Free Insulation Grant
Lower your heating bills and enjoy a warmer home with the help of the ECO4 insulation scheme. Eligible households can access a government-funded insulation grant, covering options like free loft insulation and wall insulation to improve comfort and energy efficiency year-round.
Keep Your Home Warm and Energy Efficient
Cavity wall insulation works by filling the space between your home’s internal and external walls, significantly helping to reduce heat loss. Common materials include urea formaldehyde foam, cellulose, mineral wool, and insulation beads—with most of our trusted cavity wall installers recommending polystyrene beads for their superior performance and long-term benefits.
Installing cavity wall insulation improves thermal comfort year-round—keeping your home warm in winter, cool in summer, and even helping to reduce noise. Best of all, it’s a proven way to enhance energy efficient walls and cut down on your heating costs.

Frequently Asked Questions About Our Boiler Grants
ECO4 is a four-year home energy efficiency scheme running from 1 April 2022 to 31 March 2026. Backed by ECO4 government funding, it focuses on delivering insulation support and heating upgrades to the UK’s least efficient homes—especially those occupied by vulnerable residents and households in need of energy help for low income families.
The ECO scheme is a government-backed heating scheme funded by medium and large UK energy providers. These companies are obligated to contribute energy efficiency funding based on their share of the domestic energy market. To meet their targets, they work closely with approved installers to install energy-saving upgrades in homes across the country, helping to reduce fuel bills and improve household comfort.
The first step is to confirm your ECO4 qualification. Use our free boiler grant checker to check boiler grant eligibility for your home, and our team will take care of the rest—guiding you through the entire energy upgrade support process.
The ECO4 scheme is the latest phase of the government energy efficiency scheme, part of the UK’s commitment to improving energy efficiency UK-wide.

This includes a range of insulation options such as internal wall insulation, external wall insulation, cavity wall insulation, solid wall insulation, flat roof insulation, and pitched roof insulation.
