Engaged a builder to build the new extension - and the quote included the electrics. The electrician advised that we have the old house rewired - by him - and we agreed a price. Once completed the old house needed replastering and decorating and so aside from downlighters no light fittings were put back. The replastering and decorating of the old house were scheduled to be done at the same time as the plastering and painting of the new extension. Three of the ceiling lights were put up in the new extension. Today the electrician is back to fit the new kitchen - which is part of a separate quote. He wants to be paid £25 per light to fit all the lights in the old house and 4 ceiling lights in the new extension. I feel I have already paid for this work. Am I wrong?
