Fleet replacement cycles in haulage run seven to ten years, which means a truck ordered in 2030 could still be working in 2040. Now put that arithmetic next to the government’s confirmed dates for ending the sale of diesel trucks: 2035 for the lighter end of the fleet, 2040 for the heaviest artics. The phase-out is not a consultation or a target any more - it is announced policy, and it lands inside the planning horizon of every fleet buying trucks today.
The government’s response to its consultation on ending the sale of new non-zero emission HGVs sets the schedule out plainly. Announced at COP26 in Glasgow: a phase-out date for the sale of new, non-zero emission HGVs weighing 26 tonnes or less from 2035, and from 2040 all new HGVs sold in the UK must be zero emission. The government described the move as putting the UK on course to be the fastest G7 country to decarbonise its heavy goods vehicle fleet.
The weight split matters, and the response is precise about it. The 2035 date applies to rigid vehicles with a gross vehicle weight of 26 tonnes or less, and to articulated HGVs with a gross combination weight of 26 tonnes and under. The 2040 date applies to articulated HGVs with a gross combination weight greater than 26 tonnes. In plain fleet language: rigids and lighter artics go zero emission at new-sale in 2035, and the heaviest artics follow in 2040.
Read the dates carefully: they end the sale of NEW non-zero emission trucks. Nothing in the announcement bans an existing diesel from the road on those dates - the second-hand market, and every truck already registered, carries on. What changes at each date is the showroom: from 2035 you cannot buy a new diesel rigid at 26 tonnes or under, and from 2040 you cannot buy a new diesel artic over 26 tonnes. The used market and the existing fleet then age out over the following decade or more.
That distinction is the difference between panic and planning. Nobody’s current truck becomes illegal in 2035. But every fleet’s replacement programme runs straight into the dates: a fleet replacing a 26-tonne rigid in 2036 will be choosing from zero emission options whether it feels ready or not.
The consultation response acknowledges the edge cases. Alongside the response, government published a call for evidence to identify a potentially limited range of exemptions to the 2035 date for HGVs of 26 tonnes or under - vehicles that may need until 2040 to transition. The response also notes the phase-out will eventually be enforced through regulation, possibly through the same kind of framework being developed for zero emission cars and vans, with consultation on the regulatory detail to follow. So the dates are fixed, but the machinery and the exemptions are still being built - worth watching if your operation runs specialist vehicles.
Three consequences for fleet planning. First, the depreciation assumption: a new diesel rigid bought in the early 2030s sells into a used market where new diesels no longer exist - residual values in the late 2030s are a genuine unknown, and finance deals signed today should acknowledge it. Second, the infrastructure question has a deadline now: depot charging, range, duty cycles and the trials data all stop being theoretical the moment your replacement cycle crosses a phase-out date. Third, the learning curve is the scarce resource: the fleets that ran electric trucks in the 2020s will replace into zero emission confidently; the ones that waited will be learning under deadline.
One honest caveat from the consultation response: the dates are policy, and the enforcement machinery is still being designed. Government signalled the phase-out will be enforced through regulation - possibly the framework being built for zero emission cars and vans - with consultation on the detail to follow. Fleets should treat the dates as fixed and the mechanics as fluid: who counts as exempt, how compliance is measured, and what happens at the margins are all still being written. That is not a reason to wait; it is a reason to plan for the dates while tracking the rules that will define them.
Map your fleet’s replacement schedule against 2035 and 2040 today. Rigid-heavy urban and regional fleets hit the first date; artic-heavy trunking fleets get five more years of new-diesel availability but the same destination. Either way, the next replacement cycle after this one is likely to include zero emission vehicles, and the time to understand where they fit - which routes, which duty cycles, which depots - is before the choice is compulsory, not after.
