As energy prices surge and climate concerns intensify, the UK government’s ECO4 Scheme has emerged as a vital solution for helping households cut energy costs while reducing carbon emissions. Designed to support low-income and energy-inefficient properties, the ECO4 Scheme delivers fully or partially funded home improvements — from insulation and heat pumps to solar panels and smart heating controls. But how does the scheme work, who qualifies, and what upgrades are available? Below is a complete, research-backed guide to the ECO4 Scheme in 2024.
What Is the ECO4 Scheme?
The ECO4 Scheme is the fourth phase of the Energy Company Obligation (ECO) — a government-backed initiative running from July 2022 to March 2026. Under this mandate, large UK energy suppliers are legally required to fund energy-efficiency improvements in homes that are difficult to heat and fall into lower income brackets. The ultimate goals are to:
- Lower household energy bills
- Eliminate fuel poverty
- Cut carbon emissions to help meet the UK’s net-zero targets by 2050
While previous ECO phases focused heavily on single upgrades such as boiler replacements, ECO4 aims for whole-house retrofits, combining multiple measures to elevate homes to EPC (Energy Performance Certificate) band C or above wherever practical.
How Does the ECO4 Scheme Work?
Energy companies like British Gas, EDF, E.ON, and Scottish Power provide financial support to approved installers, who then carry out eco-friendly upgrades on eligible homes. These improvements can be installed free of charge, or at a significantly reduced cost, depending on the scope of work and the funding available.
Typical ECO4 upgrades include:
- Solar PV panels
- Loft, cavity wall, and underfloor insulation
- Air source heat pumps
- First-time central heating systems
- Smart heating controls and thermostatic radiator valves
Why the ECO4 Scheme Matters in 2024
The ECO4 Scheme comes at a critical time, offering benefits that extend beyond just energy savings.
💸 Combat Rising Energy Bills
UK energy costs remain volatile, and heating is the biggest contributor to household consumption. ECO4 upgrades could save qualifying homes £300–£1,600 per year, depending on the mix of measures installed.
🌍 Environmental Responsibility
Homes currently account for 15% of the UK’s total carbon emissions. By improving energy efficiency and transitioning to cleaner technologies like heat pumps and solar energy, the ECO4 Scheme plays a crucial role in decarbonising the housing sector.
🏡 Healthier Living Conditions
Cold, inefficient homes are linked to respiratory issues and damp. Improving insulation and heating helps create warmer, drier homes that support health and wellbeing — especially important for families with children or elderly residents.
Who Is Eligible for the ECO4 Scheme?
Eligibility is based on income, benefit status, and the energy performance of the property.
✅ Eligible Households Must:
- Own or privately rent a property with an EPC rating of D, E, F, or G
- Receive at least one qualifying UK government benefit, such as:
- Universal Credit
- Child Benefit (income-assessed)
- Pension Credit
- Income-based Jobseeker’s Allowance (JSA)
- Income-related Employment & Support Allowance (ESA)
- Housing Benefit
- Working or Child Tax Credit
- Income Support
🚪 What About Those Not on Benefits?
Many local authorities also participate in “LA Flex” (Local Authority Flexible Eligibility), which allows households not receiving benefits to qualify if they are:
- On a low income AND
- Living in a hard-to-heat home (often due to poor insulation)
This makes it worth checking with local councils or approved installers, even if you do not claim benefits.
What Types of Improvements Can the ECO4 Scheme Fund?
Upgrade Type | Purpose |
Loft & Roof Insulation | Reduce heat loss through top of house |
Cavity / Solid Wall Insulation | Improve building thermal efficiency |
Underfloor Insulation | Slash draughts and cold floor surfaces |
Air Source Heat Pumps | Replace gas boilers with low-carbon heating |
Solar Panels (PV) | Generate electricity from sunlight |
First-Time Central Heating | Install complete heating system |
Heating Controls | Optimise energy use in existing systems |
How to Apply for the ECO4 Scheme
- Confirm your Benefit Status or LA Flex suitability
Check eligibility based on benefits or contact your local authority for LA Flex approval. - Check your EPC Rating
Use the official government EPC register or arrange an assessment. If your rating is D–G, you’ll typically qualify. - Contact a TrustMark-registered ECO4 Installer
Only authorised installers can process ECO applications. They’ll handle all paperwork and conduct a home energy survey. - Home Assessment & Installation Plan
Approved installers determine which combination of measures best lifts your property’s energy efficiency. - Install & Save!
Scheduled works usually take place over the course of a few days to a few weeks depending on scale. Enjoy long-term energy savings and increased comfort.
Frequently Asked Questions About the ECO4 Scheme
Is the ECO4 Scheme completely free?
Often yes — especially for households on certain income-related benefits. In some cases, a small contribution might be required, depending on the type of improvements.
Can private tenants apply?
Yes, private renters are eligible with landlord permission. Social housing tenants should check alternative schemes, as ECO4 does not typically cover social housing stock.
Can I get a new boiler through ECO4?
Boilers are not a primary focus under ECO4 unless included within a more comprehensive upgrade plan. ECO4 prefers low-carbon systems like heat pumps.
Final Thoughts
The ECO4 Scheme presents an exceptional opportunity for UK households to upgrade energy-inefficient homes, fight fuel poverty, and contribute to climate action — all with financial support from energy suppliers rather than homeowners. If you live in a cold or expensive-to-run home, checking your eligibility could be the start of a transformative journey toward lower bills, increased property value, and a greener lifestyle.
