RESIDENTS could make huge savings if they cut down on energy use, according to a survey.

Information released following the launch of Energy Performance Certificates and Home Information Packs shows the average four- bedroom home could save hundreds of pounds off heating, lighting, and water bills.

The certificates, which accompany houses being put on the market, use a rating from A to G to show the energy efficiency of a home and also offer advice on how the rating can be improved.

Most homes are receiving an E rating, according to the survey.

The rating could potentially rise to C if residents take action recommended in the certificates, including loft and cavity wall insulation.

A snapshot survey of energy assessors and certificates provided since the August 1 launch of the packs showed homes could typically save £180 on heating, £60 on lighting and £30 on hot water bills every year.

The top five recommendations given by assessors for improving energy efficiency have been cavity wall insulation, changing to low energylighting, putting thermostatic valves on radiators, loft insulation and double glazing.

The certificates and packs were extended to three-bedroom homes on September 10.

Communities minister Iain Wright said: "Families buying four-bedroom homes are getting clear information which shows how they can save hundreds of pounds on their fuel bills and cut carbon emissions too.

"It is important this should be available for people buying three-bedroom homes as well."

A spokesman for WWF (World Wide Fund for Nature) said: "We hope the Government will apply the same energy rating process to all homes being put on the market by the end of the year.

"If all home owners were given sufficient incentive to lower the carbon emissions from their homes, the UK's carbon footprint would reduce significantly."

Green grants of £100 to £300 for energy-saving improvements such as loft insulation are available to many homeowners from energy suppliers.
