Rising electricity prices and growing environmental awareness mean more homeowners across the South East and East Anglia are turning to solar energy. While the long term savings are clear, the upfront investment can still feel like a hurdle.
The good news is that in 2026, there are more flexible ways than ever to fund a solar installation. Whether you’re looking to pay outright, spread the cost or reduce pricing through collective schemes, there’s an option to suit most households.
At SolarTherm UK, we help homeowners navigate these choices every day – ensuring systems are not only technically sound, but financially sensible too.
Your Main Options for Paying for Solar Panels
Most UK homeowners choose one of three routes:
- Paying upfront using savings
- Spreading the cost with finance or loans
- Grants and government backed schemes
Each approach has its own advantages and disadvantages depending on your budget and long term plans.
Paying Upfront: The Most Cost Effective Option
If you have access to savings, paying in full typically delivers the strongest return on investment. There is no interest or borrowing costs, you own the system immediately and you maximise long term savings on electricity.
What to consider:
- Choose an MCS accredited installer to ensure eligibility for SEG payments
- Look closely at warranties and workmanship guarantees
- Consider adding battery storage at installation to maximise self-consumption
SolarTherm UK insight:
Many of our customers in Essex, Kent and Suffolk choose this route to maximise long term ROI, particularly when pairing solar with battery storage.
Financing Solar Panels: Spreading the Cost
If paying upfront isn’t ideal, financing allows you to install solar with manageable monthly payments. Many UK lenders now offer Green Loans, specifically for energy efficient upgrades. Some will include introductory low or 0% interest periods with terms typically ranging from 3-10 years. Monthly payments will vary depending on system size and brand, but most payments can be offset against monthly savings.
Green Mortgages work similarly to Green Loans, in so much that they are specifically for energy efficient upgrades. They are usually tied to remortgaging or refinancing but often come with lower interest rates than personal loans.
Many installers now offer in house or partnered finance. This is usually a simple application process that is carried out during your feasibility study alongside your contract. In house finance usually includes a low deposit then monthly payments across a set period, where your payments can be offset against your savings.
Important: always verify lenders through the Financial Conduct Authority (FCA) and seek independent financial advice where needed. Check the total repayment cost (APR), not just the monthly payments and ensure you know about any early repayment fees and the long term suitability for your budget.
Alternative Ways to Fund Solar
Deposit and Payment Plan – many homeowners choose to pay a small upfront deposit (typically 10-20%) and spread the remaining cost.
Buy Now, Pay Later – deferred payment schemes allow installation now, with payments starting at a later date. These are useful when you’re expecting a financial boost but want immediate energy savings. Always be aware of when interest starts and any hidden fees or penalties.
Remortgaging – releasing equity can fund solar upfront. While these benefit you as they have a lower interest rate than personal loans, they do extend your mortgage term and increases the total repayment over time.
Grants and Government Backed Funding Schemes
As of 2026, there is currently no active nationwide grant scheme specifically for solar panel installations. The previous ECO4 (Energy Company Obligation) scheme closed in March 2026, leaving a temporary gap in direct funding for most homeowners.
However, the UK government has committed £15 billion in future funding aimed at improving energy efficiency across millions of homes. While full details and timelines are still being finalised, this investment is expected to support:
- Grants for low-income and vulnerable households
- Subsidised or low-interest loans for home energy upgrades
- Expanded funding for schemes like the Boiler Upgrade Scheme (focused on heat pumps)
At present, there is no confirmed launch date for these new programmes.
Local Authority Backed Schemes (Group Buying Schemes)
Group buying initiatives allow homeowners to access discounted solar installations by pooling demand. While they can be popular as they drive prices down, they are usually off the shelf packages that aren’t designed for the property and usually not optimised for maximum results. At SolarTherm UK, we have also been involved in resolving issues with group buying installations due to limited ongoing support.
