Free New Boiler Replacement Grants are a UK government initiative designed to reduce carbon footprints, increase energy efficiency, and lower household energy bills. Through the government’s free boiler grant scheme, you can replace your old, inefficient, and costly boiler with a brand-new, energy-efficient boiler model — completely free of charge. Upgrade to an A-rated condensing boiler at no cost through a Heat1 installer approved under the ECO4 scheme. 

To reduce carbon emissions, cut heating costs, and help fuel-poor households stay warm.

The ECO4 grant is a government initiative aimed at reducing fuel poverty and lowering carbon emissions. Households with an EPC rating below D may qualify for the free boiler grant. Low-income households, individuals receiving benefits, and pensioners can apply without worrying about the cost. To qualify, you must meet both household and benefit-based criteria. Here’s the ECO4 free boiler grants eligibility:

1. Homeownership

• You must own your home.
• Your property must have an inefficient or broken boiler (usually 15+ years old).

2. Household low Income

• Annual income must be below £31,000 (combined).

3. You Receive One or More of the Following Benefits:

• Universal Credit
• Pension Credit (Guarantee or Savings)
• Income Support
• Job Seeker’s Allowance (JSA)
• Employment and Support Allowance (ESA)
• Child Tax Credit
• Working Tax Credit
• Housing Benefit
• Child Benefit (with income threshold met)

4. EPC Rating

• If your home isn’t energy efficient (low EPC rating), you’re more likely to get help from a government grant.

Getting started with the free boiler grants application process is simple. Here’s how:

No upfront costs

The grant fully covers the boiler and installation for eligible applicants.

• Lower energy bills – New Gas boilers are up to 90% efficient
• Home comfort – Consistent and reliable heating
• Reduced carbon footprint – More environmentally friendly
• Property value boost – Better EPC rating can improve resale value
• Zero installation cost – Fully funded through government-backed schemes

Particular attention is given to vulnerable groups such as pensioners and low income families. Free boiler grants for pensioners ensure that older citizens maintain a warm home, while free boiler grants for low income households help families reduce fuel bills. This scheme also helps low-income families upgrade to a free boiler. Save money, reduce your carbon footprint, and keep your home warm all year round. If a household has a total income of £31,000 or less, they may qualify for a free boiler grant and insulation.

If approved, the grant typically includes:

• New A-rated condensing boiler
• Professional installation
• Upgraded heating controls
• Optional insulation (loft or cavity wall, if required)

There’s no repayment required, and no impact on your benefits.
