Energy bills have turned into one of the largest burdens on UK family budgets, and in response to this problem, the UK government has developed an increasing network of grants, subsidies, and tax credits aimed at reducing heating costs and utility charges for households. Unfortunately, Government Energy Grants UK is not a single program, but rather a general term covering a minimum of 8 separate programs, each with its own criteria, funding source, and deadline.
This guide aims to provide all the information related to each Government Energy Grants UK scheme, such as what exactly they cover, who qualifies for assistance, the process of applying, and more.
Why the Government Funds These Schemes
<cite index=”9-1″>According to DESNZ figures from 2024, around 13.4% of UK households — roughly 3.49 million homes in England alone — are in fuel poverty</cite>. To address this, alongside the UK’s broader net-zero commitments, <cite index=”9-1″>the government has committed £13.2 billion to the Warm Homes Plan announced in the Spring Budget 2026, intended to eventually replace ECO4 from 2027 onwards</cite>. The result is a set of overlapping grants that between them touch almost every major home improvement: insulation, heating, solar, batteries, and EV charging.

The Full List of UK Energy Grants in 2026
ECO4 (Energy Company Obligation)
ECO4 remains the largest and most established Government Energy Grants UK scheme. It’s a government-backed programme requiring large energy suppliers to fund energy efficiency improvements in eligible homes, and it takes a “whole house” approach, meaning a single property can receive multiple upgrades in one go, potentially lifting its EPC rating from a low “G” all the way up to a “C.”
Who qualifies: Households on qualifying means-tested benefits with an EPC rating of D or below. Typical qualifying benefits include Universal Credit and Pension Credit, or a household income below roughly £36,000.
What it covers: Loft and cavity wall insulation, boiler replacements, and first-time central heating systems through Government Energy Grants UK, worth an average of £4,200 per household.
Timeline: Runs until 31 December 2026.
Wider access via LA Flex: The Local Authority Flexible Eligibility scheme extends ECO4-style support to low-income and vulnerable households who don’t receive income-related benefits, so it’s worth checking even if you don’t tick the standard benefits box under Government Energy Grants UK.
The Warm Homes Plan
This is the government’s flagship long-term programme and the successor to much of what ECO4 currently does. <cite index=”5-1″>Backed by up to £15 billion in funding, it aims to upgrade up to 5 million homes by 2030</cite>, making it, on paper, the largest energy efficiency initiative in British history.
It has two main practical strands for homeowners:
- Warm Homes: Local Grant — <cite index=”8-1″>launched in April 2025 and funded until March 2028, delivered by local authorities in England for homes with an EPC rating of D, E, F or G</cite>.
- Warm Homes Fund — <cite index=”5-1″>intended to offer low- and 0%-interest loans for solar panels, batteries, heat pumps and insulation, open to homeowners regardless of income, though the government hasn’t yet confirmed exactly when these loans will launch</cite>.
Boiler Upgrade Scheme (BUS)
For anyone replacing a gas or oil boiler with a heat pump, BUS is the main funding route.
- Who qualifies: <cite index=”7-1″>No means testing at all</cite> — <cite index=”9-1″>you simply need to own your property and hold a valid EPC</cite>.
- What it covers: <cite index=”9-1″>£7,500 towards the cost of an air source or ground source heat pump</cite>, <cite index=”10-1″>with the homeowner covering the difference between the grant and the total installation cost</cite>.
- How to apply: <cite index=”9-1″>Your installer handles the application for you</cite> as part of the quote process.
- Timeline: <cite index=”7-1″>Currently funded until March 2028</cite>.

GBIS previously offered <cite index=”4-1″>free or subsidised loft and cavity wall insulation to homes in lower council tax bands with a low EPC rating, without requiring benefits</cite>. <cite index=”2-1″>However, the scheme closed to new measures on 31 March 2026</cite>, and its referral route on GOV.UK is now shut. Anyone who would previously have used GBIS is directed to ECO4, LA Flex, or the Warm Homes: Local Grant instead.
Smart Export Guarantee (SEG)
SEG isn’t a one-off grant but an ongoing payment mechanism for households with solar panels.
- How it works: <cite index=”8-1″>Suppliers pay you for surplus electricity your system exports to the grid; Ofgem requires larger suppliers to offer a tariff above zero but doesn’t set the actual rate</cite>, so shopping around matters.
- What you need: <cite index=”8-1″>An MCS-certified (or Flexi-Orb equivalent) installation and a smart or export meter</cite>.
- A caveat: <cite index=”8-1″>Rates can change with roughly a month’s notice, so treat any advertised figure as indicative until you check live tariffs at the point of installation</cite>.
0% VAT on Energy-Saving Materials
Arguably the simplest scheme, because there’s no application process at all.
- What it covers: <cite index=”1-1″>0% VAT applies to solar panels, battery storage, heat pumps, and insulation installations, running until March 2027</cite>, and can <cite index=”1-1″>save roughly four figures on a typical home solar system</cite>.
- How to claim it: Nothing to apply for — your installer simply charges the reduced rate automatically on qualifying work.
OZEV EV Chargepoint Grant
Not a heating or insulation grant, but frequently grouped with home energy support because it’s administered similarly.
- Who qualifies: <cite index=”1-1″>As of 2026, the grant is restricted to renters, landlords, and flat owners with eligible off-street parking — homeowners who own a house with a driveway or garage no longer qualify</cite>.
- Requirements: <cite index=”1-1″>Off-street parking allocated to your property, an OZEV-approved charger, and proof of an electric or plug-in hybrid vehicle</cite>.
- What it covers: <cite index=”1-1″>Up to £500 towards an approved home charger</cite>.
- How to apply: <cite index=”1-1″>Your installer applies on your behalf and submits the application before work starts</cite>.
Warm Home Discount
A more direct form of support aimed at bills rather than building work. <cite index=”9-1″>It’s worth £150 off electricity bills</cite> and <cite index=”2-1″>is typically applied automatically for qualifying households, with guidance for 2026 showing a deadline extension to October 2026</cite>.

Support isn’t uniform across the UK. <cite index=”8-1″>ECO4 and 0% VAT apply UK-wide, but the Warm Homes: Local Grant is England-only, while Scotland, Wales and Northern Ireland run their own devolved schemes with different names, budgets and rules</cite>. <cite index=”1-1″>In Scotland, Home Energy Scotland administers the BUS-equivalent grant and interest-free loans</cite>, while <cite index=”5-1″>Wales runs the Warm Homes Nest Scheme, offering free energy-efficient improvements, including solar panels, to low-income households and those in deprived communities</cite>. On top of national schemes, <cite index=”7-1″>many local councils run additional grants through LA Flex provisions and their own local energy efficiency programmes</cite>, so it’s worth contacting your council’s housing or energy team directly.
How Much Could You Actually Get?
Figures vary by household, but as a rough guide across the main schemes:
- ECO4: average £4,200 per household in free improvements
- BUS: £7,500 towards a heat pump
- OZEV: up to £500 towards an EV charger
- Warm Home Discount: £150 off electricity bills
- 0% VAT: typically a four-figure saving on a solar and battery installation
- SEG: an ongoing income stream from solar exports, varying by supplier and usage
Because most schemes can be combined, the realistic total for an eligible low-income household undertaking a full retrofit — insulation, a heat pump, and solar — can run into five figures once every relevant grant and discount is applied.
Who Typically Qualifies
Eligibility depends on the specific scheme, but a few recurring factors determine most outcomes:
- Benefits and income: ECO4 and most local authority routes are built around means-tested benefits like Universal Credit or Pension Credit, or a household income threshold.
- EPC rating: Homes rated D and below are the main target for insulation and heating grants.
- Ownership status: BUS requires homeownership; OZEV now favours renters, landlords, and flat owners instead.
- Location: England, Scotland, Wales, and Northern Ireland each administer some elements differently, particularly around insulation and heating support.
- Vehicle ownership: Relevant only for OZEV, which requires proof of an electric or plug-in hybrid vehicle.
If you’re unsure where you stand, the fastest way to find out is the free eligibility checker on GOV.UK, which cross-references your postcode, benefits, and property type against the schemes currently open.
How to Apply: A Practical Walkthrough
- Get or check your EPC. Search “Find an energy certificate” on GOV.UK. If yours is more than 10 years old, or doesn’t exist, you’ll likely need a new one before most schemes will consider your application.
- Gather proof of benefits or income. Universal Credit, Pension Credit, and other qualifying benefit confirmations are the main eligibility documents for ECO4 and LA Flex.
- Run the GOV.UK eligibility checker. This gives a fast first read on which schemes are worth pursuing for your postcode and circumstances.
- Contact your local council. Especially for LA Flex or Warm Homes: Local Grant, your council’s housing or energy team may have routes not listed nationally.
- Get quotes from MCS-certified installers. For BUS, ECO4 measures, and OZEV, installers apply for the grant on your behalf as part of the quote — you generally don’t submit paperwork to the government yourself.
- Verify approval before work begins. A reputable installer confirms grant approval before starting any work, so there’s no risk of being billed for something you expected to be funded.
- Ask about stacking. <cite index=”7-1″>Most grants can be combined — for example, ECO4 insulation alongside a BUS heat pump grant, the Warm Home Discount, and SEG income from solar exports</cite> — so always ask what else you might qualify for at the same time.
Staying Safe
The scale of funding involved makes this a popular area for scams. Cold callers or door-knockers offering “free government grants” in exchange for upfront payment or bank details are never legitimate. Genuine schemes are accessed through GOV.UK, your local council, or an installer you’ve chosen and vetted yourself — never through an unsolicited approach.
What’s the difference between a “grant” and a “scheme”?
In practice, they’re used interchangeably. Some, like ECO4 and GBIS, fully fund the cost of work for eligible households. Others, like BUS, provide a fixed contribution toward a higher cost. And some, like 0% VAT, aren’t cash grants at all but reductions applied automatically at the point of sale.
Is there one single application for all grants?
No. There’s no universal portal that applies for every scheme at once. The GOV.UK eligibility checker is the closest thing to a single starting point, but individual applications are typically handled by your installer or local council depending on the scheme.
Can homeowners with a decent income still get help?
Yes, in some cases. BUS has no means testing, and the upcoming Warm Homes Fund loans are intended to be available regardless of income. ECO4 and the Warm Homes: Local Grant, however, are generally aimed at lower-income or higher fuel-poverty-risk households.
What happened to the Great British Insulation Scheme?
It closed to new applications on 31 March 2026. If you were hoping to use GBIS, you should now look at ECO4, LA Flex, the Warm Homes: Local Grant, or supplier-led insulation offers instead.
Do renters get access to any of these grants?
Some do. Certain ECO4 and Warm Homes: Local Grant measures extend to private and social renters, usually with landlord permission required. OZEV’s EV charger grant is now specifically targeted at renters and flat owners rather than homeowners.
How long do I have to apply?
It depends on the scheme. ECO4 is due to close at the end of December 2026, while BUS and the Warm Homes: Local Grant are funded until March 2028, and the 0% VAT rate runs until March 2027. Because funding is often allocated on a first-come, first-served basis, applying sooner rather than later is generally recommended.
Are these schemes the same across the whole UK?
No. ECO4 and 0% VAT apply UK-wide, but England, Scotland, Wales, and Northern Ireland each run their own additional or replacement schemes, particularly for insulation and heating support, so the exact name and process can differ depending on where you live.
What should I do if I think I’ve been targeted by a scam?
Stop any communication, don’t share personal or financial details, and report it via Action Fraud or Citizens Advice. Then go directly to GOV.UK or your local council to check what you’re genuinely entitled to.
Conclusion
“Government energy grants” is really an umbrella term for a set of distinct programmes, each aimed at a different slice of the population and a different type of home improvement. ECO4 and the Warm Homes: Local Grant are the main routes for lower-income households seeking free insulation, heating, or solar. BUS offers a substantial, non-means-tested contribution toward heat pumps for any homeowner. 0% VAT quietly reduces costs for almost everyone installing solar, batteries, heat pumps, or insulation. SEG and the Warm Home Discount then help on the ongoing bills side once the upgrades are in.
Because eligibility rules and closing dates shift — GBIS’s closure in March 2026 being the most recent example — the most reliable way to navigate this landscape is to start with your EPC rating, check the official GOV.UK eligibility tool, and speak to an accredited installer who can confirm exactly which grants apply to your home and handle the paperwork on your behalf. For many households, more than one scheme applies at once, which is where the real savings tend to add up.
This article is for general information only. Grant amounts, eligibility criteria, and scheme end dates can change — always verify current details with GOV.UK, your local authority, or an accredited installer before making financial decisions.
