Most workplace charging starts as a gesture: two chargers near reception, free to use, installed the year the first director bought an EV. And for a while it works — because demand is two cars.
Then salary-sacrifice schemes and company EV policies do their job. Thirty staff drive electric, the two bays are occupied by 7:45am, someone's started a WhatsApp group to negotiate swaps, and facilities is fielding complaints about the same three cars every day. The perk has become infrastructure — without anyone deciding to manage it as such.
Here's what changes at that point, and the decisions that make workplace charging work at scale.
Decide what the electricity is: perk, benefit, or utility
The foundational choice is commercial, not technical: who pays, and how?
- Free charging is simple and generous — and at scale creates the deepest fairness problems (it's a benefit only capturable by those who win the morning race for bays) plus a possible benefit-in-kind and cost-visibility question your finance team will eventually ask.
- At-cost or subsidised tariffs keep the perk while introducing enough price signal to discourage bay-squatting — and generate the session data that makes costs attributable.
- Market-rate with visitor access turns the car park into a small public charging operation, with everything that implies — including, if chargers are publicly accessible, regulatory obligations.
Any of these can be right. What doesn't survive scale is undecided — free-by-default with no policy, no data and no fairness mechanism.
Fairness is the actual product
At workplaces, the scarce resource isn't kW — it's bays over the working day. The failure mode everyone recognises: cars fully charged by 10am, parked until 5:30pm, while colleagues circle.
The toolkit, roughly in order of escalation:
- Visibility first. A live view of bay status and a queue or booking mechanism removes the information problem that causes most friction. Half of "we need more chargers" complaints are actually "I can't tell when one's free".
- Rotation norms with notifications. "Move within an hour of full" works remarkably well when the platform tells people their car is done — and works terribly as an unenforced poster in the lift.
- Smart allocation. With load management, sharing power across more bays beats rationing a few full-power ones: eight 7 kW points serving the day's dwell time deliver more useful charge than three 22 kW points serving the fastest finger. Most commuter cars need 20–40 miles of range recovered, not a full battery.
- Priority policies, explicitly. Pool vehicles before commuters? Salary-sacrifice drivers who depend on workplace charging before driveway-owners topping up? These are HR-flavoured decisions — better made once, published, and encoded as rules than re-litigated per incident.
The access-control question nobody asks until it bites
Who exactly may charge? Staff — from which entities on a shared campus? Contractors? Visitors? Fleet vehicles overnight? The answer determines the authentication mix (RFID for staff, app or contactless for visitors, Plug & Charge for fleet vehicles) and, on multi-employer sites, lands you squarely in multi-tenant territory: one car park, several organisations, each needing its own users, rates and reports, none seeing the others'.
Landlords and campus operators should treat this as a first-class requirement — retrofitting per-employer separation after the fact is the expensive version.
Reporting: the part finance and ESG will come for
Sooner than you expect, three departments want numbers:
- Finance: cost per employee, per department, per site; benefit-in-kind evidence if charging is free; recharging tenants on shared sites.
- ESG: kWh delivered and mileage electrified for sustainability reporting — workplace charging is one of the few Scope-adjacent numbers a company can measure precisely rather than estimate.
- Facilities: utilisation and reliability to justify (or refute) the next expansion phase with data instead of anecdotes.
This is the strongest argument for running workplace charging on a real platform rather than standalone chargers: the numbers exist, per session, per user, exportable to the systems that need them — instead of living in a vendor app someone in facilities has the only login for.
The takeaway
Workplace charging stops being simple at roughly the moment it starts being valuable. The organisations that get it right make three decisions early — the commercial model, the fairness mechanism, the access boundaries — and pick infrastructure that can report on itself. Everything else (more bays, faster units, smarter scheduling) is iteration on a managed foundation, rather than gestures stacked on an unmanaged one.
