In Nov, my combi boiler broke (& I had no heat or hot water for a week). Local plumber eventually fixed but must have left it turned up higher (test?) settings than usual settings (kicking myself I didn't check after). I just inputted my monthly meter readings. I'm with Scottish Gas & they are awful for comms but this is all the info I can get from my account. My house is F rated for energy efficiency but not Chatsworth. We hardly have the heating on, only shower twice a week, no tumbledryer etc but my combined bill this month was £598.36 !!! I can't pay it. I'm disabled so they can't cut me off but they can install a prepay meter. I don't know what to do. This isn't a begging thread, or even a sympathy thread really but I have 2 asd teenagers & I don't want to worry in front of them so I needed to 'say' it somewhere.
