I moved out of flat I had been living in for 2 years about 6 months ago and have just received a bill for £1500. I had considered that the account was closed down when I moved out. I had rung in the final meter readings and Scottish Power had actually told me that they owed me £400. At the time I thought this was strange as I had been paying an agreed amount each month by direct debit. There was a lot of back and forth as I tried to clear this up. I had been sending in the meter readings when they asked and when this came up I checked the serial number of the meter with them and they confirmed it was all correct. I still have this all written down. During the time I lived there, Scottish Power never read the meter as far as I am aware. When I called to speak to them about the bill Scottish Power said the readings had been incorrect and I had been under charged for the whole two years and had to pay the bill. The lady on the phone was very forceful. The bills were for a 2 bed small flat and would amount to £3000 over two years if I take the new bills in consideration. This seems extreme. I work full time and am not in the flat a good deal. I have looked on a few websites and seen that I should speak to Energywatch but I don't think they exist any more. Does anyone have any advice on how to deal with this?
