Should Your Business Lease or Buy an Electric Vehicle? The Real Numbers for 2026
Every fleet decision maker asks the same question sooner or later, should the business own its vehicles outright or lease them. With electric vehicles, that question carries more weight than it ever did with petrol or diesel, because the tax treatment, the VAT rules, and the depreciation risk all behave differently once a battery is involved. Get the structure wrong and you can hand back thousands of pounds a year in relief you were entitled to.
This article sets out the actual mechanics, tax by tax and pound by pound, rather than the usual generic pros and cons list. Every figure below is sourced, and the sources are listed in full at the end.
The Uncomfortable Starting Point: Purchase Has a Tax Advantage Leasing Cannot Match
Most leasing content skips this, but it needs saying plainly. If your business buys a new, unused, fully electric car outright or via hire purchase, you can currently claim a 100% First Year Allowance, deducting the entire cost of the vehicle against taxable profits in the year of purchase, rather than spreading relief over several years. This relief has been extended in the Autumn 2025 Budget and now runs to 31 March 2027 for corporation tax purposes and 5 April 2027 for income tax purposes.
Crucially, this allowance is only available where the business actually owns the asset. If the vehicle is leased under an agreement where the business never takes ownership, the 100% First Year Allowance simply does not apply. On a £45,000 electric car, that is a £45,000 deduction against taxable profits in year one if you buy, versus none of that specific relief if you lease.
Used electric vehicles do not qualify for the 100% First Year Allowance either way, they fall into the main capital allowances pool and are relieved through writing down allowances instead, and from April 2026 that main rate dropped from 18% to 14% per year on a reducing balance basis. So the FYA argument applies specifically to new vehicles bought outright, not to used stock.
That is the strongest card outright purchase holds. Everything else in this comparison tends to favour leasing, sometimes significantly.
Benefit in Kind Tax Is Low for EVs Either Way, But the Numbers Still Matter
If a director or employee has personal use of the vehicle, Benefit in Kind tax applies whether the car is leased or purchased, the treatment does not change based on how the business acquired the vehicle. For fully electric cars the rate is 4% of the car's list price for the 2026/27 tax year, rising to 5% in 2027/28, 7% in 2028/29, and capping at 9% in 2029/30. That compares with a maximum of 37% to 39% for petrol and diesel vehicles over the same period.
On a £40,000 electric car at the 2026/27 rate, the taxable benefit is £1,600, costing a higher rate taxpayer around £640 a year in income tax, alongside employer Class 1A National Insurance on the same benefit. That is a genuinely low cost of providing an EV as a benefit, and it applies identically whichever route the vehicle was acquired through.
VAT Recovery Is Where Leasing Pulls Ahead
This is the section most purchase focused comparisons leave out entirely.
If your business buys a car outright and any private use is possible, even by a director occasionally driving it home, HMRC treats the input VAT on the purchase price as irrecoverable. Full recovery is only available in narrow circumstances, pool cars with no private use permitted, driving instruction vehicles, taxis, or vehicles held as stock by a dealer. For most ordinary business cars, that means 20% VAT on the purchase price, gone, with no reclaim.
Lease a car instead and the position improves. HMRC's standard rule allows 50% of the VAT on the lease finance element to be reclaimed, reflecting an assumed level of private use even where the car is mainly used for business. If the lease includes a maintenance package, the VAT on that portion is reclaimable in full, since maintenance is treated as a genuine business cost rather than a private benefit.
On a £500 a month lease payment including VAT, that 50% recovery is a real, recurring saving that purchase simply does not offer under normal use.
Cash Flow and Balance Sheet Impact
Buying a vehicle outright, even with the 100% First Year Allowance softening the tax bill, still means finding the full purchase price upfront or taking on a loan secured against the business. That is capital tied up in a depreciating asset, capital that is not available for stock, hiring, marketing, or simply weathering a slow quarter.
Leasing converts that lump sum into a fixed monthly cost, which is easier to forecast and does not require a large draw on cash reserves or credit lines. For growing businesses in particular, preserving working capital and existing credit facilities for the activities that actually generate revenue is often worth more than the tax relief on ownership.
Residual Value Risk Sits With Whoever Owns the Car
This is the point specific to electric vehicles that did not really exist in the petrol and diesel world in the same way. Battery technology, charging speeds, and government incentives are all moving quickly, and a three year old EV can lose value faster or slower than expected depending on how the market shifts in the meantime.
Buy the car outright and your business carries that residual value risk entirely. If the used EV market has softened by the time you come to sell, that loss sits on your balance sheet. Lease the car and, provided you have not exceeded agreed mileage or condition terms, that residual value risk sits with the leasing company, not with you. Given how genuinely difficult it still is to predict used EV values three or four years out, this is not a small consideration.
The Road Charge Coming in 2028
From April 2028, a new mileage based Electric Vehicle Excise Duty will apply to electric and plug in hybrid cars, charging drivers per mile alongside existing Vehicle Excise Duty, with electric vehicles paying half the equivalent fuel duty rate applied to petrol and diesel<sup>10</sup>. This applies to the vehicle regardless of whether it is leased or owned, but it is worth factoring into any five year running cost comparison you build today, since it will affect both scenarios similarly and should not be used as an argument for one route over the other.
Worked Example: A £45,000 Electric Hatchback Over Three Years
The sections above set out the mechanics. Here is what they actually do to the numbers, using a profitable limited company paying the 25% main rate of corporation tax, on a £45,000 electric car including VAT.
Buying outright
The company pays £45,000 upfront. Because private use is possible, the £7,500 of VAT within that price is not reclaimable, so it becomes part of the cost for capital allowance purposes. The full £45,000 qualifies for the 100% First Year Allowance, producing a corporation tax saving of £11,250 in year one. Net cost after tax relief, £33,750, for an asset the company now owns outright.
Assume a fairly cautious residual value of around £18,000 after three years, roughly 40% of the original price, reflecting the genuine uncertainty in used EV values discussed above. Net three year cost of ownership, after accounting for that residual value, works out at around £15,750.
Leasing instead
The same car on a three year Business Contract Hire agreement at, say, £650 a month including VAT costs £7,800 a year, £23,400 over the full term. Half the VAT within each payment, roughly £650 a year, is reclaimable, and the full lease payment is deductible as a revenue expense against profits at 25%, saving a further £1,950 a year in corporation tax. Net annual cost after relief, around £5,200, or roughly £15,600 over three years. At the end of the term, the car goes back, there is no asset and no residual value risk either way.
What this actually shows
On these illustrative figures the two routes land within a few hundred pounds of each other over three years, purchase at roughly £15,750, leasing at roughly £15,600. That is not a coincidence so much as a reminder that the FYA advantage on purchase is largely offset, over time, by the VAT and revenue relief advantages leasing carries. The genuine difference is not really the headline cost, it is where the risk sits. Buy, and the £18,000 residual value assumption is yours to be wrong about. Lease, and it is the leasing company's problem.
This example ignores financing interest if the purchase is funded by a loan rather than cash, ignores any maintenance package bundled into the lease payment, and uses a single illustrative lease rate and residual value, both of which will vary meaningfully by vehicle, mileage, and term. Treat it as a way of understanding the shape of the comparison, not a substitute for a quote against your own numbers.
If personal use applies, Benefit in Kind tax sits on top of either scenario identically. At the 2026/27 rate of 4%, a £45,000 car creates a taxable benefit of £1,800, costing a higher rate taxpayer around £720 a year in income tax, plus employer Class 1A National Insurance at 15% on the same figure, around £270 a year, payable by the business regardless of whether the car is leased or owned.
Flexibility and Fleet Management
Beyond the tax mechanics, there is a practical business case for leasing that is easy to underweight. Leasing typically bundles maintenance, and sometimes servicing and tyres, into a single predictable monthly figure, removing a layer of admin from a business that would rather focus on its core operations than fleet management. It also makes refreshing the fleet straightforward at the end of a contract, which matters more with EVs than it did with combustion vehicles, given how quickly range, charging speed, and efficiency are improving generation to generation.
This shift shows up clearly in the industry data. Business Contract Hire is now the largest single segment of the British Vehicle Rental and Leasing Association's leasing fleet, which reached 1.94 million vehicles, with electric vehicles the single most popular fuel type among new additions in recent quarters. The BVRLA attributes much of that growth directly to the Benefit in Kind regime now being confirmed through to the 2029/30 tax year, giving businesses the planning certainty to commit to electric fleets rather than waiting to see how the tax treatment settles.
At the end of a lease, vehicles are assessed against the BVRLA's Fair Wear and Tear Guide, a standardised industry benchmark most leasing companies use to determine what counts as normal use versus chargeable damage. It is worth reading before you sign, since it sets out exactly what condition the vehicle needs to be returned in.
Ownership, by contrast, gives you an asset you can use for as long as you want, modify as you see fit, and eventually sell or trade in on your own timeline, without being bound by a leasing company's mileage caps or condition requirements.
So Which Should You Choose
Neither route is universally correct, but the decision tends to fall out fairly clearly once you know your own numbers.
Purchase tends to make more sense where your business is profitable enough to make full use of the 100% First Year Allowance in the year of purchase, has the cash or credit available without straining working capital, and is comfortable carrying residual value risk on an asset class that is still finding its long term depreciation curve.
Leasing tends to make more sense where preserving cash flow and credit capacity matters more than an upfront tax deduction, where the VAT recovery on lease payments is meaningful to your VAT position, where you want maintenance and fleet admin bundled into one predictable cost, or where you would rather not carry the residual value risk on a fast changing vehicle category.
For many small and medium businesses, particularly those growing quickly or managing multiple vehicles, the combination of VAT recovery, predictable monthly costs, and someone else carrying the depreciation risk tends to outweigh the one year tax hit of forgoing the First Year Allowance. But if your business has the profits to use that allowance in full and the cash to fund the purchase without disruption, buying outright is a genuinely strong option that deserves more attention than it usually gets in leasing focused content.
Whichever direction you are leaning, it is worth running the actual numbers for your specific business, your profit position, your VAT status, and your cash flow, rather than following a generic rule of thumb. That is the calculation we help business owners work through every day.
