Here is a great website which will help you identify whether your locks comply with the British Standards https://www.locksmiths.co.uk/faq/what-are-bs3621-british-standard-locks/
Qualified & Approved Lock and Safe Providers.
We and our subcontractors are fully qualified to the latest standards to supply and install all the locks we provide. As NSI Gold approved installers, we fit, commission and maintain locks to the highest possible industry standard.
Domestic Locks
Domestic locks are often the only line of defence against break-ins and thefts. Make sure your locks work as hard as possible to by choosing the right locks for your property. We can also provide secondary security measures such as door chains and viewers for added reassurance.
As well as traditional locks, we supply electrical locks allowing for keyless entry – for example using a keypad.
Commercial Locks
Ensure extra protection for stock and premises with industrial strength locks. Because commercial locks are made from high endurance materials, they are especially hardwearing.
In addition to traditional locks, you can choose keyless entry systems to minimise the number of keyholders and the associated cost.
Locks for use in the public sector
Choosing locks for use in the public sector can present a dilemma – how to ensure security while allowing staff to enter buildings as necessary. We provide a full range of locks, which when coupled with access control systems keep premises, equipment and people reliably secure.
As well as traditional locks and padlocks, we supply keypad, fob and biometric door entry systems which can provide greater transparency about who has entered buildings and when.
