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 COBWEB COTTAGE, ALDERLEY ROAD, MOTTRAM ST ANDREW, MACCLESFIELD, SK10 4QN.

  1. 1
    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.

  2. 2
    Solar photovoltaic panels, 2.5 kWpIndicative cost: £5,000 - £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.

  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).

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 15.5–20 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.
