Home Insulation Grants

An insulation grant can help make your home keep warmer, cut energy bills, and reduce greenhouse gas emission. By improving insulation, you prevent heat loss, keeping your home comfortable in winter and cooler in summer. These grants provide support for insulation costs helping you save money annually while also being more energy-efficient and eco-friendly.

ECO4 Scheme

ECO4 Scheme is the fourth phase of Energy Company Obligation (ECO), which aims to help those families who cannot afford upgrading their home heating and insulation. A key objective of the ECO4 scheme is to improve the Energy Performance Certificate (EPC) ratings of homes. Improving EPC ratings makes homes more energy-efficient, which lowers energy bills and helps protect the environment.
The ECO4 Scheme has made a significant impact in the UK. These installations help families stay warm, reduce energy waste, and cut down on carbon emissions. So far, it has led to the installation of:

Great British Insulation Scheme

The Great British Insulation Scheme (formerly ECO+) was initiated in late March 2023, and in its first year after the launch, over 11,600 insulation measures had been installed in 9,400 homes. GBIS focuses on improving the energy efficiency of homes that do not qualify for the ECO4 scheme. With a £1 billion budget, this initiative aims to help about 300,000 households across the UK to reduce fuel poverty and lower carbon emissions. Unlike ECO4’s ‘whole-house approach,’ GBIS typically provides just one type of insulation per home. It mainly covers loft and cavity wall insulation, which can save households up to £300 annually.
