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 HERMITAGE CLOSE, WINWICK, WARRINGTON, WA2 8SW.

  1. 1
    Solar water heatingIndicative cost: £4,000 - £7,000

    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.

  2. 2
    Low energy lighting for all fixed outletsIndicative cost: £540 - £630

    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.

  3. 3
    Replace boiler with new condensing boilerIndicative cost: £2,200 - £3,500

    A condensing boiler is capable of much higher efficiencies than other types of boiler, meaning it will burn less fuel to heat this property. This improvement is most appropriate when the existing central heating boiler needs repair or replacement, but there may be exceptional circumstances making this impractical. Condensing boilers need a drain for the condensate which limits their location; remember this when considering remodelling the room containing the existing boiler even if the latter is to be retained for the time being (for example a kitchen makeover). It is best to obtain advice from a qualified heating engineer. Ask the engineer to explain the options.

  4. 4
    Draught proof single-glazed windowsIndicative cost: £150 - £250

    Fitting draught proofing, strips of insulation around windows and doors, will improve the comfort in the home. A contractor can be employed but draught proofing can be installed by a competent DIY enthusiast.

  5. 5
    Solar photovoltaic panels, 2.5 kWpIndicative cost: £8,000 - £10,000

    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.
