Don't know what an EPC is ? Nor did I. I could have guessed I suppose - Electrical Pulse Calibration , Ergonomic Plant Control, European Police Commission, Exploratory Petrochemical Consortium ? Nope.
It is an Energy Performance Certificate. Now I've been shamed into admitting my ignorance and even worse - discovered that ours is an F - it's added a whole new level of things to worry about. Savvy homeowners can shove in a few energy-efficient lightbulbs and bump it up a grade. But isn't that cheating ? I'd love to install a ground source heat pump, whatever that is, install some energy-efficient underfloor heating and glaze the whole house in thermally sealed bi-folds but who can afford that?
