British Gas Fixed Tariff?

A properly installed gas boiler should be a lot cheaper than electric to run for hot water and heating the house. The main thing is to insulate the house to a high standard and fix any drafts. Then only heat the main living room, wear warm clothing and have a good continental quilt.

I put cedar shingles on the gable end of the house several years ago now and am annoyed that i didn't put some insulation in while I was doing it.

Wood is not a cheap option unless you have access to a free supply, without considering the pollution aspect (if everyone in the neighbourhood had the same idea?).
