Introduction: Understanding ECO4 Boiler Grants in 2025
The cost of home heating is rising, and for many UK households, upgrading to a modern, energy-efficient boiler is out of reach without financial assistance. The ECO4 scheme—the latest phase of the government’s Energy Company Obligation—offers grants that could mean a brand-new, free boiler for eligible homes. This guide from applyfreeboiler.co.uk explains who qualifies, how the process works, and why acting now could save you thousands.
What Is the ECO4 Boiler Grant?
The ECO4 scheme is a government-backed initiative designed to improve the energy efficiency of UK homes, reduce carbon emissions, and help low-income households cut their energy bills. The scheme targets homes most in need—those with outdated, inefficient boilers and low Energy Performance Certificate (EPC) ratings.
Background & Relevance
- Launched as the fourth phase of the Energy Company Obligation (ECO) in 2022, ECO4 runs through March 2026.
- The focus is on fuel-poor households, prioritizing properties with EPC ratings of D or lower and boilers over eight years old[1][4].
- By subsidizing new A-rated boilers and insulation measures, ECO4 helps households save money and supports the UK’s net-zero carbon targets[1][4].
Who Qualifies for a Free Boiler Under ECO4?
Eligibility for ECO4 is determined by a combination of household income, benefit status, property type, and the condition of your current heating system.
Core Eligibility Criteria
- Property Type: Homeowners and private tenants (with landlord’s permission) are eligible. Social housing tenants may qualify if their EPC is D or lower[1][4][5].
- Boiler Age: Your existing boiler should be at least 8 years old for ECO4 grants[1][4].
- Household Income: Generally, annual income should be £31,000 or less under ECO4 Flex, with stricter limits in some cases[1][4].
- Benefit Status: Receiving benefits such as Universal Credit, Pension Credit, Child Benefit, or Jobseeker’s Allowance greatly increases your chances[1][4].
- Energy Efficiency: Your home must have an EPC rating of D or lower[1][4].
