UW - would be giving them 0 stars if I could. Worst company ever, on hold for over 2 hours, been trying to contact them about an overcharged bill from July to August, cant get through to anyone and can if you can you get passed from pillar to post without any help. I am glad I moved to Octopus in August just to get away from them but they have sent me bailiff letters for the money I owe them. Ended up going to energy advice Scotland as I cant contact anyone by phone and the email I am getting all say the same thing, no one is trying to sort this out. Energy advice Scotland have asked UW to put a hold on the bailiff letters as this is under investigation and asked them send me a deadlock letter, no response as yet!!! This case will be referred to the Energy Ombudsman if it is not resolved. AVOID UW AT ALL COSTS, unless you really want the stress.
