Just moved from a flat that had Utility Warehouse as the supplier. During my 3 years at that address they closed my account twice without my permission (and for no reason), made me pay over the odds to get it reinstated, even sent me red letters and threatened court action whilst I was in discussions with the Chief Exec's office regarding why they had closed my account and why they were charging me so much. It appears they passed their complaints over to the credit agencies as I now have a ridiculously low credit rating despite never being in debt to anyone (including them! As I paid them, immediately once we had sorted the problems out, twice.) They are without a doubt the worst company I've ever had the misfortune to deal with, anyone thinking of moving to them - DON'T, the bills are not cheap, the customer service is appalling and the 'extras' that seem to crop up every so often are just extortionate. Example, my final bill with them for 16 days electricity... £500+. What a bargain.
