Having just changed my heating from a coal-fired back boiler to a new gas boiler, which entailed a new gas supply to the house, l asked Bulb to come and fit a meter. As the cheapest option, [for me] was a "smart" gas meter, that is what l requested, and gave Bulb all the info requested, including that my new supply was medium pressure. That smart gas meter also meant my electric meter needed changing to a smart one, which l reluctantly agreed to, as it has no advantage to me. At the first attempt, an engineer came out to fit both, but was unqualified to work on med. pressure gas, so l refused him entry to change the elec meter. Second visit, a week+ later, ditto, despite phone calls to Bulb, reminding them about gas pressure, with same result. Third visit, another week+ later, the same engineer phoned first, told me he was given the same instructions again, so as he could not fit the gas meter, he wouldn't be coming. Fourth visit after more irate phonecalls, a gas board emergency engineer turned up, fitted a "dumb" meter, c/w ECV governor, and left, three and a half weeks after the initial visit, during which time l'd been without heating, and since the new system was fitted in line with the second visit, without hot water as well. As l am 71 years old and live alone, l would give no stars if l could !!!!
