Although it seems obvious it is a point that is often overlooked by most people. Make sure your locks are not old, low quality or vulnerable is one way you can improve your front door security. Ensuring you have British Standard 3621 locks installed not only guarantees you have a high-quality lock on your front door, but it also means that it will be insurance approved. Millions of properties in the UK have locks installed on their property that do not conform to BS3621, if you were to have a break in with a lock like this in place, it is quite possible that your insurance company will not pay out for any damage or any goods that have been stolen.
