Rightcharge has published its 2026 Annual State of Fleet Charging Report, revealing key insights on fleet charging trends and cost-saving opportunities for fleets in 2026.

The report is based on real-world data from tens of thousands of charging sessions and more than 1,000 megawatts of energy delivered to UK fleets during 2025.

The report underscores the clear disparity in ‘fuelling’ costs depending on whether fleets use public or home charging.

Public charging accounted for only 27% of sessions but made up more than half (57%) of total fleet spend due to the heavy premium for convenience. In 2025, the average cost for public charging was 81p/kWh, whereas charging at home cost an average of 25p/kWh. This means businesses relying heavily on the public network are paying more than three times the price for the same amount of energy.

The report also shows the ‘double win’ of lower costs and carbon from smart charging; i.e. timing a charge session when energy is cleaner and often cheaper. While 77% of home charging already happens during off-peak hours, only 43% of public sessions do. By shifting more charging to off-peak periods, fleets can cut their charging-related emissions by up to a third.

And the report shows that fleets that encourage drivers to switch to a dedicated EV tariff can see the rates drop even further to around 6-7p/kWh, unlocking annual savings of up to £1,300 per driver.

A new benchmark for fleets

Rightcharge’s new reports also introduces the ‘blended average unit rate’ as the 2026 industry ‘gold standard’ for measuring the total cost of ownership for electric and internal combustion engine vehicles.

By looking at the average cost across all charging, businesses can get a true picture of their costs and potential savings.

In 2025, the average blended unit rate across the Rightcharge platform was 40p/kWh, equating to 11p per mile.

This shows that electric vehicles are significantly cheaper to ‘fuel’ than diesel at 15p per mile or petrol at 17p per mile.

Charlie Cook, founder and CEO of Rightcharge, said: “Transitioning to an electric fleet brings huge benefits, but optimising your charging can help you save even more money. Our latest data shows a big difference in charging costs across the UK fleets. We’ve published this report to give fleet managers the benchmarks that they need to see the true value of electric vehicles. We’re also excited to announce that we’ll be sharing snapshots from our platform data throughout the year. ”
