Where to start... in a nutshell, my bill was estimated to be arounbd £30 pm. Having started to receive bills over £150pm, I complained to First Utility. Their investigation went on for 26 months!!! In one month, First Utility threatened me with legal action if I failed to pay £600 in 24 hrs. Eventually, following months of agony and heartache, following the intervention of the Ombudsman, my complaint led to a Check Meter fitment, proving I was correct all along. First Utility paid me back nearly £4,000 under pressure from the Ombudsman plus a very small (£150) gesture of goodwill. My advice to anyone and everyone is that yes, we all know that things go wrong, but the sign of a good company is how they respond. I would absolutely save yourself the pain and challenge and go elsewhere... AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!! AVOID!!!
