Frequently Asked Questions About Our Boiler Grants

What is ECO4?

ECO4 is a four-year government energy scheme running from 1 April 2022 to 31 March 2026, focused on delivering energy efficiency improvements and free heating upgrades to the UK’s least efficient homes—particularly those occupied by low-income residents and offering vital support for vulnerable families.

Where does the funding come from?

The UK home energy scheme is funded by medium and large obligated suppliers, who are required to provide funded energy upgrades to improve household efficiency. Each supplier’s responsibility is based on their share of the domestic energy market. To meet these targets, they partner with certified installers to deliver nationwide energy-saving improvements across homes throughout the UK.

How can I qualify for ECO4 funding?

The first step is to check your ECO4 eligibility. Use our simple grant qualification tool to see if your home qualifies for an energy-saving grant application—then get started with ECO4 while we handle the rest of the process for you.

Does it have anything to do with the UK Government?

The ECO4 energy-saving scheme is the latest phase of the UK energy efficiency initiative, designed to reduce fuel poverty by providing vital help for low-income households. This government-backed program focuses on improving home energy standards across the country.

What energy saving measures can I get?

The ECO4 insulation options include a wide range of upgrades such as internal and external wall insulation, cavity wall insulation, as well as flat roof and pitched roof insulation. You can also benefit from underfloor insulation solutions, all designed to insulate your home more effectively and reduce heat loss year-round.
