Don’t use this company, terrible service for the 2 years since I moved into this property and they were the existing providers. Bill monthly, if you don’t pay within a couple of day you get increasing demanding letters every other day then sent to the debt collector within the week. When I eventually got round to switching they sent me a final ESTIMATED bill, which turned out to be £300 over estimated, again referred me to a debt collector and when I tried to phone to supply company with final reading and adjusted bill was spoken to aggressively and rudely, demanding my date of birth (never needed it to take my money for 2 years), offensively patronising all round terrible. That’s before I get on to the cost. More expensive than any other provider. Absolutely appalling, avoid at all cost
