“The bigger the vehicle, the greater the challenge”: Five steps to adopting eHGVs

1. Assess existing operations

Before you invest in electrification, it’s important to understand your existing fleet, infrastructure, and operational data. How do vehicles move onsite? How do they travel between sites? When do they stop and refuel?

Understanding this data is essential to understanding the impact of electrification. This assessment should cover daily mileage, route predictability, payload, dwell times, depot return patterns and the effect of seasonal or peak demand. It can help identify which vehicles and routes are suitable for early electrification, where charging fits into existing schedules, and what operational changes may be required.

2. Identify charging and energy needs

Once you understand how the fleet operates, you can determine the type, number and power of the chargers required. Vehicles that return to a depot overnight may be able to charge over a longer period, while fleets with shorter turnaround times could require higher-powered DC charging. The right approach depends on vehicle specifications, dwell times and how many vehicles need to charge simultaneously.

Charger placement also matters. The design needs to account for vehicle movements, parking arrangements, cable reach and any plans to expand the fleet. Smart charging and load management can help distribute available power between vehicles, prioritise operationally critical charging and reduce unnecessary peaks in demand.

You can then assess these requirements against the site’s existing electrical capacity. Some locations may support an initial deployment without major network work, while others may require a connection upgrade from the local Distribution Network Operator (DNO). Because connection capacity and delivery times vary by location, it’s sensible to explore this early in the planning process.

3. Build the business case

Next, you can build the business case. The commercial assessment should consider the total cost of ownership over the vehicles’ expected service life. This includes vehicle and infrastructure costs, electricity, maintenance, financing, insurance, connection charges, and any required operational changes.

Although eHGVs and charging infrastructure can require greater up-front investment, lower fuel and maintenance costs may offset part of that difference over time. The outcome will depend on factors including mileage, electricity prices, charging patterns, vehicle utilisation and the cost of any site upgrades. Running several scenarios can help businesses understand the conditions under which electrification becomes commercially viable.

There are also wider commercial benefits that are harder to quantify. An eHGV fleet can help you win business from companies that need to demonstrate Scope 3 emissions reduction. This is especially important in highly-regulated areas such as the public sector. An ICE fleet could even be a barrier to entry for a major tender, with the contract specifying that suppliers must make deliveries using eHGVs.

Evaluating cost also involves assessing available funding. The second window of the government’s Depot Charging Scheme is expected to open between 28 October 2026 and 29 January 2027. This gives you the opportunity to secure up to £1 million in funding for charging infrastructure. This is a great opportunity to offset as much as 70% of the up-front costs associated with installation, and can help lay the foundations for future transformation.

4. Invest in vehicles and infrastructure

Once you’ve assessed your operations, charging requirements, costs and funding options, you can begin putting the plan into practice. Fleet electrification is a broader change programme, not simply a vehicle procurement exercise, so phase the transition carefully and support it with clear responsibilities across fleet, facilities, energy, and depot teams.

Begin with vehicles and routes that offer a clear, repeatable use case. An initial deployment can help validate real-world range, charging schedules, energy consumption and operational impact before committing further investment. It can also help confirm that the selected vehicles and charging infrastructure work effectively together under day-to-day operating conditions.

Driver and depot-team engagement should form part of the programme from the outset. Training should cover how and when vehicles are charged, how to report issues, and how to handle changes to established routines. Clear communication and simple reporting processes can help identify problems early and encourage consistent use of the vehicles and infrastructure.

5. Optimise and scale

Once the first vehicles are operational, use the data they generate to refine your approach. Measures such as vehicle availability, energy consumption, charging performance, operational disruption and whole-life cost can help you understand what is working and where changes may be needed.

This could mean adjusting charging schedules, refining routes, improving driver guidance or changing how available power is distributed between vehicles. Smart charging and load management can become increasingly important as the fleet grows, helping prioritise vehicles by operational need and manage demand across the site.

The results can then inform a phased expansion plan. Consider which vehicles and routes should be electrified next, how charging demand is likely to increase and whether additional chargers, electrical capacity or site changes will be required. Building flexibility into the initial design can make it easier to add vehicles and infrastructure over time, rather than treating each new deployment as a separate project.

Regularly reviewing vehicle technology, charging options, operational requirements and available funding will also help keep the plan relevant as the market develops. This makes electrification an ongoing process of learning and improvement, rather than a one-off investment.

The sooner, the better

Fleet electrification is already taking place. For example, Royal Mail has undertaken a 6-month eHGV trial and Gridserve has opened the UK’s first public eHGV charging hubs. There’s a clear direction of travel, and we’re likely to see many more developments in the coming months and years.

Getting ahead also offers a practical advantage. Developing a business case, assessing site capacity, securing grid connections and designing charging infrastructure can take time, particularly for larger fleets. Starting early gives organisations more flexibility to evaluate options, secure funding and phase implementation in a way that minimises operational disruption.

While the challenges associated with eHGV adoption are greater than those faced when electrifying cars and vans, the process is fundamentally the same. By understanding your operations, planning your energy requirements, building a robust business case and taking a phased approach to deployment, you can create a clear pathway towards low-carbon logistics.
