In today's economic climate, reducing household energy bills is a priority for many families. If you’re struggling with high heating costs or dealing with an old, inefficient boiler, there’s good news: you may be eligible for a Free Boiler Grant under the UK government’s Energy Company Obligation (ECO) scheme.

This guide explains everything you need to know about boiler grants — who qualifies, how to apply, and the long-term benefits.

What is the Free Boiler Grant Scheme?

The Free Boiler Grant is part of the UK government’s ECO initiative, designed to help low-income households improve energy efficiency. Under this scheme, qualifying homeowners and tenants can have their old boilers replaced with new, energy-efficient models — completely free or heavily subsidised.

The grant is funded by major energy companies, who are legally obligated to help households reduce their carbon emissions and energy bills.

Who is Eligible?

To qualify for a Free Boiler Grant, you typically need to meet the following criteria:

• You must be a homeowner or private tenant

• Your existing boiler must be at least 8 years old

• You or someone in your household must receive qualifying benefits, such as:

  • Pension Credit (Guarantee Credit element)

  • Universal Credit

  • Income Support

  • Child Tax Credit

  • Working Tax Credit

  • Housing Benefit

  • ESA or JSA (income-based)

Note: Some grants may also be available to those not receiving benefits, depending on local authority schemes and the current version of the ECO program.

Why Should You Replace Your Old Boiler?

Upgrading to a new A-rated boiler can significantly cut your heating bills — in some cases by up to £300 a year. Older boilers are often only 60–70% efficient, meaning much of the energy (and money) is wasted.

A modern condensing boiler, by contrast, can reach 90%+ efficiency, delivering more heat for less cost. Plus, new boilers are more reliable and environmentally friendly.

How to Apply for a Free Boiler Grant

Applying is easier than you might think. Here’s how:

1. Check Your Eligibility
   Use an online eligibility checker on trusted boiler grant websites or contact an approved ECO installer.

2. Schedule a Home Assessment
   If you qualify, an installer will visit your home to inspect your existing boiler and heating setup.

3. Boiler Installation
   If approved, the installer will replace your old boiler — often within just a few days. The cost is fully or partially covered by the grant, depending on your circumstances.

Frequently Asked Questions

Q: Can I get a grant if I’m a tenant?

Yes — if you're a private tenant and meet the income and benefit criteria. However, your landlord must give consent for the work.

Q: Do I have to repay the grant?

No. The Free Boiler Grant is not a loan, and you do not have to pay it back.

Q: Is the grant available in my area?

The scheme is available throughout the UK, although some local councils offer additional support. It's best to check with approved grant providers in your region.

Final Thoughts

The Free Boiler Grant scheme is a fantastic opportunity to reduce your energy bills, upgrade your heating system, and make your home more energy-efficient — without upfront costs.

If you think you might be eligible, don’t wait. These schemes are often time-sensitive and subject to funding limits.
