Cavity Wall Insulation

A Smarter Way to Keep Heat Inside Your Home

If your home has unfilled cavity walls, a large amount of heat can escape through the external walls. Cavity wall insulation helps slow this heat loss and keeps rooms warmer for longer.

Commercial Improvements Ltd provides professional cavity wall insulation services for homeowners, landlords and funded retrofit programmes. Our trained team checks whether your walls are suitable before any work starts, helping to reduce risks linked to damp, poor wall condition or unsuitable exposure.

Once the property is confirmed as suitable, insulation is installed through small drilled holes in the external wall. These holes are filled afterwards to closely match the existing finish, leaving a clean and tidy result.

Key Benefits

Why Install Cavity Wall Insulation?

Cavity wall insulation is one of the most effective ways to improve comfort and reduce unnecessary heat loss in suitable homes.

Reduced Heat Loss
Filling the cavity helps reduce the amount of heat escaping through the external walls, keeping more warmth inside the property.
Lower Energy Use
When the home holds heat better, the heating system may not need to work as hard to maintain a comfortable temperature.
Warmer Rooms
Cavity wall insulation can help reduce cold walls and improve the overall comfort of living spaces during colder months.
Improved EPC Performance
Wall insulation can support better energy performance by improving the building fabric and reducing heat demand.
Minimal Disruption
Most installations are completed from outside the property, with small drill holes filled after the insulation is installed.
Grant Support Available
Where funding is available, we can check your eligibility and advise whether cavity wall insulation may be covered under a suitable scheme.

Is Cavity Wall Insulation Right for Your Home?

Cavity wall insulation is highly effective when installed in the right property. Before recommending the measure, we assess the building condition, exposure, wall type and any signs of moisture risk.

Suitable Wall Construction
We check that the property has cavity walls with a suitable cavity width and construction type before any installation is proposed.
Wall Condition Checked
Defects such as damaged brickwork, cracked render or faulty rainwater goods should be addressed before insulation is installed.
Damp Risk Considered
We look for signs of existing damp or water penetration to make sure the measure does not create future moisture problems.
Ventilation Reviewed
Good ventilation is important in an insulated home, so we consider background ventilation and any condensation concerns during the survey.
