Recommended improvements for this property

Measures from this home’s official Energy Performance Certificate assessment that could raise its rating and cut running costs, specific to 4 HEATH ROAD, RUNCORN, WA7 5TA.

  1. 1
    Solar photovoltaic panels, 2.5 kWpIndicative cost: £3,500 - £5,500

    A solar PV system is one which converts light directly into electricity via panels placed on the roof with no waste and no emissions. This electricity is used throughout the home in the same way as the electricity purchased from an energy supplier. The British Photovoltaic Association has up-to-date information on local installers who are qualified electricians. It is best to obtain advice from a qualified electrician. Ask the electrician to explain the options.

  2. 2
    Flat roof or sloping ceiling insulationIndicative cost: £850 - £1,500

    Insulation of a flat roof or sloping ceiling will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Where the weatherproof membrane is sound and the roof construction is appropriate, suitable insulation can be placed on top of the roof membrane (inverted roof). Alternatively, where the weatherproof membrane needs to be replaced insulation can be provided under the weatherproof membrane (warm roof). Further information about roof insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).

  3. 3
    Solar water heatingIndicative cost: £4,000 - £6,000

    A solar water heating panel, usually fixed to the roof, uses the sun to pre-heat the hot water supply. This will significantly reduce the demand on the heating system to provide hot water and hence save fuel and money. The Solar Trade Association has up-to-date information on local installers.

  4. 4
    50 mm internal or external wall insulationIndicative cost: £4,000 - £14,000

    Solid wall insulation involves adding a layer of insulation to either the inside or the outside surface of the external walls, which reduces heat loss and lowers fuel bills. As it is more expensive than cavity wall insulation it is only recommended for walls without a cavity, or where for technical reasons a cavity cannot be filled. Internal insulation, known as dry-lining, is where a layer of insulation is fixed to the inside surface of external walls; this type of insulation is best applied when rooms require redecorating and can be installed by a competent DIY enthusiast. External solid wall insulation is the application of an insulant and a weather-protective finish to the outside of the wall. This may improve the look of the home, particularly where existing brickwork or rendering is poor, and will provide long-lasting weather protection. Further information can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).

  5. 5
    Floor insulation (suspended floor)Indicative cost: £800 - £1,200

    Insulation of a floor will significantly reduce heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. Suspended floors can often be insulated from below. . Further information about floor insulation is available from many sources including www.energysavingtrust.org.uk/northernireland/Insulation/Floor-insulation.
