ECO4 is the latest phase of the UK Government’s Energy Company Obligation, running from 2022 until 31st March 2026. It helps low‑income and vulnerable households improve their home’s energy efficiency through free or subsidised measures such as insulation, heating, and solar upgrades. The aim is to reduce energy bills, cut carbon emissions, and improve the EPC rating of inefficient homes.

The Great British Insulation Scheme is a government-backed programme that provides free or subsidised insulation for homes across the UK. It’s designed to help households cut energy bills, improve warmth, and reduce carbon emissions by installing measures like loft, cavity wall, and solid wall insulation.

Households may qualify for ECO4 if they meet the following:

• The property has a low EPC rating (usually E, F or G). 

And one of the below

• Someone in the home receives an eligible benefit, such as Universal Credit, Pension Credit, Income Support, Tax Credits.

• A resident is considered vulnerable to cold or fuel poverty (LA Flex Routes)

1.     Total Household Income below £31,000

2.     Health Conditions (Cardiovascular, Respiratory, Immunosuppressed, or Limited Mobility 

The Great British Insulation Scheme is open to households with homes in EPC bands D–G and those in lower Council Tax bands. You may also qualify if someone in the home receives certain benefits or if your local authority identifies you as vulnerable to fuel poverty. The scheme mainly supports homes that would benefit most from insulation upgrades.

ECO4 helps households reduce energy bills, improve comfort, and upgrade inefficient homes through funded energy‑saving measures. It can increase your property’s EPC rating, lower carbon emissions, and provide long‑term savings by installing modern, efficient heating and insulation.

Once your eligibility is confirmed, we’ll arrange a Retrofit Assessment for your property. An in‑house Assessor will complete a whole‑house survey, taking photos and measurements to identify which ECO-funded improvements are suitable. Using this information, our Retrofit Coordinator will create an Improvement Plan outlining the recommended measures and installation order. Our operations team will then schedule the installation and advise on timings. After the work is completed, we’ll submit all compliance paperwork to our funders so you can simply enjoy the improvements and the energy savings.

ECO4 funding covers insulation (loft, cavity wall, solid wall, and underfloor), heating upgrades such as heat pumps, and heating controls. The focus is on improving energy efficiency.

Yes, most ECO4-approved installers offer free home energy surveys. These assessments check your property’s insulation, heating system, and energy efficiency to see what improvements qualify under ECO4. The survey helps determine eligibility and ensures the correct measures are installed at no cost to you.

We can help make the ECO4 funding process simple and stress-free. Just contact us, and we’ll guide you through every step. We’ll check your eligibility, arrange a free home survey, and handle the application for you. Once approved, your insulation upgrades can be installed. Let us take care of the paperwork so you can enjoy a warmer, more energy-efficient home without the hassle.

The process starts with an eligibility check, followed by a free home energy survey. An assessor reviews your insulation, heating, and EPC rating. If your home qualifies, recommended improvements are approved, and installation is arranged by an accredited ECO4 installer.

Yes, ECO4 is delivered by a nationwide network of approved installers. Availability depends on your area, but most regions in England, Scotland, and Wales are covered. A local provider can assess your home and manage the application and installation process.

Yes, ECO4 is currently active and runs until March 2026. It is the government’s main energy efficiency grant scheme aimed at improving low-income and energy-inefficient homes. Funding is available while budgets last, so early application is recommended.

Yes, ECO4 is available to both homeowners and private or social housing tenants. Tenants must have landlord permission before work begins. Eligibility depends on income, benefits, property type, and energy efficiency rather than home ownership status.

Yes, receiving benefits such as Universal Credit, Pension Credit, or Child Tax Credit may make you eligible for ECO4. These benefits help demonstrate low household income, which is a key requirement for qualifying for energy efficiency improvements under the scheme.

Qualifying benefits include Universal Credit, Pension Credit (Guarantee or Savings), Income Support, Child Tax Credit, Working Tax Credit, Housing Benefit, and income-based Jobseeker’s Allowance or ESA. Eligibility also depends on household income and property energy efficiency.

ECO4 applies to houses and bungalows with poor energy efficiency ratings. Homes with low EPC ratings (typically D–G) are prioritised. Both owner-occupied and rented properties may qualify, depending on income and heating type.

The Great British Insulation Scheme (GBIS) typically covers loft insulation, cavity wall insulation, and sometimes solid wall insulation. It focuses on simpler, single-measure upgrades and is available to more households than ECO4, including some middle-income homes.

Yes, ECO4 is designed as a whole-house approach. If your home qualifies, you may receive multiple improvements such as insulation and heating upgrades together. The goal is to significantly improve energy efficiency rather than install just one measure.

ECO4 focuses on low-income households and deeper energy upgrades, often including multiple measures. GBIS is broader and mainly funds single insulation improvements. ECO4 offers more comprehensive support, while GBIS is simpler and quicker for basic upgrades.

We make applying for the ECO4 grant straightforward. When you get in touch with us, we’ll check your eligibility, arrange a free home survey, and submit the application on your behalf. If your application is approved, the insulation or energy-saving upgrades are installed with the cost covered by the scheme. We take care of all the steps so you can enjoy a warmer, more efficient home without any stress.

The full process usually takes a few weeks from eligibility check to installation. Times can vary depending on survey availability, installer schedules, and property type. Once approved, installation is usually completed within a few weeks.

Yes, ECO4 can vary slightly by local council, especially under ECO4 Flex. Councils can set their own eligibility rules to help households not on benefits. Availability and criteria may differ by area.

ECO4 Flex allows local councils to approve households that do not receive benefits but still struggle with energy costs. Councils set their own criteria, such as low income or health conditions, making the scheme more accessible to vulnerable households.
