We have government backed funding available for 100% free non-repayable cavity wall insulation grants, subject to a free survey.
If your home was built between 1924 and 2010, your external walls are likely to have a gap or a cavity between them – Cavity wall insulation fills the gap – providing comfort.
Your 100% free cavity wall insulation can be installed within 14 days.
Your home will be warmer in winter and cooler in summer – saving you up to £515 per year on expensive gas and electric bills.
Our scheme works on a ‘first come first served’ basis, whilst funding is available, so we urge you to apply now to avoid disappointment.
Our installation is backed by warranties and guarantees so you can feel comfortable that you are in safe hands.
Did you know: In an un-insulated home 35% of your heat is leaked through the walls.
What is a cavity wall?
The external wall of a house is constructed of two masonry (brick or block) walls, with a cavity space of at least 50mm between, and held together by metal wall ties.
Are all houses suitable for cavity wall insulation?
No. If the house is not of traditional construction as above, it is unlikely to be suitable. The following types of property are not suitable for cavity fill: timber frame, steel frame, and random stone.
I have a Conservatory on the rear of my house. Will this affect my installation?
Any areas which prevent access to the walls such as conservatories, outhouses, garden sheds etc., may prevent that wall area from being filled. If the building area is less than 3m long then we can use tower scaffold to access the wall, but if it is too big for tower scaffold then we will exclude that area of wall and ”barrier it off” with cavity barriers.
Do I need to make any preparation for the installation?
The-drilling process can create some vibration on the external walls, so we advise that you remove any ornaments or breakables prior to drilling taking place, just to be on the safe side. If our installers need to gain access through your neighbour’s property or from their drive/garden, please ask them for permission and make sure that this is acceptable prior to installation.
Do I need to be at home for the installation?
Yes. Our installers need to check your gas appliances and make sure your walls are clear before they start installing cavity wall insulation.
My house is semi detached / terraced, will the cavity wall material go into my neighbour’s walls?
No – if the neighbour’s house is already insulated then our material will stop where it meets theirs. If it is not already insulated, our installers will fit a cavity barrier at the party wall line, usually made from bristle brush. This will prevent any trespass of material.
What type of material do you install?
We install either glass fibre or mineral wool. They allow the walls to breathe and are waterproof so no water can ”soak” through the material.
Guarantees and Warranties
A Guarantee is provided by CIGA (Cavity Insulation Guarantee Agency) – this is a 25-year guarantee and applies to the property, not the person, so you need to keep it safe with other documents for your property.
You will need this document if you sell your house.
How do I know that the walls have been filled properly?
Our installers drill out a defined pattern of holes, which ensures that the insulation fills all wall areas properly. They carry out a density check on a test box, to make sure that the machine is blowing the material at the correct level.
How long does cavity wall insulation last?
For the lifetime of the building.
Will the drilling make a mess of my walls?
The installers will fill the injection holes with mortar to match the existing finish as closely as possible. He will use a mix that closely matches the existing colour and texture. On pebbledash walls the installer will texture the mortar to try and match the pebbledash. After weathering, the holes are difficult to see.
Will my gas appliances be safe after installing cavity wall insulation?
Yes. Our installers will carry out gas spillage tests on your gas appliances both before and after the installation, to make sure that they are working efficiently and safely. If there are any problems with ventilation, they will advise you. If your appliance is over 7kw, you will require a Combustion Vent to be fitted in your wall to allow sufficient ventilation. Our surveyor will advise you of this.
Will the cavity wall insulation block my under floor vents?
No – our installers will check your vents to see if they are sleeved. If not, they will remove the vents and replace them with new ones after fitting material sleeves inside the cavity. This will prevent material from blocking the vents.
How long will it take to carry out the installation?
Most properties take around 2-3 hours, but it depends on the size of your home and whether there are any access restrictions.
How will I know if my house is suitable?
We will send a surveyor to assess your property. He will carry out a full borescope survey by drilling a hole in your wall and checking it with a camera to see it is suitable.

Cavity walls typically have full brick lengths visible and have a cavity in between the two walls where insulation can be injected.
No Cavity Wall
Solid walls typically have a combinations of bricks ends and lengths. There is no space to inject insulation into these walls.
Please note; we do not install external wall insulation.
