Not much to comment on here other than it’s better to paint the walls and ceiling before putting the final floor covering down. Common sense really.
I painted the walls and ceiling with the same very slightly off white colour.
Here be pictures of painted walls.
Second fix electrics went without a hitch. At the last minute I added a separate, dedicated earth wire from each of the clean ring sockets back to the board. I did this in a vague attempt to minimise earth loops. My understanding is that this is close to a star earth, although I’d welcome comment from someone who knows more about this. I hid it under the plasterboard and stuck it down where it ran across the base of the door way.
Once we were done I wanted to know what the resistance was on the earth. The maximum acceptable for Building regs is 50Ohms. I asked a tame sparky with the right gadget to come and check my wiring and earth ratings. Turns out I had achieved 4.85 Ohms. Job well done.
