ECO4 Grants 2025: Complete Guide to Eligibility and How to Apply

The ECO4 Grants is a lifeline for UK households struggling with energy bills. With rising fuel costs and growing climate concerns, this government-backed initiative offers free or heavily subsidized energy efficiency upgrades to eligible homes. If you’re wondering how to tap into these benefits, this guide breaks down everything you need to know about ECO4 Scheme in 2025—from eligibility rules to the application process.

What is the ECO4 Scheme?

The Energy Company Obligation (ECO4) is a government program requiring large energy suppliers to fund home improvements that reduce energy consumption. Running until March 2026, it targets low-income households and vulnerable residents, offering upgrades like:

• Insulation (loft, cavity wall, underfloor)

• Boiler replacements (for inefficient systems)

• Solar panels

• Air source heat pumps

The goal? Cut energy bills, reduce carbon emissions, and lift families out of fuel poverty.

Who is Eligible for ECO4 Grants in 2025?

Eligibility hinges on income, benefits, and property type. Here’s the latest criteria:

1. Income Thresholds

• Households with a total annual income under £31,000 (varies by region).

• Benefit recipients automatically qualify if they receive:

  • Universal Credit

  • Pension Credit

  • Child Tax Credits

  • Income-related ESA/JSA

2. Property Requirements

• EPC Rating: Homes must have an EPC rating of D, E, F, or G (lowest efficiency).
