Improved EPC will boost property’s sale value

A comparison website claims that an improved rating for an Energy Performance Certificate now improves a property’s value.

This is driven by prospective buyers’ increased interest in energy efficiency.

Uswitch says that based on average house prices in the UK, a correlation has been found that properties with a higher EPC rating are more valuable.

Those with a rating of “A” or “B” have an average of around £57,000 added to their value. This is almost £10,000 more than those with a rating of “C” or worse. The difference between those rated “C” or “D” compared to “E” or “F” was a valuation of around £1,500. Homes with a “G” rating were found to have no extra value.

There is significant regional variation in the increase in house price value when upgrading the energy rating.

The South East shows the highest increase (£112,821.75), followed by London (£137,613.44), indicating that these regions may place a higher value on energy-efficient properties.

For all regions, there is an increase in house value for an improved EPC rating, with all regions apart from the East of England, South West, and West Midlands seeing at least a 10 per cent increase in house value for an A/B EPC rating.

The East of England, South West and West Midlands may have a lower percentage increase. However, this still translates to a significant increase (£22,000, £20,000, and £8,000 respectively).

Triple glazing emerges as the most lucrative upgrade, contributing an average increase of £44,770.09 to a property's value. Double glazing follows closely, offering a substantial uplift of £36,706.45. The importance of effective window insulation is evident, as single glazing shows no increase in house value.

Roof insulation, another key aspect of energy efficiency, is also found to significantly enhance property worth, with an average additional value of £25,152.64. Limited insulation, while contributing positively, exhibits a relatively modest impact at £1,552.14.

If they're so accurate how come the estate agents assessor came in with EPC F25 while a highly experienced independent assessor made it G14?
Nothing had changed between assessments. Both times it had single glazing, no heating, no insulation and the only source of hot water was an electric shower. In both assessments it scored full points for low energy lighting.
