External Wall Insulation Grants

If your home feels drafty, your energy bills are soaring, or your walls lack proper insulation, you may qualify for an External Wall Insulation (EWI) Grant. These government-backed schemes help homeowners and landlords improve energy efficiency, reduce heating costs, and contribute to a greener environment—often at little to no cost.

In this detailed guide, we’ll explain how external wall insulation works, the grants available, who qualifies, and how you can apply.

ECO4 Grant Eligibility

What is External Wall Insulation?

External Wall Insulation (EWI) is a highly effective way to improve your home’s thermal efficiency. The process involves fixing an insulating material to the outside walls, followed by a protective render or cladding. This not only keeps your home warmer in winter and cooler in summer but also enhances its appearance and can even increase property value.

Homes with solid walls (common in older properties) benefit the most from EWI, as they lose heat much faster than cavity walls. By adding an extra insulating layer, you can significantly reduce energy waste and enjoy a more comfortable living space year-round.

Available Grants for External Wall Insulation

Several government and energy company-funded schemes can help cover the cost of external wall insulation. The key grants include:

1. ECO4 (Energy Company Obligation Scheme)

The ECO4 scheme is one of the most popular ways to fund insulation upgrades. Major energy suppliers (such as British Gas, E.ON, and SSE) are legally required to support energy efficiency improvements for eligible households.

  • Who qualifies? Homeowners and private tenants receiving certain benefits, including:

    • Universal Credit

    • Pension Credit

    • Income-related ESA or JSA

    • Child Tax Credits

    • Working Tax Credits

  • What’s covered? Full or partial funding for insulation, including EWI.

2. Great British Insulation Scheme (ECO+)

This scheme extends support to a broader range of households, including those with lower incomes or homes that have poor energy efficiency (EPC rating D or below).

3. Local Authority Grants

Some councils offer additional funding through schemes like the Home Upgrade Grant (HUG) or Local Authority Delivery (LAD) scheme, particularly for low-income households.

Am I Eligible for an External Wall Insulation Grant?

Eligibility depends on several factors, including:

  • Your household income (priority is given to those on benefits).

  • Your home’s Energy Performance Certificate (EPC) rating (lower ratings are prioritized).

  • Your property’s wall type (solid walls are ideal candidates for EWI).

  • Your location (some areas have additional funding available).

Even if you don’t receive benefits, you may still qualify under the Great British Insulation Scheme if your home is energy inefficient.
