British fleet operators now have a far clearer picture of what electrification does to a cost base. A study by EY and Eurelectric, the federation of the European electricity industry, finds that electrifying corporate cars in the UK could reduce operating costs by up to 64%, while corporate light commercial vehicles could see reductions of up to 38%. Across Europe, the same analysis values the opportunity at as much as €246bn in operating cost savings by 2030, driven by lower energy, maintenance and tax costs.
The findings come from Fleet Forward, a cross-country assessment covering the UK, France, Germany and Sweden. Small and medium-sized enterprises and large operators in Britain are identified as particularly well placed to benefit, thanks to a combination of strong fiscal incentives and charging solutions that are improving quickly.
Corporate fleets account for around 60% of new vehicle registrations in Europe, which gives the finding weight well beyond the balance sheets of individual operators. Company vehicles also return to the second-hand market after three to five years, feeding affordable electric stock into the wider economy.
Where the savings come from
The advantage is largely a per-kilometre story. UK corporate cars show the largest operating cost saving of the four markets analysed, at €0.19 per kilometre, ahead of Sweden at €0.12 and France and Germany at €0.09 apiece. The report attributes this to supportive tax treatment, lower exposure to clean-air charges, better charging infrastructure and favourable urban-charge rules.
Because corporate vehicles cover roughly twice the mileage of privately owned cars, small per-kilometre differences accumulate into material annual figures. Policy stability is singled out as the other half of the picture, giving finance teams something dependable to model against.
Britain leads on corporate cars
Adoption is already well advanced. More than 75% of new corporate car registrations in the UK were battery electric in 2025, one of the highest penetration rates in Europe according to EY analysis. Low Benefit-in-Kind taxation is repeatedly identified in the research as one of the strongest demand levers anywhere on the continent.
That incentive also comes with visibility, with the BiK rate set to rise from 3% to 5% by 2027/28, a trajectory the report treats as one of Europe’s most influential. Leasing arrangements, bundled Fleet-as-a-Service and Car-as-a-Service products, and salary-sacrifice schemes are all credited with lowering the capital expenditure barrier for smaller operators.
Vans hold the next gain
Light commercial vehicles are where the headroom sits. UK electric vans deliver savings of approximately 38% against diesel equivalents, close to France at 40% and Sweden at 45%, and far ahead of Germany at 10%. The Zero Emission Vehicle Mandate for vans, which began in 2025, supports the transition across LCV fleets.
Penetration in the van market remains modest, with battery electric models accounting for 10.4% of all new UK LCV registrations in January 2026 according to the SMMT. For operators running mixed fleets, that gap is best read as unclaimed margin.
Connection queues are being reordered
Connection timelines have been the practical constraint, typically running to around 18 to 36 months. Substantial queue reform is now being implemented, with the Ofgem-approved Connections Reform moving from a “first-come, first-connected” model to “first-ready-and-needed, first-connected”, alongside tougher end-to-end performance obligations on network operators. The reform is designed to prioritise deliverable demand, including EV charging and fleet depots.
Workarounds are already in service while the queue clears. Battery-integrated chargers, smart-charging systems and flexible connection agreements can all reduce lead times and support a faster rollout, according to the report.
Truck grants lead Europe
Heavy goods vehicles sit at an earlier stage, and the numbers reflect it, with only 587 of the 40,504 HGVs registered in the UK during 2025 being zero emission on SMMT figures. Britain does, however, offer some of the highest truck grants in Europe, worth up to €139,000 for the largest vehicles, which makes it an attractive market for heavy-duty electrification.
The economics are beginning to work at the corridor level. Electric trucks can already deliver operating cost savings of 7% to 20% on major European routes when charging strategies are optimised, and depot-first charging combined with active energy management could reduce costs further and accelerate deployment.
First movers take the margin
Barriers remain, and the research names them plainly: high upfront purchase costs and total cost of ownership questions linked to residual value uncertainty. Leasing and salary-sacrifice structures address much of the second concern by passing residual risk to the provider, which explains their prominence in the UK market.
“The findings from EY’s latest report with Eurelectric provide a compelling argument in favour of fleet electrification for UK companies. The cost savings as well as the positive environmental impact businesses can tap into by electrifying their fleets is clear, adding to the significant regulatory incentives in place encouraging companies to adopt cleaner and greener transport. However, as the UK moves from early adoption to mass uptake, the progression of wide-scale fleet electrification will hinge on the speed of infrastructure development, including charging availability, affordability and interoperability.”

Britain enters this phase from the front of the field, with the deepest corporate car adoption, the largest per-kilometre saving of the markets studied, and a grid reform programme built to favour operators with firm plans. The organisations that convert the 64% figure into realised savings will be the ones with depot strategies and connection applications already in motion.
