by

Thinking about installing solar panels in Wales? You’re in the right place. As energy prices remain high and more people look for greener energy solutions, solar panels have become an increasingly smart investment. But let’s be honest—the upfront cost can be a big barrier.

This guide breaks down all the grants, loans, and support schemes for solar panels in Wales in 2025, who qualifies, and how to apply—so you can make an informed (and cost-effective) decision.

Are There Grants for Solar Panels in Wales?

Yes, there are grants and financial incentives for solar panels in Wales, offered through both UK-wide and Welsh Government-backed schemes. While there isn’t one universal grant for everyone, there are multiple programs that can reduce or eliminate the cost of solar panel installation—especially for low-income households.

What Solar Panel Grants and Incentives Are Available in Wales?

Here’s a detailed look at the current solar support options available in 2025:

1. Nest Scheme (Welsh Government)

The Nest scheme offers free energy efficiency improvements, including solar panels, to eligible households in Wales.

  • Who qualifies?

    • Homeowners or private tenants

    • Households receiving certain benefits (e.g., Universal Credit, Pension Credit, ESA)

    • People with chronic health conditions

    • Low-income households with high energy bills

  • What’s covered?

    • Solar PV panels (subject to property suitability)

    • Insulation, central heating systems, draught proofing

  • Application process:

    • Apply directly through the Welsh Government’s Nest website

    • Free home energy assessment provided

If eligible, you could receive solar panels and other upgrades completely free under the Nest scheme.

2. ECO4 Scheme (UK-wide, available in Wales)

The Energy Company Obligation (ECO4) scheme supports low-income households in Wales with energy efficiency upgrades, including solar PV systems.

  • Who can apply?

    • Households receiving certain means-tested benefits

    • Annual income under £31,000 (even without benefits)

    • Homes with EPC ratings of D to G

  • What’s included?

    • Full or partial funding for solar panels

    • Potential combination with insulation and new boilers

  • How to apply:

    • Through an ECO-accredited installer or via your local council

ECO4 is a key route to get free or subsidised solar panels in Wales, particularly for vulnerable groups.

3. Smart Export Guarantee (SEG)

The Smart Export Guarantee is a UK-wide scheme that lets you earn money from your solar panels by selling surplus electricity back to the grid.

  • How it works:

    • Energy suppliers pay you for every kWh of excess electricity you export

    • Rates vary by supplier—typically between 1p and 15p per kWh

  • Eligibility:

    • Your system must be installed by an MCS-certified installer

    • You’ll need a smart meter capable of tracking exported energy

While SEG isn’t a grant, it provides steady income over the lifespan of your solar system, improving return on investment.

4. 0% VAT on Solar Installations

As of 2022 and continuing through 2025, VAT on solar panels and battery storage systems is 0% in Wales and the rest of the UK.

  • What it means:

    • You don’t pay the usual 20% VAT on installation costs

    • Applies to domestic properties only

  • Savings:

    • This can knock hundreds or even thousands of pounds off the total cost

It’s a valuable nationwide incentive that boosts affordability across Wales.

5. Local Authority and Regional Schemes in Wales

Many local authorities in Wales offer targeted energy support programs, sometimes funded through UK Shared Prosperity Funds or local partnerships.

Examples include:

  • Group-buying schemes or pilot projects

  • Top-up grants for energy upgrades

  • Incentives for rural or fuel-poor households

To find out what’s available:

  • Visit your local council’s website

  • Contact the Nest helpline or local energy advice services

Can You Get Free Solar Panels in Wales?

Yes, you can get free solar panels in Wales if you meet specific eligibility requirements under schemes like Nest or ECO4.

These schemes prioritize:

  • Households on low incomes or receiving benefits

  • People with health conditions impacted by cold homes

  • Properties with poor EPC ratings (D, E, F, or G)

For everyone else, grants and incentives will reduce but not eliminate costs. Still, with 0% VAT and SEG income, the long-term savings are real.

How Much Do Solar Panels Cost in Wales?

If you don’t qualify for full funding, here’s what you can expect to pay:

System Size Number of Panels Estimated Cost Average Savings/Year
2 kW 5–6 £3,500–£4,000 £250–£300
3 kW 7–8 £4,500–£5,200 £350–£400
4 kW 10–12 £5,500–£6,500 £500–£600
5 kW 12–14 £6,800–£8,200 £600–£750

SEG payments and electricity savings combined mean a typical solar setup pays for itself within 6–9 years.

Are There Solar Panel Grants for Pensioners in Wales?

Yes, pensioners in Wales are often eligible for solar grants under the Nest scheme or ECO4, especially if they receive:

  • Pension Credit

  • Attendance Allowance

  • Winter Fuel Payment

  • Housing Benefit

Many local programs also give priority to older residents, especially those with long-term health issues or fixed incomes.

Pensioners may also benefit from home energy assessments, free insulation, and heating system upgrades alongside solar.
