Financing an electric fleet: EVs, HGVs and depot charging

The headline barrier is price. An electric van typically costs more to buy than the diesel model it replaces, and the gap is larger again for electric HGVs, where the technology is newer and volumes lower. For an operator replacing several vehicles at once, that difference multiplied across the fleet is a serious call on capital.

The running cost picture can be more favourable, with lower energy cost per mile and reduced maintenance on a simpler drivetrain, but those savings arrive gradually over years while the purchase premium lands on day one. That timing mismatch, a big cost now against savings spread over the vehicle's life, is exactly the kind of gap that finance is designed to bridge, which is why how you fund the switch matters so much.

You rarely need to find the full premium in cash. Asset finance and leasing both spread the cost of electric vehicles over a typical term of two to five years, so you pay as the vehicle earns rather than up front.

• Hire purchase spreads the cost with a view to owning the vehicle at the end, which suits operators who expect to keep vehicles for the long haul.
• Leasing is a rental over an agreed term, often with the vehicle handed back at the end, which keeps you off the hook for its future resale value.

Rates vary by the age of the asset, the deposit, the term and the strength of your business, so they are worth comparing rather than assuming. The right choice depends heavily on how confident you are in what the vehicle will be worth at the end of the term, which brings in residual values.

A residual value is what a vehicle is expected to be worth at the end of the finance term. For diesel trucks this is well understood after decades of resale data. For newer electric HGVs it is far less settled: battery life expectations, future technology, charging standards and demand for used electric trucks are all still developing, so the used market is harder to predict.

That uncertainty pushes many operators toward leasing for their first electric vehicles, because a lease can place the risk of the future value with the finance provider rather than with you. If the used value turns out lower than hoped, that is the provider's exposure, not yours. Where you are confident about long-term use and want eventual ownership, hire purchase may still suit, but go in with clear eyes about resale uncertainty and take your own advice on how it affects your accounts.

An electric fleet is only as usable as the power behind it. Depot charging is a project in its own right, and often a substantial one: chargers, the groundworks and cabling to install them, and sometimes a grid connection upgrade to bring enough power onto the site. For a yard running several HGVs overnight, the electrical capacity required is significant.

The good news is that this is fundable. The chargers themselves are assets that can be funded through asset finance, and the associated installation and works can often be included in the funding package rather than paid for separately in cash. If you own your depot, larger site works can also sit alongside property funding. Planning the charging spend into the transition budget from the start, rather than treating it as an afterthought, keeps the whole project affordable.

Comparing an electric vehicle to a diesel one on purchase price alone gives a misleading answer. The fair comparison is total cost of ownership across the whole time you run the vehicle. That means adding up the real costs on both sides:

• The purchase or finance cost, including the electric premium
• Energy cost per mile, electricity against diesel, over your actual mileage
• Maintenance and servicing, often lower on electric drivetrains
• Charging infrastructure, apportioned across the vehicles it serves
• Expected residual or end-of-term value, and its uncertainty

Run over several years, a higher upfront cost can be partly or wholly offset by lower running costs, but this depends entirely on your mileage, duty cycles and energy prices. Build the comparison on your own numbers, and confirm the accounting and tax treatment with your accountant before you commit.

Government grants and incentives have supported electric vehicle and charging adoption, and they can materially change the sums. The catch is that the schemes, eligibility rules and amounts change over time, and some open and close at short notice. For that reason we do not quote figures here.

Before you build a business case, check the current schemes and eligibility on gov.uk or with the relevant scheme administrator, and confirm what applies to your vehicle type and your depot works. It is worth understanding what support is genuinely available before you commit to a purchase order, because timing an order around an open scheme can improve the numbers. Treat any incentive as a bonus that sharpens an already sound total cost of ownership case, rather than the thing the whole decision rests on. None of this is tax advice, so take your own on how grants affect your position.
