Electric Vans: 100% First-Year Capital Allowance for Business Buyers 2026/27
How the 100% first-year capital allowance works for businesses buying electric vans in 2026/27, compared with petrol/diesel vans and how it interacts with the Annual Investment Allowance.
Why Electric Vans Get Favourable Capital Allowance Treatment
Businesses buying commercial vehicles have long been able to claim capital allowances โ tax relief for the cost of buying plant and machinery, spread over time or, more commonly for smaller purchases, claimed in full upfront via the Annual Investment Allowance (AIA). Electric and other zero-emission vans have additionally benefited from targeted 100% first-year allowances designed to encourage fleet electrification, which historically applied outside, or alongside, the ordinary AIA regime.
In practice, for most small and medium businesses buying one or a handful of vans a year, the AIA already delivers a full 100% deduction in year one for petrol, diesel or electric vans, because the AIA's generous annual limit comfortably covers typical van purchase costs. The electric-specific first-year allowance route matters most for larger businesses that have already used up their AIA limit on other equipment in the same accounting period, or in situations where the specific mechanics of first-year allowances versus AIA produce a marginally different result.

To claim the full 100% deduction in year one, a van generally needs to be:
- New and unused at the time of purchase (not a used or ex-demo vehicle, which follows different, less generous rules).
- Genuinely a van for tax purposes โ a vehicle primarily constructed for carrying goods rather than passengers.
- Bought outright by the business claiming the allowance, rather than leased (leased vehicles are dealt with differently โ see below).
Leasing Changes the Picture Entirely
A business that leases rather than buys its electric van doesn't claim capital allowances on the vehicle at all โ the leasing company, as the legal owner, claims those allowances instead. The business leasing the van simply deducts its lease rental payments as an ordinary revenue expense against profits, spread across the accounting periods the lease covers, rather than getting one large upfront deduction. This is a fundamentally different tax mechanism from outright purchase, and it's worth modelling both routes (buy with AIA/first-year allowance vs lease with ongoing rental deductions) before committing, since the cash flow and tax timing profile differ significantly.
Electric vs Diesel: Where the Real Difference Lies
Because AIA already gives most petrol and diesel van buyers a comparably generous year-one deduction, the tax-driven case for choosing electric over diesel for a van fleet increasingly rests on factors beyond the capital allowance itself:
- Vehicle Excise Duty โ electric vans have historically enjoyed favourable VED treatment relative to diesel, though EVs generally lost blanket VED exemption from April 2025.
- Fuel/running costs โ electricity typically costs meaningfully less per mile than diesel, especially with off-peak or depot charging.
- Clean Air Zone and ULEZ charges โ electric vans avoid daily emissions-based charges that diesel vans (especially older ones) may incur in city driving.
- Benefit-in-kind, where relevant โ if a van is available for meaningful private use, the van benefit charge (a flat annual figure) applies regardless of fuel type, though electric vans have sometimes attracted a nil or reduced rate in specific periods.
Buy outright (electric or diesel van, AIA or first-year allowance): full deduction in year one, reduces that year's corporation tax bill directly.
Lease: no upfront capital allowance for the business leasing it; rental payments deducted gradually as a revenue expense across the lease term.
The Balancing Charge Catch
It's worth understanding that claiming 100% of a van's cost upfront isn't a permanent tax saving in isolation โ it's primarily a timing benefit. If the van is later sold, the sale proceeds are generally brought back into the business's taxable profits as a balancing charge in the year of sale, which claws back some of the earlier relief. Over the full life of the asset, total tax relief broadly reflects the van's actual net cost (purchase price less resale value) โ the 100% first-year allowance simply brings that relief forward to when it's often most useful, in the year of purchase.
Frequently asked questions
Can a business deduct the full cost of a new electric van in year one?
Yes, in most cases, via a 100% first-year allowance (or the Annual Investment Allowance, which achieves the same full deduction), meaning the entire purchase cost of a qualifying new electric van can be deducted against taxable profits in the year it's bought, rather than spread over several years.
Does the 100% allowance apply to used or leased electric vans?
The 100% first-year allowance specifically targeting zero-emission vans is generally available only for new and unused vans. Leased vans don't qualify for capital allowances in the lessee's hands at all in the same way โ the leasing company claims allowances instead, and the business deducts lease rental payments as a revenue expense.
How does this compare to a petrol or diesel van?
Petrol and diesel vans typically qualify for the Annual Investment Allowance too (up to its annual limit), which in practice also gives 100% relief in the year of purchase for most small and medium businesses, since the AIA limit comfortably covers the cost of ordinary commercial vehicles โ so the headline relief is often similar; the electric van's advantage is more about running costs, VED and any first-year allowance route staying open even where AIA has been exhausted elsewhere in the business.
Is a double cab pickup treated as a van for capital allowances?
Not automatically. Following HMRC's reclassification, most double cab pickups with a payload of one tonne or less are now generally treated as cars rather than vans for both capital allowances and benefit-in-kind purposes, which is a significantly less generous regime than the van rules described here.
Does claiming the full cost upfront reduce corporation tax immediately?
Yes, for a limited company, a 100% first-year deduction directly reduces taxable profit in that accounting period, cutting the corporation tax bill (at 19%-25% depending on profit level) for that year rather than spreading the benefit over several years' returns.
What happens if the electric van is sold later?
If the van is sold after its full cost was claimed as a capital allowance, the sale proceeds are generally brought back into the accounts as a balancing charge, increasing taxable profit in the year of sale โ so the tax benefit is really about timing (getting relief earlier), not a permanent reduction in total tax paid over the life of the asset.
