Home Security

HEET's free lock fitting and security service will make it harder for someone to break into your home. Unfortunately, our free service is very restricted at the moment. We will update this page when we are able to provide this service again.

What security measures does HEET fit?

A Crime Prevention Officer (CPO), or our own surveyor, will assess what security measures you need. Below are illustrations of some security measures that we fit.
