The increasing cost of energy has resulted in UK residents seeking means to reduce their bills and become energy efficient. The positive aspect of this situation is that there are various schemes funded by the government, energy companies, and councils that will help homeowners get Free Home Energy Grants UK to improve their houses’ efficiency through various measures like insulation, installation of a new boiler, installation of solar panels, and many other solutions without any payment from the customer.
Here you can find an explanation of the different Free Home Energy Grants UK schemes available in 2026, who is eligible for each program, how much money a homeowner can get from each program, the process of getting the grant, and some answers to popular questions related to Free Home Energy Grants UK.
Why These Grants Exist
<cite index=”9-1″>The UK government has committed £13.2 billion to the Warm Homes Plan announced in the Spring Budget 2026, intended to replace ECO4 from 2027</cite>. This reflects the scale of the problem: <cite index=”9-1″>Department for Energy Security and Net Zero (DESNZ) figures put the number of English households in fuel poverty at around 3.49 million, roughly 13.4% of all households</cite>. Energy grants exist to tackle two goals at once — reducing household bills and cutting the carbon emissions that come from heating draughty, poorly insulated homes.
The Main Schemes Available in 2026
1. ECO4 (Energy Company Obligation)
ECO4 is one of the largest Free Home Energy Grants UK schemes and the biggest and best-known domestic energy efficiency scheme in the country. It requires large energy suppliers to fund improvements in qualifying homes and takes a “whole house” approach, meaning a single household could receive multiple upgrades at once, potentially lifting a home’s Energy Performance Certificate (EPC) rating from a low “G” up to a “C.”
Who qualifies: ECO4 is aimed squarely at low-income and vulnerable households. Eligibility generally requires being on a qualifying means-tested benefit and having an EPC rating of D or below. Typical qualifying benefits include Universal Credit and Pension Credit, or in some cases a household income below roughly £36,000.
What it covers: Free insulation, boiler replacements, solar panels, heat pumps, and first-time central heating installations through Free Home Energy Grants UK. On average, households receive improvements worth around £4,200, according to Ofgem-sourced figures, though the true value depends on what your home needs.
Timeline: <cite index=”7-1″>ECO4 is scheduled to run until 31 December 2026</cite>.
Local Authority Flexible Eligibility (LA Flex): If you don’t receive a qualifying benefit but are still struggling with energy costs, it’s still worth checking LA Flex. <cite index=”5-1″>This is an extension of ECO4 that allows local authorities to fund low-income and vulnerable households who don’t receive income-related benefits</cite>, widening the net considerably.

2. The Warm Homes Plan and Warm Homes: Local Grant
Launched to eventually take over from ECO4, <cite index=”5-1″>the Warm Homes Plan is backed by up to £15 billion in funding to upgrade up to 5 million homes by 2030</cite>, which the government has billed as the largest energy efficiency scheme in British history.
One strand already up and running is the Warm Homes: Local Grant. <cite index=”8-1″>It launched in April 2025 and is funded to run until March 2028, so it will continue after ECO4 closes</cite>. <cite index=”8-1″>It’s delivered by local authorities, who set some of the detail themselves, but the core eligibility broadly requires an English home with an EPC rating of D, E, F or G</cite>.
A second element, the Warm Homes Fund, is aimed at a much wider group. <cite index=”5-1″>It’s intended to offer low- and 0%-interest loans to install solar panels, batteries, heat pumps, and insulation, open to homeowners regardless of income — though the government has not yet confirmed exactly when these loans will become available</cite>.
3. Boiler Upgrade Scheme (BUS)
| Boiler Upgrade Scheme (BUS) | Details |
|---|---|
| Purpose | If you’re replacing a fossil-fuel boiler with a heat pump, BUS is the scheme to know about. |
| Who qualifies | Unlike ECO4, BUS is not means-tested. The Boiler Upgrade Scheme has no means testing at all, though you do need to own your property and hold a valid Energy Performance Certificate to apply. |
| What it covers | BUS provides £7,500 towards the cost of an air source or ground source heat pump, and you pay the difference between the grant and the total installation cost. |
| How to apply | You don’t apply directly. Your MCS-certified installer handles the grant application on your behalf as part of the quote and installation process. |
| Timeline | BUS is currently funded to run until March 2028, giving homeowners a longer runway than ECO4. |
4. Great British Insulation Scheme (GBIS) — Closed to New Applicants
If you’ve read about GBIS elsewhere, it’s worth knowing that the referral route has now shut. <cite index=”2-1″>The Great British Insulation Scheme closed to new measures on 31 March 2026</cite>. Previously, <cite index=”4-1″>it offered free or subsidised loft and cavity wall insulation to homes in lower council tax bands with a low EPC rating, without requiring benefits</cite>. Anyone who would previously have used GBIS is now directed toward ECO4, LA Flex, or the Warm Homes: Local Grant instead.
5. Smart Export Guarantee (SEG)
If you have solar panels, SEG isn’t a grant in the traditional sense but an ongoing payment for the electricity you don’t use yourself.
How it works: <cite index=”8-1″>Energy suppliers pay you for surplus electricity you export back to the grid, though Ofgem only requires larger suppliers to offer a SEG tariff above zero — it doesn’t set the actual price</cite>, so rates vary considerably between suppliers. <cite index=”8-1″>To claim SEG you’ll normally need an MCS-certified (or Flexi-Orb equivalent) installation and a smart or export meter</cite>. Because tariffs can change with roughly a month’s notice, it’s worth comparing live rates before assuming a headline figure will apply once your system is installed.
6. 0% VAT on Energy-Saving Materials
This is one of the broadest and simplest savings, because there’s nothing to apply for.
Who qualifies: Essentially all homeowners installing qualifying energy-saving measures. <cite index=”1-1″>The 0% VAT rate covers solar panels and battery storage installations, and also extends to heat pumps and insulation, running until March 2027</cite>. On a typical solar and battery system, this alone <cite index=”1-1″>can save roughly four figures</cite> compared to paying standard VAT.
How to apply: No application is needed — your installer simply charges 0% VAT on the qualifying parts of the job.
7. OZEV EV Chargepoint Grant
Although aimed at electric vehicle charging rather than heating, OZEV is often bundled into “home energy grant” searches.
Who qualifies: <cite index=”1-1″>The grant is now 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 in 2026</cite>. <cite index=”1-1″>You’ll need 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, checking eligibility during the quote process and submitting the application before work starts</cite>.

A smaller but still valuable scheme aimed at helping with bills directly rather than funding home improvements. <cite index=”9-1″>It’s worth £150 off electricity bills</cite>, and is <cite index=”2-1″>automatically applied for most qualifying households, with 2026 guidance showing a deadline extension to October 2026</cite>.
Devolved Nation Schemes
Support differs 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″>Scottish residents typically go through Home Energy Scotland for BUS-equivalent grants and interest-free loans</cite>, while <cite index=”5-1″>the Welsh Government’s Warm Homes Nest Scheme provides free energy-efficient home improvements, including solar panels, to low-income households and those in deprived communities</cite>.
Who Typically Qualifies — A Quick Summary
Eligibility depends heavily on which scheme you’re looking at, but a few factors come up again and again:
- Benefits status: Universal Credit, Pension Credit, and other means-tested benefits are the main gateway into ECO4 and many local authority schemes.
- EPC rating: Homes rated D, E, F, or G are typically the target for insulation and heating grants; better-rated homes are less likely to qualify for whole-house schemes.
- Household income: Some routes, including parts of the Warm Homes Plan, use an income threshold rather than a specific benefit.
- Homeownership status: BUS requires you to own the property. OZEV, by contrast, is now aimed at renters, landlords, and flat owners rather than homeowners with their own driveway.
- Location: Whether you’re in England, Scotland, Wales, or Northern Ireland changes which specific scheme name applies to you, even where the underlying support is similar.
Because eligibility criteria shift between schemes — and schemes themselves open, close, or get replaced — the safest way to check where you personally stand is to use the government’s official eligibility checker on GOV.UK, or speak to an MCS-certified installer, who will typically check what you qualify for as part of a no-obligation quote.

- Check your EPC rating. Search “Find an energy certificate” on GOV.UK and enter your postcode. If your EPC is more than 10 years old, or you don’t have one, you’ll likely need a new assessment before applying to most schemes.
- Identify your qualifying benefits or income band. Have proof of any means-tested benefits (Universal Credit, Pension Credit, and similar) ready, since this is the main eligibility test for ECO4 and LA Flex.
- Use an eligibility checker. GOV.UK offers a free checker for several schemes. Enter your postcode and answer a short set of questions about your benefits, income, and property.
- Get quotes from accredited installers. For BUS, ECO4, and OZEV, you generally don’t apply directly to the government — an MCS-certified (or Flexi-Orb, for some insulation measures) installer submits the paperwork for you as part of the quote and installation process.
- Confirm funding before work starts. Reputable installers will confirm your grant is approved before any work begins, so you’re never left paying for something you expected to be funded.
- Keep records. Save your EPC certificate, any benefit confirmation letters, and correspondence with your installer, in case you need to query your grant later or apply for a second measure.
- Check for stacking opportunities. <cite index=”7-1″>Most grants can be combined — for example, pairing ECO4 insulation with a BUS heat pump grant, the Warm Home Discount, and SEG earnings from solar exports</cite>, so it’s worth asking your installer or council which combinations apply to your home.
A Word of Caution
Because these schemes involve genuinely large sums of money, they attract scammers who cold-call or knock on doors claiming to offer “free government grants.” Legitimate schemes are applied for through GOV.UK, your local council, or accredited installers — never through unsolicited calls asking for upfront payment or bank details. If in doubt, go directly to GOV.UK or contact your local authority’s housing or energy team to verify a scheme before sharing any personal information.
Are these grants really free, or do I have to pay anything?
It depends on the scheme. ECO4 and the Warm Homes: Local Grant measures are typically fully funded for eligible households, meaning you pay nothing. BUS, by contrast, is a contribution — it covers £7,500 towards a heat pump, and you pay any remaining cost. The Warm Home Discount and 0% VAT reduce your costs directly rather than funding work outright.
Can I apply for more than one grant at the same time?
Yes. Most schemes are designed to be combined. A common combination is insulation through ECO4, a heat pump through BUS, the Warm Home Discount on your bills, and SEG payments if you also have solar panels.
Do I need to be on benefits to get a grant?
Not always. ECO4 generally requires a qualifying means-tested benefit, but BUS has no means testing at all, and LA Flex and some Warm Homes Plan routes use household income or EPC rating instead of benefit status. It’s worth checking every scheme rather than assuming you’re excluded.
What if I rent rather than own my home?
Some schemes, including parts of ECO4 and the Warm Homes: Local Grant, extend to private and social renters, though your landlord’s permission is usually required for any physical work. OZEV’s EV charger grant is now specifically aimed at renters, landlords, and flat owners rather than owner-occupiers with their own driveway.
How long will these schemes be available?
This varies and is worth checking regularly, since dates can move. As things stand, ECO4 is expected to run until the end of 2026, BUS is funded until March 2028, the 0% VAT rate on solar, batteries, heat pumps and insulation runs until March 2027, and the Warm Homes: Local Grant is funded until March 2028. The Great British Insulation Scheme has already closed to new applicants.
How do I avoid scams?
Only apply through GOV.UK, your local council, or an accredited installer you’ve chosen yourself. Be wary of anyone who contacts you unprompted claiming you’ve been “selected” for a free grant, especially if they ask for payment or personal financial details upfront.
What’s the difference between a grant and the Smart Export Guarantee?
A grant typically funds or subsidises the cost of installing equipment like insulation, a heat pump, or solar panels. SEG is different — it’s an ongoing payment from your energy supplier for surplus electricity your solar panels export to the grid, and it continues for as long as you’re signed up, rather than being a one-off payment.
Will these grants improve my home’s value as well as my bills?
Many of the improvements funded by these schemes — insulation, a modern heating system, solar panels — tend to improve a property’s EPC rating, which can be a factor buyers and mortgage lenders increasingly consider, alongside the more immediate benefit of lower monthly energy costs.
Conclusion
There is no single “free home energy grant” in the UK — instead there’s a set of overlapping schemes, each targeting different needs, income levels, and types of home improvement. ECO4 and the Warm Homes: Local Grant are the main routes for low-income households seeking free insulation, heating, or solar; BUS offers a substantial contribution toward heat pumps for any homeowner regardless of income; 0% VAT quietly reduces the cost of solar, battery, and insulation installs for almost everyone; and SEG and the Warm Home Discount help on the bills side once upgrades are in place.
Because eligibility rules, funding pots, and end dates change relatively often — GBIS closing its referral route in March 2026 being a recent example — the most reliable approach is to start with the official GOV.UK eligibility checker, confirm your EPC rating, and speak to an MCS-certified installer who can check what you qualify for and handle the paperwork on your behalf. Taken together, these schemes can meaningfully cut both the upfront cost of making a home more efficient and the ongoing bills that follow, but only if you know which door to knock on — and increasingly, for many households, more than one grant applies at once.
