Free Heat Pump Schemes UK: What's Available in 2026?

Yes, it is possible to get a heat pump installed completely free of charge in the UK. But — and this is important — free installations are only available to specific groups, primarily low-income and vulnerable households. If you earn a decent income and do not receive means-tested benefits, you will not qualify for a free heat pump. You can, however, still get £7,500 off through the Boiler Upgrade Scheme.

This guide cuts through the noise and explains exactly which free heat pump schemes exist, who genuinely qualifies, and how to access them. We will be straightforward about what is realistic and help you avoid scams along the way.

The Honest Truth About Free Heat Pumps

Before we list the schemes, let us set expectations clearly:

  • Free heat pump schemes exist — they are genuine government-backed programmes
  • They are targeted — you must be on a low income, receive certain benefits, or be in a vulnerable group
  • You do not get to choose — you typically cannot pick your installer, brand, or exact system specification
  • There may be a wait — demand is high and funding is limited
  • Not everyone who applies will get one — eligibility does not guarantee installation

With that said, thousands of UK households receive free heat pumps every year through these programmes. If you qualify, it is absolutely worth applying.

Route 1: ECO4 Scheme

The Energy Company Obligation (ECO4) is the largest source of free heat pump installations in the UK. It requires energy suppliers to fund energy efficiency improvements in qualifying homes.

Who Qualifies for Free Installation Through ECO4

  • Homeowners or private tenants (with landlord permission) who receive means-tested benefits
  • The property must have an EPC rating of D, E, F, or G
  • Available in England, Scotland, and Wales

Qualifying Benefits

  • Universal Credit (below the income threshold)
  • Pension Credit (Guarantee Credit)
  • Income-related ESA
  • Income-based JSA
  • Income Support
  • Child Tax Credits (below the income threshold)
  • Working Tax Credits (below the income threshold)
  • Housing Benefit

ECO4 Flex

Even if you do not receive qualifying benefits, your local council can refer you under ECO4 Flex if you are considered fuel-poor or vulnerable. Contact your council's housing team to ask about this route.

How to Access ECO4

  • Contact your energy supplier directly
  • Contact your local council about ECO4 Flex
  • Search for ECO4-approved installers in your area

Route 2: Nest Scheme (Wales Only)

The Welsh Government's Nest scheme provides free home energy improvements, including heat pump installations, to eligible households in Wales.

Who Qualifies

  • Welsh homeowners receiving means-tested benefits
  • Properties with an EPC rating of E, F, or G
  • Vulnerable households (elderly, disabled, young children, pregnant)

How to Access Nest

Call the Nest helpline on 0808 808 2244. The service is free and available in English and Welsh.

Route 3: Warmer Homes Scotland (Scotland Only)

Delivered through Home Energy Scotland, the Warmer Homes Scotland programme provides free energy efficiency improvements, including heat pumps, to eligible Scottish households.

Who Qualifies

  • Scottish homeowners receiving qualifying benefits
  • Homeowners on a low income who are vulnerable to the effects of cold

How to Access

Call Home Energy Scotland on 0808 808 2282 for a free assessment of your eligibility.

Route 4: Local Authority Schemes

Many local councils run their own energy efficiency programmes that can include free heat pump installations. These are funded through various government grants and local budgets.

Examples of Local Authority Funding

  • Home Upgrade Grant (HUG): Targets off-gas-grid homes with low EPC ratings in England. Can fund heat pumps and insulation for low-income households.
  • Local authority delivery partners: Some councils partner with energy companies to deliver free or low-cost installations in specific areas.
  • Area-based schemes: Targeted programmes for specific postcodes or housing types.

How to Find Local Schemes

  • Contact your local council's housing or environmental team
  • Check the Simple Energy Advice website (England)
  • Ask the Energy Saving Trust
  • Search for "[your council name] free heat pump" or "[your council name] energy efficiency grants"

Route 5: Social Housing Programmes

If you live in social housing (council house or housing association property), you may benefit from heat pump installations through:

Social Housing Decarbonisation Fund (SHDF)

  • Provides funding to social housing providers for energy efficiency upgrades
  • Heat pumps are a key measure
  • No action required from you — your housing provider applies
  • You may be contacted by your housing association or council about planned upgrades

What Social Housing Tenants Should Do

  • Ask your housing provider if they have plans for heat pump installations
  • Check if your estate or area is included in SHDF-funded programmes
  • Report any heating problems or high energy bills to your housing officer

Who Definitely Will Not Get a Free Heat Pump

To be clear about who these schemes are not for:

  • Middle to higher income homeowners who do not receive means-tested benefits
  • Properties with good EPC ratings (A, B, or C) — unless other vulnerability criteria are met
  • New-build properties
  • Anyone not willing to have their property assessed

If you do not qualify for free installation, the BUS grant still provides £7,500 off your installation cost. In Scotland, the HES grant and loan can effectively eliminate your upfront cost even without means-tested benefits.

Avoiding Scams

The promise of "free" anything attracts scammers. Protect yourself by following these rules:

Red Flags

  • Unsolicited phone calls or door-knocking offering free heat pumps — legitimate schemes do not cold-call
  • Requests for upfront payment — free means free, you should never pay anything
  • Pressure to decide immediately — legitimate installers will give you time
  • Vague company details — ask for their company name, registration number, and MCS certification
  • Requests for bank details before any assessment — this is not normal

How to Verify

  • Contact the scheme directly (ECO4, Nest, HES) to verify any offer you receive
  • Check the installer's MCS certification on the MCS website
  • Ask your local council if the company is a recognised delivery partner
  • Check Companies House for the company's registration details

What If You Are Borderline Eligible?

If you are close to qualifying but not quite there, consider these options:

  • ECO4 Flex: Ask your council about referrals for households that are fuel-poor but not on qualifying benefits
  • Combination approach: Get insulation free through ECO4 and the heat pump through the BUS grant
  • Local schemes: Some councils have more flexible criteria than national programmes
  • Wait and check: Scheme criteria change periodically; you may become eligible in future

The Application Process: What to Expect

Regardless of which free scheme you apply through, the general process is similar:

  1. Initial contact: You call the scheme helpline or are referred by your council
  2. Eligibility check: Your benefits, income, and property details are reviewed
  3. Home assessment: An assessor visits your property to evaluate what measures are needed
  4. Recommendation: The assessor recommends appropriate measures (which may or may not include a heat pump)
  5. Approval: The scheme approves the work
  6. Installation: Approved contractors carry out the work at no cost to you
  7. Aftercare: You receive guidance on using your new heating system

The whole process can take anywhere from a few weeks to several months, depending on demand and the complexity of the work needed.

Real Cost Comparison: Free vs Subsidised vs Full Price

Here is what different homeowners might pay for a £12,000 air source heat pump installation:

  • ECO4 eligible: £0 (fully funded)
  • Nest eligible (Wales): £0 (fully funded)
  • Scotland HES grant + loan: £0 upfront, then £38/month interest-free for 10 years
  • BUS grant (England/Wales): £4,500 out of pocket
  • No grant: £12,000 out of pocket

Frequently Asked Questions

Can anyone get a free heat pump?

No. Free heat pump schemes are targeted at low-income and vulnerable households. You typically need to be receiving means-tested benefits or be referred by your council as fuel-poor.

Which scheme is best for a free heat pump?

ECO4 is the main route in England. In Wales, the Nest scheme is the primary option. In Scotland, Warmer Homes Scotland (through Home Energy Scotland) provides free installations.

I do not receive benefits. Can I still get a free heat pump?

Possibly, through ECO4 Flex. Your council can refer you if you are considered fuel-poor or vulnerable, even without qualifying benefits. Contact your local council to ask.

Are free heat pump offers from cold callers legitimate?

Almost always no. Legitimate schemes do not cold-call. If someone contacts you unsolicited offering a free heat pump, verify independently by calling the scheme directly.

How long does it take to get a free heat pump?

From initial enquiry to completed installation can take several weeks to several months. Demand is high and funding is allocated on a first-come, first-served basis in many cases.

What if I do not qualify for free installation?

The BUS grant provides £7,500 off for all homeowners in England and Wales. Scotland's HES scheme offers grants and interest-free loans totalling up to £15,000. See our complete grants guide.

Will my energy bills go down with a free heat pump?

In most cases, yes. Heat pumps are more efficient than old boilers, and if insulation is also installed, your energy demand will drop. The savings are especially significant for homes previously heated with oil or LPG. Check our running costs guide for realistic figures.

Can landlords get free heat pumps for rental properties?

Through ECO4, yes — if the tenant qualifies based on their benefits. The landlord may need to contribute in some cases. The BUS grant is also available to landlords.

Ready to check your eligibility? Contact your energy supplier about ECO4, call Nest on 0808 808 2244 (Wales), or call Home Energy Scotland on 0808 808 2282 (Scotland).
