It's not really an informative post, but I have to say I've actually made a start after months of planning and questions here...
Witten up a BNA (waiting for a builder mate to check if I guessed the fee correctly). Post off that next Tuesday or so.
Done a boat load of electrical calculations and parts research (big thanks to Adam for some offline input on this, plus all the folk at the IET forum and many others here). Formed most of a starter shopping list for the local wholesaler for the "basics" and the CU components. I'm going with Hager.
Builder mate is starting in a couple of weeks to do couple of new internal walls, opening modifications, repointing the front (I really can't face that job - I have "rustic" bricks!), screed the himalayan front room floor flat and new run of drains out the back (because we're moving everything around as part of the renovation).
After that, I'm doing everything myself, or at least that's the idea. It's a good kickstart - 7 grand to the builder, but I'm getting a lot done for that and this will really kick the project off.
Been down there today with the missus and sprogs, working under a couple of halogen site lamps (half the old wiring died, including one entire lighting circuit).
Took out some kitchen units (carefully, for resuse elsewhere) - must say that was pleasantly easy once I'd found the secret fixings. Found the gas cooker connection at last (behind a cupboard) and disconnected that.
Missus cheerfully helped (she hates this stuff). Then she had a good natter with the woman next door discussing kitchen optionssee ...
At least she has a better understanding of how much work there is to do, and how sometimes simple things take ages :-))
Long may it continue in this vein :)
Cheers
