Heating & cooling profile

HotAndCold's model combines the recorded floor area, property type and EPC data, so this 161m² pre-1900 semi-detached home has a current EPC rating of F28 and mains-gas heating. HotAndCold estimates a space-heating requirement of approximately 16.0–20.5kW. The recorded EPC score sits towards the lower end of the efficiency range. Its modelled space-heating intensity per square metre is relatively high.

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 ASHVIEW, 40 TALBOT STREET, GLOSSOP, SK13 7DG.

  1. 1
    Floor insulationIndicative 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 sometimes be insulated from below which means that the floor does not need to be lifted to install the insulation. Further information about floor insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).

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

  3. 3
    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).

  4. 4
    Low energy lighting for all fixed outletsIndicative cost: £35

    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.

  5. 5
    Solar photovoltaic panels, 2.5 kWpIndicative cost: £9,000 - £14,000

    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.

  6. 6
    Increase loft insulation to 270 mmIndicative cost: £100 - £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).

  7. 7
    Increase hot water cylinder insulationIndicative cost: £15 - £30

    Increasing the thickness of existing insulation around the hot water cylinder will help to maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. An additional cylinder jacket or other suitable insulation layer can be used. The insulation should be fitted over any thermostat clamped to the cylinder. Hot water pipes from the hot water cylinder should also be insulated, using pre-formed pipe insulation of up to 50 mm thickness (or to suit the space available) for as far as they can be accessed to reduce losses in summer. All these materials can be purchased from DIY stores and installed by a competent DIY enthusiast.

Common questions

How much does a replacement boiler cost for a property like this?+

For this property we estimate an installed cost of £1,900–£3,200. This is indicative and based on the property's size, type and energy characteristics — your final price depends on equipment choice and an installer survey.

What size boiler might this property need?+

Our preliminary model estimates a heat requirement of around 16–20.5 kW. An installer confirms exact sizing on a heat-loss assessment.

How much would air conditioning cost here?+

A multi-split installation is estimated at £3,800–£5,700, depending on how many rooms you want to cool (around 3 indoor units in a typical layout).

Are these guaranteed prices?+

No — they are indicative estimates to help you understand likely costs before speaking to an installer. Your final price depends on equipment choice, installation complexity and a survey.
