2025 Government Solar Panel Grants UK Scheme

Unlock Free Solar Panel Grants and Energy Efficiency Measures in 2025

How Long Does It Take Solar Panels to Pay for Themselves UK?

Reducing your energy bills while increasing your home’s value has never been easier. Thanks to a range of free solar panel grants and energy efficiency measures supported by the UK government, homeowners now have access to incredible savings when installing solar panels, heat pumps, and other green technologies.

This guide explores every major scheme available, breaks down the cost of solar panels, and helps you navigate the opportunities available in 2025 and beyond.

What Are Solar Panel Costs in the UK With Government Grants?

Solar panels have become much more affordable in the UK — and even more so when taking advantage of government support. The average cost of solar panels can range from £5,000 to £8,000 for a typical 3-4kW domestic system. However, when combining government grants and schemes, your costs of installing can be reduced significantly, or even to zero.

Current available support includes:

  • ECO4 scheme: Offers free solar panels to eligible low-income households.

  • Solar Together: Save up to 25% through collective purchasing.

  • Home Upgrade Grant Phase 2 (HUG2): Grants up to £10,000 towards solar panels and other energy-saving measures.

  • Home Energy Scotland Grant: Up to £6,000 for Scottish residents.

  • Welsh Government Warm Homes Scheme: Access free solar panels through government support.

  • 0% VAT: Applies to the purchase and installation of solar energy systems.

Each scheme offers a unique route to reduce your energy bills and make a smart investment in your home’s future.

How to Verify Your Eligibility for ECO4 Government Scheme Solar Panels

The ECO4 scheme (Energy Company Obligation 4) is one of the biggest drivers behind free solar panel grants in the UK.

You may qualify if:

  • Your property has an EPC (Energy Performance Certificate) rating of D or lower.

  • Your household income is considered low.

  • You are receiving specific benefits, including:

  • Income-based Jobseekers Allowance (JSA)

  • Income-related Employment & Support Allowance (ESA)

  • Income Support (IS)

  • Universal Credit (UC)

  • Housing Benefit

  • Working Tax Credit (WTC)

  • Child Tax Credit (CTC)

  • Pension Credit Guarantee or Savings Credit

These criteria help the government target energy efficiency measures where they are most needed — helping disadvantaged communities reduce their energy burden.

If you think you qualify, visit our dedicated ECO4 page to apply today.

Getting 0% VAT for Solar Panels and Storage Batteries

Thanks to a change in government policy, installing solar panels and batteries now attracts 0% VAT.

Key points:

  • Applies to solar panels, heat pumps, and standalone batteries.

  • Available across England, Scotland, and Wales.

  • Valid until March 31, 2027.

This initiative not only reduces the cost of installing but also boosts adoption of sustainable technologies to lower national carbon emissions.

Whether you are installing panels immediately or planning upgrades, make sure your supplier reflects the 0% VAT on your invoice.

Solar Together: Save Up to 25% on Solar Panels

How Does Solar Together Work?

Solar Together operates like a group-buying programme managed by local authorities. By signing up with neighbours in your area, you unlock access to:

  • Lower costs thanks to bulk purchasing.

  • Trusted, vetted solar installers.

  • Tailored quotes based on your individual property and needs.

Why Choose Solar Together?

Unlike traditional shopping around, Solar Together flips the model: installers come to you, competing for your business.

Homeowners typically save up to 25% on the cost of solar panels versus arranging installation independently.

Home Upgrade Scheme (HUG2): Up to £10,000 for Solar Panels

Who Can Benefit From HUG2?

Running until March 2025, HUG2 offers substantial help for low-income households looking to upgrade their energy systems. Eligible improvements include:

  • Installing solar panels

  • Adding heat pumps

  • Loft, cavity, and floor insulation

  • High-performance windows and doors

HUG2 Eligibility Requirements:

  • Home must be off the gas grid and EPC-rated D or lower.

  • Household income under £31,000 per year (gross).

  • Or located in a deprived area according to the Index of Multiple Deprivation.

Landlords with four or fewer properties may also participate, though they must contribute a third of the project costs.

HUG2 is a critical pathway for homeowners seeking cleaner, more affordable energy solutions while protecting themselves from soaring energy bills.

Solar Panel Grants for Renters

Yes! Tenants in privately rented accommodation may access ECO4 or LA Flex schemes provided:

  • Their landlord gives permission for the works.

  • The home meets the EPC and income criteria.

What is LA Flex?

Local Authority Flexibility (LA Flex) extends ECO4 eligibility to more people based on:

  • Low household income

  • Risk of fuel poverty

  • Vulnerable occupants (elderly, disabled, families with young children)

Speak to your local authority about LA Flex pathways if you think you might qualify.

Heat Pumps: A Smart Addition to Solar Systems

Why Combine Solar Panels with Heat Pumps?

Installing a heat pump alongside your solar panel system can supercharge your home’s sustainability. Heat pumps:

  • Use renewable energy to heat your home.

  • Slash reliance on expensive gas boilers.

  • Further cut your energy bills when powered by solar energy.

Together, solar panels and heat pumps offer one of the most efficient, low-carbon ways to run a modern home.
