If you live in the UK and own or rent a property, you’ll know about EPCs. Their official name is an Energy Performance Certificate, although most people are more likely to consider them as Entirely Pointless Certificates. They were introduced by the UK Government in 2007 to give anyone buying or renting a property a guide to its energy efficiency, rating houses in much the same way as electrical appliances on a scale of A (good) to G (worst). The letter signifies how much carbon dioxide your property is likely to produce each year. EPCs also provide guidance of how you could “improve” your home, with suggested measures to reduce the CO₂ emissions, along with an indicative cost of doing it.
If you sell or rent your home you have to obtain an EPC. Currently you are not allowed to rent a property unless it has an A to E rating. There were proposals to tighten this to an A to C rating, but those proposals have been pushed back. However, many owners feel that EPCs are likely to be used as a stick to force them to make changes to meet net zero targets. Although that has been consistently denied, a recent survey by the Social Media Foundation titled “Whose energy transition is it anyway?” shows that concern is still real. That is reinforced by a new Government consultation on Reforms to the Energy Performance of Buildings Regime, which implies that EPCs may be turned into a net zero coercion tool.
