Electrifying UK fleets could reduce operating expenses by as much as 64%.

Fleet electrification has the potential to reduce operating expenses by as much as 64% for company cars and 38% for light commercial vehicles (LCVs), according to a new report from EY and Eurelectric, the European electricity industry federation.

The study indicates that fleet electrification throughout Europe could result in savings of up to €246 billion in operating costs by 2030, attributed to reduced energy, maintenance, and tax expenses. Small and medium enterprises (SMEs) and larger companies in the UK are particularly well-positioned to gain from this trend due to strong financial incentives and rapidly advancing charging solutions.

Currently, the UK boasts one of the highest rates of battery electric vehicle (BEV) adoption in corporate fleets, with over 75% of new company car registrations expected to be electric by 2025, as per EY's analysis. This growth is largely fueled by low Benefit-in-Kind (BiK) tax rates, which the latest EY and Eurelectric report identifies as a powerful driver of demand in Europe.

Maria Bengtsson, EY UK & Ireland Mobility Leader, stated: “The insights from EY’s new report with Eurelectric strongly advocate for fleet electrification among UK businesses. The evident cost savings and positive environmental effects of transitioning to electric fleets, along with existing regulatory incentives for cleaner transport, are significant. Nevertheless, as the UK shifts from early adoption to widespread acceptance, the future of fleet electrification will depend on the rapid development of infrastructure, including charging availability, affordability, and interoperability. The study also points out obstacles to EV adoption, such as high upfront costs and uncertainties regarding total ownership costs related to residual values.”

The UK’s regulatory environment offers incentives for fleet electrification.

The report highlights the UK’s favorable policy environment, where electric corporate vehicles provide the most significant operating cost benefits compared to other markets analyzed (UK, France, Germany, and Sweden). This advantage stems from supportive tax policies, reduced clean-air charge exposure, improvements in charging infrastructure, and advantageous tax and urban charge regulations.

UK electric vans demonstrate roughly 38% savings compared to diesel, comparable to Sweden (45%) and France (40%), but significantly higher than Germany (10%). In terms of corporate cars, the UK leads in operating cost savings, amounting to €0.19 per kilometer, which surpasses Sweden (€0.12) and France and Germany (both at €0.09).

Additionally, the UK’s BiK tax rate is projected to increase from 3% to 5% by 2027/28, making it one of the most compelling incentives for adopting electric corporate cars. The Zero Emission Vehicle (ZEV) Mandate for vans, effective from 2025, also supports the electrification of LCV fleets. However, the market share of electric vehicles (EVs) in the van segment remains low, with BEVs making up only 10.4% of new UK LCV registrations in January 2026, according to the Society of Motor Manufacturers and Traders (SMMT), indicating the challenges ahead for LCV electrification.

Grid capacity poses a significant challenge.

UK grid connection delays, typically ranging from 18 to 36 months, present a barrier, but reforms are underway that could enhance the benefits of fleet electrification, including increased operational efficiency. Ofgem’s approved Connections Reform shifts from a "first-come, first-connected" system to a "first-ready-and-needed, first-connected" model, along with stricter performance requirements for network operators, to prioritize essential services like EV charging and fleet depots.

The report notes continued challenges in grid connection times across Europe, including the UK, while also recognizing innovative solutions already in place—such as battery-integrated chargers, smart charging systems, and flexible connection agreements—that can shorten lead times and facilitate quicker implementation.

The report emphasizes the UK's leasing models, bundled fleet solutions like Fleet-as-a-Service and Car-as-a-Service, and salary-sacrifice EV schemes as methods to lower capital expenditure (CapEx) hurdles for SMEs.

Although the UK is not part of the Alternative Fuels Infrastructure Regulation (AFIR), the report highlights that long-haul electrification challenges are widespread in Europe, with repercussions for the UK. Despite the early stage of electric truck adoption, the UK offers among the most substantial grants for trucks in Europe, reaching up to €139,000 for larger vehicles, making it an appealing market for electrifying heavy-duty vehicles. Strategies focused on depot-first charging and energy management could significantly cut costs and speed up deployment. However, the UK remains far from meeting its ZEV Mandate objectives for electric trucks, with just 587 of the 40,504 heavy goods vehicles (HGVs) registered in the UK in 2025 being zero-emission, as reported by the SMMT.
