Frequently asked questions

Can I get free solid wall insulation in your area through the Warm Homes Plan?

Yes. Internal and external solid wall insulation are both covered under the Warm Homes Plan for eligible your area households. Solid wall homes (typically built before 1920) lose significantly more heat than cavity wall properties. Submit the eligibility form to check if your your area property and household qualify.

What is the difference between internal and external wall insulation?

External wall insulation (EWI) is fixed to the outside of the building and finished with render or cladding. It does not reduce room sizes but changes the appearance. Internal wall insulation (IWI), also called dry-lining, is fitted inside and reduces room dimensions slightly. Both achieve similar thermal improvements. The installer will recommend the best option for your your area property.

How much heat is lost through solid walls?

Uninsulated solid walls are among the largest sources of heat loss in a home, typically losing more heat than cavity walls. Insulating them can reduce heating bills by £270 to £475 per year in a typical semi-detached your area property, according to Energy Saving Trust estimates.

Who qualifies for free wall insulation under the Warm Homes Plan?

You need a qualifying means-tested benefit (Universal Credit, Pension Credit, Income Support, or similar) and an EPC rating of D, E, F or G. Your property must have uninsulated solid walls. Owner-occupiers and private tenants with landlord permission can both apply. The free survey confirms suitability.

Does external wall insulation change the look of my your area home?

External wall insulation does alter the external appearance slightly, adding around 80 to 100mm to the wall thickness and requiring a new rendered or cladded finish. Colours and textures can be chosen to suit the property. In conservation areas or listed buildings, internal insulation may be required instead.

How long does solid wall insulation take to fit?

External wall insulation on a typical your area semi-detached property takes around five to ten days, including scaffolding. Internal wall insulation is usually faster, three to five days, with some room disruption while dry-lining is fixed. Submit your form now to get started.
