Heating & cooling profile
Using the recorded floor area and EPC characteristics, this 93m² 1990s detached home has a current EPC rating of D68 and mains-gas heating. HotAndCold estimates a space-heating requirement of approximately 4.5–6.0kW. This property has moderate recorded energy efficiency — neither especially poor nor especially high. Its modelled space-heating intensity per square metre is relatively low.

Energy improvement potential
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 27 GRAY CLOSE, ASPULL, WIGAN, WN2 1HU.
- 1Upgrade heating controlsIndicative cost: £450
The heating system should have a room thermostat to enable the boiler to switch off when no heat is required. A competent heating engineer should be asked to do this work. Insist that the thermostat switches off the boiler as well as the pump and that the thermostatic radiator valve is removed from any radiator in the same room as the thermostat. It is best to obtain advice from a qualified heating engineer.
- 2Solar photovoltaic panels, 2.5 kWpIndicative cost: £8,000
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.
- 3Replace boiler with new condensing boilerIndicative cost: £3,000
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.
- 4Flue gas heat recovery in conjunction with boilerIndicative cost: £900
A flue gas heat recovery system extracts heat from the boiler flue gases and transfers it to the incoming cold water so that the boiler needs to supply less heat. It is suitable for use only with a modern condensing gas boiler and should be fitted when a replacement boiler is installed.
- 5Increase loft insulation to 270 mmIndicative cost: £350
Loft insulation laid in the loft space or between roof rafters to a depth of at least 270 mm will significantly reduce heat loss through the roof; this will improve levels of comfort, reduce energy use and lower fuel bills. Insulation should not be placed below any cold water storage tank; any such tank should also be insulated on its sides and top, and there should be boarding on battens over the insulation to provide safe access between the loft hatch and the cold water tank. The insulation can be installed by professional contractors but also by a capable DIY enthusiast. Loose granules may be used instead of insulation quilt; this form of loft insulation can be blown into place and can be useful where access is difficult. The loft space must have adequate ventilation to prevent dampness; seek advice about this if unsure (particularly if installing insulation between rafters because a vapour control layer and ventilation above the insulation are required). Further information about loft insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
