I know a good electrican if you need one mate? 8)
I wouldnt mind starting again with a house and doing it from top to bottom, it would just be hard with the little dude at the moment.
The place we have brought, we have payed £1k less than they payed for it 2 years ago, and in those 2 years they knocked the kitchen through to form a big open plan kitchen/dining room and installed a brand new kitchen, consevatory on the back and complete new bathroom. From what i can gather, they had an unexpected 3rd child and needed a 4 bed house.
So while we have payed more than we were going to, we have had roughly £10k's worth of stuff done to it for nothing. Nothing to do, just move straight in.
Result!!!
