Examples of Cheap Cars to Run in the UK
The cheapest cars to run are usually small, efficient and inexpensive to insure. The right choice depends on whether you need a city car, a commuter car, a family car or an electric vehicle.
Dacia Sandero
The Dacia Sandero is one of the strongest choices for drivers who want low purchase costs and simple running costs. It is not the most luxurious option, but it is practical, affordable and usually cheaper to own than many larger hatchbacks.
Best for: drivers who want a simple low-cost car without paying for unnecessary extras.
Kia Picanto
The Kia Picanto is a strong cheap-to-run city car. It is small, efficient and generally affordable to insure, making it a sensible option for short commutes, town driving and first-time drivers.
Best for: city driving, short commutes and drivers who want low day-to-day costs.
Hyundai i10
The Hyundai i10 is another small car that tends to offer low running costs. It is compact, efficient and practical enough for everyday use, while still being easier to park and cheaper to run than larger cars.
Best for: drivers who want a small petrol car for regular local journeys.
Toyota Yaris Hybrid
The Toyota Yaris Hybrid can be a good option for drivers who want low fuel costs, especially in town or stop-start traffic. It may cost more to buy than some budget petrol cars, but strong fuel economy and Toyota’s reliability reputation can make it attractive long term.
Best for: commuters, city drivers and people covering regular mileage.
Honda Jazz
The Honda Jazz is often chosen by drivers who value practicality and reliability. It may not always be the cheapest car to buy, but its efficient hybrid options and practical interior can make it a strong low-running-cost choice.

Dacia Spring
The Dacia Spring is a low-cost electric car option. For drivers who can charge at home and mainly drive locally, electric running costs can be much lower than petrol. However, range, charging access and purchase price still need to be considered.
Best for: low-mileage drivers with home charging access.
Why Fuel Efficiency Matters
Fuel is one of the most visible running costs for UK drivers.
More efficient vehicles can save hundreds of pounds per year, especially for commuters and high-mileage drivers.
