Why to Choose ECO4 Solar Panels Grant in UK
With the ECO4 scheme, UK residents can be eligible for solar panel grants that take care of the entire installation cost.
Presently, solar panels, batteries, and renewable products are subject to 0% VAT, which provides a discount of as much as £2,850 to the household on a 4kW solar system.
With the Smart Export Guarantee (SEG), you might make £80 to £170 annually by selling back the excess energy to the National Grid.
Warm Homes Scheme (April 2025) will again fund new solar installations for social housing tenants, lower-income families, and private renters in the UK.
Why Install Solar?
Solar power is sustainable, renewable, and makes homes more energy independent. Solar panels installed in the UK enable you to reduce energy bills, protect against increasing prices, and improve your home's EPC rating.
How Much Could You Save with Solar Panels?
Save £2,850 with the 0% VAT bonus on qualifying solar systems and energy-saving materials – until March 2027.
The 0% VAT is on solar panels, batteries, and some renewable energy products.
Using the average price of a 4kW solar PV system and battery, you could save thousands.
This lower VAT rate is available to any UK homeowner who buys qualifying energy-saving materials and equipment.
How to get Eligible?
To be eligible for the 0% VAT on solar panels in the UK, both installation and property must meet certain requirements:
The installation and product should be done in conjunction with each other as part of a single project
Other improvements can also be done, including insulation, but the central point of the job needs to be energy-saving materials such as solar panels.

Who Qualifies for Free Solar Panels UK Government Grants?
There are free solar panel grants throughout the UK under the ECO4 scheme from April 2022 to March 2026. With £4 billion funding, the scheme finances low-income and fuel-poor households. Successful applicants can get £7,000 to £20,000+ funding, paying for up to 100% of the cost of solar installations.
You will need to be qualified based on:
Household income
Government benefits you receive
Your property's EPC rating (traditionally D–G properties)
The Warm Homes Plan (2025) will offer extra financial help towards energy-efficient improvements for renters, residents of social housing, and low-income families.
Smart Export Guarantee (SEG)
UK homes can generate income through surplus solar power export back to the National Grid under the Smart Export Guarantee (SEG).
To be eligible, your renewable system (solar PV, wind, hydro, or micro-CHP) needs to be SEG compliant.
Your installation should feature a smart meter to record exported electricity.
Payments can only be made by licensed SEG energy suppliers (SEG Licensees).
If your installation qualifies, you might receive £80–£170 per year by selling excess electricity back to the National Grid, in addition to bill savings.
Working – How Do Solar PV Panels Work?
Solar PV panels create renewable electricity in four main processes:
Light Absorption
Solar panels collect energy in the form of sunlight through silicon photovoltaic (PV) cells.
Electricity Generation
The light generates an electric field, generating direct current (DC).
AC Power Conversion
The DC electricity is converted by an inverter into alternating current (AC) and supplies power to your home appliances.
Export to the Grid
Any remaining electricity is exported to the National Grid via the Smart Export Guarantee.
Get Free Solar Panels via UK Grants
Depending on the scheme, you could be eligible for fully or half-funding solar panels in the UK. Through the ECO4 grant, you could get free solar panel installation or contribute only a discounted amount. In Scotland, we offer grants of up to £10,000, which can help finance a typical 4kW solar PV system.
With an appropriate solar installation, homes would make between £730 and £1,110 per year in return, depending on usage and system size.
