Heating & cooling profile

HotAndCold's model combines the recorded floor area, property type and EPC data, so this 51m² 1970s flat has a current EPC rating of D57 and its recorded heating. HotAndCold estimates a space-heating requirement of approximately 2.5–3.5kW. Its current energy rating indicates moderate energy efficiency. The estimated heat demand per square metre is towards the lower end.

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 SOUTHDOWN CLOSE, HEATON NORRIS, STOCKPORT, SK4 1LD.

  1. 1
    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.

  2. 2
    High heat retention storage heaters and dual immersion cylinderIndicative cost: £800 - £1,200

    Modern storage heaters have better insulation and are easier to control than the older type in the property. Ask for a quotation for new, high heat retention heaters with automatic charge and output controls. A dual-immersion cylinder, which can be installed at the same time, will provide cheaper hot water than the system currently installed. As installations should be in accordance with the current regulations covering electrical wiring, only a qualified electrician should carry out the installation. It is best to obtain advice from a qualified heating engineer. Ask the engineer to explain

  3. 3
    Floor insulation (solid floor)Indicative cost: £4,000 - £6,000

    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.

  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
    Low energy lighting for all fixed outletsIndicative cost: £15

    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.
