Ceiling level roof insulation is generally the most cost effective of any energy efficiency upgrade made to a house. Even if you have some attic insulation you should upgrade it to today's standard of 300mm of rockwool or equivalent.
Cavity wall insulation
A cavity wall consists of two rows of brick or concrete block with a cavity or space between them. Injection of insulating product from the outside is the best method for insulating this type of wall. This is a very cost effective method of wall insulation. If your home is built using solid wall or hollow block construction methods, cavity fill insulation is not possible. You have two options: either internal wall insulation or external wall insulation.
Internal wall insulation
Internal insulation is also known as dry lining. This usually involves fixing composite insulation board containing insulation, a vapour barrier and plasterboard to the wall. The board is applied to the inside of the external walls.
External wall insulation
External insulation involves fixing insulating materials such as mineral wool or expanded polystyrene slabs to the outer surface of the wall. The insulation is then covered with a special render to provide weather resistance. A steel or fibreglass mesh is embedded to provide strength and impact resistance.
In some cases external insulation may require planning permission e.g. protected structures, architectural conservation areas or where the works result in an alteration in the front profile of the property. Planning permission is not required for internal or cavity insulation. Please check with your registered contractor or local planning authority.
Who can apply
All homeowners, including landlords, whose homes were built and occupied before 2006 can apply. Homes built from 2006 onwards should have been constructed to the 2003 Building Regulations and should not need significant upgrades. This is defined as the date your electricity meter was installed.
