Energy improvement potential
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 ROCK HAVEN, HIGHER LANE, DALTON, WIGAN, WN8 7RA.
- 1Room-in-roof insulationIndicative cost: £1,500 - £2,700
Insulating roof rooms will significantly reduce heat loss; this will improve levels of comfort, reduce energy use and lower fuel bills. If it has a flat ceiling insulation can usually be added above the ceiling, and sloping ceilings and walls of roof rooms can be insulated using an internal lining board. Further information about roof room insulation and details of local contractors can be obtained from the National Insulation Association (www.nationalinsulationassociation.org.uk).
- 2Cavity 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).
- 3Wind turbineIndicative cost: £15,000 - £25,000
A wind turbine provides electricity from wind energy. This electricity is used throughout the home in the same way as the electricity purchased from an energy supplier. The British Wind Energy Association has up-to-date information on suppliers of small-scale wind systems. Wind turbines are not suitable for all properties. The system’s effectiveness depends on local wind speeds and the presence of nearby obstructions, and a site survey should be undertaken by an accredited installer.
- 4Floor 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.
