How to check your electrical system is safe

How to check your electrical system is safe

There are some tell-tale signs that your system is out of date and unsafe to work on (old-style rubber-sheathed cable, for example). But even if you live in a modern house with an electrical system that's been professionally checked and approved in the past ten years, things can still go wrong. So make sure it's safe before you begin work.

If you're in any doubt, get it checked by a qualified electrician.
