Round 2 should be looking for providers that will do it cheaper.
I am not a British Gas lover so they would not be on my list.
I heard in the news about a fortnight ago that one of the company's that provide Gas and Electric profits were up 100% since last year.
You have to ask why the government allows it.
All you have to do is go online and search and make sure you know or have a good idea as to what you have been charged for the last year or what energy that you have used in that time.
Some of the providers will charge you for leaving unless you have complained that you were not happy with the price increase and you wanted to leave.
The provider that I am with does not charge but I would take a bet that yours would.
