Planning EV charging points for a company car fleet is a logistics problem before it's an electrical one, and most SME fleet managers get the order backwards.
- Match charger output to dwell time first: 7kW overnight for depot cars, 22kW only where turnaround is under 4 hours.
- Check DNO grid capacity before ordering hardware — this stalls more EV charging point planning for SME fleets than any budget issue.
- Fit telematics before the EV rollout, not after, so range and charge status show up in one dashboard.
- Public rapid charging as a primary strategy is a Skip for fleets over 10 vehicles — cost and downtime both climb.
Why this matters
The UK phases out sale of new purely petrol and diesel cars by 2035, and most SME company car policies are already shifting drivers onto EVs well before that deadline. The mistake isn't going electric — it's installing chargers before working out how the fleet actually moves.
A fleet running mixed EV and diesel vehicles through 2026 needs visibility into both fuel types in one place, which is exactly where managing a mixed EV and diesel fleet with telematics becomes the practical starting point rather than an afterthought. Get the charging infrastructure plan wrong in 2026 and you're paying for it again in 2028 when the next tranche of vehicles converts.
Who this is for
This is for the SME fleet manager running 5 to 50 company cars or vans who has committed to electrifying part or all of the fleet in 2026 or 2027, and who needs a charging point plan that survives contact with real driver schedules — not a spreadsheet built around best-case dwell times.
What to look for in EV charging point planning for SME fleets
Charger power matched to dwell time
A 7kW charger fully replenishes a typical company car battery overnight, which covers the majority of SME depot scenarios where cars park 8+ hours. Installing 22kW or faster units for overnight-only use wastes capital on hardware the fleet doesn't need — dwell time, not driver ambition, should set the spec.
Depot electrical capacity and grid connection
Most SME depots were wired for lighting and office loads, not for charging six to twenty vehicles simultaneously. A Distribution Network Operator (DNO) capacity check before ordering any hardware in 2026 avoids the single most common cause of stalled rollouts: chargers sitting in boxes because the site can't draw the power.
Driver charging behaviour and range anxiety
Drivers who don't trust the charging plan revert to petrol habits — topping up erratically at public rapid chargers, which costs three to four times more per mile than depot AC charging. Planning has to account for how drivers actually behave, not how the policy document says they should.
Reimbursement and home charging policy
SME fleets with drivers charging at home need a clear reimbursement mechanism tied to actual kWh used, not a flat allowance that either underpays high-mileage drivers or overpays low-mileage ones. This is a policy decision as much as an infrastructure one, and it needs settling before the first charger goes in the ground.
Integration with existing fleet telematics
Charging data is only useful next to location, mileage and utilisation data. A fleet already running vehicle tracking should extend that same dashboard to cover charge status and state of charge rather than bolting on a separate charging app nobody checks.
Scalability as the fleet electrifies further
A charging point plan built for the first 5 EVs should not need ripping out when the fleet hits 20. Underground cabling capacity and consumer unit headroom cost more to retrofit than to install correctly the first time.
Top picks for SME fleet charging setups
Depot AC charging with telematics tied in — the steady workhorse. 7kW to 22kW units installed on-site, monitored through the same platform tracking vehicle location and mileage. This works for any SME with a fixed depot and overnight parking, and it's the lowest cost-per-mile option available in 2026. Buy.
Workplace charging scheme with fleet software oversight — the visibility play. Chargers at the office car park, managed through fleet management software built for small businesses so charge sessions, mileage and utilisation sit in one report. Suits SMEs where drivers commute in and park during the working day rather than overnight. Buy.
Home charging with mileage-based reimbursement — the practical fallback. No capital spend on hardware, but reimbursement needs auditing against actual driving data or it becomes a cost leak. Works well for field-based drivers who rarely visit a depot. Consider.
Company car tracking fitted at EV handover — the safe pick. Fitting a vehicle tracker built for company car fleets the same day an EV joins the fleet means charge behaviour, location and utilisation are captured from day one instead of retrofitted six months later. Buy.
Full reliance on public rapid charging networks — the wildcard. No installation cost, no DNO conversation needed, but per-mile cost runs several times higher than depot charging and driver downtime during rapid charge sessions adds up across a fleet. Fine for occasional long trips, not as a primary strategy for more than a handful of vehicles. Skip.
What to avoid
- Over-specifying rapid chargers for a depot fleet. 50kW+ DC units cost far more to install and run than the overnight AC charging most SME company cars actually need.
- Skipping the DNO capacity check. Ordering hardware before confirming grid headroom is the fastest way to have chargers sitting unused for months.
- Treating charging data as separate from fleet tracking. Running a standalone charging app alongside vehicle tracking software means nobody gets a full picture of utilisation, and reconciling two systems eats the time savings the EV switch was supposed to deliver.
Verdict comparison
| Approach | Best for | Power/cost signal | Verdict |
|---|---|---|---|
| Depot AC + telematics | Fixed-site fleets, overnight parking | 7-22kW, lowest cost per mile | Buy |
| Workplace charging + software | Commuter-pattern fleets | 7kW, daytime dwell | Buy |
| Home charging + reimbursement | Field-based drivers | No capex, needs auditing | Consider |
| Tracker fitted at EV handover | Any SME company car fleet | Data from day one | Buy |
| Public rapid charging as primary | Occasional long-distance only | 50kW+, high cost per mile | Skip |
FAQ
How many EV charging points does an SME fleet need?
Plan roughly one charger per vehicle that parks overnight at the depot, though staggered shift patterns can reduce that ratio. A DNO capacity check in 2026 should confirm the site can supply the total load before any units are ordered.
What's the difference between 7kW and 22kW chargers for a company car fleet?
A 7kW charger fully charges a typical company car overnight, while 22kW suits vehicles that need topping up during a working day with limited dwell time. Most SME depot fleets only need 7kW units.
Is home charging reimbursement better than depot charging for SME fleets?
Home charging avoids installation costs but needs mileage-based reimbursement tied to actual kWh usage or it becomes a cost leak. Depot charging costs more upfront but gives tighter cost control across the fleet.
Do I need a DNO capacity check before installing fleet chargers?
Yes — most SME depots weren't wired to supply multiple simultaneous vehicle charges, and skipping this check is the most common reason charging rollouts stall in 2026. Request the check before ordering any hardware.
How does vehicle tracking help with EV charging planning?
Vehicle tracking shows real dwell times, mileage and utilisation patterns, which is what should set charger specification rather than guesswork. Fleets running telematics before the EV rollout make fewer over-spec hardware mistakes.
Should an SME fleet rely on public rapid chargers?
No, not as a primary strategy for more than a handful of vehicles. Public rapid charging costs several times more per mile than depot AC charging and adds driver downtime during charge sessions.
What happens to EV charging point planning as an SME fleet grows?
Cabling capacity and consumer unit headroom installed for 5 EVs often can't support 20 without retrofitting, which costs more than planning for growth from the start. Size the electrical infrastructure for the fleet's electrification target, not just current vehicle count.
Can mixed EV and diesel fleets share one tracking system?
Yes, a single telematics platform can track fuel and charge status for both vehicle types in one dashboard. This avoids the reporting gap that comes from running separate systems for each fuel type.
One last thing
The fleets that get EV charging point planning right in 2026 aren't the ones with the biggest charger budget — they're the ones who ran the DNO capacity check and the telematics utilisation report before ordering a single unit. Sequence beats spend every time on this one.
