ECO4, Energy Company Obligation 4
ECO4 is the UK government's most ambitious energy efficiency scheme, providing free insulation, boiler replacements, heat pumps, and more to qualifying households. Find out if you're entitled to thousands of pounds of improvements at no cost.
What is ECO Funding?
The Energy Company Obligation or 'ECO' is a domestic energy efficiency funding programme directed by government and paid through the green levy by large energy companies. As a trusted partner with years of experience, we work with local authorities and councils to create energy efficient homes, delivered through the ECO scheme, enabling us to achieve a reduction in fuel poverty and improve the overall energy efficiency of homes across the UK.
Together with our contractors, we deliver a variety of home insulation measures such as cavity wall and loft insulation, to thermostat valves, solar panels and much more. We offer extra warmth for your home at no cost to you and the best part is, you don't have to be an Experthousing customer to benefit.
Helping the UK's most vulnerable households keep warm, save money and reduce carbon emissions by delivering the right solutions for them.

What Does ECO4 Cover?
ECO4 covers a far broader range of improvements than previous schemes. Here are the main measures available to qualifying households.
Loft Insulation
Prevents up to 25% of heat loss through the roof. Saves an average of £445/year and cuts CO₂ by up to 1,000kg annually.
Cavity Wall Insulation
Fills the gap in cavity walls to prevent up to one third of heat loss. Installed by accredited partner installers with a 25-year guarantee.
Solid Wall Insulation
Internal or external insulation for pre-1920 solid-walled homes, dramatically improving energy efficiency ratings.
Boiler Replacement
Replace an old, inefficient boiler with a modern A-rated condensing boiler. Significant bill savings and reduced carbon output.
Air Source Heat Pumps
A low-carbon alternative to gas boilers, generating heat from the outside air even in cold weather. Eligible for the Boiler Upgrade Scheme top-up.
Solar PV Panels
Generate free electricity from the sun, reduce energy bills dramatically, and export surplus energy back to the grid.
First-Time Central Heating
For homes with no existing central heating, ECO4 can fund the installation of a complete heating system.
Underfloor Insulation
Insulating beneath timber ground floors to eliminate cold draughts and reduce heat loss through the floor.
ECO4 Schema Benefit

ECO is a scheme requiring energy suppliers to improve energy-efficiency in UK homes while tackling fuel poverty. Running since 2013, this latest phase of the scheme has £4 billion of funding allocated to it and it is expected to run until 31 December 2026.

Average Savings
It will reduce household bills by around £290 on average, but for the least efficient homes this could be up to £1,600.
Scheme Duration
ECO4 is expected to run until 31 December 2026. Energy suppliers are to deliver lifetime savings by installing energy efficiency measures.
