I see dead people... and they're heating the pool

Having just received a home fuel bill that would pay off the national debt of a small Central African republic, I'm all up for energy saving ideas.

We have double glazing and all the insulation we could ever need and having waded through all the price comparison sites on the weekend, once you get down to the basic idea of paying monthly by direct debit, there's little between the providers. It's the actual unit cost of electricity and gas which is the problem, not the way you pay your bills.
