Moved into house 20 years ago, and never really checked for anything unless/until there's a problem. Wonder if it's worth checking as pre-emptive move, like a mouse beginning to chew into a hidden cable or water ingress that hasn't manifested itself (yet). Or how that sort of thing would show up. Or what such a test would show anyway. Or what I can do myself e.g. with one of the "socket testers" that is available on the market (and would I understand the implications anyway as a lay person).
What would be worth checking: wiring? sockets? appliances? consumer unit?
House is 40 years old, I moved in 20 years ago and had some wiring done, and got a new consumer unit in the garage.
We do electrical checking at our place of work etc (on a comulsory basis), but should we do it at home (on a voluntary basis).
I had a new electric shower put in last year and the electrician checked the consumer unit and picked up that one of the breakers needed replacing, but nothing much else was checked. And I've had another individual breaker on the consumer unit need replacing a couple of years ago.
Any thoughts welcome.
