Business EV charging solutions: how salary sacrifice transforms fleets

Businesses moving to electric fleets tend to solve charging infrastructure first: workplace chargepoints, depot charging, maybe a fleet card for public top-ups. What gets overlooked is the cost the driver themselves carries, and that gap is often where an EV transition stalls.

The three places business charging solutions usually focus on

Most fleet EV charging strategy covers:

1. Workplace charging, installing chargepoints at depots or offices
2. Public network access, usually via a fleet charging card for on-the-road top-ups
3. Home charging reimbursement, paying drivers back for charging done at home

Each of these solves access. None of them solves cost fairly, because none of them gives the driver any tax advantage on money they are spending to run the vehicle.

Why access is not the same as affordability

A driver can have a workplace charger, a fleet card and a home wallbox and still be paying full price for every kWh out of taxed income. Compare that to a company car driver who gets the car itself through salary sacrifice at a discount, and the imbalance is obvious: the vehicle is subsidised, the fuel is not.

Salary sacrifice charging fixes this by treating charging cost the same way the lease is already treated: deducted from gross pay before tax and National Insurance. That is a 20 to 50% saving on charging depending on tax band, on top of whatever infrastructure the business has already built.

How it fits with existing infrastructure

Salary sacrifice charging does not replace workplace chargers or public charging cards, it sits underneath them as the payment layer:

• At home: charging cost is captured and added to the monthly statement
• At work: sessions on company chargepoints are recorded the same way
• In public: the app and charge card, powered by Plugsurfing, cover 76,000+ chargers across the UK

One monthly cost, one payroll deduction, regardless of where the charging happened. That is a meaningfully simpler experience than juggling a home reimbursement claim, a fleet card statement and a workplace charger log separately.

The business case, not just the employee case

For HR and fleet teams, the case is not purely about employee saving. Employer National Insurance is also saved on the amount sacrificed, and administration is lighter because there is no reimbursement claim process to run for personal charging. The scheme bolts on to any existing EV salary sacrifice or company car arrangement without renegotiating the underlying lease.

It also removes a source of quiet dissatisfaction. Drivers without home chargers, roughly nine million households across the UK, end up paying the most for charging under a workplace-and-fleet-card-only approach, because they rely more heavily on public rapid charging. Giving them tax relief on that cost closes a gap that otherwise looks like an unfair benefit.

Where business mileage reimbursement fits

None of this replaces the need to reimburse genuine business mileage correctly. That is a separate calculation, governed by HMRC's Advisory Electricity Rate for company cars, and it needs its own evidence trail. Our Reimburse product is built specifically for that job, so fleets can keep personal charging cost and business mileage reimbursement cleanly separated.

Getting started

• Map where your drivers currently charge: home, work, or mostly public
• Check whether any of that cost currently gets any tax relief
• Decide whether workplace infrastructure and salary sacrifice charging should run together
• Talk to payroll about adding a single new deduction line

More detail on setup is available for HR teams and fleet and procurement teams.
