Took many months to get
First Utility, who provide most flats in this building with electricity and gas, to acknowledge that there might be a problem with my gas meter, its readings or its billing. I pay more for gas in this tiny 36 m2 studio flat than we used to at the old, five times larger, four bedroom flat I used to live at before, with two or three other people in it. Eventually after over a year or so of this they issued a £400 credit, which is still running, as they might have been billing from the wrong meter. There had been another issue, a bill addressed to me, right property, wrong post-code, different account number (but it would seem to be the same meters) according to which I had never paid my bill and owed them £1300 and pence. I called them, alarmed as you would be, and they said 'sorry sir, mistake; will be rectified'. Today I have just received another bill for that second account number. It would seem that I have never paid my bill and I better pay them now those £1400 and pence or else.
If you were thinking of switching suppliers and were considering First Utility.... what can I say, I can't recommend them enough. Er, meaning really that I cannot recommend them at all! So much hassle over this! Over a year of this saga and still going...
