Buying a car is one thing, but owning it is another. A £3,000 used car might look like a bargain, but if it spends half its life in the garage, returns 35mpg, and costs a fortune to insure, it’s not so much of a bargain after all.
When looking for a cheap car, you must consider the total cost of ownership. Purchase price matters, but so do fuel economy, insurance, servicing, tyres, road tax and reliability.
With this in mind, here is my curated list of the top 10 cheapest cars to own in the UK.
I assume that the car is driven 7,500 miles a year (about average for a UK driver), and that we’re looking at a 30-year-old driver with a clean licence and several years of no-claims discount. I also assume 169.7p/litre for petrol, based on the latest RAC average for September 2026. Fuel economy is an estimated real-world figure, rather than the manufacture’s claim.
The cheapest cars come in at around £2,100 – £2,200 a year for fuel, maintenance, tyres and insurance. That’s roughly £175 – £185 a month. And remember, this is for actually running the car – it doesn’t include the purchase price, depreciation, finance (not that you should ever buy a car on finance), or parking.
1. Toyota Aygo 1.0
Typical Autotrader used price: £2,500-£5,000.
Estimated annual running costs: ~£2,160.
- Fuel: £1,033
- Maintenance, servicing and tyres: £475
- Insurance: £650
The Aygo is probably my pick of the bunch (it’s the car my spouse drives). Although, honestly, there isn’t much between the cars on this list – and the choice between them will come down to personal preference. All the cars shown below are winners in my eyes.
The Aygo is tiny, economical and simple, with a well-proven 1.0 litre petrol engine. There are currently plenty of 2016 examples available for £2.5 – 5k.
2. Skoda Citigo 1.0
Typical Autotrader used price: £2,000-£5,000.
Estimated annual running costs: ~£2,150.
- Fuel: £1,052
- Maintenance, servicing and tyres: £500
- Insurance: £650
This is a small, uncomplicated box on wheels. It’s economical, and the car is essentially the same as the Volkswagen up! and SEAT Mii (the main difference is the badge). There are currently 2016 models advertised for as little as £1,990, with plenty of decent examples in the £2 – £5k range.
3. Citroën C1 1.0
Typical used price: £2,000 – £4,500.
Estimated annual running costs: ~£2,200.
- Fuel: £1,071
- Maintenance, servicing and tyres: £475
- Insurance: £650
The C1 is another version of the Aygo formula, sharing its underlying architecture with the Toyota and also the Peugeot 108.
4. Kia Picanto 1.0
Typical used price: £2,500 – £5,000.
Estimated annual running costs: ~£2,330.
- Fuel: £1,181
- Maintenance, servicing and tyres: £500
- Insurance: £650
The Kia Picanto is another excellent little car. It’s small, economical and practical, while five doors make it more useful than some of the tiny three-door alternatives.
5. Suzuki Swift 1.2
Typical used price: £2,500 – £5,500.
Estimated annual running costs: ~ £2,340.
- Fuel: £1,113
- Maintenance, servicing and tyres: £525
- Insurance: £700
The swift is slightly bigger, more practical and its 1.2 litre petrol engine offers respectable fuel economy without being complicated – while Suzuki has a good reputation for reliability. If you want cheap motoring without a tiny city car, this should be near the top of your list.
6. Toyota Yaris 1.0
Typical used price: £4,000 – £7,000.
Estimated annual running costs: ~£2,390
- Fuel: £1,092
- Maintenance, servicing and tyres: £550
- Insurance: £750
The Yaris costs more to buy than an Aygo, but you’re getting a larger and more practical car. It is also a car that has earned a reputation for simply keeping going. If you’re doing a mixture of town and longer-distance driving, I’d seriously consider this over the smaller city cars.
7. Dacia Sandero 1.0
Typical used price: £2,000 – £5,000.
Estimated annual running costs: ~£2,480.
- Fuel: £1,258
- Maintenance, servicing and tyres: £525
- Insurance: £700
Dacia don’t give customers things they don’t need. They build straightforward vehicles that will get you from A to B, and sell them cheaply. The Sandero makes a lot of sense if your priority is getting as much usable car as possible for your money. It’s also the largest car on this list.
8. Hyundai i10 1.0
Typical used price: £2,500 – £5,000.
Estimated annual running costs: ~£2,380.
- Fuel: £1,231
- Maintenance, servicing and tyres: £500
- Insurance: £650
The slightly higher fuel consumption compared with the Aygo and Citigo means it isn’t quite as cheap to run on our assumptions, but the difference is relatively small. For someone wanting a straightforward, inexpensive runabout, it’s difficult to fault.
9. Honda Jazz 1.3
Typical used price: £4,000 – £7,000.
Estimated annual running costs: ~£2,415.
- Fuel: £1,315
- Maintenance, servicing & tyres: £550
- Insurance: £750
This car is probably the most practical on the list. It has an enormous amount of interior space for its size, and Honda has built a strong reputation for reliability over the years.
The downside is that it’s 1.3 litre petrol engine isn’t as economical as the 1.0 litre engines on this list, but if you need to carry people and luggage while keeping running costs under control, the Jazz is a very sensible choice.
The cheapest car is the one you don’t need to replace
This is the most important point of the whole article. Don’t get obsessed with finding the absolute cheapest car to buy. I’d much rather buy a boring, well-maintained petrol car with a comprehensive service history than chase the lowest possible purchase price.
And I’d keep a separate emergency fund for repairs, because even the most reliable 10-year-old car will eventually need some expensive maintenance.
If you do all this, you’ll be making motoring as frugal as it can possibly be in the UK in 2026.
