Energy performance certs, have been here in the UK for a number of years, Labour Gov signed up to it, cynically many would say to create a new tier of inspectors, and control! Tens of thousands were trained at their own cost (many ex-mortgage brokers (I know 2)), often estate agents. These new certified people were promised that inspections would pay up to £300 per certificate. But truth is they are as cheep as £70 for a studio (in south London). Needed for all property up for sale, and all rented homes, think they had to be renewed every 5 years, but now 10 years. Labour had planned to fine all landlords that had a low efficiency rating. Typically an inspector would turn up fill in a tick box sheet, measure the m2. Then back at office put all this info into a computer program, which then gives printed cert and rating.
I can possibly understand that for a prospective tenant or buyer, an indication of energy usage is useful, as UK is a cold wet dreary place. But Canaries - they must be joking!
