Agree with all reviews. I have wasted hours of my life trying to sort out simple issues. I finally managed to get an engineer to change a prepayment meter to a credit meter at a new property, but the change did not show on the account. I then wasted hours trying unsuccessfully to sort this out and also to change from (expensive) Economy 7 because we removed the old storage heaters. The customer service is atrocious, both on the telephone and on the online Chat system. They agents are not trained, and the system doesn't work. British Gas is now owned by the infamous Centrica, which is interested only in profit. If other reviews are correct, and it is difficult to switch, then I'm not surprised people are driven to the brink of suicide. A truly shocking company to be avoided like the Plague.
