Grey Fleet Compliance: What Employers Are Actually Responsible For
'Grey fleet' — employees using their own vehicles for work journeys — is one of the most commonly missed compliance categories, precisely because none of the vehicles are owned or leased by the business. That makes it easy to assume it's the employee's problem alone. It isn't.
What counts as grey fleet
Any employee-owned vehicle used for work purposes: client visits, site-to-site travel, deliveries. Ordinary commuting to a fixed workplace generally sits outside grey fleet obligations — it's journeys made as part of the job itself that bring a vehicle into scope.
What the employer is actually responsible for
As the employer, you have a duty of care to ensure any vehicle used for work is roadworthy and properly insured for business use. In practice that means having visibility of the driver's MOT status, confirming the vehicle is taxed, and specifically checking their insurance policy covers business use — many personal policies explicitly exclude it, which most employees don't realise until a claim is refused.
Why 'business use insurance' is the sharpest edge
A personal car insurance policy without a business-use extension can mean a claim is void following a work-related incident, leaving both the employee and, potentially, the employer exposed. Confirming this isn't a one-off check — it needs revisiting whenever a driver renews their policy.
Not in FleetCompliance yet
This isn't in FleetCompliance today — grey fleet tracking (employee vehicle reg, MOT, tax and business-use insurance confirmation) is on the roadmap. Right now FleetCompliance tracks owned and leased vehicles and machinery, not grey fleet.
Frequently asked questions
Is an employer legally responsible for an employee's own car used for work?
Yes, in terms of duty of care — as the employer you're expected to have reasonable assurance the vehicle is roadworthy (valid MOT, taxed) and insured for business use whenever it's used for work journeys, even though you don't own it.
Does standard car insurance cover business use?
Often not — many personal policies only cover commuting, or exclude business use entirely. It needs an explicit business-use extension, or a specific business policy, and it's the kind of thing that needs re-confirming at each renewal, not checked once and forgotten.
Does grey fleet include commuting to a normal workplace?
Generally no — ordinary commuting to a fixed base is usually outside grey fleet scope. It's journeys made as part of the job itself — site visits, deliveries, travel between locations — that bring a vehicle into scope.
