Started off great. Made big promises which we soon learned were lies. Offer you a good deal to sign up then your bill starts rising fast. Ours more than doubled. Told them it’s a meter error. The excuse was the smart meter wasn’t sending readings. We got a £1600 bill for underpaying. We asked for an engineer to come and change it repeatedly and they never sent one. Miraculously once the debt was paid the meter started sending perfect readings all the time without an engineer turning up and changing it ! Must be a miracle. Then when you pay your final bill with them they send you another saying you have to give them another months payment ! Makes you mad because they set your rate for the services which they tell you won’t go up. I wouldn’t recommend them to anyone. Without a doubt the worst provider I have ever had. Avoid.
