Battery Storage Finance — Fund Every Install from Day One
Battery storage is one of the fastest-growing segments in the green tech market — but the upfront cost still stops deals in their tracks. Rubix Finance gives UK battery storage installers an FCA-compliant finance platform to turn hesitation into a signed contract.
Battery Storage Deals Stalling at the Payment Stage
A home battery storage system typically costs £4,000–£12,000 depending on capacity and brand. Customers understand the long-term value, but the upfront cost — especially when it's an add-on to solar — can derail an otherwise ready-to-sign deal.
Customers want battery storage but can't fund it alongside an existing solar quote
Retrofit battery sales are harder to close without a payment plan option
Competitors offering battery finance are winning installs that should be yours
No easy way to bundle solar and battery into a single affordable monthly payment
Specialist battery storage finance products are hard to access directly

Common Questions
Everything you need to know before getting started.
1Can customers finance a battery storage system as a standalone install, without solar?
Yes. Rubix Finance supports finance for standalone battery storage installations — customers do not need to be purchasing solar panels at the same time. We also support retrofit battery installs added to an existing solar array.
2Can solar and battery storage be bundled into one finance application?
Yes. If a customer is purchasing both a solar PV system and a battery storage system, the total project cost can be included in a single finance application, giving them one monthly payment to manage.
3What battery storage system sizes and brands can be financed?
Our platform supports finance for a wide range of battery brands and capacities — from single-phase home storage units through to larger commercial energy storage systems. The finance is based on project cost rather than a specific technology brand.
4What loan terms are available for battery storage finance?
Loan terms typically range from 24 to 120 months depending on the lender and the customer's profile. Shorter terms mean higher monthly payments; longer terms spread the cost for customers who need more flexibility.
5Does my business need FCA authorisation to offer battery storage finance?
Not necessarily. Rubix Finance is the FCA-authorised credit broker, and many installers work under our umbrella. Where your business model requires its own authorisation, we can guide you through a Limited Permissions FCA application.
6Is there any cost to join as a battery storage installer partner?
No. Joining the Rubix Finance network is completely free. We receive commission from lenders when applications are funded — there are no fees to you or your customers from Rubix Finance.
