Internal Wall Insulation (IWI) involves fixing insulating panels (such as foam, mineral wool or insulated plasterboard) directly to the inside face of your exterior walls. It creates a continuous thermal barrier, sealing out cold, reducing heat loss and improving comfort in rooms where solid or cavity walls are otherwise uninsulated.
Key Benefits of IWI
•Reduced Heating Bills
Up to 35% of heat can be lost through uninsulated walls; IWI typically slashes that loss by up to a third.
•Enhanced Comfort
Eliminates cold spots and draughts, ensuring even temperatures right to the edges of external rooms.
•Quick Installation
Work is largely internal and can usually be completed within one to two days per room, with minimal disruption.
•Improved Wall Finish
Panels can be finished with skim plaster or fitted with decorative plasterboard, giving you a fresh, modern look.
•Condensation Control
When paired with a vapour barrier and correct detailing, IWI helps prevent mould and damp.
Under the government’s ECO4 scheme (effective until 31 March 2026), larger energy suppliers fully fund home insulation measures for eligible households. Through freehousekit.co.uk, qualifying homeowners and tenants can receive complete funding—including materials, installation and a long‑term guarantee—for Internal Wall Insulation.
The UK Government’s Energy Company Obligation 4 (ECO4) scheme is designed to help lower-income and vulnerable households make energy-saving improvements—at absolutely no cost to eligible homeowners. Under ECO4, approved installers can claim the grant directly, so you pay £0 for cavity wall insulation.
To be eligible for a free ECO4 grant for IWI, you must:
•Universal Credit, Income‑based Jobseeker’s Allowance, Income Support
•Employment & Support Allowance, Pension Credit
•Child Tax Credit, Working Tax Credit, Housing Benefit
•Warm Home Discount Scheme Rebate
Note: Disability‑only benefits are not accepted under ECO4; the focus is on means‑tested support.
Complete our simple form in minutes to verify your grant potential.
An accredited assessor visits to confirm wall construction (solid or cavity), measure areas and recommend the optimal insulation system.
We manage all communications with your energy supplier to secure the full ECO4 funding.
Certified installers fit insulated panels, seal all edges and joints, add a vapour control layer, then finish with plasterboard or skim plaster.
Receive an insurance‑backed 25‑year guarantee on both materials and workmanship.

IWI panels are typically 40–60 mm thick; you’ll lose only a few centimetres of floor area, and this is often offset by the energy savings.
On average, one room (15 m² of wall) can be insulated in 1–2 days, including finishing.
Yes—tenants can qualify, but must provide landlord permission prior to installation.
You can choose skim plaster (ready for paint or wallpaper) or decorative insulated plasterboard, available in a selection of colours and profiles.
No—if you meet ECO4 criteria, there are no upfront charges, call‑out fees or co‑payments.
