I normally check that I'm still getting a competitive price every few years and as I'm on one of the special paperless/internet only tarriffs I thought I had a reasonable deal. I was somewhat gobsmacked to find that I was paying 25% over the odds when I tried one of the price comparison sites. So if you haven't changed supplier since the recent price hikes it could well be worth seeing if you can make a real saving.
