Cavity wall insulation fills the gap between two thin walls, usually made of brick, with materials like mineral fibre wool, polystyrene beads, or polyurethane foam. This creates an insulating barrier that can reduce heat loss through walls by up to 35%.

Yes, it can be free for qualifying households under schemes like the Great British Insulation Scheme (GBIS). Eligibility may depend on your home’s Energy Performance Certificate (EPC) rating (D, E, F, or G) and certain income or benefit criteria.How Can I Get Cavity Wall Insulation for Free?

To qualify, homes built between 1924 and 1982 that haven’t had their cavities filled may be eligible. Factors like income, benefits, and the property’s energy efficiency rating are considered. Check your Energy Performance Certificate (EPC) for more details or contact us to see if you qualify.

After completing our online form, we’ll connect you with an approved installer who will assess your property. If your home qualifies, we’ll schedule the installation and use materials like glass fibre or mineral wool to insulate your walls. Under the GBIS, qualifying installations are free. If you don’t qualify, we still offer a free survey and a personalised quote.

Cavity wall insulation grants are available to homeowners and private tenants. Unfortunately, Local Authority or Housing Association tenants don’t qualify unless they own at least 50% of the property.

Yes, cavity wall insulation grants are free for eligible households and do not need to be repaid. Major energy providers are required to fund these installations. In most cases, the insulation is installed at no cost, although there may be instances where a contribution is needed, depending on property size and EPC rating.

Eligibility criteria under GBIS have changed. While some benefits have been removed, others have been added, including Housing Benefit and Pension Credit Savings Credit. For those on disability benefits, only means-tested benefits apply.

Yes, you may still qualify for grants to insulate solid walls, including both external and internal insulation options. Other insulation types, such as loft, Solid Wall, and underfloor, may also be eligible for grants.

If you live in a flat, insulation must be installed continuously from the ground floor to the roof. This requires consent from neighbours above and below, and they must apply individually to be assessed for grant eligibility.

By filling the air gap between walls with insulating material, cavity wall insulation reduces heat transfer and can cut heat loss by up to a third.

Any damp issues must be resolved before insulation can be installed. This would require a builder’s assistance to fix the problem first.

Typically, installation is straightforward and can be completed within three hours. For more complex cases, the time required may be longer, and you’ll be informed beforehand.

No, cavity wall insulation poses no health risks to occupants. The insulating materials, such as polystyrene beads or polyurethane foam, are safely contained within the walls and are free from health hazards.

Cavity wall insulation can significantly reduce a household’s carbon footprint. For instance, a typical detached house could save up to 1,100 kg of CO₂ emissions annually, while a mid-terrace house might reduce emissions by around 380 kg, according to Energy Saving Trust estimates.
