Why to Choose ECO4 Solar Panels Grant in UK
Through the ECO4 scheme, UK households may qualify for solar panel grants that cover the full cost of installation.
Currently, there is 0% VAT on solar panels, batteries, and renewable energy products, giving households a discount of up to £2,850 on a 4kW solar system.
Through the Smart Export Guarantee (SEG), you could earn £80 to £170 per year by selling excess energy back to the National Grid.
The Warm Homes Plan (from April 2025) will provide further funding for new solar installations for social housing tenants, lower-income households, and renters across the UK.
Why Choose Solar?
Solar energy is renewable, sustainable, and helps households become more energy independent. Installing solar panels in the UK allows you to lower energy bills, safeguard against rising costs, and enhance your home’s EPC rating.
How Much Could You Save with Solar Panels?
Save up to £2,850 with the 0% VAT incentive on eligible solar systems and energy-saving materials – available until March 2027.
0% VAT applies to solar panels, batteries, and certain renewable energy products.
Based on the average cost of a 4kW solar PV system and battery, you could save thousands.
Any UK homeowner who purchases qualifying energy-saving materials and equipment is eligible for this reduced VAT rate.
How to get Eligible?
To qualify for the 0% VAT rate on solar panels in the UK, both your property and the installation must meet specific eligibility requirements:
The installation and product must be carried out together as part of one project.
Additional improvements such as insulation may also be included, but the main focus of the work must be on energy-saving materials like solar panels.

Who Qualifies for Free Solar Panels UK Government Grants?
Free solar panel grants are available across the UK under the ECO4 scheme, which runs from April 2022 to March 2026. With £4 billion funding, the scheme supports low-income and fuel-poor households. Eligible applicants can receive £7,000 to £20,000+ in funding, covering up to 100% of solar installation costs.
To qualify, you must meet requirements based on:
Household income
Government benefits received
Your property’s EPC rating (typically D–G homes)
The Warm Homes Plan (from 2025) will provide additional financial support for energy-efficient upgrades to renters, social housing residents, and low-income households.
Smart Export Guarantee (SEG)
With the Smart Export Guarantee (SEG), UK households can earn income by exporting surplus solar energy back to the National Grid.
To qualify, your renewable system (e.g., solar PV, wind, hydro, or micro-CHP) must meet SEG standards.
Your setup must include a smart meter capable of recording exported electricity.
Only licensed SEG energy suppliers (SEG Licensees) can make payments.
If your system meets the criteria, you could earn £80–£170 annually by exporting unused electricity back to the National Grid, in addition to your bill savings.
How do the Solar PV Panels Work?
Solar PV panels generate renewable electricity in four key stages
Light Absorption
Solar panels absorb sunlight using silicon photovoltaic (PV) cells.
Electricity Generation
The absorbed light creates an electric field, producing direct current (DC).
Conversion to AC Power
An inverter converts the DC electricity into alternating current (AC), which powers your home appliances.
Export to the Grid
Any unused electricity is exported back to the National Grid through the Smart Export Guarantee.
Get Free or Funded Solar Panels Through UK Grants
Depending on the scheme, you may qualify for fully or partially funded solar panels in the UK. Under the ECO4 grant, eligible households can benefit from free solar panel installation or pay only a reduced contribution. In Scotland, we provide grants of up to £10,000, helping cover the cost of a standard 4kW solar PV system.
With the right solar setup, households could generate an annual return of £730 to £1,110, depending on energy usage and system size.
