UK Solar Grants 2025 to Reduce Energy Bills in the United Kingdom

UK solar grants and support schemes in 2025 may help reduce your energy bills and offer partial or full funding for eligible households. Discover practical ways to explore these opportunities and start saving on energy costs through a variety of financial incentives and programs.

Financial Support Available for Solar Panel Installation in 2025

0% VAT on Solar Panels and Batteries Until March 2027

A significant saving available to UK residents and businesses is the temporary 0% VAT rate on solar panels, battery storage systems, and certain energy-saving equipment. Introduced by the UK government to encourage renewable energy adoption, this VAT exemption has been in effect since April 1, 2022, and is set to continue until March 31, 2027.

**Who qualifies?**All UK homeowners and businesses purchasing and installing solar panels or battery storage systems.
**Potential savings:**This exemption can reduce the cost by approximately the VAT amount, which can be up to around £2,850 on a standard 4kW solar installation including batteries, depending on the system price.
**How to claim?**There is no separate application process; certified solar installers typically apply this VAT rate during installation.

This VAT exemption helps lower initial investment costs for solar energy equipment and supports wider adoption across the UK.

Smart Export Guarantee (SEG) – Earn for Surplus Solar Energy

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

**Eligibility:**UK property owners with solar panels, compatible battery storage, and a smart meter.
**Potential payments:**Returns depend on the energy company and tariff selected and may range approximately between £80 and £170 annually.
**How to participate:**Homeowners can compare SEG tariffs from different energy providers and register with the one offering the preferred rate to receive payments for exported energy.

Through SEG, solar panel owners can potentially offset energy costs by generating additional income or credits.

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

The Energy Company Obligation 4 (ECO4) scheme aims to assist low-income households with financing solar energy installations.

**Who is eligible?**Households with qualifying income levels (annual incomes under approximately £31,000) or residents whose health may be affected by cold homes.
**What is covered?**The scheme can provide significant funding, including potential full coverage of installation costs for qualifying 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 determine eligibility and initiate an assessment.
**Scheme timeline:**Active from April 1, 2022, through March 31, 2026.

This scheme offers an opportunity for eligible households to access solar energy with reduced or no upfront costs.

Scheduled to run between 2025 and 2028, the Warm Homes Plan provides partial funding support aimed at social housing tenants, renters, and low-income families.

**Eligibility criteria:**Intended for social housing residents, renters, and households earning below approximately £31,000 annually.
**Funding type:**Partial financial assistance toward the costs of solar panel installation.
**How to apply:**Prospective applicants should consult local councils or official government websites for eligibility checks and application instructions.

This plan is designed to broaden access to renewable energy solutions for renters and social housing residents.

Groups That May Benefit from UK Solar Grants

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

Multiple schemes aim to cover a diverse range of applicants, promoting the adoption of renewable energy across the UK.

Planning Permission Considerations for Solar Installation

In the UK, solar panel installations typically qualify as permitted development, so planning permission is generally not required. However, exceptions apply, including:

Properties located in designated conservation areas.
Listed buildings or properties with specific historical or architectural protections.

Property owners in these categories are advised to consult local planning authorities prior to installation.

Potential Savings from Solar Energy in 2025 with Grants

**Reduction in energy bills:**Homeowners installing solar panels and battery storage might experience savings that vary based on system size, energy usage, and local electricity tariffs. Estimates suggest possible annual savings of approximately £670 to £1,020.
**Income from surplus energy:**Participation in the Smart Export Guarantee may provide additional financial returns of roughly £80 to £170 annually.

These figures are based on available data and can vary by individual circumstances and market conditions.

Applying for UK Solar Grants in 2025

0% VAT: No separate application is required; ensure that your installer is certified to apply this exemption.
