Just as we're starting to head out of a long (really long!) winter, I think I need to review my heating etc in the house. My house is very draughty and absolutely not energy efficient. I am dreading the next bill which will tell me exactly what it has cost to keep me nice and warm. Other than double glazing the windows (which I can't afford) and insulating the roof (which we've done) what other ways are there that are worth looking into to economise on the heating bills. Are solar panels a complete nonsense on a small house in a city or not?
