FAQs
A cavity wall consists of two thin walls, usually made of brick, with a gap or cavity between them. An insulation scheme can use materials like mineral fibre wool, polystyrene granules, beads, or polyurethane foam to fill this gap. This creates an effective insulating barrier that can reduce heat loss through the walls by up to 35%.
Yes, it can be free for qualifying households under government schemes such as the Energy Companies Obligation (ECO). You may qualify if your home falls into the right EPC rating (D, E, F, or G) and you meet certain income or benefit-related criteria.
To get cavity wall insulation for free, your home must meet specific criteria. Typically, homes built between 1924 and 1982 that haven’t had their cavities filled may qualify. Eligibility often depends on your income, benefits, or the property’s energy efficiency rating. If you’re unsure, you can check the Energy Performance Certificate for your home in England to see if cavity wall insulation is recommended or already installed.
Once you complete the online form, we will connect you with an approved installer who will assess if your property is suitable for cavity wall insulation grants. If your home has unfilled cavity walls, we will use materials like glass fibre or mineral wool to insulate them and retain more heat. We’ll schedule the installation, and if you qualify for the Energy Company Obligation grant, you won’t have to pay. Even if you don’t qualify, we offer a free survey and a customized quote.
Yes, it is possible to get free loft insulation without being on benefits. Under the ECO4 scheme, low-income households with an annual income of £31,000 or less may still qualify for free insulation, even if they do not receive benefits.
Government cavity wall insulation grants are available to those who own their property or rent it from a private landlord. Unfortunately, they are not available to Local Authority or Housing Association tenants unless they own 50% or more of the property.
Some benefits have been removed from the qualification criteria for ECO4 (listed above). For those in receipt of disablement benefits, only means-tested benefits apply. However, several benefits have been added in ECO4 including Housing Benefit and Pension Credit Savings Credit.
