Making energy-saving improvements to your property could increase its value by 14% on average, and up to 38% in some parts of England, according to new research released by the Department of Energy & Climate Change (DECC).

For an average home in the country, improving its Energy Performance Certificate (EPC) from band G to E, or from band D to B, could mean adding more than £16,000 to the sale price of the property. In the North East, improved energy efficiency from band G to E could increase this value by over £25,000 and the average home in the North West could see £23,000 added to its value.

The report, which took into account over 300,000 property sales in England between 1995 and 2011, indicates that energy efficiency is now a key factor influencing the sale price of most residential dwellings in England.

“We have long known the benefits of making energy saving improvements to the home, but this study is real evidence of the huge potential rewards,” said Energy & Climate Change Minister Greg Barker.

“Not only can energy-efficient improvements help protect you against rising energy prices, but they can also add real value to your property. This Coalition is committed to helping hardworking families with the cost of living. The Green Deal is designed to do exactly that.

“The Green Deal is helping more people make these types of home improvements, reducing high upfront costs and letting people pay for some the cost through the savings on their bills. The Green Deal is a great option for anyone wanting to improve the look, feel and potentially the value of their home.”

Kevin McCloud, broadcaster and co-founder of the Grand Designs Future Living home retrofit company, said: “There are some 26 million homes in Britain, most of them about as well insulated as a rabbit hutch, and they need immediate help to be made less wasteful. This timely report tells us what we suspected all along: that people really value the well-insulated, energy-efficient home; that modest investment in measures to make our homes more comfortable, healthier and cheaper to run really pays off.

“The Green Deal is now maturing into a helpful way of financing a lot of the retrofit solutions around. Homeowners can now start to make these changes, alleviate the burden of high energy bills and improve the value of their prime asset."

Nearly half (46%) of properties in England are currently band D – but in comparison, a typical home in the West Midlands in band B is estimated to be valued at nearly £17,000 more. In the North East this could be over £19,000 – £3,000 more than the national average.

James Brooks from Brooks Estate Agents said: “For the majority of the UK we are seeing that there is a new factor dictating a home’s saleability. With fuel bills continuing to rise, buyers are becoming more and more conscious about the energy efficiency of their prospective new homes and are willing to invest more in a property now if they know it will cost them less to run in the future.

“As such, we always try to advise our customers to consider the real S.A.L.E. value – Size, Aesthetics, Location and Efficiency – when buying or selling.”
