Almost every small business has a grey fleet, even the ones who would say they have no fleet at all. Grey fleet means employee-owned vehicles used for work journeys: the sales rep in their own car, the manager driving to a supplier, the technician who takes their own van to a job because the company van is booked out.

It is usually the least documented part of a fleet, and it carries real exposure, because the employer's duties do not disappear simply because the vehicle is owned by someone else.

What counts as a work journey

The ordinary commute between home and a fixed place of work is generally not treated as a work journey. Driving between sites, to a customer, to a supplier, to a meeting or to collect materials is. If the journey is made for the business, it is work driving, whatever the logbook on the car says.

Why the duty follows the work, not the vehicle

Under the Safety, Health and Welfare at Work Act 2005, an employer has a duty to ensure the safety, health and welfare of employees at work, and driving for work is covered by that duty. The Health and Safety Authority and the Road Safety Authority publish joint guidance on managing driving for work, which treats work-related road risk as an occupational risk to be assessed and managed like any other.

In practice that means you are expected to know that the person driving on your behalf is licensed to do it and that the vehicle they are driving is legal and roadworthy. Not knowing is not a defence, and after an incident it is the question you will be asked first.

The four checks on every grey fleet vehicle

Driving licence: current, correct category, and physically verified rather than taken on trust. Check the expiry date and record when you checked
Insurance covering business use: this is the one that most often fails, see below
NCT: valid and in date for any car over the relevant age. A private car needs an NCT, not a CVRT
Motor tax: current, and taxed for the correct class of use

Business use cover is the item that catches people out

A standard private motor policy is often written for social, domestic and pleasure use, and commuting to a single place of work. Driving to customer sites, between locations or carrying work equipment can fall outside that, which means an employee doing exactly what you asked them to do may be uninsured while doing it.

What you want to see is a policy that explicitly includes business use. Ask for the certificate or the schedule, check the permitted use wording rather than the customer's summary of it, and note the renewal date so you can ask again next year. If an employee carries goods or equipment for the business, say so when they check with their insurer, because that can change the cover required.

Roadworthiness is still your problem

A valid NCT is a snapshot from up to two years ago. For a car doing high business mileage, that is a long time. You cannot service someone else's car, but you can set a reasonable expectation: tyres within legal tread, lights working, no outstanding advisory items, and a service history that is actually kept up. A short driver declaration covering these, renewed annually, is a proportionate control for a small business.

Mileage reimbursement, done properly

Most Irish employers reimburse business mileage using the civil service motor travel rates, which Revenue permits to be paid without a taxable benefit arising, subject to the conditions and record-keeping requirements of the scheme. The rates vary by engine size and by cumulative annual business mileage band, and they are revised from time to time, so take the current figures from Revenue rather than from a template someone made a few years ago.

Whatever rate you use, you need records: date, journey, purpose and distance. Reimbursing round numbers with no underlying detail is the fastest way to turn a compliant expense into a payroll problem.

A workable grey fleet policy for a small business

Write it down. One page covering who may drive for work, what insurance and documentation is required, and what has to be produced before a work journey is made
Verify documents before the first work journey, then re-check annually and at each insurance renewal
Record the check: what you saw, when you saw it, and the expiry dates on it
Diary the expiry dates so the next check is triggered by the calendar rather than by memory
Get a signed driver declaration covering roadworthiness, penalty points and any medical condition affecting fitness to drive
Include grey fleet journeys in your safety risk assessment alongside company vehicles

Why grey fleet is riskier than your own vans

With a company van, you control the vehicle, the maintenance and the documentation. With grey fleet you control none of it, and you carry a duty for the journey anyway. That inversion is why grey fleet mileage is often the highest-risk driving a small business does, and the least examined.

Tracking grey fleet in FleetMain

You can manage grey fleet in FleetMain the same way you manage company vehicles. Add the employee's vehicle with its NCT, motor tax and insurance expiry dates and a category label such as Grey Fleet so it is easy to filter, and get the same email alerts at 30, 14 and 7 days before anything lapses. On the Business and Fleet Pro plans, the driver roster holds each driver's licence expiry, and the assignment log records who was driving which vehicle and when, which matters just as much when the vehicle is personally owned.
