Looking to improve your home’s energy efficiency? You can now apply for ECO4 funding, a UK government scheme helping households save on heating upgrades and insulation. Through trusted partners like Eco Green Grant, eligible homes can benefit from fully or partially funded improvements. This scheme not only lowers bills but also supports the shift to a greener future.
What Is the ECO4 Scheme?
ECO4: Government Support for Greener Homes
🏡 What Is ECO4?
ECO4 is a UK government scheme to improve energy efficiency in low-income and vulnerable households.
🔧 Types of Help
Includes heating upgrades, boiler replacements, wall and loft insulation, and smart controls.
👥 Who Qualifies?
Homeowners and tenants receiving benefits or on low incomes may qualify under set criteria.
🌿 Purpose
The goal is to reduce fuel poverty and cut carbon emissions by improving home energy performance.
ECO4 runs from 2022 to 2026 and replaces the earlier ECO3 scheme with stricter energy performance targets.
The ECO4 scheme is part of the UK Government’s long-term energy-saving strategy. It offers financial support for energy efficiency upgrades in qualifying homes. Funded by energy suppliers under the energy company obligation, it helps low-income and vulnerable households. ECO4 will run until March 2026, so there’s still time to benefit.
How the ECO4 Scheme Works
The ECO4 scheme is funded by obligated energy suppliers who must help eligible households improve energy efficiency. The goal is to reduce carbon emissions and tackle fuel poverty. Funding covers insulation, boiler upgrades, and heat pumps. The upgrades are installed by certified installers, with minimal costs to the homeowner or tenant.
What Is Covered Under ECO4?
The scheme includes a wide range of energy efficiency measures. These include cavity wall insulation, loft insulation, internal wall insulation, and first time central heating. ECO4 also supports boiler upgrade and renewable heating systems like heat pumps. The Nottingham ECO4 scheme is designed to make your home more energy efficient while cutting heating costs.
Why ECO4 Replaced ECO3
ECO4 replaced ECO3 in 2022 with updated eligibility rules and extended support. The new version focuses more on households with poor energy efficiency ratings. It also brings more flexibility (ECO4 Flex) for local authorities to nominate homes in need. With an emphasis on deep retrofit, ECO4 offers more comprehensive support.

Whether you own the property or rent it, ECO4 offers funding pathways to create more energy-efficient homes across the UK.
If you’re a landlord or a tenant, there are specific things to keep in mind. ECO4 funding can be accessed by private renters too—with the right permissions.
What Landlords Need to Know
Landlords can use ECO4 funding to upgrade the energy efficiency of their properties. It helps comply with minimum EPC requirements and reduces heating complaints. Consent from tenants is often required. The upgrades can increase property value and tenant satisfaction.
Tenants Can Also Benefit
Tenants may qualify for the ECO4 scheme if they meet the eligibility criteria. However, installations like insulation or boilers require landlord permission. The process is managed by the installer, who will communicate with all parties involved. It’s a win-win for both tenant and landlord.
Legal and Compliance Matters
Landlords must ensure upgrades meet local building regulations and ECO4 standards. Using a certified installer helps avoid future disputes. All works are registered with the proper authorities, and documentation is provided. It protects everyone involved.
Local Authorities and ECO4 Flex
Understanding How LA Flex Works Within the ECO4 Scheme
🏛️ What Is LA Flex?
LA Flex allows local councils to define eligibility beyond standard benefit rules for ECO4 funding.
📋 Flexible Criteria
Authorities can prioritize fuel-poor, vulnerable, or low-income households not receiving benefits.
🌍 Local Impact
Tailored funding helps address regional challenges like rural energy access or urban fuel poverty.
🤝 Collaboration
Installers, councils, and residents work together to verify needs and deliver energy-saving measures.
LA Flex empowers councils to support more households—bridging the gap between policy and practical help.
Local councils play a crucial role in expanding ECO4 eligibility through ECO Flex, especially for vulnerable households not on benefits.
What Is ECO4 Flex?
ECO4 Flex allows local authorities to refer households that don’t meet traditional benefit-based eligibility. They consider fuel poverty, low income, or health-related issues. It gives councils more say in who receives eco4 funding in their area.
Who Is Eligible Under ECO4 Flex?
People with chronic illnesses, disabilities, or high heating needs may qualify for ECO4 funding under Flex. Income thresholds vary by council. Flex helps reach people who’d otherwise be left out of traditional schemes. Always ask if Flex is available in your area.
How to Apply via Local Authority
Your local council must assess and approve your Flex eligibility. You’ll need to fill out a referral form and provide documents. After approval, you’ll proceed as normal through the eco4 application process. Your installer or council can assist with this step.
ECO4 and Energy Suppliers
“I was really struggling with high energy bills in my old home. Thanks to the Eco Green Scheme, I got a new boiler and wall insulation installed completely free. The process was smooth, and the team was incredibly helpful. My home is warmer, and my bills are noticeably lower!”
— Sarah M., Nottingham
Energy suppliers are the ones funding the scheme and working with installers to deliver energy-saving upgrades across the UK.
Role of the Energy Supplier
The energy company obligation requires major suppliers to fund improvements for eligible households. They work with registered installers to carry out insulation, heating, and boiler upgrades. Without them, the ECO4 scheme wouldn’t be possible.
How to Find an Obligated Supplier
Only certain obligated suppliers are part of the Energy Company Obligation (ECO4) program. You can ask your current energy supplier directly or check online listings. If your supplier isn’t obligated, you can still apply through others who are. The grant follows the installer, not the supplier.
What Energy Companies Must Provide
Suppliers must offer clear guidance, ensure certified installations, and meet deadlines for project completion. They are accountable to Ofgem. Your installer handles the communication, but it’s useful to understand how your energy company helps fund your upgrade.
