Example fleet case
Board-ready savings view
A live planning panel that shows cost, charger count, and a practical first-pass recommendation before you request quotations.
Fleet of 20£142,000 savings over 5yr
Depot planningCharging stations needed: 8
Assumes 31,000km per vehicle, overnight charging, and published maintenance averages for mixed-use light commercial fleets.
Tool 1
Fleet EV TCO Modeller
Compare 5-year operating cost exposure for internal combustion vehicles and EVs, then see when the upfront premium is recovered through lower energy and maintenance spend.
Fleet fuel cost (ICE, total)
Fleet electricity cost (EV, total)
Total fuel savings
TCO difference (vehicle cost delta + savings)
Break-even year
Maintenance assumptions use £1,400 per ICE vehicle per year and £800 per EV vehicle per year. Use your own service history for a board submission.

Used by teams that need defensible numbers
The tools are designed for early-stage commercial decisions, not marketing decks. Users typically export a first-pass scenario and refine it with actual tariffs and supplier quotes.
“Fleet TCO modeller justified our EV procurement to the board in one page.”
Sandra F., Fleet Manager“Charging infrastructure tool sized our depot installation correctly — matched the electrician's assessment.”
Tony B., Logistics Director“Professional-grade tool that doesn't require a consultant.”

Questions fleet teams ask before funding approval
These answers reflect planning assumptions only. Formal procurement cases should use vehicle-specific quotations, duty cycle data, and infrastructure surveys.
Does the TCO calculator include government grants?
No — grant availability varies by country and changes annually. Subtract applicable grants from the EV purchase price before entering it.
Is 1,400 vs. 800 maintenance cost per vehicle accurate?
These are approximations from published fleet data. EVs have fewer mechanical components and fewer brake interventions because regenerative braking reduces wear. Your actual figures may vary.
Does the charger sizing tool assume all vehicles charge simultaneously?
No — it assumes vehicles are staggered within the charging window. If all vehicles must fully charge in a 2-hour window, significantly more chargers are required.
What grid connection is required for 8 × 7.4kW chargers?
8 × 7.4kW = 59.2kW peak demand. This typically requires a 3-phase supply and an upgraded grid connection — consult a qualified electrician and network operator.
Should I include charging infrastructure capital cost in TCO?
Yes. Add installation cost, often £1,500–£3,000 per wallbox for a professional installation, to the EV purchase side of the comparison.
Can I use this for cars and light vans in the same fleet?
Yes, but mixed fleets should be modelled in separate scenarios. Cars and LCVs have different energy use, acquisition costs, and maintenance patterns that will distort a blended average.
