AVOID AT ALL COSTS. NOT WORTH THE HASSLE OR THE MONEY! Definately not worth the one star, I would put none if I could. Me and my partner were with NPower while we lived in Nottingham and the payments were extraordinary. We also once received a bill for £300+ for electric which they could not justify but just kept telling us the information that was already on the bill, not explaining why our bill went up 10x in one month! Having recently moved to a new property, I was disheartened to find our that NPower was the current supplier for that house for gas and electric and so we had to put up with them supplying our gas and electric until our new supplier had finished switching us. It turns out that they charged us nearly £70 for the 13 days that they were our supplier which is more than our monthly rate for our new supplier. With only two of us, it's been quite hard finding this extra money and their customer service are no help at all and just tell you things you already know. Please, do your research and go elsewhere. Whatever you do, DO NOT GET YOUR SUPPLY FROM NPOWER!
