Firstly, British Gas is totally useless if you manage multiple energy accounts, as they do not allow different supplies to be linked up to one email login. On top of this, I was told I could not discuss an account on which my company is named, and was given the incorrect email address to send a letter of authority to on four occasions by the chat team. They've sent an operative to read meters on our site who's read the wrong meter leading to bills of thousands of pounds that have taken months to remedy. They send notices demanding payment without stipulating which energy account it pertains to. Web chat team are rude and ineffective. Prices are among the highest on the market. In short, the UK's worst company, move any and all accounts you can away from them.
