As a single occupant who works at 3 times a week, I'm an extremely low user. I've used a smart meter since moving to the property. I don't use gas, bit still pay a standing charge. My monthly 'smart meter' bill was around £47. I had an email saying this has increased to £162 a month. Customer services said it could be a fault with the smart meter and is based on the previous owners??? I was a advised to cancel the direct debit and pay for each bill monthly. After doing so, I received and email saying "not your direct debit has been cancelled you'll be paying higher prices". I find the whole service very unprofessional and well most definitely be changing suppliers at the earliest convenience. I would recommend this energy provider to my worst enemy. Just read the other reviews and decide for yourself. Who's like the plaque.
