I would give them zero stars if I could. Awful customer service, terrible and incompetent engineers, ni sympathy, rude, unprofessional to say the least. The phone advisor was so fake over the phone to the point of insult, engineer turned up next day to change my smart meter, spend 1 hour at my property, didn't bother checking if the appliances actually work after installation, left and I realized there was no hot water, heating or gas. Spent 2 hours at useless customer service phone, being in hold for 45 mins only to be told their office is closed for the bank holiday weekend. Had to spend 60 pounds on private engineer to fix the mistake of incompetent engineer only for another rude, unsympathetic one to turn up 4 hours later to say sorry and not even mean it. British gas is the worst energy provider ever, I will highly discourage anyone to sign up with them, even if they offer a good deal. It is worth paying extra and have the piece of mind.
