Best ULEZ-Compliant Used Cars Under £10,000 in the UK

With 12 active Clean Air Zones across the UK, buying a compliant used car is no longer a nice-to-have — it is a financial necessity for millions of drivers. The good news is that you do not need to spend a fortune. There are excellent ULEZ-compliant used cars available for well under £10,000.

Every car on this list meets Euro 6 petrol standards, which means it passes every single Clean Air Zone in the UK — London ULEZ, Birmingham, Bristol, Bath, Bradford, Sheffield, Tyneside, Oxford, Edinburgh, Glasgow, and Aberdeen. No daily charges. No penalties. No stress.

We have ranked them by a combination of purchase price, fuel economy, insurance costs, and reliability. All prices reflect typical asking prices for used examples in good condition as of early 2026.

1. Ford Fiesta 1.0 EcoBoost (2017+)

The Ford Fiesta has been the UK’s best-selling car for decades, and the 1.0 EcoBoost engine is one of the finest small petrols ever made. The three-cylinder turbo is punchy, smooth, and remarkably economical for its performance.

• Typical price: £7,000–£9,500
• Fuel economy: 50–58 MPG (combined)
• Insurance group: 10–16
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

With Ford having discontinued the Fiesta, used examples are in high demand. Expect to pay more for low-mileage examples with full service history, but even higher-mileage cars are reliable if maintained.

2. Volkswagen Polo 1.0 TSI (2018+)

The sixth-generation Polo feels like a small Golf. Build quality is a step above most rivals, the cabin is well laid out, and the 1.0 TSI engine is refined and economical. Available in 95PS and 115PS versions.

• Typical price: £8,000–£9,800
• Fuel economy: 48–55 MPG (combined)
• Insurance group: 8–14
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Polo holds its value well, so you may need to look at higher-mileage examples to stay under £10,000. This is no bad thing — the 1.0 TSI is a durable engine when serviced on schedule.

3. Toyota Yaris Hybrid (2015+)

The Toyota Yaris Hybrid is the standout choice for city driving. The petrol-electric hybrid powertrain is brilliant in traffic, achieving genuinely impressive fuel economy without any need to plug in. Toyota’s reliability reputation means running costs are minimal.

• Typical price: £7,500–£9,500
• Fuel economy: 60–70 MPG (urban)
• Insurance group: 9–13
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

If you do most of your driving in town, the Yaris Hybrid is hard to beat. The self-charging hybrid system means there is no range anxiety and no need for a charging point. In urban driving, it can run on electric power alone at low speeds.

4. Skoda Octavia 1.0 TSI (2017+)

If you need more space without spending more money, the Skoda Octavia is the answer. It has the boot space of a car two classes above, a comfortable ride, and the same VW Group 1.0 TSI engine found in the Polo and Ibiza.

• Typical price: £8,000–£9,800
• Fuel economy: 48–55 MPG (combined)
• Insurance group: 11–15
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Octavia is the best-value family car on this list. The estate version offers van-like boot space at hatchback prices. Just make sure you are looking at the 1.0 TSI petrol and not the older diesel variants.

5. Kia Rio 1.0 T-GDi (2017+)

The Kia Rio comes with one of the best warranties in the business — seven years from new. Buy a 2019 example and you still have factory warranty coverage until 2026. The 1.0 T-GDi turbocharged petrol is smooth and economical.

• Typical price: £6,500–£8,500
• Fuel economy: 50–56 MPG (combined)
• Insurance group: 8–12
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Rio is often overlooked in favour of the Fiesta and Polo, which means used examples are typically cheaper. The warranty adds real peace of mind, especially for buyers who want to minimise unexpected repair costs.

6. Hyundai i10 1.0 (2017+)

The smallest car on this list, the Hyundai i10 is a genuine city car that is cheap to buy, cheap to insure, and cheap to run. It is not designed for long motorway trips, but for urban driving and short commutes it is superb.

• Typical price: £5,500–£7,500
• Fuel economy: 52–58 MPG (combined)
• Insurance group: 3–6
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

Insurance group 3 makes the i10 one of the cheapest cars to insure in the UK — ideal for younger or newly qualified drivers who face high premiums. Hyundai’s five-year warranty also provides good coverage on newer examples.

7. SEAT Ibiza 1.0 TSI (2017+)

The SEAT Ibiza shares its platform and engine with the VW Polo but costs less. You get VW Group engineering at a lower price point, with slightly sportier styling and a well-equipped cabin.

• Typical price: £7,000–£9,000
• Fuel economy: 48–55 MPG (combined)
• Insurance group: 7–13
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Ibiza is the sweet spot between the compact Polo and the more expensive Golf. The FR trim level adds sportier looks and equipment, though insurance costs rise slightly with the more powerful 115PS engine.

8. Mazda 2 1.5 (2015+)

The Mazda 2 is the driver’s choice on this list. The naturally aspirated 1.5-litre petrol is not turbocharged like the others, but it is responsive and enjoyable to drive. Build quality is excellent and Mazda’s reliability record is strong.

• Typical price: £6,000–£8,500
• Fuel economy: 50–56 MPG (combined)
• Insurance group: 8–12
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Mazda 2 is slightly less common than the Fiesta or Polo, which means fewer appear on the used market. When you find a good one, it is worth moving quickly.

9. Suzuki Swift 1.0 Boosterjet (2017+)

The Suzuki Swift is one of the lightest cars in its class, which means the 1.0 turbocharged Boosterjet engine feels quicker than its power figure suggests. It is also genuinely fun to drive on twisty roads.

• Typical price: £6,500–£8,500
• Fuel economy: 50–56 MPG (combined)
• Insurance group: 8–11
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Swift Sport version is also available under £10,000 in older examples, though insurance groups are higher (around 20–22). The standard Boosterjet is the better all-round choice for most buyers.

10. Renault Clio 0.9 TCe (2016+)

The Renault Clio offers distinctive French styling, a comfortable ride, and one of the most spacious cabins in the supermini class. The 0.9 TCe turbocharged petrol engine is small but willing, and fuel economy is competitive.

• Typical price: £5,500–£7,500
• Fuel economy: 48–54 MPG (combined)
• Insurance group: 8–12
• Euro standard: Euro 6
• CAZ compliant: Yes — all UK zones

The Clio is often the cheapest car on this list, making it an excellent entry point for budget-conscious buyers who want a compliant, economical car with a bit of character.
