Eligibility for ECO4 Grants in the UK: A Comprehensive Guide

The Energy Company Obligation (ECO) scheme has been instrumental in helping households across the UK improve their energy efficiency, reduce energy bills, and decrease carbon emissions. The latest iteration, ECO4, continues this mission with a focus on supporting low-income households and those in fuel poverty. Understanding who qualifies for these grants is crucial for those seeking to benefit from the scheme. Here, we break down the eligibility criteria for ECO4 grants.

What is ECO4?

ECO4 is the fourth phase of the ECO scheme, which mandates large energy suppliers to fund energy efficiency improvements in homes. This phase, running from April 2022 to March 2026, aims to deliver greater energy efficiency and carbon savings by targeting the most vulnerable households.

Who is Eligible?

Eligibility for ECO4 is determined by a range of factors, including income level, benefits received, and the current state of the property. Here are the primary criteria:

  1. Income and Benefits: ECO4 is aimed primarily at low-income households. To qualify, at least one member of the household must receive one of the following benefits:
    • Income-based Jobseeker’s Allowance (JSA)
    • Income-related Employment and Support Allowance (ESA)
    • Income Support (IS)
    • Pension Credit (guarantee credit)
    • Working Tax Credit (WTC)
    • Child Tax Credit (CTC)
    • Universal Credit (UC)
    • Housing Benefit
    • Pension Credit (savings credit)
    Additionally, those earning below a certain threshold (as determined by the household composition and income) may also be eligible.
  2. Property Eligibility: The scheme targets homes that are particularly inefficient. Properties are assessed based on their Energy Performance Certificate (EPC) rating. Generally, properties with an EPC rating of D, E, F, or G are eligible for improvements under ECO4. These ratings indicate that the property is not energy efficient and would benefit from upgrades such as insulation, heating improvements, or the installation of renewable energy sources.
  3. Local Authority Flexibility (LA Flex): Some households that do not meet the strict criteria above may still qualify under the Local Authority Flexibility mechanism. This allows local councils to recommend households that may not be on the benefits list but are still vulnerable to fuel poverty. Local authorities have their own criteria and assessment processes, so it is worth checking with your local council to see if you might qualify under this route.

Types of Improvements Covered

ECO4 covers a wide range of energy efficiency improvements, including:

  • Loft, cavity wall, and solid wall insulation
  • Boiler upgrades or replacements
  • Installation of first-time central heating systems
  • Renewable energy installations, such as solar panels
  • Draught proofing and other minor energy-saving measures

How to Apply

Applying for an ECO4 grant typically involves the following steps:

  1. Assessment: Contact an accredited ECO provider or your local authority to arrange a home energy assessment. This will determine the current energy efficiency of your property and identify suitable improvements.
  2. Eligibility Check: During the assessment, the provider will check your eligibility based on your income, benefits received, and the state of your property.
  3. Approval and Installation: If you meet the criteria, the provider will work with you to plan and install the necessary improvements. The cost of these improvements is covered by the grant, ensuring you receive the benefits without an upfront financial burden.


ECO4 grants offer a valuable opportunity for eligible UK households to improve their energy efficiency, lower energy bills, and reduce carbon footprints. By understanding the eligibility criteria and the application process, you can take the first steps toward a more energy-efficient home.
