Cable-Ready or Van-Ready? A Depot Electrification Audit for UK Despatch Teams
Electric van adoption is frequently framed as a choice between models, ranges and monthly lease rates. For a small UK despatch fleet, that framing is incomplete. The decisive questions usually begin when the vehicle returns to base: where it parks, when it can charge, how much payload it carried and whether the site's electrical supply can support the next five years of operations. In the closing months of 2026, with more operators testing electric vans on real parcel rounds, a depot-first audit is a more useful exercise than a brochure comparison.
Begin with the round, not the range
Range figures are a starting point, not an operating plan. The first evidence to gather is eight to twelve weeks of telematics by van and by route. Look at the distribution of daily mileage, not just the average. Record start and end times, payload, stop density, terrain, return-to-base patterns and the days when a van performs multiple runs. A vehicle that averages 45 miles a day across 30 stops may be well suited to electrification. One that covers 180 miles across rural routes with a full load may not be. Winter conditions, heating, ancillary equipment and battery health all reduce the margin between a comfortable round and a tight one.
The overnight charging calculation
Most SME despatch fleets will rely on overnight charging at the depot. The calculation is straightforward but easily underestimated. Estimate nightly energy need per van by dividing expected daily miles by realistic miles per kWh, then add a margin for heating, cooling, ancillary equipment and battery degradation. Actual efficiency should come from trial data, not a best-case laboratory figure.
The next question is whether the site can deliver that energy within the available window. A single 7kW charger can replenish roughly 50 to 60 kWh over an eight-hour period, but only if the van is plugged in for the full window and the charger is available. For a fleet with late returns and early starts, the usable window may be five hours. Charge point count, cable management, parking layout and load management all matter as much as the nominal charging speed.
Where the grid becomes the constraint
Electrical capacity is not uniform across UK business premises. A depot on an established industrial estate may have more headroom than a yard converted from a commercial unit with a domestic-style supply. Before ordering vans, check the site's maximum import capacity, existing peak load, spare capacity, metering arrangements and the condition of switchgear. A qualified electrical contractor should confirm what can be added without an upgrade, and what would trigger a distribution network operator application. Connection upgrades can take months and carry significant cost. They belong in the business case, not in a post-purchase surprise.
Peak season exposes every weak point
December is the audit's stress test. Volumes rise, vans return later, agency drivers join and the overnight window shrinks. A charging plan that works in a quiet week may fail in the peak. Simulate a peak week using last year's despatch data: add the extra routes, extend shift end times and reduce the charging window. Ask what happens if one charger is out of service, if a van arrives with 20% charge rather than 50%, or if a driver forgets to plug in. The answers may include a smaller number of electric vans in the first phase, a public charging contingency or a retained diesel vehicle for exceptional routes. None of these is a failure of ambition; they are evidence of operational realism.
Driver handover is a despatch process
Charging discipline should be designed into the end-of-shift routine, not left to individual habit. That means a named charger allocation, a simple plug-in check at key handover, a fault-reporting route that reaches the depot manager before the next morning, and a clear rule for who moves a van once charging is complete. Telematics and charge point software can confirm plug-in events, but the process still needs an owner. In small fleets, the risk is rarely sabotage; it is a busy driver leaving the yard after a long day.
The total cost line that is easy to miss
Total cost of ownership comparisons should include the vehicle, energy, maintenance, tyres, insurance, charge point hardware, installation, connection works, software subscriptions, driver training and downtime. Residual values and lease terms need to be tested against the intended holding period. A low monthly lease can be outweighed by an electrical upgrade, while a higher upfront cost may be recovered through lower energy and servicing costs. The comparison should be run for the fleet's actual duty cycle, not an average annual mileage figure.
A practical audit sequence
- Pull eight to twelve weeks of telematics data by van and route.
- Map return-to-base times and the realistic charging window for each vehicle.
- Calculate nightly kWh need per van with a winter margin.
- Survey parking, charger locations, cable routes and site safety.
- Ask an electrical contractor to confirm spare capacity and upgrade risk.
- Model a peak week with late returns, agency drivers and charger downtime.
- Set a driver handover process with named owners and a fault route.
- Build a total cost model that includes infrastructure, downtime and training.
- Trial two or three vans before committing the wider fleet.
- Review after 90 days against real energy, availability and route data.
The electric van question is not whether the technology can work. For many UK despatch fleets it can. The more useful question is whether the depot, the route pattern and the peak-season plan are ready for it. An audit that starts at the yard gate will produce a more credible answer than a comparison of brochure ranges. In 2026, that is the difference between a headline commitment and an operating decision that survives the Christmas rush.
