The sticker price of an electric HGV is still the industry’s favourite reason to wait. The plug-in truck grant exists to attack exactly that number: the government’s zero-emission vehicle grant scheme for trucks discounts eligible vehicles at the point of purchase, and the tiers on the current list - £15,000, £37,000, £52,000 and £81,000 - scale the support with the size of the truck. For a fleet running the numbers on its first electric artic, £81,000 off the list price changes the conversation materially.
The grant tiers published on the government’s trucks eligibility list follow vehicle weight, so the support lands where the price gap is largest. A small zero-emission truck at the light end qualifies for £15,000; the heaviest eligible trucks - the large rigids and artics where the battery and the price are both biggest - qualify for £81,000. The middle tiers at £37,000 and £52,000 cover the bands in between. The government’s trucks page lists which specific vehicles are eligible at which tier, and the list is the reference that matters: eligibility is per vehicle model, not per category, so a procurement exercise starts with the list, not with the brochure.
The scheme’s shape is familiar from the van and car grants that preceded it: the discount is applied at purchase through the dealer or manufacturer rather than claimed back afterwards, and it is capped so the support is spread across many operators rather than absorbed by a few large orders. The policy intent is plainly to seed the market - get zero-emission trucks working in real fleets, in volume, until the price gap closes on its own.
A grant is a subsidy on the capital line, and capital is only one line. The honest comparison for any fleet is whole-life cost per vehicle or per mile, where electric trucks argue back against the higher sticker price with cheaper energy per mile, fewer moving parts to maintain, and exemptions from charges that diesel pays in an increasing number of places. Against that stand the real constraints: range against the duty cycle, charging infrastructure at the depot - which is a project with its own costs and lead times, involving grid connections that can take longer than the truck delivery - and residual value, where the used market for electric HGVs is still too young to price confidently.
The duty cycle question decides most cases. Urban and regional work with predictable daily mileage and overnight depot return is the grant’s sweet spot: the truck’s range is comfortable, charging happens at home base, and the energy savings accumulate on high-utilisation urban miles. Long-haul trunking remains the hard case, where range and en-route charging still constrain the operation. Fleets that map their vehicles by duty cycle before shopping tend to find the obvious first candidates - the shunters, the urban rigids, the back-to-base artics on repeatable runs - and those are exactly where grant-funded purchases make most sense.
Nobody should order the truck before solving the power. Depot charging for even a modest electric truck fleet means significant electrical capacity, and the practical sequence is: assess the site’s grid connection early, design the charging layout around how the vehicles actually stand overnight, cost the upgrade alongside the vehicles, and only then sign orders. The grant helps with the truck; the substation is your own project. Fleets caught out by this ordering mistake own expensive trucks waiting on electrical work - the reverse of the plan.
The grant sits inside a wider push: zero-emission vehicle mandates for manufacturers, tightening urban access rules, and customers asking carriers for emissions data with rising specificity. None of that obliges any fleet to buy electric this year, but it does mean the question is moving from “if” to “when and where first” - and grant schemes at their most generous tend to be early, while the market is being seeded. The fleets that will look cleverest in five years are the ones that used the support while it was rich, on the duty cycles where the technology already wins, and learned the operational lessons - charging rhythms, driver training, range management - while their competitors were still waiting for the perfect truck.
Finally, a note on timing that procurement teams should pin to the wall: grant schemes change. Eligibility lists are revised, tiers are reviewed, and schemes close when their purpose is served or their funding is committed - the only version of the truth that matters is the current government list on the day the order is placed. Fleets that build a business case on a tier printed six months ago, or assume a grant will survive into next year’s budget cycle, are planning on weather. Check the list at decision time, secure the vehicle’s place in the scheme as the manufacturer advises, and treat any grant as real only when the paperwork says so.
