Key Solar Panel Grants And Incentives Available In 2025
Let’s explore the solar panel grants and incentives available in 2025:
1. Energy Company Obligation (ECO4)
Aimed at low-income households and those living in less energy-efficient homes, ECO4 is a major source of green energy funding in the UK in 2025.
- Up to 100% of solar panel installation costs
- Available to households receiving certain benefits (e.g., Universal Credit, Pension Credit)
- Targets EPC-rated D to G homes
- Runs until March 2026
This is one of the most comprehensive solar electricity grant options available and is ideal for those who are eligible for support.
2. Warm Homes Plan (Local Authority Grant)
The Home Upgrade Grant for solar panels, known locally as the Warm Homes Plan, supports low-income and privately rented properties in England:
- Fully funded solar systems for qualifying homes
- Also supports insulation and other energy upgrades
- EPC D–G homes and renters included
Contact your local authority to check availability and participate.
3. Solar Together
Not eligible for means-tested support? No problem. Solar Together is a group-buying scheme open to everyone. You register your interest, and vetted solar installers compete to offer the best bulk price.
- Save an average of 30–35% on installation costs.
- Open to homeowners and small businesses
- Widely available across UK councils
If you don’t qualify for free solar panels from the government solar schemes in the UK, this is an excellent way to save significantly.
4. 0% VAT on Solar Installations
As part of the UK’s push to decarbonise homes, the government has scrapped 0% VAT on domestic renewable installations:
- Applies to solar panels, inverters, and batteries (when installed together)
- Valid until April 2027
- Reduces the solar panel cost, which the UK government grant would otherwise need to cover
This incentive is automatically applied through your MCS-certified installer—no application is necessary.
5. Smart Export Guarantee (SEG)
If you have already installed solar panels with the Smart Export Guarantee (SEG), you earn 20–40p per kWh by exporting unused electricity to the grid.
- Available to all solar owners (systems up to 5MW)
- Payments vary by supplier
- Complements other solar panel subsidies in the UK options
You’ll need a smart meter and an SEG-compliant energy provider to participate.
