This is what U-Switch say about British Gas:
On 18th January 2008 British Gas announced its first price rise of the year, effective immediately.They must have been pi55ed up for the first 17 days of the year, or couldn't get staff to type out the new threatening letters before then.
I will never understand why people don't change, it is so easy both on the phone and the web:
