ECO4 Solar Panels Eligibility UK
ECO4 Solar Panels Eligibility UK 2026 – Do You Qualify for Free Solar?
If you’re on qualifying benefits or a low income and your home has a poor energy rating, you could get solar panels installed for absolutely nothing under the ECO4 scheme. Here’s everything you need to know — quickly and without the jargon.
The energy bills have been brutal in recent years, and the idea of solar panels might feel like something that’s only for people with money to spare. But here’s what most people don’t realise — if you’re on certain benefits or have a lower income and your home isn’t very energy efficient, you could get solar panels fitted for absolutely free through the UK government’s ECO4 scheme. Not a loan. Not a discount. Free.
I’ve put this guide together to take all the confusing government speak and turn it into something you can actually use. By the end of this, you’ll know whether you qualify, what you’d get, and exactly how to move forward — before the scheme closes on 31 December 2026.
ECO4 has been extended to 31 December 2026, but there’s a real risk of the funding running out before then. Once energy suppliers hit their annual targets, they stop taking applications — even if it’s not December yet. If you think you might qualify, don’t sit on it.
What Is ECO4 and Why Does It Exist?
ECO4 stands for Energy Company Obligation, fourth phase. Rather than being a traditional government grant paid from tax revenues, it’s a legal obligation placed by the government on large energy suppliers — any company with more than 150,000 customers. That includes the big names you’ll recognise: British Gas, EDF, Octopus Energy, OVO, E.ON Next, and Scottish Power, among others.
Under ECO4, those suppliers are required to fund energy efficiency improvements for low-income and vulnerable households. The whole thing is overseen by Ofgem, the UK’s independent energy regulator. The scheme has a total budget of around £4 billion across its four-year run from April 2022 to December 2026.
The main goal is to tackle fuel poverty — that deeply frustrating situation where people spend a significant chunk of their income on energy and still struggle to heat their homes. Solar panels are one of the measures ECO4 can fund, alongside insulation, heat pumps, and heating system upgrades.
ECO4 isn’t the only route to help with solar costs, either — if it turns out you don’t qualify, it’s worth checking our full UK solar panel grants hub for every other current scheme, 0% VAT included.

📅 How Far Through Is ECO4? (April 2022 → December 2026)
What Solar Panels Can You Get Under ECO4?
ECO4 typically funds a standard residential solar photovoltaic (PV) system. It’s worth knowing upfront that solar panels aren’t always the first measure approved — insulation usually comes first, and solar is more commonly approved for homes with electric heating or that are off the gas grid. But when it is funded, it’s fully covered. Here’s what that looks like in practice:
| Feature | What You Get Under ECO4 |
|---|---|
| Typical System Size | 3–4 kWp (approximately 10–14 panels) |
| Your Cost | £0 — 100% funded by your energy supplier |
| Market Value of Installation | £5,000–£8,000 per eligible household |
| Annual Bill Savings | £600–£900/year (at Q2 2026 grid rate of 24.5p/kWh) |
| Smart Export Guarantee (SEG) | Earn 12–15p/kWh for surplus electricity you export to the grid |
| Battery Storage | Rarely covered under ECO4; more likely under the Warm Homes Plan from 2027 |
| Installer Requirements | Must be MCS-certified and TrustMark-approved |
| Covered in Scotland & Wales | ✅ Yes — same eligibility criteria apply |
| Covered in Northern Ireland | ❌ No — ECO4 does not extend to Northern Ireland |
What Does ECO4 Cover Overall?
Funded for homes with electric heating or off-gas properties — 100% cost covered
Loft, cavity wall, and solid wall insulation — the most commonly approved measure
Air source and ground source heat pumps for eligible properties off the gas network
Efficient replacement boilers when replacing a broken or non-condensing system
Modern heating controls and smart thermostats to reduce wasted energy
New doors, windows (in most cases), battery storage, or second homes
Keen on battery storage even though ECO4 rarely funds it directly? Our Solar Battery Storage UK guide breaks down real 2026 installed costs, so you know what you’d be paying for on top of any ECO4-funded panels.
ECO4 Solar Panels Eligibility – Am I Eligible?
Right, this is the bit you really need. There are two parallel ways to qualify for ECO4 — and you need to meet at least one household condition AND the property condition. Let me break both down clearly.
Benefits-Based Route (Help to Heat)
You or someone in your household receives one of the qualifying benefits listed below, and your home has an EPC rating of D, E, F, or G. This is the most straightforward route — if you tick both boxes, you’re very likely to be approved.
LA Flex Route (Local Authority Flex)
You don’t receive qualifying benefits, but your household income is under £31,000 per year, or you (or someone you live with) has a health condition that makes you vulnerable to cold. Your local council refers you to a supplier. Availability varies by area.
Qualifying Benefits for ECO4 Solar Panels (Route 1)
You qualify through the benefits-based route if anyone in your household currently receives any one of the following. You don’t need to receive all of them — just one is enough, alongside the EPC requirement.
| Benefit | Income Threshold / Notes | Qualifies for ECO4? |
|---|---|---|
| Universal Credit | Income must be under £2,000/month after housing costs per UC statement | ✓ Yes |
| Pension Guarantee Credit | Automatic eligibility — no additional income threshold | ✓ Yes |
| Pension Savings Credit | As above — automatic eligibility | ✓ Yes |
| Income Support | No additional income threshold required | ✓ Yes |
| Income-based Jobseeker’s Allowance (JSA) | Income-based JSA only — not contribution-based JSA | ✓ Yes |
| Income-related ESA | Income-related Employment & Support Allowance only | ✓ Yes |
| Child Tax Credit | Household income under £16,480/year (some sources quote updated thresholds — confirm at application) | ✓ Yes |
| Working Tax Credit | No additional income threshold | ✓ Yes |
| Child Benefit | Income thresholds apply: from £31,000 for a single adult with one child, rising with additional children | ✓ Yes (with thresholds) |
| Housing Benefit | No additional income threshold required | ✓ Yes |
| Contribution-based JSA or ESA | The contribution-based versions do not qualify for ECO4 | ✗ No |
| PIP / DLA / Attendance Allowance | These alone don’t qualify, but may support an LA Flex referral for vulnerable households | ↗ Via LA Flex only |
If you’re a pensioner, you could qualify through Pension Credit, Housing Benefit, Attendance Allowance (via LA Flex), or simply through the LA Flex income route if your household income is under £31,000. Pensioner households are given priority by many suppliers.
EPC Rating Requirements – Does Your Home Qualify?
As well as receiving a qualifying benefit, your home needs the right EPC (Energy Performance Certificate) rating. The EPC is a score that tells you how energy-efficient your home is, from A (very efficient) to G (very inefficient). You can check yours for free at find-energy-certificate.service.gov.uk.
EPC Rating Chart – Which Ratings Qualify for ECO4?
* Homeowners need EPC D–G. Private tenants typically need EPC E–G. Homes rated A, B, or C are considered already energy efficient and don’t qualify for ECO4.
* If your EPC is more than 10 years old, you may need a new assessment. These cost £60–£120 and are sometimes arranged by the installer as part of the ECO4 application.
Property Type Requirements
| Who You Are | Minimum EPC Required | Extra Conditions |
|---|---|---|
| Owner-Occupier | EPC D, E, F or G | Must be your main residence |
| Private Tenant | EPC E, F or G (typically) | Landlord must give written permission for installation work |
| Social Housing Tenant | Separate schemes apply | Contact your housing association or council directly |
| Second Home / Holiday Let | ❌ Not eligible — must be your main residence | |
If you’re privately renting, you’ll need your landlord’s written consent before any installation can happen. The good news is that both parties benefit — you get lower bills, and your landlord gets an improved EPC rating, which matters more and more for rental compliance under the Minimum Energy Efficiency Standards (MEES). For the fuller picture — including what your options are if your landlord says no — see our guide on whether renters can get solar panels in the UK.
How to Apply for ECO4 Solar Panels – Step by Step
The process is much more straightforward than most people expect. You don’t need to deal with mountains of paperwork — the installer does the heavy lifting. Here’s how it works from start to finish:
Check Your Eligibility
Confirm that you (or someone in your household) receives a qualifying benefit, and that your home has an EPC rating of D–G. Check your EPC free of charge at find-energy-certificate.service.gov.uk. If your property isn’t listed, you may need a fresh assessment.
Contact a Registered ECO4 Installer or Your Energy Supplier
Get in touch with a TrustMark-registered ECO4 installer, or contact your energy supplier directly. Many installers offer a free eligibility check online in under five minutes — our own Find an Installer tool is a quick way to compare MCS-certified installers in your area if you’d rather start there. If you’re going the LA Flex route, contact your local council instead — they’ll refer you to a participating supplier.
Home Survey
A qualified energy surveyor visits your home to check EPC details, roof condition, shading, wiring suitability, and whether solar panels make practical sense for your property. This survey is free and doesn’t commit you to anything.
Application Submitted to the Energy Supplier
The installer submits your application on your behalf. Approval typically takes 2–4 weeks. You don’t need to do any paperwork yourself — the retrofit coordinator handles all of it. The whole process from initial contact to installation can take as little as a few weeks in some cases.
Installation Day
Certified installers fit the solar panels — usually in a single day for a standard residential system. You’ll receive full warranty documentation, a smart export guarantee (SEG) guide, and practical advice on getting the most from your new panels.
Only ever use installers who are TrustMark-registered and MCS-certified. If anyone asks you to pay upfront, sign over your SEG payments, or pressures you into making quick decisions — walk away. Rogue operators have exploited ECO4 applicants with substandard installations. Check the TrustMark register before committing to anyone.
What Could You Actually Save? Real Numbers
Free solar panels are brilliant on their own, but the ongoing financial benefit is just as important. Here’s an honest look at what a typical UK household gets from a 4kWp solar system in 2026 — and if you want figures matched to your own roof rather than a national average, our Solar Panel Calculator and SEG Income Estimator will run the numbers for you.
Annual Financial Benefits — 4kWp Solar Panel System (2026 Estimates)
Based on UK grid price of 24.5p/kWh (Q2 2026) and Octopus SEG export rate of 15p/kWh
Individual savings will vary based on usage, roof orientation, system size, and tariff. Estimates use Q2 2026 data. SEG payments depend on your chosen export tariff.
Saved per year on electricity by using power generated on your roof
Earned annually by selling surplus electricity back to the grid
Solar panels typically push your home up one to two EPC bands

What Happens After ECO4? The Warm Homes Plan
There’s been a lot of noise about what replaces ECO4, so let me clear it up. The earlier plan to launch an “ECO5” was cancelled in 2025. In its place, the government has announced the Warm Homes Plan — described as the biggest energy efficiency programme in British history, with close to £15 billion in investment running through to 2030.
The key difference is how it’s funded. ECO4 was funded through a levy on energy bills (energy suppliers paid for it). The Warm Homes Plan will be funded directly from central government — which suggests broader scope and potentially higher grant values per household. But the detail on eligibility and how to apply hasn’t been confirmed yet.
Trying to work out which of the current schemes actually applies to you — ECO4, LA Flex, the Warm Homes: Local Grant, or just the universal 0% VAT rate? Our UK Solar Grant & VAT Savings Checker runs through all of them in one place, so you’re not left guessing.
🌿 Warm Homes Plan — Expected from January 2027
The government’s confirmed successor to ECO4, with nearly £15 billion committed through 2030. Broader scope than ECO4, directly government-funded, and expected to cover a wider range of measures per household (up to £15,000 per property).
Covered measures (indicative — full details expected late 2026):
The government’s own technical documents state the Warm Homes Plan’s capital delivery route is planned “from 2027/28 onwards.” Since ECO4 ends 31 December 2026, there could be several months where neither scheme is available. If you qualify for ECO4 today, applying now — rather than waiting — is the right call. The Warm Homes Plan’s eligibility rules and contractor capacity won’t be confirmed until late 2026 at the earliest.
ECO4 vs Warm Homes Plan — What’s the Difference?
| Feature | ECO4 (Now) | Warm Homes Plan (2027+) |
|---|---|---|
| Funding Source | Energy supplier levy | Central government |
| Solar Panels | ✓ Covered (conditions apply) | ✓ Expected to be covered |
| Battery Storage | Rarely funded | Expected to be included |
| Max Grant Value | ~£10,000 typical | Up to £15,000 per property (indicative) |
| Total Budget | ~£4 billion (since 2022) | ~£15 billion (through 2030) |
| Status | Open NOW — closes Dec 2026 | Not yet open — expected Jan 2027 |
| Application | Via energy supplier or installer | Via local council (Warm Homes Local Grant already live for some areas) |

Frequently Asked Questions
These are the questions I get asked most often about ECO4 solar panels. The answers below are also included in structured data (JSON-LD) for Google’s FAQ rich results in search.
To qualify for ECO4 solar panels in the UK, you need to meet two conditions simultaneously. First, you or someone in your household must receive a qualifying benefit — Universal Credit, Pension Credit (Guarantee or Savings), Income Support, income-related ESA or JSA, Child Tax Credit, Working Tax Credit, Child Benefit, or Housing Benefit. Second, your home must have an EPC rating of D, E, F, or G. If you don’t receive qualifying benefits, you may still be eligible through the Local Authority Flex (LA Flex) route if your household income is under £31,000 per year, or if you’re vulnerable due to a health condition. The property must be in England, Scotland, or Wales — ECO4 does not cover Northern Ireland.
Yes, ECO4 is still available in 2026 for solar panels. The scheme was extended to 31 December 2026. However, as that deadline approaches, energy suppliers are filling their annual quotas and funding is allocated on a first-come, first-served basis. Eligible households can receive 100% of installation costs — a typical 4kWp system worth £5,000–£8,000. There may be a gap of several months between ECO4 closing and the Warm Homes Plan successor scheme beginning in 2027, so applying as soon as possible is strongly recommended. If your application is in the pipeline before 31 December 2026, your installation can complete after that date.
To qualify for ECO4 solar panels, your home must have an EPC (Energy Performance Certificate) rating of D, E, F, or G. Homes rated A, B, or C are already considered energy efficient and don’t qualify for ECO4. Homeowners need at least EPC D, whilst private tenants typically need EPC E or below. You can check your current EPC rating free of charge using your postcode at find-energy-certificate.service.gov.uk. If your EPC is more than 10 years old, you’ll need a fresh assessment — these cost £60–£120 and are sometimes arranged by the installer as part of the ECO4 application process.
