A friend and I were discussing Energy Efficiency Rating and Enviromental Impact (CO2) Rating as he is thinking of moving houuse. We have both seen the results as shown on estate agents literature but doing various searches on the web, we can not find out how these surveys are carried out, only that CFL's, double glazed windows add to the scores.
Anyone got any concrete knowledge on the scoring system please.
Plenty of websites say that we can go on courses for X amount of £'s.
Kindest regards,
Jim G
