Increased energy prices have resulted in millions of British families searching for ways of reducing their energy costs. Thankfully, UK Energy Grants 2026 include another influx of financial assistance from both the government and private companies, with old programs such as ECO4 being supplemented by new programs that have emerged within the framework of the £15 billion Warm Homes Scheme. Regardless of whether you are a homeowner, a private tenant, a landlord, or a pensioner with limited means, chances are high that you qualify for some grant, discount, or subsidy.
The following guide reviews all of the UK Energy Grants 2026, including eligibility criteria, amount of money available, and application process. This guide also provides you with answers to the most frequently asked questions prior to applying for energy grants.
Why UK Energy Grants Matter in 2026
Energy efficiency grants exist for three main reasons: to reduce fuel poverty, to cut national carbon emissions, and to help the UK meet its long-term climate targets. For individual households, though, the appeal is far more immediate — grants can knock thousands of pounds off the cost of insulation, heating upgrades, solar panels, and EV charging points, while lowering monthly bills for years afterward.
2026 is a particularly important year because several schemes are shifting shape. The Great British Insulation Scheme (GBIS) has already closed to new applicants, ECO4 is scheduled to wind down at the end of December, and the Warm Homes Plan is stepping in as the government’s flagship successor programme. Meanwhile, the Boiler Upgrade Scheme (BUS) has been given long-term funding security, and the 0% VAT relief on energy-saving materials remains in place until spring 2027. Understanding this shifting landscape now can help you time your application to lock in the best possible support.

The Main UK Energy Grant Schemes in 2026
1. Energy Company Obligation (ECO4)
ECO4 is the fourth phase of a long-running obligation placed on large energy suppliers to fund energy-efficiency improvements for low-income and vulnerable households. It remains one of the most generous UK Energy Grants 2026 schemes available, often covering the full cost of measures like loft insulation, cavity wall insulation, boiler replacements, and even solar panels for qualifying homes.
Eligibility: Households that receive means-tested benefits such as Universal Credit, Pension Credit, Income Support, income-based Jobseeker’s Allowance, or income-related Employment and Support Allowance, and whose property has an Energy Performance Certificate (EPC) rating of D, E, F, or G, are typically eligible. Local Authority Flexible Eligibility (LA Flex) widens this further, allowing councils to approve households that don’t receive benefits but are still considered low-income or vulnerable, for example due to age or a health condition made worse by a cold home.
How to apply: You do not apply to ECO4 directly. Instead, you contact an approved energy supplier or a registered installer, who checks your eligibility and submits the application as part of the installation quote. The process can move quickly once eligibility is confirmed, sometimes within a couple of weeks from the installation application.
Deadline: ECO4 is due to close on 31 December 2026, after which the Warm Homes Plan is expected to take over funding for similar measures. Anyone who thinks they may qualify for UK Energy Grants 2026 is advised to start the process well before the deadline, since applications submitted close to year-end may not be processed in time.
2. The Warm Homes Plan
Announced at the start of 2026, the Warm Homes Plan is the government’s flagship successor to previous efficiency schemes and is billed as the largest home energy efficiency initiative in British history, with up to £15 billion in funding earmarked to upgrade as many as five million homes by 2030. It is designed to fund insulation and low-carbon heating, primarily for lower-income and fuel-poor households, delivered through local authorities and regional partners.
Eligibility: As the plan continues to roll out through local authorities, the exact measures and criteria vary by region and are still being finalised in many areas. Homeowners can check directly through the government’s eligibility checker, while renters need to apply through their local authority.
How to apply: Homeowners fill out an initial eligibility screening online; if you qualify, you’ll be asked for contact details, and your application is passed to your local authority. Renters must go through their council directly, since work on rented properties usually also requires landlord permission.
3. Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme is the headline grant for households looking to move away from fossil-fuel heating systems and toward heat pumps. It provides a substantial upfront capital grant — commonly cited at £7,500 — that reduces the cost of installing an air source or ground source heat pump.
Eligibility: You generally need to own the property, have a working heating system to replace, and a building fabric that’s reasonably efficient (or be willing to improve it as part of the same project). Unlike ECO4, BUS is not restricted to low-income households — most owner-occupiers switching from oil, gas, or electric heating can apply.
How to apply: The grant is applied for on your behalf by an MCS-certified installer as part of your quote. You never claim it separately, and the discount is simply deducted from your final bill.
Funding security: BUS funding has been confirmed through to 2029/30 as part of the wider Warm Homes Plan funding envelope, meaning there’s no immediate cliff edge for households planning a heat pump installation later in the decade.
4. Great British Insulation Scheme (GBIS)
GBIS offered free or heavily subsidised loft, cavity wall, and (in some cases) solid wall insulation. It was open to a broader range of households than ECO4, including many outside the benefits system, provided their council tax band and EPC rating met the criteria.
Status in 2026: New applications for GBIS closed on 31 January 2026, and the scheme itself ended in March 2026. If you missed the window, your best options now are ECO4 (while it remains open), LA Flex, or your local Warm Homes Plan route.
5. Home Upgrade Grant (HUG)
HUG is specifically targeted at homes that are not connected to the mains gas grid — often rural properties relying on oil, LPG, or electric heating. It can fund a package of measures including insulation, air source heat pumps, and in some cases solar panels.
Eligibility: Properties off the gas grid with a household income under roughly £36,000, and an EPC rating of D to G, are typically considered.
How to apply: Applications go through your local authority, since HUG (like the Warm Homes Plan more broadly) is delivered at a local level with council-specific criteria and timelines.

If you install solar panels, SEG allows you to earn money by exporting surplus electricity back to the grid. Rates vary between energy suppliers and are currently in the low single-digit pence per kWh, but a typical household solar system can still generate a meaningful annual credit.
Eligibility: Any property with a qualifying solar installation and a licensed electricity supplier offering an SEG tariff can take part. There is no application “grant” as such — instead, you choose an SEG tariff from a supplier (which does not have to be your existing energy supplier) once your system is installed and MCS-certified.
How to apply: Compare SEG tariffs from participating suppliers after installation, then register your system with the chosen provider. SEG is expected to continue indefinitely, with rates evolving as more suppliers enter the market.
7. OZEV EV Chargepoint Grant
The Office for Zero Emission Vehicles (OZEV) grant helps cover the cost of installing a home electric vehicle charger. In 2026, this grant is restricted to renters, landlords, and flat owners with dedicated off-street parking — homeowners of houses with their own driveway or garage are no longer eligible for OZEV, though they can still benefit from 0% VAT if the charger is bundled with other energy-saving work.
Eligibility: You need off-street parking allocated to your property, an OZEV-approved charger, and proof you own or lease an electric or plug-in hybrid vehicle.
How to apply: Your installer handles the application as part of the quote process, checking eligibility before work begins and submitting the claim before installation.
Deadline: The scheme is currently set to close on 31 March 2027, with no successor yet announced.
8. 0% VAT on Energy-Saving Materials
This isn’t a cash grant, but it’s one of the most valuable pieces of support available in 2026: solar panels, battery storage, heat pumps, and insulation installed in residential properties currently attract 0% VAT rather than the standard rate. This is applied automatically by the installer — there’s no separate claim to make.
Deadline: The zero rate is due to end in March 2027, after which the previous 5% reduced rate is expected to return. If you’re paying for any of these measures out of pocket, scheduling work before that date locks in the saving.
9. Warm Home Discount
The Warm Home Discount gives eligible households a one-off reduction on their electricity bill, typically £150, paid automatically or credited to a prepayment meter. It reopens each autumn for that winter’s payments.
Eligibility: You generally need to be receiving certain means-tested benefits and have your name (or your partner’s) on the electricity bill. Most eligible households are identified automatically and simply need to watch for a confirmation letter; no application is usually required unless your circumstances have changed.
10. Winter Fuel Payment
This annual payment helps pensioners cover heating costs over winter. Eligibility depends on age and, since recent reforms, on income — those with an income above a set threshold still receive the payment but have it recovered through the tax system. Most eligible people receive it automatically; a claim is only needed if you don’t usually receive other qualifying benefits.
General Eligibility Factors Across Schemes
While every scheme has its own rules, most UK energy grants weigh a combination of the following:
- Income and benefits status — receiving Universal Credit, Pension Credit, or similar means-tested benefits opens the door to the most generous schemes.
- Property type and tenure — some grants are for owner-occupiers only, others specifically target renters, landlords, or off-gas-grid homes.
- EPC rating — a rating of D, E, F, or G is the standard threshold for insulation-focused schemes.
- Council tax band — used by some regional schemes as a proxy for household circumstances.
- Local authority discretion — LA Flex and Warm Homes Plan delivery both allow councils to set additional local criteria, so eligibility can genuinely differ by postcode.
How to Apply: A Step-by-Step Approach
- Check your eligibility online. Start with the official government eligibility checker or your local council’s energy pages before contacting installers.
- Get an EPC assessment if you don’t already have one. Many schemes require a current EPC rating to confirm eligibility.
- Choose an MCS-certified installer. For solar panels and heat pumps in particular, certification is mandatory for any grant funding — quotes from non-certified installers won’t qualify.
- Let the installer handle the paperwork. With almost every scheme on this list, the installer submits the grant application as part of your quote. You should never need to pay an upfront “application fee” to a third party.
- Gather supporting documents. Have proof of income, benefit award letters, and proof of homeownership or tenancy ready, since these are commonly requested during the eligibility check.
- Confirm details before work starts. Grants are typically approved and locked in before installation begins, not afterward, so make sure everything is confirmed in writing first.
- Keep records. Retain your grant confirmation, EPC certificate, and installer invoices in case you need to demonstrate compliance later, particularly if you’re a landlord working toward EPC targets.
Practical Tips for 2026
- Don’t wait for the Warm Homes Plan if you already qualify for ECO4. ECO4 closes at the end of 2026, while Warm Homes Plan local rollouts are still being finalised in many areas.
- Time paid-for work before March 2027 to keep the 0% VAT saving if you’re funding solar, battery, heat pump, or insulation work yourself.
- Combine grants where possible. A heat pump installation, for example, might combine BUS funding with SEG income if solar is installed at the same time, and landlords can use grant-funded work to reduce how much of their own money counts toward EPC compliance costs.
- Apply early for GBIS-style schemes, since funding on some regional programmes is allocated first-come, first-served rather than guaranteed to everyone eligible.
- Be wary of unsolicited callers or door-to-door offers. Legitimate grants are applied for through registered installers or your local council — never through someone demanding payment to “process” an application.
Do I have to pay back an energy grant?
No. Genuine government-backed energy grants, including ECO4, BUS, and Warm Homes Plan funding, are not loans and do not need to be repaid, provided the work is carried out as agreed.
Can I apply for more than one grant at the same time?
Yes, in many cases. For example, a household installing a heat pump might receive the Boiler Upgrade Scheme grant while also benefiting from 0% VAT and, if solar is installed too, income from the Smart Export Guarantee.
What if I don’t receive any benefits — can I still get help
Possibly. Local Authority Flexible Eligibility (LA Flex) and some Warm Homes Plan routes are designed for low-income or vulnerable households who don’t receive means-tested benefits. It’s worth checking with your council even if you don’t tick every standard box.
Do renters qualify for energy grants?
Many do, though the process usually goes through the local authority rather than a direct national application, and landlord permission is generally required before work can start in a rented property.
Is the Boiler Upgrade Scheme only for gas boiler replacements?
No — it applies to replacing most fossil-fuel heating systems, including oil and LPG boilers, with an air source or ground source heat pump, and it’s open to most owner-occupiers, not just low-income households.
What happens when ECO4 ends in December 2026?
The Warm Homes Plan is expected to take over funding for similar measures from January 2027, though full local eligibility details are still being confirmed in many areas as of mid-2026.
Do I need an EPC before applying
For most schemes, yes. A current EPC rating is one of the main ways eligibility is assessed, so it’s worth arranging one early if you don’t already have a valid certificate.
Are solar panel grants still available in 2026
Direct solar-panel grants are more limited than a few years ago, but eligible low-income households can still receive fully funded solar installations through ECO4 or HUG, and everyone benefits from 0% VAT and SEG export payments regardless of income.
How long does the application process usually take?
It varies by scheme, but ECO4 applications can move from initial contact to completed installation in as little as two weeks once eligibility is confirmed, while Warm Homes Plan and local authority routes can take longer due to local processing times.
Where can I check the most current information?
Scheme rules, funding levels, and deadlines can change with little notice, so it’s worth confirming current details on GOV.UK or with your local council before committing to any work.
Conclusion
The UK’s energy grant landscape in 2026 is more layered than it has ever been, with established schemes like ECO4 running alongside newer efforts like the Warm Homes Plan, and long-standing support such as the Boiler Upgrade Scheme, Smart Export Guarantee, and 0% VAT relief still very much in play. The right combination of grants depends heavily on your income, your property type, and where you live, since local authorities have real discretion over how schemes like LA Flex and the Warm Homes Plan are delivered on the ground.
The most important practical takeaway is timing. ECO4 closes at the end of December 2026, the 0% VAT rate is due to end in March 2027, and the OZEV chargepoint grant closes shortly after — so if you think you might be eligible for any of these, it’s worth starting the eligibility check now rather than waiting. For everything else, from the Boiler Upgrade Scheme through to the Warm Home Discount, funding is either open-ended or secured for several more years, giving you more flexibility to plan around your own budget and circumstances.
Because rules and funding levels can shift quickly, always verify the latest criteria on GOV.UK or with your local council before starting any work, and only ever apply through an approved installer or official government channel — never through a third party asking for payment up front to “process” your grant.
