The Great British Insulation Scheme (Eco plus)

The Great British Insulation Scheme is a new government energy efficiency scheme (formerly known as ECO plus) that will be administered by Ofgem. It is designed to deliver improvements to the least energy-efficient homes in Great Britain to tackle fuel poverty and help reduce energy bills.

What is the Great British Insulation Scheme?

The Great British Insulation Scheme(Eco plus) is a government initiative in the United Kingdom designed to improve energy efficiency in residential properties through enhanced insulation. The primary aim of this scheme is to reduce energy consumption in homes, which in turn helps in lowering heating costs for residents and decreasing overall carbon emissions.

By providing financial assistance or grants, the scheme targets homeowners and tenants, with a particular focus on aiding low-income households.The program is set to commence in Summer 2023 and will continue until March 2026, with the government anticipating that it will result in annual savings of approximately £310 for households.

What are the main features of the Great British Insulation Scheme?

The Great British Insulation Scheme offers several key features aimed at improving energy efficiency and reducing costs for households.

Insulation Grants : The scheme provides substantial grants for insulation upgrades, with grants covering up to 75% of the installation cost. For example, a typical insulation project costing £1,000 could receive a government subsidy of £750.

Energy Savings: By improving insulation, the program aims to save households an estimated average of £310 annually on energy bills. Over the entire duration of the scheme (from Summer 2023 to March 2026), this could translate into substantial savings for participating households.

Environmental Impact: The Great British Insulation Scheme is expected to significantly reduce carbon emissions. It is projected to cut CO2 emissions by millions of tons over its operational period, contributing to the country’s climate goals.

Accessible Application Process: The application process for grants is designed to be user-friendly, making it easier for homeowners to participate. Applicants will only need to meet basic eligibility criteria to access the subsidies.

Long-Term Benefits: The scheme not only provides immediate cost savings but also offers long-term benefits by enhancing home insulation, making properties more energy-efficient, and increasing comfort levels for residents.

What Home Insulation Can You Get?

Under the Great British Insulation Scheme (GBIS), various types of insulation are available to eligible households. These include:

Cavity Wall Insulation: This involves filling the gaps between the external and internal walls of a home, which are typically found in houses built after the 1920s.

Solid Wall Insulation: Applicable for homes with solid walls (without a cavity), this can be installed either internally or externally to improve heat retention.

Loft Insulation: Installing insulation in the loft or attic space to reduce heat loss through the roof.

Flat or Pitched Roof Insulation: Similar to loft insulation but specific to the types of roofs mentioned.

Underfloor Insulation: Insulating beneath the floorboards to prevent heat loss through the floor.

Solid Floor Insulation: Similar to underfloor insulation, but specifically for homes with solid floors.

Park Home Insulation: Specialised insulation options for park homes.

Room-in-Roof Insulation: Insulation for rooms that are built into the roof space, like converted attics.

The savings from these insulation measures can vary depending on the type of insulation installed, the size of the property, and its current energy efficiency. On average, households benefiting from the GBIS are expected to see a reduction in their energy bills of around £300-400 per year. This figure not only represents direct savings on energy bills but also contributes to the UK’s Net Zero ambitions by reducing greenhouse gas emissions.

Who is eligible for this grant?


The eligibility for free insulation and potentially other energy-efficient improvements under the Great British Insulation Scheme (GBIS) and the Energy Company Obligation (ECO) scheme can be categorised into two main groups: the ‘low income’ group and the ‘general’ group.

  • The ‘Low Income’ Group:
    • This category is for homeowners (or some private renters).
    • The property must have an Energy Performance Certificate (EPC) rating of D or below (E or below if renting).
    • Eligibility extends to households where a resident qualifies for certain benefits. These include Pension Credit, Universal Credit, Child Benefit (subject to income limits), Income Support, and Housing Benefit, among others.
    • Residents of social housing or those identified by their local council as low income (total household income under £31,000 per year) and vulnerable to cold living conditions are also eligible.
    • Under this group, eligible households can have multiple energy-efficient improvements made to their home.
  • The ‘General’ Group:
    • Eligibility here is for homeowners and tenants (including those renting privately or from a housing association).
    • The home should be in Council Tax bands A to D in England, or A to E in Scotland and Wales.
    • The property should have an EPC rating of D or below.
    • Under the GBIS, eligible individuals in this category may receive free insulation. However, the offer is typically limited to one type of insulation (for example, either cavity wall insulation or loft insulation, but not both).
    • There may be a requirement for the household to cover a portion of the costs, which will be clarified before any work commences.
