That sounds good, it could also help highlight where it might be worth spending money to improve heat retention.I tried a few last year before replacing all my radiators and liked the Myson Heat Loss Manager best because it lists the heat loss from each room for each element: glazing, external wall, floor. roof glazing, roof, ventilation and heat-up factor.
Of course this needs some work to enter all the details but a calculation is only as good as the data input.
