If your home was built after 1920, its external walls will probably be made of 2 layers of brick or block with a gap or cavity between them. With uninsulated cavity walls, around one third of the heat escapes meaning that more fuel is required to keep it at a comfortable temperature. In a typical 3 bedroom semi-detached house with gas central heating, you can save up to around £275 a year on your heating bills by insulating your cavity walls.*

6 million homes in Britain now have cavity wall insulation. The Government regards it as the most cost effective energy saving measure that most people can carry out on their homes.

How does Cavity Wall InsulationWork?

Air acts as a natural insulator — in other words, heat does not travel through air very easily. Most people know that the best way to keep your body warm is to wear several layers of clothing. This is because the layers trap air in between them and keep it still. Cavity wall insulation works in a very similar way. The wool-like material used to insulate your home traps air in between its fibres to create an ‘air matrix’. This is why cavity wall insulation is much more effective at retaining heat than empty cavity walls.

Cavity wall construction details. Cavity walls have an even brick pattern, solid walls have an alternating pattern.

What if your walls are rendered or the brickwork isn’t visible for some other reason? In that case, take a look at the thickness of your exterior walls. You can do this easily by looking at a doorway or a window. If it is more than 260mm thick, chances are you have cavity walls.

Finally, how do you know if a previous owner hasn’t already had the cavity walls filled? You can actually tell by taking a close look at your external walls. If cavity wall insulation has already been installed, you will notice a few small drill holes in the mortar between the bricks – they will have been filled and won’t be very obvious, but look closely and you will see them. This is where the installers will have blown the insulation into the walls.

If your cavity walls have already been insulated, you will notice a few small holes in your external walls which will have been filled.

Still not sure? A trained Energysave inspector can inspect your walls for free and let you know if they are suitable. You can book your survey if your Epc has not been booked via our office

If it turns out you have solid walls, or for some other reason your house is not suitable for CWI, then you may want to consider solid wall insulation instead.

Do you guarantee the work chosen by the company insulating our property

Yes, any company that carry out the free cavity wall insulation on behalf of Energysave Nationwide will be on the ciga guarantee listing

What is ciga guarantee?

The Cavity Insulation Guarantee Agency is an independent body that provides 25 year guarantees for Cavity Wall Insulation fitted by registered installers in the UK and Channel islands. The standard Guarantee covers traditionally constructed residential property, although a CIGA Commercial Guarantee is also available to owners of qualifying non residential property.

The Government regards cavity wall insulation as the most effective energy savings measure that most people can carry out on their homes and a major contributor to reducing emissions of carbon dioxide, the main greenhouse gas. The Cavity Insulation Guarantee Agency was established in 1995 after consultation with the Government’s Energy, Environment and Waste Directorate (a division of DETR) to provide householders with an independent, uniform and dependable guarantee covering defects in materials and workmanship.CAV5

Independent research carried out for the Department of the Environment, Transport and the Regions (DETR) has confirmed that cavity wall insulation is a very reliable process. Problems are therefore extremely rare, but if they do occur, CIGA has the expertise to ensure that they are swiftly rectified.

CIGA also operates and administers the Cavity Wall Insulation Self Certification scheme (CWISC) in association with the British Board of Agrément. The scheme provides homeowners with the comfort of knowing that work by registered contractors complies with the requirements of the Building regulations.

Further details and a list of CIGA members who are also registered under CWISC is available on the dedicated CWISC website. In the unlikely event that you are dissatisfied with the service provided by CIGA a copy of our complaints procedure is available upon request.

Insulation Services

Before installation begins, a CIGA registered installer will carry out a pre-installation assessment to ensure that the property is suitable for Cavity Wall Insulation. The installation of the insulation will then be completed at a mutually convenient time according to stringent technical standards laid down by CIGA.

Once the work is finished and final payment has been received the installer will apply to CIGA for a Guarantee, and a certificate will be sent directly to you. The Guarantee should be kept safely, as it may need to be produced in the event of a claim or if you sell the property, since the Guarantee is also available to subsequent owners of the property.
