In order to minimise risk it’s essential for Insurers to be able to recommend the fitting of appropriate security devices to their customers. Whilst obviously not being able to recommend specific products, the ability to recommend standards, both for the products themselves and the people specifying and fitting them is vital.a british standard is a single or number of tests a part, or assembly of parts is subject to too comply with and withstand or and uphold to too their requirements, in the case of british standard locks, the requirements are, anti-pick, anti-force, anti -drill, fire resistance and operable (in case you are locked in), all these tests are measured, so for instance one hour fire rating, the lock still operates, but this is with a measured amount of fire, not a nuclear bomb in the next room!!!, My small bit of humour comparing same with same, like how many apples is an egg worth?. Anyway the same tests are done on locks, and they either pass or fail the standard, for british standard locks

 

These locks are available with deadbolts, latches or a combination of both (when they're called sashlocks) and hook and claw bolts that are used for sliding doors. They are fitted inside a lock pocket or a mortice cut out of the door. They are very common and the chances are at least half of you will have them in one or more of your doors. They are available in two different sizes to suit the width of the door stile into which they are fitted and are operated either by a cylinder key or levered key. British standard lock fitting takes a little time 1 to 1- 1/2 hours but is worth the extra peace of mind. reccomended are yale, chubb, era, as pictured.

 

British standard locks (BS3621:2007) have a kite mark on them (see photo). Today most British standard locks are mortice locks, others are available They have a 20mm hardened bolt on them and are tested to comply to BS criteria, they are difficult to force open, drill open, pick open and other essential criteria, They come with a large frame keep adding extra security against forced entry so they are therefore recommended by insurance companies and police on all external doors.
