Solar Panel Grants UK 2026: Every Scheme Explained
The question most homeowners ask when considering solar panels is: "Is there a government grant I can get?" The honest answer in 2026 is more nuanced than either a simple yes or no. There is no direct cash grant for solar panels available to homeowners in England — but there are several significant financial incentives that, taken together, can reduce your costs and boost your returns substantially.
This guide covers every legitimate scheme available in 2026, what you actually qualify for, and the myths you should ignore.
The Biggest "Grant" You Are Already Getting: 0% VAT
The single most valuable financial incentive for solar in the UK is not a grant at all — it is the zero rate of VAT applied to solar panel installations. Since April 2022, and made a permanent fixture from 2024, solar panels, batteries, and associated installation work are charged at 0% VAT rather than the standard 20%.
On a typical 4 kWp system costing £6,000, this saves you £1,200 compared with what you would have paid before the policy change. On a larger system with battery storage costing £12,000, the saving is £2,400. This is a real, automatic saving — no application required, no means testing, no waiting list.
The 0% rate applies to:
- Solar photovoltaic (PV) panels
- Solar battery storage systems
- Air-source and ground-source heat pumps
- Wind turbines
- Water source heat pumps
It does not apply to purely electrical work carried out separately from the renewable energy installation itself.
Smart Export Guarantee (SEG): Ongoing Income for Exported Power
The Smart Export Guarantee (SEG) is the UK government's scheme that requires licensed electricity suppliers with more than 150,000 customers to offer homeowners a tariff for electricity they export to the grid from their solar panels. It replaced the Feed-in Tariff (FiT), which closed to new applicants in 2019.
Unlike the old Feed-in Tariff, SEG rates are not set by the government — each supplier sets its own rate, and these change regularly. As of early 2026, rates from major suppliers look roughly like this:
| Supplier | SEG Tariff Name | Export Rate | Notes |
|---|---|---|---|
| Octopus Energy | Outgoing Octopus Fixed | ~15p/kWh | Fixed rate, widely available |
| Octopus Energy | Outgoing Octopus Agile | Variable (2p–40p+) | Half-hourly export pricing, can be very lucrative at peak times |
| British Gas | Solar Export | ~12p/kWh | Available to existing BG customers |
| EDF Energy | Smart Export | ~12p/kWh | Requires smart meter |
| E.ON Next | Next Export | ~12p/kWh | Fixed rate |
| Scottish Power | Solar Generation | ~10p/kWh | Available to SP customers |
You do not need to be a customer of the supplier to access their SEG tariff for exports — though some suppliers do give preferential rates to existing customers. You must have an MCS-certified installation and a smart meter (or compatible export meter) to receive SEG payments.
For a 4 kWp system exporting around 1,700 kWh per year, SEG income at 15p/kWh amounts to approximately £255 per year. Over 20 years, that is £5,100 in export income alone — without accounting for further rises in export rates if wholesale prices increase.
How to Register for SEG
- Ensure your installation is MCS-certified (your installer handles this at point of installation)
- Ensure you have a smart meter capable of recording export (your supplier can arrange this)
- Apply to your chosen supplier's SEG tariff — this is usually done online
- You can switch SEG suppliers independently of your import tariff supplier
ECO4: Free Solar Panels for Eligible Households
The Energy Company Obligation (ECO4) is a government scheme that requires large energy suppliers to fund energy efficiency improvements in low-income and vulnerable households. It is the one route through which some UK homeowners can genuinely receive solar panels at no cost.
To qualify for ECO4-funded solar panels in England, Wales, or Scotland, you generally need to:
- Receive certain means-tested benefits (such as Universal Credit, Pension Credit, Child Tax Credit, or income-related Employment and Support Allowance)
- Live in a property with a low EPC rating (typically E, F, or G)
- Own your home, or have a landlord willing to participate
ECO4 is primarily focused on insulation and heating systems, and solar panels are not always available under the scheme — it depends on what measures best improve your property's EPC rating. However, in homes where insulation measures alone cannot raise the EPC sufficiently, solar PV can be included.
To find out whether you are eligible, contact your energy supplier directly, or use the government's ECO4 eligibility checker. Be cautious of cold-calling companies claiming to offer "free solar panels under a government scheme" — many are not legitimate ECO4 installers.
Home Energy Scotland: Grants and Loans
Homeowners in Scotland have access to a more generous support framework than those in England, through the Home Energy Scotland (HES) programme funded by the Scottish Government.
In 2026, Home Energy Scotland offers:
- Interest-free loans of up to £15,000 for energy efficiency improvements, including solar panels and battery storage
- Cashback grants of up to £2,500 for certain measures (eligibility varies by measure and income)
- Additional support for households in rural areas and island communities
To access HES funding, contact Home Energy Scotland directly on 0808 808 2282 or through the official website. An adviser will carry out a free assessment and advise on eligible measures.
Boiler Upgrade Scheme: Not for Solar, But Worth Knowing
The Boiler Upgrade Scheme (BUS) provides grants of £7,500 for air-source heat pumps and £7,500 for ground-source heat pumps. It does not cover solar panels directly, but many homeowners install solar alongside a heat pump to offset the running costs. If you are considering a combined system, the BUS grant can make the overall package considerably more affordable.
For more details on combining solar with a heat pump, see our guide to solar panels and heat pumps together.
Local Authority and Council Schemes
A number of local councils run their own solar support schemes, often using UK Shared Prosperity Fund money or Warm Homes Fund grants. These vary considerably by area and change frequently. It is worth contacting your local council's energy or sustainability team to ask what is currently available. Some councils have run schemes offering subsidised group-buying programmes for solar, where a council-approved installer offers reduced rates to residents who sign up collectively.
What You Do NOT Get: The Myths Debunked
Myth 1: "There Is a £5,000 Government Grant for Solar in England"
There is no direct cash grant for solar panel installation available to homeowners in England in 2026. The Renewable Heat Incentive closed years ago. The Feed-in Tariff closed in 2019. The only current financial incentives are the 0% VAT rate, the Smart Export Guarantee, and ECO4 for eligible households. Anyone claiming to offer you a "government grant" for solar in England that covers a large portion of installation costs is almost certainly misleading you.
Myth 2: "Free Solar Panels — You Pay Nothing"
The "free solar panels" offers that circulated in the early 2010s were rent-a-roof schemes, where a company installed panels on your roof for free, took all the Feed-in Tariff income, and left you with only modest bill savings. These schemes made sense when FiT rates were high; they are essentially extinct now that FiT has closed. Any company still marketing "free solar panels" should be approached with extreme caution. Read the small print very carefully — you may be signing a lease or agreement that ties you to the company for 20–25 years and complicates any future sale of your home.
Myth 3: "Solar Pays for Itself in Under Two Years"
Realistic payback periods for solar in the UK are 4–7 years for solar only, and 7–10 years for solar with battery storage. Anyone claiming a two-year payback is almost certainly using unrealistic assumptions about electricity prices, self-consumption rates, or both. See our full guide to solar panel costs and payback for a detailed analysis, including what system sizes cost.
Making the Most of Available Support
The most financially efficient approach in 2026 is to:
- Use the 0% VAT rate automatically by choosing an MCS-certified installer
- Register for the best available SEG tariff — Octopus Energy's export tariffs are consistently competitive
- If in Scotland, contact Home Energy Scotland before committing to a purchase
- If on benefits and in a low-EPC property, investigate ECO4 eligibility before spending anything
- Consider pairing solar with a heat pump to access the £7,500 Boiler Upgrade Scheme grant for the heating element
Bottom line: There is no free lunch for solar panel installation in England in 2026, but the combination of 0% VAT and ongoing SEG payments is genuinely valuable. For eligible households, ECO4 and (in Scotland) HES grants remain the most significant direct financial support available.
