1920s 3 Bed Terrace - Surrey.
Full rewire using the second cheapest white plastic faceplates, new pendant fittings upstairs and 18 x GU10 downlighters downstairs.
Fluorescent strip light in the loft, 2 outside power sockets, provision for 2 outside lights, new extractor fan in bathroom, hardwired smoke/heat detectors x 3.
House was totally empty (did it before we moved in) so no furniture to move or any worry about dust.
I have done all the replastering/making good and redecorating myself.
Be prepared for a total sodding mess! I can't imagine having to do it while you're living there....
