What is average UK car mileage? And does it matter?

A mileage figure on an ad often triggers more instinct than analysis: low is good, high is bad. The truth is considerably more nuanced, and getting it right is worth real money whether you are buying or selling.

The UK average: about 7,000 miles per year

According to the Department for Transport's National Travel Survey, the average car in England covers roughly 7,000 miles a year. That is lower than before the pandemic, reflecting more working from home and fewer long commutes.

So a typical five-year-old UK car has roughly 35,000 miles on the clock, and a ten-year-old car around 70,000 miles. These are averages, and significant variation either side is perfectly normal.

Averages vary by fuel, use and owner type

The headline number hides big differences between groups of drivers. As general guidance rather than official statistics:

• Company and business cars usually cover well above the average, often double or more, especially cars used by field staff or sales reps.
• Private petrol cars tend to sit close to the national average.
• Diesels often run higher mileages, because people tend to choose diesel when they know they drive a lot.
• EVs are frequently used as daily commuter cars, so their mileage is often at or above average.
• Second cars and low-use households can cover well under half the average.

How mileage affects value

In our UK Used Car Prices Report (October 2026), based on used-car asking prices from large UK online car dealers, every 10,000 extra miles took about 5% off the asking price on top of the effect of age. Cars with unusually low mileage for their age usually command a premium, although buyers may want evidence, such as MOT history, that the reading is genuine.

In our experience the relationship is not perfectly linear (editorial guidance, not a fixed rule):

• A car moderately above the typical mileage for its age usually sees a gentle, steady penalty.
• Once mileage is far above normal for the age, demand from private buyers falls away and the price gap widens.
• At very high mileages, trade and instant-buy services are often the most practical route to sell.

Why super-low mileage is not always good

A ten-year-old car with 15,000 miles on the clock sounds like a bargain. Often it is, but it carries hidden risks:

• Seals and rubbers dry out if unused. Door seals, boot seals, handbrake cables, turbo oil seals, head gasket rubber. On a car that barely moves, these age faster than they wear out.
• Brakes corrode and seize if parked up. A car used for the weekly shop often has severely rusted discs.
• Battery life is short without regular charging runs. Both 12V batteries on conventional cars and HV batteries on EVs age faster when not used.
• Tyres harden and crack with age. A 2016 car with its original tyres at 20,000 miles probably needs them replaced anyway.
• Fluids degrade over time, not just mileage. Brake fluid absorbs moisture. Power steering fluid and coolant have life limits.

A garaged, well-used second car that does 8,000 moderate miles a year, all warm long runs, is often mechanically better than a barely-driven car of the same age that only ever did five-mile school runs on cold engines.

Why high mileage is not always bad

A well-maintained motorway-miles diesel at 150,000 miles is often in better mechanical condition than a 60,000-mile urban petrol. Long warm runs at constant revs are what engines are engineered for. Short cold runs in stop-start traffic are what kills them.

When evaluating a high-mileage car:

• Check the service history for consistent intervals. High mileage with religious servicing is fine; high mileage with skipped services is not.
• Ask about the typical journey profile. Motorway miles on a diesel: good. Short urban petrol miles with heavy use: be cautious.
• Look for evidence of big wear-items already done: clutch, timing belt, brakes, suspension. A 130,000-mile car where these have been replaced recently is effectively low-mileage from a reliability perspective.

Mileage and selling: what to do about it

If your car has high mileage

Lean into it. Be specific in your ad: "Mostly motorway miles, full service history at 10,000-mile intervals, clutch and belt done at 90k, new tyres all round at 105k." Buyers overlook high mileage if the context is reassuring.

Pricing: be realistic. Many buyers filter listings by mileage bands, so pricing and describing the car to sit just below a round-number threshold (say 100,000) can help it appear in more searches. Equally, if your car has genuinely low mileage for its age, advertise that prominently.

If your car has low mileage

Have the paperwork to prove it. A full MOT history with consistent odometer growth is the simplest protection. If you have had work done on items that go off with age (new tyres, fresh brake fluid, battery replaced), mention it, because wary buyers will worry about those things.

Consider a pre-sale service if the car has not had one for a while, even if the manufacturer's interval has not been reached by miles. The service stamp and a clean oil level reassure the kind of buyer who pays top money.

How moValue treats mileage

When you value a car on moValue, we pull the latest MOT odometer reading from DVSA, calculate your annual average, compare it to the UK norm for your car's age, and factor all of that into the valuation. We also flag anomalies like mileage going backwards (a potential clocking indicator) and suspiciously low cumulative mileage for the vehicle's age.

That way you see a mileage-aware valuation rather than a one-size-fits-all number.
