£2 million a year goes through the roof – 15 June 2009

£2 million a year goes through the roofs of North East Lincolnshire homes. That's according to Lincolnshire Energy Assessor Colin Childs from Whether you are interested in climate change or not, making your home more energy efficient could stop you wasting hundreds of pounds a year. If everyone in North East Lincolnshire topped up their loft insulation to 270mm, we would stop losing over £2 million a year between us on our heating bills. Implementing energy efficient measures in a typical 3-bedroomed semi-detached house could save up to £340 year after year - that's enough to pay for most people's mobile phone contract forever.

''Having produced hundreds of Energy Performance Certificates in the local area, we noticed that many people aren't aware just how big the savings can be compared with the costs of implementing energy-saving measures,'' explains Colin. ''In response to Government targets, energy suppliers will provide grants and offers to help and if you're aged over 70 or in receipt of certain benefits, most energy suppliers will provide loft and cavity wall insulation for free. It's important to remember that you can take up grants and offers from any energy company, regardless of whether they supply your gas and electricity.''

If your home is not insulated a quarter of your heat is lost through the roof and a third is lost through the walls. If you have no loft insulation and you install the recommended 270mm depth you could save around £205 a year on your heating bills. Professionally installed loft insulation should cost about £250 with the current subsidies, so the heating bill savings should pay back the cost in just over one year.

''If your home was built from about 1920 onwards, there's a good chance it will have cavity walls,'' says Colin. ''If those cavities have not been insulated, then cavity wall insulation is an excellent way to reduce significantly the amount of energy you need to heat your home; you could save around £160 a year on your fuel bills. With a typical installation cost of about £250, including the subsidies from the major energy suppliers, the savings should pay back the cost in just over one and a half years.''
