EPC rating
What it really means
The Energy Performance Certificate grades a property from A (very efficient) to G (very wasteful). Rented homes in England generally need at least an E. A low rating means high heating bills — check the EPC before renting; it must be shown on adverts.
Context, tips & common mistakes
The Energy Performance Certificate grades a property A to G for energy efficiency, and it is the most honest document in any listing: the agent says 'cosy', the EPC says how much heat the building leaks. Rentals in England and Wales must currently meet at least band E, adverts must show the rating, and every EPC lives free on the national register — look it up before viewing and read the estimated annual heating costs inside, which forecast your winter far better than optimism.
A D or E rating on an older single-glazed terrace or a draughty conversion translates directly into serious winter bills; ask what heating system it has (gas central heating usually beats electric panel heaters on cost), when the boiler was fitted, and about loft and wall insulation. The certificate also lists recommended improvements — polite ammunition for asking a landlord about that missing insulation.
