I had the whole place rewired (a year ago) and so far I've 'made good' the sockets and switches in three of the bedrooms, the extension, hall and landing.
I have three rooms left to do. I've been redecorating instead - but very, very slowly. I'm rarely in a patient enough mood to do things (except walking the dog, which I love).
Sometimes, I just gather all the gear needed (tools, materials, vacuum, extension lead, work light, radio etc.) in the place to start work. The next day, I'm more likely to actually begin. I have two or three projects on the go, so that when I really can't face going back to one, I might do another!
Obviously, progress is painfully slow!
