial policies in the UK specify a minimum standard — such as a BS3621 mortice deadlock on timber-framed doors, or a TS007 3-star anti-snap euro cylinder on uPVC and composite doors. We check compliance as part of every job and will flag anything that could affect a future claim.
