UK Energy Grants Explained: What You Can Actually Get

If you've ever tried to figure out what energy grants you're entitled to in the UK, you'll know the feeling.

It's confusing. It changes constantly and even people in the industry struggle to keep up.

To be honest — even as a Domestic Energy Assessor, it can feel like grants, grants, grants… and no clear answers.

So if you're a homeowner or landlord trying to navigate it, you're not alone.

Here's the reality:

There is serious money available to improve your property, sometimes covering a large portion of the cost and in some cases, fully funding upgrades.

But most people either:

• Don't realise what they're eligible for
• Apply too late
• Fall outside of the strict guidelines for access
• Give up because it's super complicated

And that's where opportunities get missed.

Most UK energy grants are tied, in some way, to your EPC rating.

As a general rule:

• EPC A–C — Less likely to qualify
• EPC D–G — More likely to qualify

That's because funding is targeted at lower performing homes where improvements will have the biggest impact.

So before anything else, you need to know where your property currently sits.

Here are some of the key schemes currently available or evolving:

ECO4 Scheme (Energy Company Obligation)

Run under obligations placed on major energy suppliers, ECO4 has funded:

• Insulation upgrades
• Heating system improvements
• Whole-house retrofit measures

It has primarily targeted:

• Low-income households
• Vulnerable residents
• Properties with EPC ratings of D and below

ECO4 is phasing out, but similar schemes are continuing to evolve.

Warm Homes Plan (Replacing ECO4)

The UK Government has signalled a move toward a broader “Warm Homes” approach, focusing on:

• Lower-income households (typically under £36k income or on benefits)
• Improving energy efficiency and reducing fuel poverty
• Whole-property upgrades rather than single measures

Eligibility will still be means tested in most cases.

Boiler Upgrade Scheme (BUS)

This is one of the most widely accessible grants right now.

It offers:

• £5,000 towards an air source heat pump
• £7,500 towards a ground source heat pump

The scheme is run by Ofgem and is available to many homeowners in England and Wales.

Important to note:

• It doesn't fully cover the install, you'll still need to contribute
• Your property needs to be suitable (insulation, system design, etc.)

Local Authority Flex (LA Flex)

This allows local councils to extend ECO style funding to households that don't meet strict national criteria.

It often targets:

• Households with health conditions
• Low to moderate incomes
• EPC D–G properties

Eligibility varies depending on your local authority. To find your eligibility you can analyse your property with Ecograde.ai.

Solar Group Buying Schemes

Some councils in the UK offer “Solar Together”-style schemes, where:

• Panels are purchased in bulk
• Install costs are reduced
• Approved installers are pre-selected

These aren't always grants but they can significantly lower upfront costs.

Other Targeted Schemes

Depending on your situation, you may also come across:

• First Time Central Heating Grants (for homes without existing systems)
• Health linked schemes (targeting vulnerable households)
• Regional or pilot funding programmes

The challenge?

There's no single, simple list and schemes change frequently.

The system isn't designed to be simple.

Each scheme has:

• Different eligibility criteria
• Different funding rules
• Different timelines
• Different application processes

And just when you get your head around one…

It changes.

If you're trying to access funding, keep it simple:

• Check your EPC rating first
• Understand your household eligibility (income, benefits, health factors)
• Look at multiple schemes — not just one
• Apply early — funding is often limited

Eligibility isn't always black and white and different schemes assess things differently.
