Hello,

I'm currently on the Npower SW D1 ONE tarrif which is fixed until August '09. I'm sure Npower have been overcharging me per unit on gas and electricity, but I can't find the paperwork to prove that the price they quoted me at the outset was less than what they are charging me now.

I'm sure I was quoted 5.761 pence per unit for gas but I'm not sure about electricity. I live in the South Wales area which might make a different as far as cost is concerned.

Can anyone give me some definitve info on what I should be paying per unit?

Thanks

I can't tell you what you were quoted but you can use a price comparison website, eg Moneysupermarket to find the rates for your current tariff.

The Npower One tariff is a no standing charge tariff. Possibly this features a gotcha called "primary unit seasonal weighting" which results in the winter bill being loaded. Possibly why you think you are being overcharged.
