Understanding energy performance ratings

Understanding energy performance ratings

Lynn Rafferty an Energy Performance Assessor takes us through her findings during a recent assessment on a Tepilo rented property.

I recently carried out an Energy Performance Certificate on a house in a pleasant street in a rural Buckinghamshire village, prior to its owner advertising it for rent via Tepilo. Specifically, this house is in the most northerly village in the county, right on the boundary between Bucks, Northants and Bedfordshire. There's a wide range of homes in this street - from original cottage properties right through to large new homes, only just being completed. All of them sit in a lovely street, leading up from the centre of the village towards Three Shire Wood at the top. It made me think, you don't have to live on a housing estate to have a new home, and equally you don't have to settle for an older property if you want a rural location.

Built in the 1970s, the home I inspected is somewhere in the middle. By this, I don’t just mean that it's half way up the street, and that its age is somewhere in the middle, but it’s also true about its energy efficiency. At an EPC rating of D, it's bang in the middle of the range (from A, the best, to G, the worst). Most of the older properties here will have ratings of F or G, and some of the newer ones could score as high as B. It's very unlikely that any of them will rate an A, since that would indicate a home that costs nothing to heat and light, which is really pretty rare. For its age, a score of D is pretty good, and means that it's likely to cost a lot less to heat than most properties in the street. The home is now let, the snow has gone, and a new family are enjoying the garden in this lovely spring weather. Thoughts of energy ratings aren’t foremost in our minds in the summer, but when the winter returns, they’ll feel the benefits of that D rating.

It's also good to know that a house with a rating of D is not one of those rental properties that have recently been accused of costing the Health Service £145M a year, dealing with health problems caused by homes with ratings of F and G. Friends of the Earth has recently called for a legal minimum level of energy efficiency for private rented properties, and a date, 2016, by which it would be an offence to re-let, or market for rent, properties which do not meet this standard. Poorly rated homes are linked to several health problems, including respiratory and cardiovascular conditions and rheumatoid arthritis. Not so nice, especially when it's snowing.
