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 8 KENDAL ROAD, BOLTON, BL1 4DS.

  1. 1
    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).

  2. 2
    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.

  3. 3
    Add additional 80 mm jacket to hot water cylinderIndicative cost: £15 - £30

    Increasing the thickness of existing insulation by adding an 80 mm cylinder jacket around the hot water cylinder will help maintain the water at the required temperature; this will reduce the amount of energy used and lower fuel bills. The jacket should be fitted over the top of the existing foam insulation and 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.

  4. 4
    Replace single glazed windows with low-E double glazingIndicative cost: £3,300 - £6,500

    Double glazing is the term given to a system where two panes of glass are made up into a sealed unit. Replacing existing single-glazed windows with double glazing will improve comfort in the home by reducing draughts and cold spots near windows. Double-glazed windows may also reduce noise, improve security and combat problems with condensation.

  5. 5
    Solar water heatingIndicative cost: £4,000 - £6,000

    A solar water heating panel, usually fixed to the roof, uses the sun to pre-heat the hot water supply. This will significantly reduce the demand on the heating system to provide hot water and hence save fuel and money. The Solar Trade Association has up-to-date information on local installers.

  6. 6
    Draught proof single-glazed windowsIndicative cost: £80 - £120

    Fitting draught proofing, strips of insulation around windows and doors, will improve the comfort in the home. A contractor can be employed but draught proofing can be installed by a competent DIY enthusiast.

  7. 7
    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).

  8. 8
    Fan assisted storage heaters and dual immersion cylinderIndicative cost: £1200 - £1600

    Modern storage heaters are less expensive to run than the direct acting, on-peak heating system in the property. A dual-rate electricity supply is required to provide the off-peak electricity that these heaters use; this is easily obtained by contacting the energy supplier. Ask for a quotation for fan-assisted heaters with automatic charge control. 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 national wiring standards, only a qualified electrician should carry out the installation. Ask a qualified electrical heating engineer to explain the options, which might also include switching to other forms of electric heating.
