Frequently Asked Questions About Our Boiler Grants

What is ECO4?

ECO4 is a government energy grant running from 1 April 2022 to 31 March 2026. This four-year energy efficiency scheme targets the UK’s least efficient properties, providing free home insulation and heating upgrades—especially for low income households and those considered vulnerable.

Where does the funding come from?

The ECO energy scheme is funded by medium and large energy suppliers in the UK. These companies are legally obligated to provide free heating upgrades and other energy saving measures to improve the efficiency of UK homes. Each supplier’s contribution is based on its share of the domestic energy market, and they work closely with accredited installers to deliver these improvements nationwide.

How do I become eligible for ECO4 funding?

The first step is to check your ECO4 eligibility. Use our simple tool to check if you qualify for a free boiler check or other energy-saving upgrades. If eligible, we’ll take care of the rest—getting your grant approved and your improvements underway.

Is the UK Government involved in this scheme?

The ECO4 scheme is the latest phase of the UK’s fuel poverty scheme, part of ongoing government energy support to improve energy efficiency across the country. Designed to provide help with energy bills, ECO4 specifically targets low-income families and vulnerable households most affected by rising energy costs.

What energy-saving measures are available?

This includes a range of energy-saving options such as cavity wall insulation, external wall insulation, solid wall insulation, loft insulation, and both flat roof and pitched roof insulation. There are also effective solutions available for underfloor insulation, helping to maximise warmth and reduce heat loss throughout your home.

How much can I save with a new boiler?

Installing a new A-rated energy efficient boiler can reduce heating costs by 20–30%, offering long-term boiler savings while protecting you from future energy price increases.
