The EPC: more than an energy rating

The Energy Performance Certificate rates efficiency, but it also quietly confirms the floor area, the construction, and how many rooms a home really has.

Every home sold or let in England needs an Energy Performance Certificate. Most people glance at the A-to-G rating and move on. It's worth a closer look.

The rating

The band, A at best to G at worst, predicts running costs and, more and more, what you're allowed to do with the place. Minimum energy standards already restrict letting F and G-rated homes, and the bar keeps rising. A poor rating means high bills now and likely upgrade costs later, so work it into your offer.

The useful bits nobody reads

The certificate also records the floor area in square metres, which is the single most useful number for judging whether a price is fair. Agents sell rooms and "feel"; £ per square metre is the honest comparison. It also logs the construction, the number of habitable rooms, and often how many times the place has been extended, which is a handy cross-check against the listing.

When there isn't one

No EPC is odd, because it's legally required to market a home. Worth asking why. It can be an oversight, or it can mean the property has sat outside the normal sale-and-let cycle, which raises its own questions.
