The Rightcharge Annual Report: State of fleet charging 2026 is here, showing the real cost of running electric vehicles (EVs) based on tens of thousands of fleet charging sessions. We’ve analysed the Rightcharge platform data to show you exactly where UK fleets are spending money and cutting their EV charging costs.
Comparing costs for ‘fuelling’ EV and ICE vehicles
In 2025, the average blended cost of electricity across UK fleets sat at 40p/kWh. The typical EV efficiency is 3.5 miles per kWh, and the price to ‘fuel’ an EV sits at 11p per mile. In comparison, internal combustion engine (ICE) vehicles cost 17p per mile for petrol and 15p per mile for diesel.The cost savings for an EV are hard to ignore.
Cutting fleet charging costs
Location is the biggest factor for cutting charging costs. Home charging averaged 25p per kWh, while public charging sessions sat at 81p. Despite public charging making up only 27% of sessions, it accounted for 57% of total fleet charging spend in 2025.
Moving EV charging sessions from the public network to home charging is a great lever for cutting costs.
Home charging saved The AA £1,000 annually, per driver
The AA switched to Rightcharge, removing the admin and inaccuracies of manual home reimbursements. Their drivers now connect home chargers, energy tariffs and vehicles to Rightcharge’s platform. The platform calculates the exact home charging costs and sends reimbursements directly to their energy accounts.
The data showed that 82% of The AA’s charging now happens at home. By moving away from the public network, The AA has saved up to £1,000 per driver, per year. Drivers who swap to EV tariffs, with rates between 6-7p per kWh, can reach savings of up to £1,300 annually.

Linking cost savings and carbon reduction
Cutting costs often goes hand in hand with lower emissions. Cheaper electricity tariffs, such as EV tariffs, are available during off-peak periods when grid demand is low and it relies more on renewable sources, such as wind and solar.
In 2025, 46.2% of the energy delivered to Rightcharge’s fleets was renewable. One fleet, Angus Soft Fruits, reached a renewable energy share of 83%, with 78% of their sessions falling into low-carbon periods. About a quarter of fleet charging still occurs when the grid relies on dirtier energy sources. Shifting these sessions to off-peak windows has the potential to cut the fleet’s carbon impact by up to a third.
The blended Unit Rate: The fleet financial North Star for 2026
The blended Unit Rate is the most important financial metric for fleet managers in 2026. Fleets shouldn’t worry about the occasional high-cost public charge. Monitor the average charging costs across all sessions to get a clear understanding. In 2025, the blended unit rate sat at 40p per kWh for UK EV fleets.
Takeaways:
EVs are already cutting costs for fleets in the UK. The 2025 platform data shows a big opportunity for fleets to reduce these costs even further.
Check out the top takeaways from the Rightcharge Annual Report: The state of fleet charging 2026:
- Prioritise home charging for savings of up to £1,300: Moving a vehicle from public charging to home charging saves up to £1,00 annually per driver, increasing to £1,300 when using EV tariffs.
- Implement smart scheduling for 30% carbon reduction: Match home charging with off-peak windows, when the grid is greenest, to cut carbon by up to a third.
- Use ‘Blended Unit Rate’ as your financial North Star: Monitor the blended unit rate across your entire fleet rather than individual high-cost sessions to maintain a clear view of fleet spend.
