That is a tall order. For the last couple of years we have had our heating on from Dec - March inclusive, and for a maximum of three hours a day during January and Fabruary. I don't think we could cope with much less as our house is very prone to damp, and our gable end faces the harsh east winds which make it a bit chilly indoors most of the year anyway.

We have a gas fire, a wood stove and two halogen heaters that we use the rest of the time. We managed to cut our gas usage by half in the first year(the bills were exactly the bloomin same of course!).
