If you are claiming certain benefits and use British Gas for your gas or electricity, you can go onto their Essentials Tarrif, which is at least 10% cheaper than normal, it is also capped until 2009.

I found out about this yesterday as I was looking to cap my fuel, you just ring up and they switch you over on the phone there and then.

You can even get your home insulated to free

It's a freephone number too, just have your reference numbers handy
