House re-wire - what is the limit of DIY?
Discussion
Greetings! Loaded question, I know.
Scenario - looking at upsizing, we want a project. We've found one, and electrics will need some attention. There will also be some internal layout changes which will involve probably complete reconfig . of the loops and consumer units - rear extension and new kitchen + workshop and utility area. Upstairs there are some 15A 3-pin sockets that will obviously be deleted and replaced, but less in the way of major loop changes - probably a few new CUs added.
I know enough to know that even if I am competent, I am not considered competent by buildings control from a part P point of view, and I also know that I won't fare well trying to get a third party to sign off my work. So how far can I go?
Can I cut back the plaster, notch floorboards, run conduit and add the CU back boxes?
Can I run the cables, but leave unconnected?
Can I install (i.e. physically locate, not connect) light fittings?
What can I definitely not do?
I did consult the internet, I found a lot of firms saying don't touch it and call an electrician and a few more helpful pages where minor changes are concerned, but nothing helpful about major jobs like this. Some said I could replace like for like, some said I could add new sockets to an existing circuit, others said if I wanted to replace a plastic light switch with chrome, I'd need an electrician - which seems daft.

This is what I worry about with contractors. Having helped the old man (electronics & software engineer) wire and plumb various things in the family home I have a pretty good idea what not to do. I've now digested Part P and associated annexes and think if I involve building control from the outset and make sure they can examine each room or circuit before laying floors etc, we should be good.
Having said the house in question now has offers at 20k north of ours, so its very unlikely we'll get it.
