The Great British Insulation Scheme, previously known as ECO+, is an initiative launched by the government to address energy inefficiency in homes across the nation. This scheme aims to support approximately 300,000 households from the summer of its launch until March 2026. 


The primary objective is to encourage homeowners to invest in home insulation, ultimately making their residences more energy-efficient and leading to significant cost savings on energy bills.

Benefits of the Scheme

Energy Efficiency and Cost Savings

One of the major advantages of the Great British Insulation Scheme is its potential to transform homes into energy-efficient spaces. By installing quality insulation, households can significantly reduce their energy consumption, resulting in substantial savings on utility bills. Experts estimate that participating in the scheme could save consumers an impressive £300 to £400 annually.

Assistance for Low-Income Households

The scheme goes the extra mile to help those in vulnerable financial situations. It offers a boost to low-income households, providing them with the necessary financial aid to carry out insulation installations. This ensures that even those with limited means can participate and experience the benefits of an energy-efficient home.

Expanding Support for Energy-Inefficient Homes

The Great British Insulation Scheme extends its support to homes that fall within the lower brackets of energy efficiency. Specifically, it targets properties with an Energy Performance Certificate (EPC) rating of D or below. By focusing on these energy-inefficient homes, the scheme aims to address the root causes of excessive energy consumption and transform them into more eco-friendly living spaces.

Council Tax Band Support

Not only does the scheme target homes with low EPC ratings, but it also assists households falling under the lower Council Tax bands. In England, this includes bands A to D, while in Scotland and Wales, it encompasses bands A to E. By providing support to these households, the scheme ensures that a broader spectrum of the population can benefit from energy efficiency measures.

Eligibility Criteria

Before homeowners can take advantage of the Great British Insulation Scheme, they need to meet certain eligibility criteria set by the government. These criteria serve as guidelines to ensure that the scheme reaches those who need it the most.

Income Requirements

To qualify for the financial support offered by the scheme, applicants must meet specific income requirements. These requirements aim to target low-income households, providing them with the necessary funds to undertake home insulation projects.

Energy Performance Certificate Rating

The scheme focuses on properties with Energy Performance Certificate ratings of D or below. These properties are considered less energy-efficient and are likely to benefit the most from insulation installations.

Council Tax Band Criteria

Another important criterion for eligibility is the Council Tax band in which the property falls. Homes within the lower Council Tax bands (A-D in England, and A-E in Scotland and Wales) are given priority to ensure that the benefits of the scheme are accessible to a wider range of households.

Types of Insulation Covered

The scheme covers various types of insulation, each playing a crucial role in enhancing energy efficiency.

Loft Insulation

One of the primary areas of focus is loft insulation. By properly insulating the loft, homeowners can prevent heat loss and maintain a comfortable indoor environment.

Cavity Wall Insulation

For properties with cavity walls, this type of insulation fills the gap between the walls, effectively reducing heat loss and energy wastage.

Solid Wall Insulation

Solid walls can have their thermal efficiency improved through external wall insulation. Homes with solid walls can benefit from this insulation type, which helps retain heat and contributes to a more eco-friendly living space.

Floor Insulation

Floor insulation is another aspect addressed by the scheme, ensuring that heat is not lost through the flooring, ultimately enhancing energy efficiency.

Draught Proofing

Addressing drafts and air leaks in the home can significantly improve energy efficiency. Draught proofing is a cost-effective measure that the scheme supports.


The Great British Insulation Scheme promises to revolutionise energy efficiency in homes across the nation. By offering financial aid and support to low-income households and targeting energy-inefficient properties, the scheme ensures that everyone can participate in the drive for a greener, more sustainable future. Investing in home insulation not only leads to significant cost savings but also helps in the fight against climate change.
