Cheapest Used Cars to Run UK
Buying used can be one of the smartest ways to reduce car costs, but only if you choose the right model and the right individual car.
This guide focuses on cheap used cars to run in the UK, with practical examples, hidden risk warnings and the checks that matter before you buy.
The simple answer
The cheapest used cars to run are usually small, reliable petrol cars, efficient hybrids and common models with affordable parts. A cheap asking price is not enough.
For most used buyers, the safest low-cost choices are cars with good service history, sensible insurance, cheap tyres, simple maintenance and no obvious MOT red flags.

Best cheap used car by driver type
A cheap used car only works if it suits your driving pattern.
Lowest-risk used buy
Toyota Yaris or Honda Jazz, especially with strong service history and sensible mileage.
City and short journeys
Hyundai i10, Kia Picanto, Toyota Aygo, Citroën C1 or Peugeot 108.
Town and mixed commuting
Toyota Yaris Hybrid or Honda Jazz Hybrid can make sense where fuel economy matters.
Need more space
Skoda Fabia for small-family use, or Skoda Octavia if you genuinely need a larger car.
Cheap used cars to run: practical examples
These examples are not a fixed ranking. Condition, service history and insurance quotes matter more than the badge.
Toyota Yaris
The Yaris is one of the strongest used choices because it combines efficiency, reliability reputation and easy day-to-day ownership. Hybrid versions are especially useful for town driving.
Best for: reliability, fuel economy and low-risk ownership.
Watch out: good examples can cost more to buy, so check depreciation and purchase price properly.
Honda Jazz
The Jazz is a sensible used car if you want low running costs with more space than most city cars. It is more of a practical long-term choice than a bargain-bin option.
Best for: practicality, reliability and sensible ownership.
Watch out: it may cost more upfront than smaller used city cars.
Hyundai i10
The i10 works well as a used city car because it is compact, usually economical and easier to live with than larger cars if you mostly drive locally.
Best for: town driving, local mileage and short commutes.
Watch out: check clutch, tyres, service history and whether the size suits your real use.
Kia Picanto
The Picanto is a simple, compact used car that can suit short journeys, first-car buyers and drivers who want manageable fuel, tyre and servicing costs.
Best for: city use, first cars and short commutes.
Watch out: young-driver insurance can still be high, so get a quote before buying.
Toyota Aygo / Citroën C1 / Peugeot 108
These small city cars can be cheap to fuel, park, insure and maintain. They are useful if your driving is mainly local and you do not need much space.
Best for: first-time drivers and low-mileage households.
Watch out: they are less suitable if you regularly carry passengers, luggage or do long motorway trips.
Skoda Fabia
The Fabia is useful if you need more space than a city car but do not want larger-car running costs. Choose engine and trim carefully to keep costs sensible.
Best for: practical small-car use.
Watch out: avoid assuming every engine, gearbox or trim costs the same to own.
Vauxhall Corsa
The Corsa is common on the used market, which gives buyers plenty of choice and makes repairs familiar to many garages. Costs vary a lot by age, engine and condition.
Best for: buyers who want choice and easy parts availability.
Watch out: inspect individual cars carefully and check insurance before committing.
Skoda Octavia
The Octavia is larger than most cheap-to-run cars, but it can make sense if you need space and want to avoid SUV running costs.
Best for: families, luggage space and higher-mileage use.
Watch out: larger tyres, higher servicing costs and diesel suitability need checking.
What makes a used car cheap to run?
A good used buy controls several costs at once, not just the purchase price.
A well-maintained used car is usually safer than a cheaper neglected one.
Get a real quote for the exact car before deciding it is cheap.
Repeated advisories can reveal tyres, brakes, suspension or corrosion risk.
Good MPG matters more for commuters and higher-mileage drivers.
Common tyre sizes and easy-to-source parts help keep repair bills down.
Used cars may have already taken the biggest depreciation hit, but condition still matters.
Cheap used cars: petrol, hybrid, diesel or electric?
The cheapest fuel type depends on mileage, journey type and charging access.
Petrol
Usually safest for low-mileage used buyers, short trips and simple ownership.
Hybrid
Strong for town driving and mixed commuting, especially if fuel use matters.
Diesel
Can still work for high motorway mileage, but avoid for mostly short trips and stop-start local use.
Electric
Can be cheap per mile with home charging, but range, battery health, insurance and charging access matter.
Compare fuel types: Use Petrol vs Hybrid vs Electric: Which Is Cheapest to Run UK? before choosing based on fuel type alone.
Used cars that look cheap but may cost more
A low asking price can hide expensive ownership risk.
Parts, tyres, diagnostics and labour can still be premium-priced.
Fuel, tyres, brakes and insurance can be much higher than a hatchback.
Short local journeys can be a poor match for many diesel cars.
Insurance, wear and previous use can all become bigger risks.
No history means more uncertainty around timing belts, servicing and neglect.
The cheapest advert may be cheap for a reason. Inspect carefully.
What to check before buying
This is where you avoid turning a cheap used car into an expensive mistake.
Before viewing: Open the Used Car Buying Checklist UK and use it alongside the advert and MOT history.
