What This Covers
Green energy and EV finance covers two overlapping areas: financing electric vehicles for business use, and financing on-site renewable energy and efficiency installations. Both sit within asset finance. Both attract specific tax incentives. Both carry residual value and technology risks that conventional asset categories do not.
The market has matured quickly over the last three years. Specialist lenders, manufacturer finance arms, and government-backed schemes now cover EV fleets and renewable assets with confidence. The two categories share a label, but the product structures and lender risk profiles diverge sharply once you look past the headlines. We rate the tax case as the thing that genuinely changes the maths here.
Electric Vehicle Finance for Businesses
Business EV finance follows the same structural options as conventional vehicle finance: hire purchase, finance lease, contract hire, and operating lease. The differences sit in the tax incentives, the residual value dynamics, and the charging infrastructure that almost always rides alongside fleet electrification.
Hire purchase looks particularly strong for EVs because of the enhanced capital allowances. Zero-emission cars attract a 100 percent first-year allowance, so the full purchase price comes off taxable profits in year one. When your fleet manager weighs HP against contract hire on a zero-emission car, that allowance usually tips the decision toward HP for any profitable trading entity. It pushes the tax case past where it sits for petrol and diesel.
Contract hire is still the most common fleet product for EVs. Payments are fixed, residual value risk sits with the lender, and the vehicle goes back at term end. The catch is that rates have run higher than expected. Second-hand EV values are unsettled, so fleet funders have set conservative guaranteed future values to protect themselves. You pay for that caution in the monthly rate.
EV Charging Infrastructure Finance
Charging infrastructure is the necessary partner to fleet electrification, and it is financeable in its own right. Workplace charging points, depot systems, and rapid chargers can be funded through specialist EV infrastructure lenders. If you electrify a depot, you can usually fund the vehicles and the chargers in one combined facility, and we rate that as the tidier route when both land at once.
The OZEV Workplace Charging Scheme provides grants of up to £350 per socket, capped at 40 sockets per applicant as of June 2026. Grant funding cuts the capital that needs financing. Lenders will generally fund the post-grant residual cost, and some will advance against the full cost before the grant lands.
Infrastructure has a long useful life, with commercial charging kit typically lasting 10 to 15 years, which suits longer-term HP or finance lease structures. Operating lease is rare here. The asset is bolted to a specific site, and recovery becomes awkward for the lender if you vacate the premises mid-term. That site-tie is the whole reason.
Solar and Renewable Energy Finance
On-site renewables, meaning solar PV, battery storage, and wind turbines on suitable sites, are financed as capital assets. Solar PV for commercial premises typically runs £30,000 to £300,000 depending on scale. Battery storage adds £10,000 to £50,000 or more per installation, sometimes considerably more on larger sites.
Hire purchase dominates solar and battery deals. The asset lasts 20 to 25 years, generates a revenue or cost-saving stream that effectively pays the instalments, and qualifies for capital allowances. The exact allowance position depends on whether the install falls under the annual investment allowance or the enhanced allowances reserved for specific energy-saving technologies. We rate HP as the natural fit when the asset pays for itself.
Power purchase agreements (PPAs) sit outside asset finance but are a real alternative to ownership. The installer keeps the system and you buy the electricity it generates at a rate below grid cost. PPAs suit you if you want the energy saving without the capital commitment, and you accept giving up the underlying asset value. That is the trade-off in one line.
Tax Incentives and Their Impact
The tax case for green and EV investment is materially better than for conventional assets. Zero-emission vehicles attract 100 percent first-year capital allowances. Energy-efficient plant and machinery can qualify for enhanced capital allowances. Solar PV and battery installations may qualify too, depending on configuration and the accounting standard applied.
First-year allowances are front-loaded, so the deduction lands in year one rather than being spread across the asset’s life. When a director models a purchase a fortnight either side of the year end, the deduction can shift by a full accounting period. We would model that timing with an accountant before the finance structure is signed off, because it is worth real money.
Residual Value and Technology Risk
EV and green energy assets carry technology risk that conventional assets do not. Battery technology keeps improving, which drags on the residual value of current-generation EVs and storage systems. Solar panel efficiency gains erode the relative value of older installations. Lenders price this in, which is why EV contract hire rates have not simply tracked their petrol equivalents.
For HP agreements where you keep the asset, technology risk lands on the business, not the lender. A solar panel bought today will still generate electricity in fifteen years, but its second-hand market value may be modest. For most operators the ongoing energy saving justifies the spend regardless, though it matters if refinancing or sale is part of your longer-term plan. We would treat technology risk as the real variable for anyone who expects to sell the asset on.
Grant Schemes and Government Support
Several government schemes support green and EV investment. The OZEV Workplace Charging Scheme covers EV charging, as above. The Industrial Energy Transformation Fund (IETF) backs efficiency projects in energy-intensive industries. Local authority and combined authority grants exist in some regions. Schemes shift often, so check current availability via the Business Energy Efficiency Programme and OZEV directly.
Grant funding usually has to be applied for and confirmed before the asset is bought, not after. When the finance team arranges funding alongside a grant, it has to reflect the net cost, and lenders need to know about any conditions affecting ownership, use, or disposal during the term. Miss this sequencing and the grant can be clawed back. Get the order wrong and it costs you the grant.
How We Checked This
Green energy and EV finance structures reflect current UK market practice as of June 2026. OZEV Workplace Charging Scheme grant levels and eligibility verified against current scheme documentation. Capital allowance treatment is consistent with HMRC guidance at June 2026. Solar installation cost ranges reflect current UK market figures. We did not arrange or test any of these facilities ourselves.
Specific rates, grant availability, and tax treatment depend on individual business circumstances; verify with a specialist lender and accountant before committing. Treat the numbers here as orientation, not a quote.
