What if your drivers did fewer miles?
−0 miles/yrWhy excess mileage charges catch fleets off guard
Most fleet managers only check mileage when the vehicle comes back at end of contract. By then, the invoice is a fait accompli — no time to adjust driver behaviour, redistribute vehicles, or negotiate with the funder. The charges are baked in.
The compounding effect is what catches people out. An extra 200 miles per month sounds trivial — but multiply that across 50 vehicles over a 36-month contract and the numbers become serious. At 12p per mile, that's £43,200 in excess charges that accumulated gradually and landed as a single bill at lease end.
Mileage pooling — offsetting over-mileage vehicles against under-mileage ones — can reduce the hit significantly. Some funders support it, but most don't make it easy to track. Without a live view of where every vehicle sits against contract, pooling remains a theoretical benefit rather than a practical tool.
Connected vehicle data has changed the equation. Real-time odometer feeds from 15+ manufacturers mean fleet operators can now track mileage continuously, not quarterly. The data exists — the question is whether your systems are set up to use it.
The calculator above gives you a snapshot. Orbis gives you the live picture — continuous mileage tracking, excess charge forecasting, mileage pooling analysis, and automatic alerts when a vehicle trends over contract. Talk to us about mileage management →
What to do about excess mileage
Frequently Asked Questions
What is an excess mileage charge?
An excess mileage charge is a per-mile fee applied when a leased vehicle exceeds its contracted annual mileage allowance. Rates typically range from 6p to 20p per mile depending on the vehicle and funder, and charges are assessed at the end of the contract term.
How are excess mileage charges calculated UK?
Excess mileage charges are calculated by multiplying the number of miles driven over the contracted allowance by the agreed pence-per-mile rate. For example, if you contracted 10,000 miles per year but drove 12,000, and your excess rate is 12p per mile, the charge is 2,000 × £0.12 = £240 per vehicle per year.
How can I avoid excess mileage charges on my fleet?
The most effective way to avoid excess mileage charges is to monitor actual mileage against contracted allowances throughout the lease term, not just at the end. Regular monitoring lets you renegotiate contracts, redistribute mileage across vehicles (mileage pooling), or adjust driver assignments before charges compound. Fleet intelligence platforms like Orbis track this automatically using connected vehicle data.
What is the average excess mileage charge per mile in the UK?
The average excess mileage charge in the UK ranges from 6p to 20p per mile depending on the vehicle type, funder, and contract terms. Premium and electric vehicles typically attract higher rates (12p-20p), while standard fleet vehicles are usually 6p-12p. These charges are set at the start of the contract and apply to every mile over the allowance.
Can you negotiate excess mileage charges at end of lease?
Some funders will negotiate excess mileage charges at end of lease, particularly if the vehicle is in good condition or if you are renewing with them. However, negotiation is much harder after the fact. The most effective approach is to flag excess mileage early in the contract term and request a mileage amendment or contract variation before the lease ends.
