With energy at the top of the political agenda, Katy Ives of Greener Homes in Hoddesdon advises how to cut bills by improving energy efficiency
Installing cavity wall insulation is one of the most cost-effective ways to improve a home’s energy efficiency. Most homes built in the past 100 years have two layers of wall, with a space between. Unfilled cavities let heat escape and can be responsible for 35 per cent of all heat lost from homes.
Installing loft insulation can slash energy bills by up to £175 a year. The recommended thickness for loft insulation is 270mm. There may be insulation in a loft, but if it falls short of the recommended amount, top it up, as 25 per cent of heat escapes through the roof.
Insulation under ground floor floorboards will save around £60 a year, and is easy to install. Simply sealing the gaps between floors and skirting boards to reduce draughts will also help.
Upgrading a heating system and controls will cut bills. If a boiler is wall mounted and is between 10 and 20-years-old, the efficiency rating is likely to be between 70 and 79 per cent. A floor mounted boiler’s efficiency could be as low as 65 per cent. With back boilers, up to 35 per cent of the gas used passes through the flue and heats the outside air! A new condensing boiler will have an efficiency rating of around 90 per cent, a saving of up to 25 per cent.
