Cavity Wall Insulation (CWI) CWI is an inexpensive, easy-to-install process that takes around half a day and isn’t disruptive or damaging to a house. It is installed by drilling a series of small holes no bigger than a ten pence piece in the mortar between the bricks of a house, before blowing insulation through the holes until the gap or ‘cavity’ between the external and internal wall is completely filled. The hole will then be filled. There are a number of different insulating materials, but they all work in the same way to cut heat loss.
Also CWI work is carried out according to guidance laid down by the Cavity Insulation Guarantee Agency (CIGA) and workmanship and materials are covered by the independent 25 year CIGA Guarantee, to provide homeowners with reassurance and peace of mind. See
www.ciga.co.uk for details.
Tax allowances of up to £1,500 are available until 2015 for Landlords through the Landlords Energy Saving Allowance. This allowance can be used on each of the properties a landlord owns, enabling landlords to claim the costs for CWI and other insulation solutions.
If every UK household suitable for CWI installed it, 4 million tonnes of CO2 could be saved every year.
Loft Insulation
With as much as a third of heating costs escaping through the roof, loft insulation is a very effective way of reducing heating bills.
While most UK homes already have some degree of loft insulation installed, for the majority this is inadequate and should be topped up

to today’s standards of 270mm, about the height of piece of A4 paper.
The NIA recommends to avoid technical risks installing loft insulation should be carried out by professionally trained experienced NIA members. For example, a high standard can only be achieved by insulating across the top of the ceiling joists as well as between them and including the loft hatch. Pipes and tanks also need to be insulated to avoid freezing and other key considerations include ventilation to avoid condensation and safety aspects of electrical wiring and fittings.
If everyone in the UK installed 270mm loft insulation, we could save around £520 million and nearly three million tonnes of CO2 every year.
The Next Step: A large proportion of householders are unsure if they have insulation measures already installed in their home or whether it reaches the recommended standards. NIA approved installers provide free home surveys and are experienced to recommend the most suitable and practical insulation options for each individual property. They also have access to information regarding grants and subsidies to help make the cost of insulating homes even more affordable. The NIA recommends contacting one of its installer members as they are trained to the highest standards and also governed by a strict Code of Professional Practice.
