Business premises need to gear up for mixed-energy fleets
As we drive into 2026, fleet electrification remains a priority for fleet managers across Europe. The question is no longer whether to support electrification, but how to do so without over-committing too much, too soon.
With regulations, incentives, energy prices and infrastructure varying across European countries, flexibility has become just as important as EV ambition.
That’s why a mixed-energy fleet can provide a transitional solution. While internal combustion engine (ICE) vehicles suit many routes and roles, electric vehicles can fill other logistical gaps.
Here we examine how businesses can effectively manage both technologies side by side, from one single-site to multiple operational bases across borders.
One size rarely fits all
For many businesses, a mixed-energy fleet is a practical necessity.
ICE vehicles remain the prime choice for roles that involve long-distance travel in areas where EV charging infrastructure is not yet well developed. They also provide greater certainty when vehicles are carrying heavy payloads, towing equipment or operating in extreme weather, where EV range can be significantly reduced.
Meanwhile an EV portfolio can showcase green company credentials and help to accelerate corporate environmental goals, as well as offering a lower total cost of ownership (TCO).
However, how to blend these priorities is the challenge.
Are your business premises prepared for a blended fleet?
The most effective starting point is a thorough site assessment. Even within the same organisation, fleets can differ significantly in scale, size and vehicle usage.
Understanding how vehicles currently operate from each site, how long they are on or off-site and how the fleet is used allows operators to make informed decisions about futureproofing their premises.
A localised view is especially important across international fleets, where EV incentive schemes or sustainable building subsidies can vary widely between countries and even between regions.
Designing space that can evolve with your fleet
Functionality is key when it comes to designing a site to suit a mixed fleet. On-site parking, charging stations, manoeuvring space and storage must all be taken into consideration to support both ICE vehicles and EVs. Don’t forget the coffee facilities and rest areas for people waiting for their vehicle to charge too!
By building in adaptable parking layouts, space for future chargers and clear vehicle flows from the outset, fleets can evolve without repeated disruption. Costs can also be saved when the work is incorporated during site upgrades or major redevelopments.
Power planning
Electrical infrastructure is often one of the biggest challenges for fleet premises and also where the risk of over or under-investment is highest.
Rather than installing large numbers of chargers upfront, many fleets prepare their sites so additional charge points can be added later on, as operational needs change and more EVs are required.
Load management systems play a key role in this approach by controlling when and how vehicles charge, ensuring total electricity demand stays within the site’s available capacity. By balancing charging with other site energy use, these systems help fleets avoid costly grid upgrades and higher electricity charges, while allowing EV charging to scale in line with fleet growth.
Supporting ICE while preparing for EVs
As fleets transition, a balance is required between future-proofing premises but also being prepared for the here-and-now.
ICE vehicles will remain part of many fleets for years to come, meaning sites still need to support day-to-day petrol and diesel operations. This includes access to refuelling (at base or nearby), and the storage and handling of vehicle fluids such as oils, coolant, AdBlue and screenwash. Fire safety procedures associated with flammable liquids and exhaust emissions should also be in place.
Keep people in the picture
People and processes play an equally important role in mixed-energy readiness. Clear signage and additional driver training, particularly around EV safety and emergency protocols, will support smoother adoption.
Navigating regulation across borders
Compliance adds another layer of complexity for European fleets. Planning rules, electrical standards and fire regulations vary by country and sometimes by municipality.
Engaging local expertise early can help premises remain compliant as regulations evolve.
Build adaptability into your premises strategy
Ultimately, readiness for a mixed-energy fleet is less about predicting the exact pace of electrification and more about building adaptability into fleet premises.
By focusing on site-specific planning and phased investment, European car and van fleets can support ICE vehicles and EVs side by side while keeping future options open.
Fleet electrification is undoubtedly defined by uncertainty. Maintaining flexible premises means international fleet operators gain a valuable advantage: the freedom to move at the right pace that suits their business model.
