Billed for energy for 7 months at a property I moved out of last march. Whilst the new tenants where also being billed by UW. I have been trying to get over £1500 back from them since october My april bill has just arrived and they are now trying to get £256 from me for last aprils bill, where I have already paid more than £400 for that month. Even though the house was empty from the !0th March. How could i have used £650 worth of energy in 10 days? They will happily take the £256 from the money they already have of mine. I will be cancelling all the services i have with UW. Do not trust the company.
