Excess Mileage Explained

When leasing a car through a Personal Contract Hire (PCH) agreement, you’ll be asked to choose an annual mileage allowance. But what happens if you go over it?

This guide explains how excess mileage charges work, how they’re calculated, and how you can manage or avoid them.

What Is Excess Mileage?

Excess mileage is the additional distance you drive beyond the total mileage limit agreed in your lease contract. If you exceed this limit, you’ll be charged a per‑mile fee at the end of your agreement.

These charges are designed to cover the vehicle’s increased depreciation due to higher mileage.


How Your Mileage Allowance Works

Your mileage limit is calculated over the entire term of the lease, not per year.

Example:

  • 3-year lease at 10,000 miles per year = 30,000 miles total

  • 2-year lease at 8,000 miles per year = 16,000 miles total

Mileage is only checked at the end of the contract when the vehicle is collected.


How Are Excess Mileage Charges Calculated?

Every PCH lease includes an agreed excess mileage rate, typically ranging from 3p to 30p per mile (including VAT). The rate depends on the make/model of the vehicle and the funder.

Example:

  • Contracted total mileage: 30,000 miles

  • Actual mileage: 32,500 miles

  • Excess: 2,500 miles

  • Charge rate: 6p per mile

Total excess mileage charge: 2,500 × £0.06 = £150


Are Excess Mileage Charges Avoidable?

Yes — and they’re easy to manage if you monitor your usage throughout the lease. Here’s how:

Check your odometer every few months. Divide your mileage allowance by the number of months to stay on track.

Think carefully about your lifestyle, commute, holidays, and weekend use. It’s better to build in a small buffer.

Some funders may allow you to increase your mileage allowance during your lease (subject to approval). This may adjust your monthly payments but helps avoid a large end-of-term bill.

If you’re near the end of your term and still using the vehicle, a short extension may reduce the excess mileage gap.


What Happens If I Go Over?

If you exceed your total mileage:

  • You’ll receive a final excess mileage invoice after the vehicle is returned

  • Charges are added to your end-of-lease bill

  • The vehicle must still meet Fair Wear & Tear standards separately from mileage

There are no refunds for unused miles.
