Can you finance battery storage?
Yes, and battery storage is one of the easier renewable assets to fund. Unlike a roof array, a battery system is usually a self-contained cabinet or container that can be disconnected and moved, so it retains recovery value and funders are more comfortable lending against it. Serial numbers on the battery modules and inverters make it identifiable, which matters. The main questions are the manufacturer’s standing, the warranty position, and whether the system is genuinely stand-alone or so deeply integrated into a building that it has become a fixture.
Used kit: Yes, cautiously. Used battery systems can be funded where module health data and remaining warranty are available, though degraded second-life units are generally declined.

What would battery storage cost per month?
Business asset finance is quoted on a flat rate, so that is what this shows — with the equivalent APR underneath, because the two are not the same number. A quick guide only; your actual rate depends on the asset, term, deposit and lender.
Representative example: on Hire Purchase, borrowing £25,000 over 48 months at a 6.0% flat rate (equivalent to 11.5% APR representative), you would repay around £646 a month; total amount repayable approximately £31,000, of which £6,000 is the cost of finance. This calculator is for illustration only — it is not a quote or an offer of finance, and the rate and repayments you are offered will depend on the asset, term, deposit and your circumstances. CW Asset Finance is a credit broker, not a lender, and may receive a commission from the lender that funds your agreement. All finance is subject to status, affordability and lender approval.

How lenders treat it
Batteries are the strongest recovery proposition in the renewables family. A containerised or skid-mounted system sits on a base rather than forming part of the structure, so a funder can in principle uplift and resell it — and that changes the underwriting tone completely compared with a rooftop array. Expect scrutiny of the battery chemistry and the manufacturer’s covenant, because a warranty from a supplier that disappears is worth little, and degradation over the agreement matters to residual thinking. Where the system earns from flexibility services or avoided peak charges, some funders will look at that contracted income alongside the accounts. Systems hard-wired into a building’s fabric drift back towards fixture treatment and lose that advantage.

Who buys one
Sites already running solar that are exporting more than they use, manufacturers exposed to peak-rate consumption, cold storage and data-adjacent operations that cannot tolerate dips, and farms balancing generation against irrigation or milking loads. The trigger is often a half-hourly bill showing expensive peak draw, or a grid connection that cannot be upgraded quickly enough to support new machinery or charging.

How it is treated for tax
Bought on hire purchase, business plant and machinery normally qualifies for capital allowances on the full cost even though you pay for it monthly, which is a large part of why hire purchase is the common structure. On a finance lease you generally set the rentals against profit instead. The rules change between budgets and your position depends on how you trade, so treat this as the direction of travel and get your accountant to confirm the detail before you commit.
Battery storage finance questions
Is battery storage easier to finance than solar panels?
Usually, yes. A battery cabinet or container can be disconnected and removed, so it holds recovery value in a way a bolted-down roof array does not. That gives funders more comfort and tends to widen the choice of who will look at the deal, particularly for tenants who do not own their premises.
Does the battery have to be bought with solar?
No. Plenty of businesses install storage on its own to shift consumption away from expensive peak periods or to support a constrained grid connection. Funders assess it as a piece of electrical plant in its own right, and a stand-alone battery application does not need a PV array attached to it.
What happens to the agreement as the battery degrades?
Degradation is the funder’s problem to price, not something that changes what you pay once an agreement is signed. It does affect appetite, which is why manufacturer warranties and cycle guarantees get read carefully at the application stage, and why well-known chemistries attract more competitive treatment than obscure ones.
Can revenue from flexibility services support the application?
Sometimes. If you hold a contract with an aggregator or supplier for grid services, certain funders will take that into account as part of affordability. Contracted revenue carries more weight than projected revenue, so send us the agreement rather than the modelling spreadsheet if you have one.
Do I need to own the building for battery finance?
It helps but it is far less critical than with rooftop solar. Because the system is removable, tenants have realistic options, although the funder will still want to know where the unit sits and may ask the landlord to acknowledge that the battery is not part of the premises.
