Cavity Wall Insulation Grant Application Form
How can I tell if my home has cavity walls?
Cavity Wall Insulation Grants are only available for homes which were constructed with external cavity walls which were not insulated at the time of construction and have not been insulated since.
Properties built before 1926 were normally constructed with solid walls which cannot be insulated. Properties built after 1st January 1983 were required under Building Regulations to have insulated cavity walls.
Properties which cannot have cavity wall insulation installed include those with solid walls, either brick or stone, timber framed properties and those with metal cladding.
Cavity Wall Insulation Grants – Cavity Walls
Cavity walls are constructed with all of the bricks laid ‘end to end’ in a regular pattern. There is a gap, or cavity, between the external and internal skins of brickwork.
Cavity Wall Insulation Grants – Solid Walls
Solid walls have some brick courses laid ‘end to end’ and some with the bricks ‘through the wall’ so that you see the ends of the bricks. There is no cavity to insulate.
What if I can't see the brickwork?
If the external brickwork on your home has been covered with render or pebble dash, you can tell whether you have cavity walls by measuring the width of the wall from outside to inside.
This will normally be easiest at a door and if the external wall is more than 260 mm thick then it probably has a cavity. The 260 mm would normally be made up of 100 mm external brick wall, 60 mm cavity and 100 mm internal block work. The external and internal skins are held together with stainless steel wall ties.
If your external walls are less than 260 mm thick or built with stone, your home’s external walls are probably solid.
How can I tell if my home has had cavity wall insulation installed after it was built?
Cavity Wall Insulation Grants are not available for householders whose homes have had cavity wall insulation installed since it was built.
If cavity wall insulation has been retro-fitted to your home you will normally see tell-tale drill holes where the insulation was pumped into the cavity.
These holes should have been filled with mortar once the job has been completed.
You can also check the EPC (Energy Performance Certificate) for your home HERE for England and Wales and HERE for Scotland to see whether it recommends that cavity wall insulation has been installed or not.
In addition to Cavity Wall Insulation Grants, you may also qualify for a Loft Insulation Grant.

Cavity Wall Insulation Grants FAQs
Cavity Wall Insulation Grants – Costs and Savings
If your home has external cavity walls but with no cavity wall insulation installed you could be losing up to 35% of the heat you generate through the uninsulated walls.
According to the Energy Saving Trust, for a four bedroom detached house you could save up to £275 per year by installing cavity wall insulation.
This saving is based on a home which has gas central heating so if your heating system uses oil, LPG, coal or electricity (which are all more expensive than gas) you could save even more each year.
Cavity Wall Insulation Grants – Free Survey
We would need to arrange to survey your home to confirm that it does have external cavity walls and that they are not insulated.
A simple test with a boroscope ( a camera inserted into the cavity) will tell whether your wall has cavity wall insulation.
The surveyor will also check the width of the cavity (as narrow cavities should not be insulated) and will check for damp (as this could be worse if the cavity is filled with insulation).

Cavity Wall Insulation Grants – Types of Property
All types of property are eligible for Cavity Wall Insulation Grants but the amount of the grant will differ according to the property type, size, number of bedrooms and current hearing system.
The Affordable Warmth Scheme has two main aims: to help householders reduce their heating bills and to reduce carbon emissions.
The greater the long term savings in carbon emissions which is achieved by installing cavity wall insulation, the greater the grant. This favours larger homes over smaller ones, those with more bedrooms and those with off gas heating systems.
We will not be able to advise householders of the amount of their Cavity Wall Insulation Grants until after the Free Survey.
