Mileage allowances are a core part of any vehicle leasing agreement, and funders set these limits to protect the predicted future value of the vehicle. Even with careful planning, business needs can change—perhaps your team is travelling further to reach new clients, or your company has grown faster than expected. When this happens, exceeding your contracted mileage is not unusual.
Below, we provide a clear and comprehensive explanation of what excess mileage charges are, how they are calculated, and how you can minimise or even avoid them.
What happens when you go over mileage on a leased vehicle?
First and foremost, there is no need to panic. Going over your mileage allowance is one of the most common occurrences in vehicle leasing. Funders routinely receive vehicles that have surpassed their contracted mileage, and there is a standardised, transparent process for handling it.
At Commercial Vehicle Contracts, we guide customers through this process every day, ensuring clarity and avoiding unnecessary stress. Before we look at what happens at the end of the agreement, let’s define the charge itself.
What is the excess mileage charge in vehicle leasing?
An excess mileage charge is a fee applied when the total mileage on your vehicle exceeds the limit stated in your leasing contract. When your lease ends, the vehicle is inspected, and part of this inspection includes an odometer reading.
The finance provider will compare the vehicle’s total mileage to your contracted allowance. Any additional miles driven are charged at the agreed excess mileage rate, which is set out clearly in your finance documentation.
How much is the excess mileage charge?
Excess mileage rates vary depending on the funder and the type of vehicle. Charges typically range from 6p per mile up to £1 per mile or more. Higher-value vehicles often incur higher charges due to the increased impact that additional mileage has on their residual value.
Some funders use a tiered structure, such as:
- 6p per mile for mileage up to 10% above the contracted amount, and
- 9p per mile for any mileage beyond that threshold.
Mileage limits are usually expressed as an annual allowance (e.g., 10,000 miles per year), but what ultimately matters is the total mileage when the vehicle is returned.
Where to find excess mileage charges?
Your exact excess mileage charge is stated in your finance agreement.
This should always be reviewed before signing your lease to ensure the allowances and rates reflect your expected usage.
Excess mileage charge calculator
To calculate this charge, you need:
- Your agreed excess mileage rate (from your contract).
- The number of miles driven over your total allowance.
Example:
Mr Andrews leased a Peugeot Partner for 3 years with an annual mileage allowance of 10,000 miles, totalling 30,000 miles for the contract.
At the end of his lease, the vehicle had 35,000 miles.
His excess mileage rate was 6p per mile.
5,000 excess miles × £0.06 = £300 + VAT
This is the total excess mileage charge due.

Businesses that exceed their mileage can offset the resulting charge:
- The excess mileage charge is treated as a service charge, meaning it can be fully offset against corporation tax.
- VAT is also reclaimable:
- 100% reclaimable on commercial vehicles
- 50–100% reclaimable on cars, depending on usage
This makes the charge more manageable for VAT-registered businesses
How to avoid paying the excess mileage charge
While estimating mileage accurately is ideal, business needs can change. Fortunately, many funders allow mileage amendments during the contract, enabling you to increase (or occasionally decrease) your total allowance before the agreement ends.
Monitoring your mileage regularly and acting early is essential. However, mileage amendments are subject to each funder’s own criteria. Common restrictions include:
- No amendments allowed within the first 12 months of the contract
- At least six remaining payments must still be due
- Amendments may not be permitted on Personal Contract Hire (PCH) agreements
- Some providers do not allow changes for Sole Traders or Partnerships with fewer than three partners
- A minimum amendment threshold often applies (e.g., at least a 10% increase from the original mileage)
- An administration fee may be charged for each vehicle amendment
- The account must not be in arrears, in dispute, or under insolvency review
All changes must be authorised by the funder, who has final discretion.
Final Thoughts
Exceeding your mileage allowance is far from a disaster—leasing providers are familiar with this situation, and charges are calculated fairly and transparently. However, the best approach remains careful planning. In many cases, selecting a contract with a slightly higher mileage limit costs significantly less per month than paying excess mileage charges at the end.
