British gas are absolutely to be avoided! They are crooks. They lie, they cheat , they steal. I live in a tiny one bedroom apartment. I use about 13 units of gas a month, this would come to about £40 a month - give or take. Well not to British gas who billed me £1800 for two months use of gas and £280 for electricity on the very same day! Stating that I'd used over 1000 units of gas. Look if I owned a seven bedroom property, it still wouldn't reach that copious amount. I'd like to say that it was an isolated case but no, I am met regularly with absolutely absurd bills ranging from £720 to £900 for one months use! Oh and they just take it from your bank account without telling you. You will of corse be on the phone for three hours with them being passed around an Egyptian call centre only to be lied to that the problem is solved, be told to contact your bank to get a refund, so I do and then four days later British gas pounce again and take back the money that they told you to recover, and around and around this goes. Do yourself a favour and just boycot them at all costs. Within two years of being with them I have been charged over £3000 with British gas getting debt recovery involved for a bill I didn't even run up. Absolute con artists.
