Had a call from a new customer, boiler not working. British Gas attended, not a gas problem said electrics. I attended. Work from the boiler to FCU, no power, FCU to CU, no power, CU to DNO supply terminal, no power. At this point customer tells me DNO has just changed the meter. Tweek cables in terminal and boiler works. Tighten said terminals. Boiler now working according to specs. ( Customer has been supplied with a report on what has been found). Customer called me approx 1945. I attended approx 2000. (Valentines Day)(God i'm quick, but my beloved will kill me"""""Yes Dear""""""). Boiler and electric shower working by 20.30.
