Van lease mileage explained
Updated September 2026 · 7 min read
Your lease is priced against an agreed annual mileage. Go over the contract total and you pay a pence-per-mile excess charge on the difference at the end. Buying the miles upfront is almost always cheaper than paying excess later.
How the mileage allowance actually works
You agree an annual mileage at the start — 8,000, 10,000, 12,000, 20,000, 30,000 and upwards are all normal on commercial vehicles. That figure is multiplied by the term to give a contract total: 20,000 miles a year over 48 months is 80,000 miles. The total is what matters, not any individual year, so a heavy spring and a quiet autumn even out. The allowance is written into the agreement alongside the pence-per-mile excess rate, so both numbers are fixed and visible before you sign — there is no surprise about the rate, only about how many miles the business ends up doing. We set out the annual mileage, the contract total and the excess rate on your quote, and confirm them in writing.
Why mileage moves the price at all
Because contract hire is priced against what the vehicle will be worth when it comes back. A van returned at 40,000 miles is worth materially more than the same van returned at 120,000 miles, so the lessor recovers more of its cost on resale and can charge you less to use it. Mileage is therefore not an administrative detail — it is one of the four biggest levers on the rental, alongside the vehicle, the term and the initial rental. It also interacts with the term: a 36-month contract at 25,000 miles a year and a 48-month contract at 18,750 both land at 75,000 miles, but they price differently because vehicle age and mileage affect resale value in different ways. Ask us to quote both. More on the mechanics in business contract hire explained.
What does excess mileage cost?
Excess mileage is charged as a fixed pence-per-mile rate for every mile over the contract total, set out in your agreement at the start. It is calculated once, at the end, when the actual odometer reading is confirmed at collection, and it is normally subject to VAT like any other charge. The rate varies by vehicle: it broadly tracks how much value each extra mile removes, so it is lower on a hard-wearing panel van than on a premium car. There is no rebate hidden in the arithmetic — the charge applies to the whole overage, not just the amount past some tolerance. The practical implication is simple: because the rate is known upfront, excess mileage is one of the few end-of-contract costs you can forecast precisely at any point in the term.
Why under-declaring costs more than over-declaring
This is the single most useful thing in this guide. Buying mileage upfront is almost always cheaper per mile than paying excess at the end. When you build miles into the contract, the lessor prices them into a forty-eight-month rental with certainty; when you exceed the allowance, the excess rate reflects the unplanned loss of resale value. So a business that under-declares to shave a few pounds off the monthly figure typically pays more overall, and pays it in one lump at exactly the moment it is also funding the replacement vehicle. Over-declaring is not free either — you pay a slightly higher monthly for headroom you may not use, and unused miles are not normally refunded. But the downside of over-declaring is small and spread; the downside of under-declaring is large and concentrated. If you are genuinely unsure, round up.
How to estimate your mileage honestly
Build it from the round, not from a hunch. Start with the fixed pattern: daily round trip to the first job or depot, multiplied by days worked per week, multiplied by about 46 working weeks. Add the variable work: average job-to-job miles per day, collections from merchants, tip runs, and any regular long trip. Add the depot returns and the fuel stops people forget. Then add a contingency — 10% is a sensible starting point for most trades — for the contract you have not won yet. If you already run telematics, a fuel card or tracker data, use last year's real total and adjust for growth. If you are replacing an existing van, the cleanest input of all is its current odometer reading divided by the years you have had it. Two minutes with real numbers beats a guess you pay for later.
What if your mileage changes mid-contract?
Work changes. You win a contract on the other side of the county, or you lose one and the van sits. Tell us early. A mid-term mileage amendment is often possible: the annual figure is adjusted and the rental re-rated for the remainder, which spreads the additional cost over the months you have left rather than dropping it on you as a single charge at collection. It is not automatic and it is not always available, but it is nearly always better than saying nothing. The one thing that never helps is discovering the overage at hand-back. Set a simple habit instead: check the odometer against your pro-rata contract total every quarter — at 18 months into a 48-month, 80,000-mile contract you should be around 30,000 miles. If you are 8,000 miles ahead, act then.
Mileage across a fleet: pooling and averaging
Where you run several vehicles, each agreement carries its own mileage allowance and its own excess exposure, so a low-mileage van cannot subsidise a high-mileage one unless a pooling arrangement is agreed. Two things help. First, rotate vehicles between rounds where the work allows it, so mileage accumulates more evenly than the rounds themselves do — this is free, and it is the most under-used lever in small fleets. Second, specify by role rather than by convention: the trunking van and the local multi-drop van should not carry the same allowance simply because they were ordered at the same time. If you would like mileage looked at across a group of vehicles rather than one at a time, say so when you enquire and we will quote it that way.
Do you get anything back for unused miles?
Usually not, and it is fairer to say so plainly than to imply otherwise. The allowance is capacity you have bought and the rental is priced on it, so coming in under does not normally generate a refund. Some agreements include a downward adjustment or a credit against unused mileage; if that matters to you, ask before you sign and we will tell you exactly what your agreement does. This is the honest counterweight to "round up if unsure": round up sensibly, not wildly. The target is a realistic figure with a modest contingency — not a defensive over-buy that costs you every month for four years. Get the estimate right and the mileage clause becomes what it should be: a number you agreed once and never think about again. Tell us your real mileage and we will quote to it.
Put a price on it
Tell us the vehicle, the term and the annual mileage you need and we come back with a written quote — usually the same working day. Rentals are quoted ex VAT with the VAT-inclusive figure alongside, and your agreement is with FleetMe.
Thanks — your enquiry is in.
We’ll go through what you need and come back with a written quote, usually the same working day. Your agreement would be with FleetMe — we supply the vehicle, and we confirm it in writing before anything is agreed.
What happens next
- 1 We read what you sent us. We check the vehicle, the length and the mileage you asked for, and work out what we can do at that specification.
- 2 We come back with a written quote. Usually the same working day. It sets out the vehicle, how long you have it, the mileage, the initial rental and the monthly figure — ex VAT with the VAT-inclusive figure alongside.
- 3 You decide. Nothing is committed until you have that in writing and you are happy to go ahead. If we can’t help, we’ll tell you honestly and say why.
Nothing is committed at this stage, and if we can’t help we’ll tell you honestly rather than leave you waiting.

What happens if I go over my van lease mileage?
You pay an excess mileage charge — a fixed pence-per-mile rate written into your agreement at the start — on every mile over the contract total. It is calculated once, at collection, when the actual odometer reading is confirmed, and it is normally subject to VAT.
Is it cheaper to add mileage upfront or pay excess later?
Almost always cheaper upfront. Miles built into the contract are priced with certainty over the whole term, whereas the excess rate reflects unplanned loss of resale value. Under-declaring to reduce the monthly figure usually costs more overall, and lands as a lump sum at the end.
How do I estimate my annual van mileage?
Build it from the round: daily round trip times days worked times about 46 weeks, plus job-to-job miles, merchant collections and tip runs, plus roughly 10% contingency. If you have telematics, a fuel card or an existing van’s odometer reading, use the real figure and adjust for growth.
Can I change the mileage allowance during the contract?
Often yes. A mid-term amendment can adjust the annual figure and re-rate the rental for the remaining months, spreading the cost rather than leaving it as a single charge at collection. It is not automatic, so tell us as soon as you can see you will go over.
Do I get a refund if I drive fewer miles than agreed?
Usually not — the allowance is capacity you have bought and the rental is priced on it. Some agreements include a downward adjustment or credit for unused mileage; ask before you sign and we will tell you exactly what your agreement provides.
Does the mileage allowance apply per year or across the whole contract?
Across the whole contract. The annual figure is multiplied by the term to give a contract total, so a busy year and a quiet year balance out. What matters at collection is the total odometer reading against that contract total.
