Fleet insurance

Grey Fleet Insurance

cover for the cars your staff own and drive on company business, and the gap a private policy can leave

Cover for the arrangement where employees drive their own cars on company business. The employee’s policy answers first, provided business use is on it, and the employer usually sits behind that.

  • Staff cars used for work
  • Business use and mileage claims
  • Employer checks and records
  • FCA authorised and regulated

Quick answerA grey fleet is the set of cars your staff own but drive on company business. The employee’s own policy is the first to answer, and it does so only if business use has been added. Employers often sit behind that with their own arrangement, alongside licence checks and a record of who drives. Tell us how your staff drive, and specialist UK fleet brokers can come back with quotes.

Vehicles the company owns? Our fleet insurance page covers those; a grey fleet is the cars your staff own.

The cars you do not own

The Cars You Do Not Own but Still Rely On

A grey fleet is made up of privately owned cars doing company work. Nothing appears on a company schedule, which is exactly why the arrangement is easy to run without noticing it exists.

Employee-owned vehicles

Bought, taxed and insured by the member of staff.

Used for company journeys

Client visits, site calls and deliveries.

Paid by the mile

Or through a car allowance instead of a company car.

Insured privately

On the employee’s own motor policy.

Checked by the employer

Licence, cover and roadworthiness.

Backed by the business

Where the employer arranges cover behind it.

Which policy answers

Where the Employee’s Own Policy Stops and Yours Starts

The personal policy is the one that responds, and only if business use has been added to it. An employer arrangement sits behind that, for the times when it does not answer as expected.

  1. The employee adds business use

    Their insurer records that the car is used for work.

  2. The employer checks it

    Certificate, licence and roadworthiness, at set intervals.

  3. A claim goes to the personal insurer

    It is their policy that responds first.

  4. The employer arrangement sits behind

    For where the personal cover falls short or lapses.

Which policy pays

Which Policy Answers for a Grey Fleet Journey

There is no single grey fleet policy. What matters is the order in which cover responds, and whether each part of it is actually in place on the day of the journey.

Which cover answers on a grey fleet journey
SectionWhere it sitsWhat to know
Injury and damage to othersThe employee’s insurerPaid either way, then recovered if business use was missing
Damage to the employee’s carTheir own comprehensive coverThe employer does not insure it
Business use extensionAdded to the private policyUsually a small change, not automatic
Contingent liabilityArranged by the employerResponds where the personal policy does not
Goods carried for the businessA separate policyMotor cover does not extend to them
Legal expensesEither policy, if addedWorth checking which one holds it
Breakdown assistanceUsually the employee’sSome employers arrange their own

Commuting is not business use. Travel between home and one regular workplace is rated separately, and having it does not mean work journeys are covered.

The gap

The Gap Business Use Leaves Behind

Grey fleet problems are nearly always gaps rather than flat refusals. The cover exists somewhere, but not on the policy anyone assumed, and the cost usually lands on the employee or the employer rather than on the injured party.

Business use never added

The commonest gap of all.

Commuting only

Cover that stops at one regular workplace.

Carrying colleagues for payment

Sharing costs can change the use class.

Goods and equipment carried

Motor cover does not insure the load.

An expired licence or MOT

Where nobody checked at the right time.

A car used far beyond expectations

Mileage well above what was declared.

Ways staff drive

Mileage Claims, Car Allowances and Occasional Errands

Grey fleet driving turns up in several shapes, and the informal ones are the easiest to overlook.

Mileage claims

Reimbursed per mile for business journeys.

Car allowance drivers

Paid instead of being given a company car.

Field and sales staff

On the road most of the working week.

Care and community visits

Short journeys, many of them, every day.

Occasional errands

A trip to the bank, the post or a supplier.

Volunteer drivers

Common in charities and community groups.

Who has one

The Employers Running a Grey Fleet Without Realising It

Any organisation that reimburses mileage has a grey fleet, whether or not it has ever used the phrase.

Care and healthcare providers

Staff visiting clients in their own cars.

Professional firms

Consultants and surveyors travelling to clients.

Sales-led businesses

Field staff on a car allowance.

Charities and community groups

Volunteers using personal vehicles.

Schools and colleges

Staff driving between sites.

Any firm paying mileage

Even for occasional journeys.

A mix of both? See business fleet insurance for the vehicles the company owns.

Own cars or company ones

Employees’ Own Cars vs Vehicles the Business Owns

A grey fleet costs the business less to hold and more to govern. Company vehicles reverse that: more cost, far more control.

Cost

What a Grey Fleet Arrangement Costs an Employer

The number of drivers, the business mileage, the work they do, the checking regime and the cover the employer puts behind it. We do not print average premiums.

Why the mileage leads

Business miles driven is the figure an insurer keeps returning to, because it describes the exposure better than the number of staff does.

Why the checking regime counts

An employer that checks licences and cover on a set cycle presents a very different risk from one that has never asked.

The details

Four Checks Before Staff Drive Their Own Cars

Grey fleet claims turn on what the employer knew and when. Four checks come up again and again.

  1. See the certificate

    Confirm business use is actually on the personal policy.

  2. Check the licence

    Including categories and any endorsements.

  3. Confirm the car is roadworthy

    A current MOT where the age requires one.

  4. Record every check

    Dates and outcomes, kept where they can be found.

Enquiry checklist

The Records an Insurer Expects an Employer to Hold

Six things shape a grey fleet enquiry: the drivers, the mileage, the work, the checks, the records and any incidents.

How many drivers

Staff using their own cars for work.

Business mileage

Annual miles driven on company journeys.

What the work involves

Visits, deliveries or general travel.

The checking regime

How often licences and cover are seen.

The driving policy

What staff are told they may and may not do.

Incidents so far

Anything that happened on a work journey.

Comparing

Comparing Contingent Cover and Occasional Business Use

Four areas decide whether a grey fleet arrangement holds: what the personal policies carry, what the employer adds, the checks, and the conditions attached. The price is only one of them.

The personal policies

  • Business use added
  • Commuting included
  • Any mileage limit

What the employer adds

  • Contingent liability
  • Legal expenses
  • Breakdown assistance

The checks

  • Licence check frequency
  • Certificate sighting
  • MOT confirmation

Conditions

  • Written driving policy
  • Age or licence limits
  • What happens after an incident

Ask to see the certificate, not the promise. Business use is either on the policy or it is not. Unfamiliar terms are explained in our plain English jargon guide.

Cutting costs

Running a Grey Fleet More Cheaply and More Safely

The levers are the checks, the written policy, the mileage, driver training and cutting unnecessary journeys. We publish no savings figures.

Check licences on a cycle

Regular checks improve the terms offered.

Write a driving policy

Staff then know what is expected.

Cut unnecessary journeys

Fewer business miles is the largest lever.

Train the regular drivers

Some insurers recognise it.

Record mileage accurately

Guessed figures cost more than real ones.

Compare with company cars

For heavy mileage, owning can work out better.

FAQs

Grey Fleet Insurance FAQs

Answers on business use, employer responsibility, licence checks and mileage claims.

What is a grey fleet?

It is the set of privately owned cars that staff drive on company business. Nothing sits on a company schedule, which is why plenty of employers run one for years without ever using the phrase.

Does my employee’s own insurance cover work driving?

Only if business use has been added to it. A standard private policy covers social use and often commuting, and neither of those extends to visiting clients or driving between sites during the working day.

Is commuting the same as business use?

No. Commuting is travel between home and one regular workplace, and it is rated separately. A policy with commuting on it does not cover a journey to a client, a supplier or a second site.

Whose policy pays after an accident?

The employee’s own insurer deals with it first. Someone else injured is paid whether or not business use was on the policy, though the insurer can then recover that money from the employee. What is genuinely at risk without business use is the employee’s own car and their standing with the insurer.

Do I have to check my staff’s insurance?

It is not a formal requirement in the way an operator licence is, but employers are generally expected to take reasonable care over staff driving on their behalf, and seeing the certificate is the simplest way to do that.

How often should licences be checked?

Many employers check at least once a year, and more often for staff who drive constantly or who have endorsements. What matters to an insurer is that there is a cycle and that it is recorded.

Does paying mileage create any cover?

No. Reimbursing miles is a payment, not an insurance arrangement. The cover still comes from the employee’s policy, and from whatever the employer has arranged to sit behind it.

What is contingent liability cover?

It is employer cover that responds where an employee’s own policy does not, for example because business use was missing or the policy had lapsed. It does not replace the personal policy, it backs it up.

Are volunteer drivers treated differently?

The principles are the same, though many insurers treat voluntary driving more generously than paid work. Charities still need to confirm that each volunteer’s own policy covers the journeys being asked of them.

Does a car allowance change anything?

Not for the insurance. An allowance is pay rather than a company car, so the vehicle remains the employee’s and their policy still has to carry business use for the journeys they make.

What if an employee carries equipment?

A motor policy insures the vehicle rather than the load. Equipment and stock need separate cover, and heavy or valuable items carried regularly are worth mentioning when the arrangement is set up.

Can staff carry colleagues?

Usually, as long as no payment is made beyond sharing running costs. Charging passengers can move the journey towards hire and reward, which a private policy does not cover.

Is a written driving policy worth having?

Yes. It sets out what staff may drive, what checks apply and what to do after an incident. Insurers ask about it, and it makes the checking cycle much easier to run consistently.

Is a grey fleet cheaper than company cars?

It costs less to hold and more to govern. For heavy business mileage, company vehicles often work out better once allowances, mileage payments and the checking effort are counted together.

What if an employee has an older car?

Age alone is not a problem, though roadworthiness is. Employers usually confirm a current MOT where the car’s age requires one, and some set a maximum age for cars used on company work.

How do I compare grey fleet arrangements?

Look at what the personal policies actually carry, what the employer adds behind them, how often checks happen, whether the mileage figures are real, and what the conditions say after an incident.
