Financial Assistance Available for Solar Panel Installation in 2025

0% VAT on Solar Panels and Batteries Until March 2027

A major cost saver for UK residents and businesses is the temporary 0% VAT rate on solar panels, battery storage systems, and certain energy-saving devices. Introduced by the UK government to promote renewable energy adoption, this VAT relief has been active since April 1, 2022, and will continue through March 31, 2027.

Who qualifies?All UK homeowners and businesses purchasing and fitting solar panels or battery storage systems.
Possible savings:This exemption can reduce costs by the VAT amount, potentially saving up to around £2,850 on a typical 4kW solar installation including batteries, depending on system pricing.
How to claim?No separate application is needed; certified solar installers usually apply this VAT rate during installation.

This VAT exemption helps decrease the initial cost of solar equipment and encourages wider adoption across the UK.

Smart Export Guarantee (SEG) – Earn Income for Surplus Solar Power

The Smart Export Guarantee (SEG), effective since January 1, 2020, allows solar panel owners to get payments for surplus electricity exported back to the national grid.

Eligibility:UK property owners with solar panels, compatible battery storage, and a smart meter.
Potential payments:Earnings vary depending on the energy company and tariff chosen and may range roughly between £80 and £170 per year.
How to participate:Homeowners can compare SEG tariffs from different energy providers and sign up with the one offering the best rate to receive payments for exported electricity.

Through SEG, solar panel owners can offset their energy bills with extra income or credits.

ECO4 Scheme – Financial Aid for Solar Installations for Eligible Low-Income Households (Ends March 2026)

The Energy Company Obligation 4 (ECO4) scheme helps low-income households fund solar energy installations.

Who qualifies?Households with qualifying incomes (annual incomes below about £31,000) or individuals whose health may be impacted by cold homes.
What is covered?The scheme can provide substantial funding, including potential full payment of installation costs for eligible applicants, subject to assessment.
How to apply?Interested households should contact participating energy providers such as British Gas, EDF, E.ON, Octopus Energy, or Scottish Power to check eligibility and start an assessment.
Scheme duration:Runs from April 1, 2022, through March 31, 2026.

This program offers eligible households the chance to install solar energy with lowered or no upfront expenses.

Warm Homes Plan – Partial Funding Support for Lower-Income and Social Housing Tenants (2025–2028)

Set to operate between 2025 and 2028, the Warm Homes Plan offers partial funding primarily aimed at social housing tenants, renters, and low-income households.

Criteria for eligibility:Designed for social housing occupants, renters, and households earning under approximately £31,000 yearly.
Funding type:Partial financial assistance toward solar panel installation costs.
How to apply:Applicants should contact local councils or official government websites to verify eligibility and find application details.

This initiative aims to expand renewable energy access for renters and social housing residents.

Groups That Can Benefit from UK Solar Grants

Homeowners and landlords—may qualify for 0% VAT, SEG, and some income-based grants.
Low-income households—can access full or partial funding through ECO4 and the Warm Homes Plan.
Renters and social housing tenants—primarily benefit via the Warm Homes Plan and local schemes.
Businesses—may benefit from 0% VAT relief and participate in SEG if solar systems are installed.

Various schemes target a broad range of applicants, encouraging renewable energy uptake across the UK.

Planning Permission Considerations for Solar Installation

In the UK, solar panel installations usually count as permitted development, so planning permission is generally not required. However, exceptions include:

Properties in designated conservation areas.
Listed buildings or homes with particular historical or architectural protections.

Owners in these categories should consult local planning authorities before installation.

Possible Savings from Solar Energy in 2025 with Grants

Energy bill reduction:Homeowners installing solar panels and battery storage may see savings depending on system size, energy consumption, and local electricity rates. Estimates suggest annual savings between roughly £670 and £1,020.
Income from surplus energy:Participating in the Smart Export Guarantee can provide additional financial returns of approximately £80 to £170 annually.

These figures are based on existing data and may vary according to individual circumstances and market conditions.
