How To Check If Your Locks Are British Standard Approved

To determine if the locks you currently have fitted are certified to British Standards, look out for the Kite Mark which will be stamped on them. Older locks may have a Kite Mark but these may not be in a place you can readily see and a lock may have to be removed to see the Kite Mark. It is best in this case to have a Locksmith check the locks.

If you have one of the common euro cylinder locks fitted to a current UPVC or Composite door, the Kite Mark is usually on the face of the lock near the actual key hole.

British Standard Locks And Your Insurance

It is often the case that most people look for the cheapest insurance they can find but you should be careful of what details you put in to get a cheaper policy. Do not claim you have Kite Mark certified locks if you don’t because it may invalidate your claim in the event you have a burglary.

Always ensure when filling out the insurance details, you put in the correct information, as on different insurance provider’s forms the questions can be different. If in doubt always ask a locksmith who will be able to advise you of the correct answers and determine if you do indeed have certified locks.

Mr Lock Doc can identify British Standard locks and replace your locks if they are not Kite Marked. If you would like to upgrade your locks to British Standard for better security or you’re unsure if your locks are already British Standard, call Mr Lock Doc today.

How A BS3621 Lock Affects Insurance

By examining a lock from the outside, you cannot tell how secure it is. Therefore, a lock must be assessed internally by the British Standards Institute to determine if it is produced to BS3621. A lock that is submitted for BSI testing will be tested for wear over time and will be thoroughly tested to ensure it stands up to being picked or defeated. Locks that have passed the rigorous testing and standards laid down in BS3621 will be certified and allowed to show a Kite Mark on the lock itself and any packaging it comes in. Most insurance providers now specify your locks should be certified to BS3621 and carry a Kite Mark for you to be able to get cover from them. A lock that is certified to BS3621 will also show the standards it has passed within the overall BS3621 standard.

The Different BSI Standards

There are two other main BSI standards for locks other than being certified with a BS3621 Kite Mark, these being BS8621 and BS10621. BS6321 is the most common on domestic and residential locks.

BS3621 – This standard is for Mortice and Cylinder locks where a key can be used in both sides of the lock. Usually found on back doors. This lock must be secure with the key removed and not able to be operated by someone reaching through a broken pane or letterbox.

BS8621 – This standard is for thumb turn lock types, opened from the outside by a key but can be opened from the inside using a thumb turn. Most often found in bedsits and flats. These locks are fitted to allow emergency egress without a key.

BS10621 – This standard is relevant to locks that can only be locked from the outside with a key. The lock can be opened from the inside without a key using a lever unless the lock has been prevented from being turned by using a key from the outside. These are generally fitted to front doors.
