Cavity Wall Insulation

Many homes built after the 1920s have cavity walls – two layers of brick with a gap between them. Without insulation, up to 35% of your home’s heat can escape through the walls, making your heating system work harder and your bills higher. At Home Efficient, we install high-performance cavity wall insulation to keep the warmth in and cut energy costs.

  • Save money on heating bills by reducing heat loss
  • Improve home comfort and eliminate cold spots
  • Quick, clean, and non-intrusive installation
  • Reduce your carbon footprint with energy savings
  • Long-lasting insulation that protects for decades

You could qualify for an ECO4 grant if:

Your property has an Energy Performance Certificate (EPC) rating of D, E, F, or G

Someone in the household is receiving income-related benefits such as:

  1. Child Tax Credit (CTC)
    Child Tax Credit is designed to assist families with children. ECO4 eligibility requires that the household income aligns with the thresholds set by the scheme.
  2. Income-Based Jobseeker’s Allowance (JSA)
    JSA is a benefit for individuals actively seeking employment. Those receiving the income-based variant of JSA automatically qualify for ECO4.
  3. Income-Related Employment and Support Allowance (ESA)
    ESA is provided to individuals unable to work due to illness or disability. ECO4 includes households with income-related ESA recipients.
  4. Pension Credit (Guarantee Credit)
    Pension Credit is a key benefit for pensioners. Those who receive the Guarantee Credit element qualify for ECO4, helping older adults in financial need improve their homes.
  5. Pension Credit (Savings Credit)
    Pensioners receiving Savings Credit are also eligible for ECO4 grants, ensuring support extends to a wide range of older residents.
  6. Universal Credit (UC)
    Universal Credit is a benefit for those on low income or out of work. ECO4 includes UC recipients, provided their income does not exceed specific thresholds.
  7. Working Tax Credit (WTC)
    Designed to support those in low-income employment, Working Tax Credit recipients qualify for ECO4 funding.
  8. Income Support
    Aimed at individuals with little or no income, Income Support qualifies households for ECO4 assistance.
  9. Housing Benefit
    Recipients of Housing Benefit, which supports housing costs for low-income individuals, are eligible under ECO4.
  10. Child Benefit (Subject to Income Thresholds)
    Child Benefit eligibility under ECO4 depends on household income and the number of children. See the table below for detailed thresholds.

Income Thresholds for Child Benefit Recipients

For households claiming Child Benefit, eligibility for ECO4 depends on meeting specific income thresholds. These thresholds vary depending on the number of children and whether the claimant is single or part of a couple.

Household TypeSingle Claimant Annual IncomeCouple Annual Income
1 Child£19,900£27,500
2 Children£24,800£32,300
3 Children£29,600£37,200
4+ Children£34,500£42,000

Households exceeding these income thresholds are not eligible for ECO4 based on Child Benefit alone, although they may qualify through other benefits.
