Solar Panel Grants and Funding for UK Homes
Financial Support for Solar Panels in the UK: What Help Can Homeowners Get?
Installing solar panels has never been more affordable. While the upfront cost can still seem significant, many UK homeowners are surprised to discover that banks, building societies and government schemes now offer a range of financial incentives to make switching to solar easier.
Whether you’re planning a new solar PV system, battery storage or an electric vehicle charger, there are several ways to reduce the cost and improve your return on investment.
Why are banks supporting solar installations?
Banks and mortgage lenders are increasingly offering incentives for homeowners to improve the energy efficiency of their properties. Solar panels can reduce household energy bills, increase EPC ratings and potentially add value to a home, making them an attractive investment for both homeowners and lenders.
Many lenders now provide cashback, interest-free borrowing or discounted loans specifically for renewable energy improvements.
Nationwide Building Society
Nationwide offers one of the most attractive schemes currently available. Eligible mortgage customers can apply for Green Additional Borrowing, allowing them to borrow up to £20,000 at 0% interest for approved energy efficiency improvements, including:
- Solar panels
- Home battery storage
- Heat pumps
- Insulation
- Double glazing
For many households this removes one of the biggest barriers to installing solar by allowing the cost to be spread over time without paying interest.
Barclays Greener Home Reward
Barclays offers a Greener Home Reward, providing qualifying mortgage customers with cashback towards the installation of energy-saving improvements. The amount offered has been fluctuating recently, so if you are a Barclays customer, check with them on the latest amount they are contributing.
Solar panels and battery storage are among the eligible improvements, helping homeowners reduce the overall installation cost.
Halifax Green Living Reward
Halifax has introduced one of the UK’s most generous cashback schemes. Eligible mortgage customers can receive £1,000 cashback when installing rooftop solar panels or battery storage systems through approved installers. For many installations, this can cover a significant proportion of the scaffolding or installation costs.
Lloyds Bank
Lloyds also offers Green Living incentives for qualifying mortgage customers. Depending on the improvement being carried out, homeowners may be eligible for cashback towards renewable energy installations, including solar PV systems and battery storage.
Virgin Money
Virgin Money provides green mortgage incentives that reward customers making energy-efficient home improvements. Solar panels, batteries and other qualifying upgrades may be eligible depending on the current offer available.
Santander
Santander periodically launches green mortgage promotions offering cashback or preferential borrowing for homeowners improving the energy performance of their property. These schemes change regularly, but this is definitely worth checking if you bank with Santander.
Green Home Improvement Loans
Several lenders now offer unsecured loans specifically designed for environmentally friendly home improvements.
These loans can typically be used for:
- Solar panels
- Battery storage
- Electric vehicle chargers
- Heat pumps
- Insulation
- Windows and doors
Green loans often feature lower interest rates than standard personal loans.
Government Support
While the UK no longer offers a nationwide grant that pays directly towards the cost of solar panels for most homeowners, there are still several valuable forms of support.
Smart Export Guarantee (SEG)
Once your solar panels are installed, you can earn money by exporting unused electricity back to the National Grid. Energy suppliers participating in the Smart Export Guarantee (SEG) pay homeowners for every unit of surplus electricity they export. The amount you receive depends on your chosen energy supplier, with some tariffs paying significantly more than others.
Zero VAT on Solar Panels
The UK Government currently applies 0% VAT on the installation of:
- Solar panels
- Battery storage (when installed as part of an eligible project)
- Certain other energy-saving materials
This immediately reduces the cost of installation compared with previous years.
Warm Homes Plan
The Government is also introducing the Warm Homes Plan, which is expected to provide low-interest or interest-free finance for eligible energy efficiency improvements, including renewable technologies.
Details continue to evolve, but it is expected to help more homeowners spread the cost of installing solar.
ECO4 and Local Authority Grants
Households on lower incomes or receiving certain benefits may qualify for assistance through:
- ECO4 grants
- Local authority energy efficiency grants
- Regional retrofit schemes
Eligibility varies depending on household income, benefits and property type. The ECO4 grants are only for a limited time as they are due to come to an end in early 2027.
Don’t Forget Battery Storage
Many financial support schemes now include battery storage alongside solar panels.
Adding a battery allows homeowners to:
- Store excess daytime generation
- Use more of their own electricity and often go completely off-grid
- Charge overnight on cheaper electricity tariffs
- Power the home during peak-rate periods
For households with electric vehicles, combining solar panels, battery storage and a smart EV charger can dramatically reduce charging costs, meaning you can run your home and your vehicle for pennies.
Can Solar Pay for Itself?
If you plan to be in your current home for the next 5 years, the answer is usually yes.
Savings come from several sources:
- Lower electricity bills
- Payments through the Smart Export Guarantee
- Reduced EV charging costs
- Protection against future energy price rises
- Potential increase in property value
When grants, cashback and preferential finance are taken into account, the speed of the solar payback becomes even quicker, making the savings and overall return on investment even more attractive.
