Boiler Grant – Free Boiler Replacements Under ECO4 Scheme

The Boiler Grant is a UK government-backed initiative under the Energy Company Obligation (ECO4) scheme. It provides free or heavily subsidised boiler replacements to eligible homeowners and private tenants. The goal is to help reduce energy bills, improve home heating efficiency, and cut down carbon emissions.
If your existing boiler is old, broken, or inefficient, you may qualify for a brand-new A-rated boiler at little to no cost – including installation by a certified professional.

Who Can Apply?

You could qualify for a free boiler grant if:

• Your existing boiler is non-condensing, broken, or inefficient

• You are a homeowner or private tenant (with landlord permission)

• Someone in your household receives one or more qualifying benefits, such as:

  • Universal Credit

  • Child Tax Credit or Working Tax Credit

  • Income Support

  • Income-Based JSA or ESA

  • Housing Benefit

  • Pension Credit (Guarantee or Savings)

  • Child Benefit (subject to income threshold)
    You may also qualify under LA Flex – a flexible local authority route for low-income households who may not receive benefits but are vulnerable or have high energy costs.

What Does the Boiler Grant Cover?

If approved, the grant typically covers:

• A-rated energy-efficient condensing boiler

• Full installation by an approved heating engineer

• Smart thermostat and heating controls (if eligible)

• Pipework adjustments (if needed)

• Old boiler removal and disposal
  This is a non-repayable grant – there’s no loan, credit check, or hidden fees.
  

Why Replace Your Old Boiler?

Upgrading to a modern, A-rated boiler offers multiple benefits:

• Lower heating bills: Save up to £300+ per year compared to old G-rated boilers

• More reliable heating: No more breakdowns or cold winter nights

• Environmentally friendly: A-rated boilers reduce carbon emissions and improve EPC ratings

• Increased property value: More efficient homes appeal to buyers and renters

Boiler Types Supported by ECO4

ECO4 no longer supports oil boilers or non-renewable systems for new installations. However, eligible upgrades include:

• Gas boilers (in homes already connected to the gas grid)

• Electric boilers or hybrid systems (in some cases)

• Air source heat pumps as an alternative (if the boiler is not suitable)

• All installations must meet minimum energy efficiency standards, and in some cases, multiple upgrades (insulation + boiler) may be installed to meet ECO4 targets.
