I have been with D & G for many years for various items, but my boiler which had the top cover which included a yearly service. Last week it would not work so after many phone calls backwards & forwards to D & g because the repair agent Right Gas would not answer the phone I got a visit from the repair agent. He was here 5 mins & really did not want to be here, very abrupt said there was sludge in the pipes & really needed to be replaced. Today I rang D & G for a repair & they said the Right Gas would not come out because they could not fix it. Fair enough if I have to have a new boiler at least I would get £750 towards as stated in my policy, but no D & G said I was not covered for sludge in pipes. My argument is my boiler was serviced by Ace Plumbing through D & G annually why did they not mention sludge, in fact they said it was in good condition. D & G have now suggested that I pay for someone to fix it. Never again will I go with D & G.
