Is there a calculator for heating costs?
Discussion
The 'standard' calculation is the one used to generate the Energy Performance Certificate that you need as part of the HIPs pack if you sell your house, which includes a basic estimate of energy consumption costs. The full calculation procedure upon which EPC's are based is called a SAP calculation and a full SAP calc give a much more detailed breakdown of the energy efficiency figures.
The software behind it is complex, though, and like all computer software, garbage in = garbage out. If you want to go down this route, you're best off paying a licenced SAP/Energy assessor, therefore - it wouldn't cost much (a typical EPC costs about £75-£100 to the man on the street, I think; we pay £26 IIRC, but then we're doing thousands a year based largely on standard house types, so we get a considerable 'bulk discount').
