About British Standard Insurance Approved

The British Standard BS3621 is the probably the most common security standard for timber doors on domestic properties, most often specified for final exit doors (front and back doors) as they are most prone to attack, being the first line of defence. It is generally agreed that internal doors don’t need to meet the same level of security, although in some situations you may deem it necessary.

BS3621 is a set of security requirements the lock has to conform to so it is able to bear the coveted BS “Kite-mark”. Widely acknowledged to be the “bench mark” level of security requested by home insurance companies. Most of the features that surround the British Standard focus on attack resistance, so great news for you as a home owner and bad news for any would-be burglar.

Always check with your insurance company to see what locks and security level your household policy demands. If you had a break-in and the locks didn’t meet the stated requirement, it may void the insurance policy. The price of a few locks and some additional security measures would certainly not compare to the cost incurred during a burglary, cost of damage, cost of stolen goods, not to mention the general unrest and trauma of being a victim of home invasion! Then to top it all off the insurance company not willing to pay out. Always better to be safe than sorry!

Mortice Lock Criteria

This lock is usually fitted slightly lower than half way down the door and recessed into the edge. Operated with a mortice (Chubb style) key from both sides of door. Once locked and the key removed, even if a window is smashed it cannot be unlocked from either inside or outside.

You can check if your mortice lock is up to spec by seeing if it has the BS Kite-mark on the face plate.

Features

  • Needs to be a minimum of 5 lever
  • Levers need to have manipulation resistant features (Basically anti-pick, machined in a specific way so the levers bind on the bolt stump when picking is attempted)
  • Must have a security curtain (A collar that sits inside the round part of the keyhole, this is also another security feature to prevent picking)
  • Anti-drill plates (Case should resist drilling attack for at least 5 minutes with standard tools)
  • Hardened or reinforced bolt to resist cutting or drilling for 5 minutes
  • The bolt should protrude 20mm from lock case when locked
  • There must be at least 1000 differs on the specific series of lock (minimum of 1000 key combinations before it repeats)
  • Must have box section type keep recessed into good quality frame work

High Security Night Latch criteria

This type of lock is usually fitted higher than a mortice lock, roughly chest height. It will be surface mounted with key cylinder on outside and latch case on inside with small lever type handle or round/oval thumb turn. As this lock is BS rated it will also be key lockable from inside, so on an attempted break-in, if the window is smashed the intruder would not be able to unlock the door from inside.

The lock operates with a smaller flat rim cylinder key commonly referred to as “Yale” type, usually with serrated cuts down one side. Designed with ease of use in mind, it’s the type of lock that can be pulled behind you and will automatically lock. Now this lock being the British Standard version, it has multiple security features that make it much more secure than standard/budget night latches.

It should have the Kite-mark on the case so you can easily check if it’s up to insurance requirements.

Features

  • Automatic deadlocking and anti-slip (on closing the door a much smaller secondary latch is held in while the main latch slips into strike plate/keep causing the lock to “deadlock”, now the latch cannot be slipped by using the card technique that’s commonly seen in movies)
  • Anti-pick (Design features inside the lock to prevent manipulation, most commonly anti-pick top/driver pins)
  • Anti-drill (Made of more robust material than standard night latches to resist drilling)
  • Anti-bump (Designed to stop a certain type of manipulation/picking)
  • Minimum of 6-pin or equivalent in other designs
  • Much larger reinforced latch/bolt (To resist against cutting and drilling)
  • Armoured cylinder shroud (Brand / model specific)
  • Key lockable from inside
