Do not use british gas unless you have literally no other options. The most horrendously incompetent company I have ever encountered, which is saying something. It took 6 hours and 4 attempts to set up my account, even though my situation couldn'ty be simpler - one person renting a flat for one year who has a meter. Nearly every bill they send is wrong even when they have been given the accurate meter readings just before. And now, for no identifiable reason, they have moved my account to another server, meaning I cannot access it. I cannot access the account, close the account, provide meter readings or pay any bills. But it'll be me who has to suffer when they finally get their incompetent selves together and start chasing me for money I don't owe.
