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 FLAT 2, 41 PARKHILL AVENUE, MANCHESTER, M8 4GZ.

  1. 1
    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.

  2. 2
    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).

  3. 3
    Cavity wall insulationIndicative cost: £500 - £1,500

    Cavity wall insulation, to fill the gap between the inner and outer layers of external walls with an insulating material, reduces heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. The insulation material is pumped into the gap through small holes that are drilled into the outer walls, and the holes are made good afterwards. As specialist machinery is used to fill the cavity, a professional installation company should carry out this work, and they should carry out a thorough survey before commencing work to ensure that this type of insulation is suitable for this home. They should also provide a guarantee for the work and handle any building control issues. Further information about cavity wall insulation and details of local installers can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).

  4. 4
    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.

  5. 5
    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).

  6. 6
    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.

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 3.5–4 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.
