A company car is one of the more generous benefits a UK employer can offer, but it is also one of the trickiest to manage well. Once you hand someone the keys, a long list of questions follows. Who pays for fuel on weekends? What happens if the driver picks up penalty points? Can a spouse drive it? Who sorts out the insurance claim after a car park scrape? A written Company Car Policy is the tool that answers those questions before they become arguments. On this page I walk through what a sensible policy covers, who it should apply to, and the practical points employers tend to overlook. If you would prefer to talk through your situation with someone who has seen plenty of these policies, there is an option further down to book a call with an experienced legal adviser.

What this document is

A Company Car Policy is a workplace document that sets out the rules for allocating, using, and returning vehicles owned or leased by the business. It sits alongside the employment contract and usually forms part of the staff handbook. The policy makes clear that the car remains the property of the company, explains who qualifies for one, and spells out what is expected of the driver day to day.

Typical sections cover eligibility, permitted private use, insurance obligations, driving licence checks, what to do after an accident, servicing and maintenance responsibilities, fuel arrangements, handling of fines and penalty charges, the employer's right to withdraw the vehicle, and what happens when employment ends. Because the car is a benefit in kind, the policy will also flag that tax and National Insurance implications flow from its use.

A clear policy protects the business, reduces disputes, and gives drivers a single point of reference when something goes wrong.

How to use this document

  1. Decide who the policy applies to. Work out which roles genuinely need a company vehicle and which are better suited to a car allowance or mileage reimbursement. Your policy should set out eligibility in plain terms, covering job role, length of service if relevant, and any driving licence requirements. Being explicit here prevents accusations of favouritism later on.
  2. Set the rules for use. Spell out whether the vehicle is for business only or whether private use is permitted, who else is allowed to drive it, and any geographic limits such as travel outside the UK. Cover expectations around cleanliness, smoking, pets, and carrying passengers. These small details cause most of the friction in practice.
  3. Address insurance, licence checks, and accidents. Explain how the vehicle is insured, what the excess position is, and how often driving licences will be checked. Include a clear procedure for reporting accidents, damage, and theft, including timeframes and who to contact. Drivers should know exactly what to do in the moments after a bump.
  4. Cover tax, fuel, fines, and maintenance. Make it clear that a company car is a taxable benefit and that the employee is responsible for any personal tax liability that arises. Set out how fuel is paid for, who handles servicing and MOT, and that parking fines, speeding tickets, and congestion charges incurred by the driver remain their personal responsibility.
  5. Plan for withdrawal and the end of employment. Reserve the right to withdraw the vehicle where the role changes, performance concerns arise, or the driver loses their licence. State that the car must be returned on request and on the last day of employment, in a reasonable condition, with all keys, documents, and accessories. This avoids awkward conversations later.

Common questions

Q Is a company car a taxable benefit in the UK?
Yes. Where a company car is made available for private use, HMRC treats it as a benefit in kind and the employee pays income tax on its taxable value. The employer also pays Class 1A National Insurance. The amount depends on the car's list price, CO2 emissions, and fuel type. Current rates and bands are published on gov.uk, so check there for up to date figures before finalising your policy.
Q Can we stop an employee using the company car for personal trips?
You can, as long as the policy says so clearly and the restriction is applied consistently. Some employers permit private use as part of the overall package, others restrict the vehicle to business journeys only. Whichever approach you take, write it down, make sure the insurance matches the permitted use, and explain the tax consequences to the driver so there are no surprises.
Q Who pays for parking fines and speeding tickets?
As a general rule, the driver is personally responsible for any penalty they incur, including speeding fines, parking tickets, and congestion or clean air zone charges. The policy should say this expressly and explain the process if a charge is sent to the company first. Employers can usually recover the cost from the driver where the policy and employment contract permit deductions from wages.
Q Does the employer have to give a reason to take the car back?
The starting point is that the company owns or leases the vehicle and the driver is using it as a benefit of their role. A well-drafted policy will reserve the employer's right to withdraw the vehicle, for example where the employee loses their licence, moves to a role that does not require a car, or is on long-term absence. Stating this upfront avoids disputes.
Q Can the employee make modifications to the vehicle?
Almost always no, unless the employer agrees in writing. Modifications can void warranties, breach lease terms, affect insurance, and reduce resale value. The policy should require prior written consent for any alteration, including stickers, tow bars, and aftermarket electronics. This protects the business and keeps the fleet in a consistent, sellable condition at the end of the arrangement.
Q What should happen if the driver is involved in an accident?
The policy should set out a step by step reporting procedure: make sure everyone is safe, call the emergency services if needed, exchange details with other parties, take photographs, and report the incident to the employer and insurer within a set timeframe, often 24 hours. Drivers should not admit liability at the scene. Clear instructions here make insurance claims much easier to handle.
Q Does the policy need to cover electric and hybrid vehicles differently?
It is worth adding specific wording where the fleet includes electric or hybrid cars. Cover who pays for home charging, whether a charge point will be installed, how charging on business trips is reimbursed, and what happens to the charger when employment ends. Tax treatment for electric vehicles currently differs from petrol and diesel, so signpost drivers to check gov.uk for the latest rates.
