Introduction: Save Big With UK Solar Grants in 2025
Switching to solar energy has never been more rewarding in the UK. With energy prices still high in 2025, the government continues to support households through solar panel grants and green energy incentives.
If you’re wondering how to reduce installation costs or even get solar panels partly funded, this guide will walk you through the top UK solar grants, who qualifies, and how to apply step by step.
Why the UK Government Offers Solar Grants
The UK government aims to reach net zero emissions by 2050, and promoting renewable energy is a big part of that mission.
By helping homeowners and landlords install solar panels, the government:
- Lowers carbon emissions
- Reduces dependency on fossil fuels
- Helps families save on electricity bills
- Supports long-term clean energy growth
That’s why several solar incentives and rebate schemes are still active in 2025 — some even offering free solar installations for qualifying households.
Top UK Solar Grants & Incentives in 2025
Here are the most popular UK solar panel grants and funding programs available this year:
1. ECO4 Scheme (Energy Company Obligation)
The ECO4 Scheme is one of the biggest UK government initiatives for home energy efficiency.
What It Covers:
- Free or discounted solar panel installation
- Home insulation and heating upgrades
Who Qualifies:
You may be eligible if you:
- Receive government benefits (like Universal Credit or Pension Credit)
- Have a low household income
- Live in an energy-inefficient home (EPC rating D–G)
How to Apply:
- Contact an approved ECO4 installer.
- They’ll assess your home’s eligibility.
- If you qualify, they’ll arrange installation — often at no cost to you.
💡 Tip: Many energy suppliers (like British Gas, EDF, and E.ON) offer ECO4-funded projects.
2. Smart Export Guarantee (SEG)
Even if you pay for your panels, the Smart Export Guarantee lets you earn money for the solar power you export back to the National Grid.
How It Works:
- You’re paid for every kilowatt-hour (kWh) your system exports.
- Rates vary by energy supplier (typically 4–15p per kWh).
- Payments are monthly or quarterly, directly into your bank account.
Who Qualifies:
- Homeowners with grid-connected solar panels (up to 5MW capacity).
- Systems must be installed by an MCS-certified installer.
Example:
If your solar panels generate 3,000 kWh per year and you export half, you could earn £60–£200 annually depending on your supplier’s rate.
3. Home Upgrade Grant (HUG2)
The Home Upgrade Grant (Phase 2) is aimed at improving energy efficiency in off-gas homes across England.
What’s Covered:
- Solar panel installation
- Loft, wall, and floor insulation
- Low-carbon heating solutions
Eligibility:
You may qualify if:
- Your property is off the gas grid.
- You have a household income below £31,000.
- Your home has a low energy efficiency rating.
💡 Important: The grant is fully funded, meaning you don’t pay anything if approved.
4. Boiler Upgrade Scheme (BUS)
While this grant mainly supports heat pumps, it’s worth mentioning if you’re upgrading to an eco-friendly home setup.
You can combine solar panels with a heat pump to maximize efficiency — and the BUS provides up to £7,500 off installation costs.
Eligibility Criteria:
- Must own the property (home or small business).
- Replace an existing fossil fuel heating system.
- Use an MCS-certified installer.
5. VAT Relief on Solar Installations (Zero VAT)
As of 2025, solar panels, batteries, and heat pumps are still zero-rated for VAT.
That means no 20% tax on the cost of your installation — saving you hundreds to thousands of pounds instantly.
Who Benefits:
Everyone! Homeowners, landlords, and even small businesses can enjoy 0% VAT when they install solar systems in the UK.
Bonus: Local Council & Regional Grants
Some councils and devolved governments (like Scotland, Wales, and Northern Ireland) offer extra solar incentives.
Examples include:
- Home Energy Scotland Grants & Loans – up to £6,000 for solar and batteries.
- Nest Scheme (Wales) – free home energy improvements for low-income households.
- NI Sustainable Energy Programme – small grants for renewable upgrades.
Check your local council’s website for the latest programs in 2025.
How to Apply for UK Solar Grants (Step-by-Step)
Follow these steps to maximize your chance of approval:
- Check your eligibility — based on income, benefits, and property type.
- Get an EPC rating check — lower ratings (D–G) often qualify for free upgrades.
- Find an MCS-certified solar installer — required for ECO4 and SEG.
- Gather documents — proof of income, address, and property ownership.
- Apply online or through your local council — most programs take only a few weeks to approve.
- Schedule installation once approved — often fully or partially funded.
💡 Tip: Always work with trusted, certified installers to avoid scams or disqualification from incentives.
Who Can Benefit Most From Solar Grants in 2025
You’re most likely to qualify if you:
- Have a low to middle income.
- Receive government benefits.
- Live in a rural or off-grid area.
- Own or rent an older, less efficient home.
However, even higher-income households can still benefit from incentives like SEG payments and zero VAT.
How Much Can You Save With UK Solar Incentives?
Here’s a quick breakdown of potential savings in 2025:
| Incentive Type | Average Savings |
|---|---|
| ECO4 Solar Grant | Up to £5,000–£8,000 (fully funded) |
