So, as of the beginning of this year, it's "illegal" to do your own electrics. Well, it's not as simple as that. In fact it's not simple at all. There's a long thread on uk.d-i-y all about the subject. The consensus seems to be that you can DIY it but that you should say you didn't. The alternative is to get a buildings inspector to come and inspect your work every time you do something "significant".
Would significant include what I want to do next, which is to replace my Consumer Unit:
The Consumer Unit is the white "fuse box" on the left. It's old and crap and only has four fuses for the whole house. The lighting for both floors is on the one fuse as are the ring mains for both floors. Not good. Turn on every light in the house and it trips out.
As part of doing the kitchen I need to sort some of the electrics out and want to send ring mains to the outside shed (currently fed by an extension cable plugged in to the kitchen, which goes through a whole in the kitchen wall! and feeds the pond's pump), the garage (currently powerless) and send a wire up the kitchen wall, which will ultimately find its way to the loft (in case I ever get round to converting it). Needless to say I need more fuses than four.
Ideally I'd like to separate each floor on to its own fuse, but that really is a significant job. For now I want to keep it as it is, with room for more fuses. I've found a suitable unit with plenty of room for expansion. Now I just need to swap the units over.
The trouble is the main 100A fuse for the house. It's in the bottom right of the photo near the "service head". This part belongs to the electricity provider and the fuse is tagged to make sure it's not tampered with. I need to remove it to do the work and don't want to have to call them out to remove it. Nor do I want to pay a qualified sparky to do the job for me. Not sure what to do. My instinct is telling me to just do it and try and replace the crimp tag.
Ultimately the wiring for the whole house needs looking at anyway. I'll worry about the legalities of it all when we get round to doing that.
