Measures from this home’s official Energy Performance Certificate assessment that could raise its rating and cut running costs, specific to 149 THE CALVERS, RUNCORN, WA7 2EW.
- 1Floor insulation (solid floor)Indicative cost: £5,000 - £10,000
Insulation of a floor will significantly reduce heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. Further information about floor insulation is available from many sources including www.energysavingtrust.org.uk/northernireland/Insulation/Floor-insulation.
- 2Low energy lighting for all fixed outletsIndicative cost: £240 - £280
Replacement of traditional light bulbs with energy saving recommended ones will reduce lighting costs over the lifetime of the bulb, and they last up to 12 times longer than ordinary light bulbs. Also consider selecting low energy light fittings when redecorating; contact the Lighting Association for your nearest stockist of Domestic Energy Efficient Lighting Scheme fittings.
