UK Fleets Accelerate Toward Net‑Zero with Record EV Uptake

Welcome to Net Zero News, your daily briefing on the UK’s transition to a low‑carbon future.

The UK’s transport sector is making notable strides on the path to net‑zero, with electric vehicle (EV) adoption across fleets rising sharply and policy measures stepping in to accelerate the transition.

In the first six months of 2025, registrations of zero‑emission Heavy Goods Vehicles (HGVs) surged 59.1 % compared to the same period the previous year, reaching approximately 183 new units marking a growing appetite for clean heavy transport despite representing only around 1 % of the market share. This upward trend continued into the third quarter, with zero‑emission HGV uptake jumping a further 341.2 % to 225 units, equivalent to a record 2.4 % market share. Year‑to‑date figures reached 408 units, up 145.8 % compared to 2024.

Bus electrification is also accelerating. The number of zero‑emission buses in use across Britain rose by an impressive 81.8 % in the past year, totalling 3,494 units and making up nearly 4.9 % of the bus parc. Alongside buses, light commercial vehicles are also going electric: battery‑electric vans increased by 31.6 % to 80,476 units, accounting for 1.6 % of the national fleet.

London continues to lead local fleet greening efforts. Transport for London (TfL) has seen more than 2,000 zero‑emission buses added to its network about one‑fifth of its 9,000‑strong fleet with the target of achieving a fully zero‑emission bus fleet by 2030. TfL’s climate actions have also earned validation from the Science Based Targets initiative (SBTi), with firmed‑up commitments to cut Scope 1 and 2 emissions by 90 % by 2030, Scope 3 emissions by 45 % by the same year, and an overarching net‑zero target by 2040.

Private sector fleets are following suit. Marks & Spencer has introduced 85 low‑ or zero‑emission vehicles into its supply chain fleet, including five battery‑electric HGVs and additional trucks running on biomethane derived from waste, covering nearly 10 % of its total transport fleet. Royal Mail slashed its emission rate per parcel by 20 %, thanks to the deployment of 1,900 electric vans, widespread use of biofuel (HVO), and halving air travel in its operations. The company also shared plans for 1,800 more electric vans during the coming year and has already surpassed 7,000 EVs in its fleet.

Technology is also helping fleets to decarbonise intelligently. A new AI‑powered decarbonisation planning report has been launched that uses telematics data to identify which vehicles can switch to alternative fuels, optimise routes, and assess charging infrastructure needs providing detailed transition planning in days and reducing cost and complexity. Meanwhile, Hitachi ZeroCarbon has introduced an all‑in‑one EV fleet management platform offering integrated charging management, battery optimisation, financing, and decarbonisation strategy support tailored to differing fleet needs.

On the regulatory front, the UK Government has injected an additional £18 million into the Plug‑in Truck Grant for 2025/26, giving up to £120,000 discounts for new electric trucks and launching a consultation on phasing out non‑zero‑emission HGV sales by 2040 providing operators with long‑awaited clarity to invest with confidence. Grants for vans and trucks have also been extended through April 2027, offering continued support to businesses planning EV shifts.

Meanwhile, data reveals a significant disparity in adoption across city fleets. In Bristol, EVs make up 44.5 % of local authority fleet vehicles, followed by Liverpool (43.3 %) and Leeds (27.8 %), while Transport for London’s own vans and HGVs remain just 3.2 % electric highlighting that local leadership can vary greatly in decarbonisation progress.

What this means:

The UK’s transport sector is clearly gaining momentum in fleet electrification, with notable gains in buses, vans, and HGVs. Policy support, such as grant funding and regulatory roadmaps, is giving fleets the confidence to invest in zero‑emission vehicles. Major operators are demonstrating that operational shifts deliver tangible carbon reductions, whether through EVs, biofuels or integrated operational strategies.

However, the disparity in uptake across regions underscores that progress depends on local commitment, charging infrastructure availability, and supportive governance. Accelerating decarbonisation will require continued technology innovation, infrastructure planning, and aligning incentives across all fleet types from public transport to private logistics.
