Had central heating system fitted with mira shower needed it done quickly so used british gas my wife is shielding from coronavirus as she has bad asthma. Where do I start after looking at reviews wish I never used them 1;the man who quoted was british gas new we had no water or heating and knew we needed it done asap but overpriced job for a combi boiler five radiators all piping and mira shower 6500 A contractor came and fitted all this left the place In a mess fitted carpets all left up floor boards not fitted back properly, he caused a water leak by hitting nail in pipe Shower dont work the control unit looks like a 5.99 special from b and m. Pipe work outside all marked Kitchen ceiling has water damage I was working away at the time so he had a easy target my 67 year old wife to fob off Phoned british gas told them I was promised at British gas man to fit not some Mickey mouse contractor Now I'm stuck with a shower dont work and the house in a total mess they will take 72 hours to phone me and upto 8 weeks to come out What a shambles wont use British gas again.
