UK Solar Panel Grants in 2026: What Funding Is Really Available?
With energy prices remaining volatile and the UK continuing its transition towards net-zero, many homeowners and businesses are looking for ways to reduce the cost of installing solar panels.
While there is no single nationwide “free solar” scheme for most households, a range of government-backed incentives, tax reliefs, and supplier payments continue to make solar far more affordable in 2026.
At Sustainable Energy Engineering Limited, we help homeowners and businesses across the North East understand exactly what funding is available — and how to maximise the return on their investment.
0% VAT on Solar Panels & Battery Storage (Valid Until March 2027)
The UK government continues to apply a 0% VAT rate to domestic solar panel and battery installations, making this one of the most valuable incentives available in 2026.
- Introduced: April 2022
- Current End Date: March 2027
- Eligibility: Domestic properties in England, Scotland and Wales
- Applies To: Solar panels, batteries, inverters and installation
For most homeowners, this reduces installation costs by 20% compared to pre-2022 pricing.
How to Claim: Automatically applied by MCS-certified installers — no separate application required.
Smart Export Guarantee (SEG) – Ongoing in 2026
The Smart Export Guarantee allows households and businesses to receive payments for excess electricity exported to the grid.
- Start Date: January 2020
- Status: Ongoing
- Eligibility: MCS-certified system, smart meter, grid connection
- Typical Rates (2026): 8p – 20p per kWh (supplier dependent)
With improved export tariffs and smart metering, SEG has become more valuable in recent years — particularly for larger systems and homes without batteries.
How to Apply: Register directly with your chosen energy supplier after installation.
ECO4 Scheme (Closing Phase – Ends March 2026)
The Energy Company Obligation (ECO4) scheme remains available in early 2026 but is now in its final phase.
- End Date: March 2026
- Eligibility: Low-income households or vulnerable residents
- Funding: Partial or full funding in qualifying cases
ECO4 is means-tested and not available to most households. Eligibility is based on income, benefits, and property efficiency.
How to Apply: Through participating energy suppliers or approved installers.
Local Authority & Regional Support Schemes
In 2026, many councils and housing associations continue to operate regional retrofit and decarbonisation programmes.
These schemes are often funded through:
• Social Housing Decarbonisation Fund (SHDF)
• Home Upgrade Grant (HUG)
• Local Net-Zero Programmes
Availability varies by region and is usually limited to social housing, landlords, or fuel-poor households.
How to Apply: Through your local authority or housing provider.
Green Finance & Low-Interest Energy Loans
Although traditional grants are limited, many lenders now offer green finance products for solar installations.
These include:
• Low-interest home improvement loans
• Green mortgages
• Renewable energy finance packages
• Installer-backed payment plans
These options allow homeowners to spread costs while still benefiting from immediate energy savings.
Do “Free Solar” Schemes Still Exist in 2026?
For most homeowners, genuinely “free” solar installations are now rare.
They are usually limited to:
• Social housing projects
• Vulnerable households
• Council-led retrofit schemes
• Special pilot programmes
Private “rent-a-roof” schemes largely disappeared after the Feed-in Tariff closed in 2019.
How Much Can You Save in 2026?
Typical annual savings for UK homeowners in 2026:
• Without battery: £500 – £850 per year
• With battery: £700 – £1,200+ per year
• SEG income: £100 – £300+ per year
Actual savings depend on system size, usage patterns, tariff selection, and battery capacity.
Frequently Asked Questions
Are there still government grants for solar panels?
Most direct grants have ended, but VAT relief, SEG payments, and targeted schemes remain available.
Can I get solar panels for free?
Only in limited cases through council or social housing schemes. Most homeowners now self-fund.
Do I need planning permission?
Most domestic systems fall under permitted development unless you live in a listed building or conservation area.
Is solar still worth it without grants?
Yes. Rising energy prices and improvements in battery technology mean most systems still pay for themselves within 5–9 years.

UK Solar Grants in 2026
