UK Government Grants for Solar Panels

by

Installing solar panels is one of the smartest ways UK homeowners can cut energy bills and reduce carbon footprints. But with rising installation costs, many wonder—is there any government help available?

This article breaks down the key UK government grants for solar panels, who qualifies, how to apply, and how much you could save.

Why the UK Government Supports Solar Energy

The UK government is pushing for net-zero emissions by 2050, and solar power plays a huge role in achieving that. Solar panels help reduce national dependence on fossil fuels and lower carbon output from homes and businesses.

To encourage more uptake, the government offers financial support—through grants, loans, and incentive schemes—to make going solar more accessible.

Are There Government Grants for Solar Panels in the UK?

Yes, there are UK government-backed grants and incentives for solar panels in 2025, though the available programs depend on your location, income level, and property type. While there isn’t a single universal grant for everyone, several funding options can reduce the upfront cost or provide long-term savings.

Top Solar Panel Grants and Schemes in 2025

Here’s a breakdown of the most current UK solar panel incentives:

1. ECO4 Scheme (Energy Company Obligation)

The ECO4 scheme helps low-income households install energy-efficient upgrades—including solar panels—at no cost.

  • Who qualifies?

    • Households receiving certain government benefits

    • Low-income homes (below £31,000 annual income)

    • Homes with poor energy efficiency ratings (E, F, or G)

  • What’s covered?

    • Full or partial funding for solar PV panels

    • Additional upgrades like insulation and heating systems

  • How to apply:

    • Through an approved installer or local council participating in ECO4

    • You’ll need to complete an eligibility assessment

ECO4 runs until March 2026, but funding is limited—early application is smart.

2. Home Upgrade Grant (HUG 2)

HUG 2 supports off-grid and low-income homes with energy upgrades, including solar installations.

  • Eligibility:

    • Off-gas-grid homes (not connected to the mains gas supply)

    • Income under £31,000 or eligible for benefits

    • EPC rating of D, E, F, or G

  • What’s included:

    • Solar PV systems

    • Heat pumps, insulation, and smart controls

  • Available until March 2025 (may be extended if successful)

  • How to apply:

    • Applications are made through your local authority or energy hub

This is particularly beneficial for rural households who rely on oil or electric heating.

3. Smart Export Guarantee (SEG)

While not a grant, SEG lets you earn money by selling unused solar electricity back to the grid.

  • How it works:

    • You get paid for excess electricity you export

    • Rates vary by supplier—currently ranging from 1p to 15p per kWh

  • Requirements:

    • Your solar system must be installed by a certified installer (MCS-accredited)

    • Must have a smart meter capable of tracking exported energy

  • Top suppliers offering SEG include:

    • Octopus Energy

    • E.ON Next

    • British Gas

Over time, SEG can significantly lower your net energy costs.

4. 0% VAT on Solar Panels

As of 2022, the UK government removed VAT on solar panel installations. This continues in 2025.

  • What it means:

    • You pay 0% VAT instead of the standard 20%

    • Applies to solar PV systems and battery storage

  • Eligibility:

    • Applies to domestic installations only

    • You must use a VAT-registered installer

This tax break alone can save homeowners up to £1,000 or more on installation.

5. Local Authority and Regional Grants

Many local councils offer their own solar funding initiatives.

  • Examples:

    • Greater London Authority offers Solar Together—a group-buying scheme for cheaper installations

    • Some councils provide top-up grants under ECO4 or HUG

    • Energy hubs may offer loans or subsidies in regions like the West Midlands, Greater Manchester, and the South West

  • Where to check:

    • Your local council’s website

    • Local energy hubs or partnerships

Can You Get Free Solar Panels in the UK?

Yes, under certain schemes like ECO4 or HUG 2, you may be eligible for completely free solar panels.

These programs target:

  • Low-income families

  • Homes with low EPC ratings

  • Residents on benefits (Universal Credit, Pension Credit, etc.)

However, these are means-tested—not every household qualifies. The best way to find out is to complete an eligibility check through an approved energy supplier or local authority.

How Much Do Solar Panels Cost Without a Grant?

Here’s a rough breakdown of solar panel installation costs in 2025:

System Size Number of Panels Estimated Cost Typical Output (kWh/year)
2 kW 5–6 £3,500–£4,000 1,700–2,000
3 kW 7–8 £4,500–£5,000 2,500–3,000
4 kW 10–12 £5,500–£6,500 3,500–4,200
5 kW 12–14 £6,500–£8,000 4,500–5,500

Grants can reduce these figures significantly, especially for qualifying households.

What About Solar Panel Grants for Pensioners?

Yes, pensioners may qualify for solar panel grants under ECO4 or HUG 2, especially if receiving benefits.

Relevant benefits include:

  • Pension Credit

  • Attendance Allowance

  • Housing Benefit (in some cases)

Additionally, many councils prioritize elderly homeowners or tenants when allocating energy funding. If you’re over 60 and on a fixed income, it’s worth exploring these options.

How to Apply for UK Solar Panel Grants

Follow these steps to start your application process:

  1. Check Eligibility

    • Use GOV.UK or energy supplier websites

    • Review income thresholds and benefit requirements

  2. Contact Approved Installers

    • Look for MCS-certified installers (essential for SEG and most grants)

  3. Apply Through Your Council or Installer

    • Some schemes are accessed through your local council

    • Others go directly through approved contractors

  4. Get a Home Energy Assessment

    • Required to confirm EPC rating and qualify for many grants

  5. Compare Offers and Sign Agreement

    • Get multiple quotes to ensure you’re getting value

    • Understand all terms, especially if the panels are installed under a “rent-a-roof” model

Common Myths About UK Solar Panel Grants

Let’s clear up some confusion:

  • Myth 1: Solar panels are always free
    Not true. Most homeowners still contribute some amount unless they qualify under specific low-income schemes.

  • Myth 2: Solar power doesn’t work in the UK
    Solar panels work even on cloudy days and can cover 60–80% of an average household’s annual electricity needs.

  • Myth 3: You can only get help once
    You can access different types of funding (e.g., ECO4 + SEG + 0% VAT) as long as you meet the criteria.

Conclusion: Should You Apply for a Solar Panel Grant in 2025?

If you’re thinking of installing solar panels, now’s the time to act. With a mix of national and local grants, SEG payments, and VAT relief, homeowners can cut thousands off installation costs—and save on energy bills for decades.

Whether you’re a pensioner, on a tight budget, or just environmentally conscious, there’s likely a scheme out there to support you.

Don’t wait. Check your eligibility today and start your journey toward cheaper, cleaner energy. You could be one call or click away from major savings
