Avoid. My elderly mother was approached via a telephone cal to change her energy supplier, the “gentleman” on the phone inferred that he had received information that my mother had recently changed her tariff with Edf and he was able to save some more money. My mother is a pensioner and was interested in saving money, so agreed to think about it, only to receive an email from Edf to say that they were sorry she was leaving them, and a cancellation fee, my mother then called UW to ask to end all communication. At this point she was told she outside of the cancellation window and a direct debit had been set up for payment. My mother never once handed over her bank details, yet the assistant on the phone already had these details. It was then made clear that she did not want to switch to UW. She has since received invoice from Edf, and an invoice from UW for £257 for energy supplied for 18 days! Needless to say the bank have been informed not to make this payment. I appreciate that some people who are able to easily manage their finances and who are much more tech aware, perhaps benefit from UW, however targeting vulnerable persons and setting up direct debits in a telephone call seems wrong to me. Rant over
