What is the average annual mileage in the UK?

The best official figure available is for England, where the average car covered 7,100 miles in 2024. That comes from the Department for Transport's National Travel Survey, table NTS0901. It has been falling steadily — the same figure was around 9,200 miles in 2002 — and it varies a lot depending on what you drive.

All cars7,100

Source: DfT National Travel Survey table NTS0901, published 27 August 2025, as summarised by the RAC Foundation. The National Travel Survey covers England, so there is no directly equivalent UK-wide figure — treat 7,100 as the best available yardstick rather than a UK statistic.

Two things are worth knowing about that average. First, it is per car, not per driver: households run more cars between them than they used to, so each one does fewer miles. Second, DfT's own figures show average distance travelled per person has also gradually declined since the early 2000s — 6,082 miles across all modes in 2024. Both effects push the per-car number down.

Diesel and electric cars sit well above the average largely because they tend to be chosen by higher-mileage drivers, not because of anything about the cars themselves. If you drive an EV and cover 12,000 miles a year, you're normal. If you drive a petrol runaround 4,000 miles a year, you're also normal.

What your insurer actually does with the number

Annual mileage is one of the questions every mainstream UK motor insurer asks, and it is genuinely used to price the policy — more miles means more time exposed to risk. What it is not is a lever you can pull to make the quote cheaper. MoneyHelper, the government-backed money guidance service, puts it carefully: “The lower your annual mileage, the lower your premium might be. But this isn't always the case.” Mileage sits alongside your postcode, age, car, claims history and a dozen other factors, and shaving a couple of thousand miles off your estimate is not a dependable saving.

It is, however, a dependable way to get caught short at claim time.

Getting it wrong is a legal thing, not a paperwork thing

When you answer an insurer's questions you're making a representation, governed by the Consumer Insurance (Disclosure and Representations) Act 2012. The Act asks one thing of you: that you take reasonable care not to misrepresent the facts. If your mileage answer turns out to be wrong, what happens next depends on which side of that line you fall — and on what the insurer would have done with the true figure.

  • Careless — an answer given without enough care. There are three possible outcomes. If the insurer would have charged more, it can, in the Act's words, “reduce proportionately the amount to be paid on a claim”. If it would have applied different terms, the policy is treated as if those terms had been in it all along. And if it would not have covered you at all, it can cancel the policy and refuse the claim — though it must then return your premiums.
  • Deliberate or reckless — the insurer “may avoid the contract and refuse all claims, and need not return any of the premiums paid, except to the extent (if any) that it would be unfair to the consumer to retain them”. In practice: no cover, and usually no refund.

The same principle appears in the ABI's own code of practice on misrepresentation, which says that where a misrepresentation is careless, “an insurer must apply a proportionate remedy”. That code covers protection products — life, critical illness and income protection — rather than motor, but it reflects the statutory position the whole industry works to.

What that looks like in practice. In a Financial Ombudsman Service decision published in late 2024, a driver had declared 5,000 miles a year. After an accident, the insurer compared the car's last MOT reading with the odometer and found around 6,500 miles covered in six months — roughly 13,000 a year.

The insurer worked out the customer had paid 73% of the premium the correct mileage would have attracted, and paid 73% of the claim. The ombudsman found that mileage adjustment fair. An understatement of about 8,000 miles cost that driver roughly a quarter of their payout.

That case concerned a commercial policy and was decided under the Insurance Act 2015 rather than CIDRA — but as the ombudsman noted in the decision, the expectations and remedies under the two are broadly similar.

They can check, and the data is public

There is a widespread assumption that nobody ever looks. The DVSA has published MOT history — including the odometer reading recorded at each test — as open data since 2018, and named car insurance companies among the users of that data. Anyone, including you, can look up a vehicle's MOT history free on GOV.UK. Ombudsman decisions show insurers pulling exactly those readings when a claim lands, and comparing them against what was declared.

What mileage should I put on my car insurance?

A good-faith estimate, rounded up rather than down. The asymmetry is the whole point: rounding up costs you a little premium, rounding down can cost you a chunk of a claim. That's why this calculator suggests a figure rounded up to the nearest 1,000 rather than handing you a falsely precise number.

And if your driving genuinely changes mid-policy — a new job, a longer commute — it's worth telling your insurer. Many policies include a term asking you to report changes like that, and it's a five-minute call. Reassuringly, honesty is a defence: in another ombudsman case a driver who had reasonably estimated their mileage, then blew past it because of unforeseen work travel and a family bereavement, was found to have taken reasonable care, and the insurer's proportionate reduction was overturned. Careless guessing is the problem. An honest estimate overtaken by life is not.

What the number means if you lease or have a PCP

If your car is on a personal lease (PCH) or a PCP, your annual mileage isn't just a premium input — it's a direct bill at the end of the contract. Allowances are typically sold in tiers: the BVRLA, the trade body for the UK leasing industry, says the most common contracts are for 8,000, 10,000, 12,000 and 15,000 miles a year. Go over the total across the contract and you pay an excess mileage charge per mile.

Published UK excess rates typically run from around 3p to 30p a mile, and premium or performance cars can go well above that — published examples over 50p exist. Close Brothers Motor Finance publishes 10p per mile plus VAT on its PCP agreements. Santander Consumer works an example at 14.90p per mile excluding VAT, and notes the rate may increase once you're more than 5,000 miles over. Several large funders publish nothing at all and simply point you at your agreement — which is where your real number lives.

Three things about excess mileage that catch people out:

  • It's usually a total, not an annual test. On most UK leases your mileage is assessed once, at the end, against the allowance for the whole contract, so a heavy first year followed by a quiet second year evens out. Some agreements — and some large fleet schemes — work differently, so check yours.
  • Handing it back early changes that. The BVRLA says that if you end a PCP or hire purchase agreement early, excess mileage is worked out pro rata for the time you had the vehicle. Lease agreements commonly work the same way — so an early return can turn a comfortable position into a charge overnight.
  • VAT is a 20% swing. Some agreements quote the pence-per-mile rate including VAT, others plus VAT. The calculator above has a toggle for exactly this, because getting it wrong makes a £600 estimate a £720 bill.

And it runs the other way too: there are normally no refunds for miles you didn't use. Buying a 15,000-mile allowance you never touch is money handed over for nothing. The right allowance is the honest one — which is the same answer as the insurance question, for the same reason.

How this calculator works out the number

No black box. Four lines of arithmetic, all visible:

  • Commute — days a week × round trip × 46 weeks. Not 52: almost all UK workers are entitled to 5.6 weeks' paid holiday a year, which leaves 46.4 working weeks, and we round to 46 to keep the commute figure conservative.
  • Local driving — weekly miles × 52.
  • Longer trips — monthly miles × 12.
  • Holidays and one-offs — number of trips × round trip.

Those four add up to your estimated annual mileage, which we show rounded to the nearest 100 — and then separately suggest a figure rounded up to the nearest 1,000, because rounding up is the direction that protects you on an insurance form.

If you fill in the optional sanity check, we divide the miles you've added by the months you've had the car and annualise it. That real-world figure beats any estimate on this page, and if the two disagree badly, trust the odometer.

The fuel estimate converts your miles to gallons using the MPG you set, converts gallons to litres at 4.546, and multiplies by the pence-per-litre you set. It covers fuel only — not insurance, tax, servicing, tyres or depreciation.

The optional commute lookup on step one is the only part of this page that talks to anything outside your browser. It uses Apple Maps (MapKit JS) to turn the two addresses you type into a real driving route, then doubles the one-way distance for the round trip and fills it in for you. It's the same mapping data the MileMind app itself uses. You can always overwrite the figure it produces — it's a starting point, not a verdict, and a route you actually drive may differ from the one Apple picks.

Work it out on paper

No calculator needed if you'd rather not. Add up a typical week's driving — commute plus everything else — multiply by 52, then add your long trips for the year on top. Round the answer up to the nearest 1,000.

Common questions

What is the average annual mileage in the UK?+
The best available official figure is for England: the average car covered around 7,100 miles in 2024, according to the Department for Transport's National Travel Survey (table NTS0901). It varies by fuel type — petrol cars averaged about 6,200 miles, hybrids 8,000, diesels 8,300 and battery-electric cars 8,900. The average has been falling since 2002, when it was around 9,200 miles.
What mileage should I put on my car insurance?+
A good-faith estimate of what you will actually drive, based on your real commute and travel — rounded up rather than down. Rounding up costs you a little premium; rounding down can cost you part of a claim. Insurers ask you to take reasonable care with the answer, not to be precise to the mile.
What happens if I underestimate my annual mileage on my car insurance?+
If you gave the figure without taking reasonable care, that is a misrepresentation under the Consumer Insurance (Disclosure and Representations) Act 2012. What follows depends on what the insurer would have done with the true figure: if it would have charged more it can reduce your claim proportionately, if it would have applied different terms those terms apply instead, and if it would not have covered you at all it can cancel the policy and refuse the claim — though it must then refund your premiums. If the insurer can show the answer was deliberate or reckless, it can void the policy, refuse the claim and normally keep the premiums. An honest, reasonable estimate that life later overtakes is not a misrepresentation.
Can insurers check my real mileage?+
Yes. Odometer readings recorded at each MOT are published as open data by the DVSA, and anyone can look up a vehicle's MOT history free on GOV.UK. Financial Ombudsman Service decisions show insurers pulling those readings and comparing them with the mileage a customer declared when a claim is made.
Should I round my annual mileage up or down?+
Up. Insurers ask for a good-faith estimate, and the risk sits overwhelmingly on the low side — understating can cost you at claim time, while a slightly generous figure only costs you a little premium. Rounding to the nearest 1,000 miles above your estimate is a sensible habit. Don't inflate it wildly either: the figure should still be one you can defend.
Does lower mileage always mean cheaper car insurance?+
No. MoneyHelper puts it plainly: “The lower your annual mileage, the lower your premium might be. But this isn't always the case.” Mileage is only one of many rating factors, so shaving miles off your estimate is not a reliable way to save money — and it can be an expensive mistake if you ever claim.
How much is excess mileage on a lease or PCP?+
It varies by provider and vehicle, and your own agreement is what counts. Published UK rates typically run from around 3p to 30p a mile, and premium or performance cars can go well above that. Close Brothers Motor Finance, for example, publishes 10p per mile plus VAT on its PCP agreements; Santander Consumer works an example at 14.90p per mile excluding VAT. Check whether your agreement quotes the rate including or excluding VAT — that alone is a 20% difference.
Is lease mileage checked every year?+
Usually not. On most UK leases your mileage is assessed once, at the end, against the total allowance for the whole contract — so a heavy year followed by a quiet one evens out. Some agreements work differently, and if you hand the car back early the BVRLA notes that excess mileage is worked out pro rata for the time you had the vehicle. Your contract is the authority.
Is this calculator free, and what happens to my answers?+
It's completely free, with no sign-up and no email required. All the maths runs in your browser — we never see or store the figures you type in. There is one exception, and it only happens if you use it: the optional commute address lookup sends what you type in those two boxes to Apple Maps, to find the address and measure the driving route. We don't store either address. If you accept analytics cookies, we record the final estimated annual figure so we can tell the tool is being used. If you use the copy-link button, your answers are encoded into the link itself so you can reopen or share the result.
