Is the Citroen C4 ULEZ compliant?

Most petrol Citroen C4s from 2006 and diesels from September 2015 meet the Euro standards for London ULEZ and other UK clean-air zones, so they are generally exempt from the daily charge. Pure-electric versions are always exempt.

What insurance group is the Citroen C4 in?

The Citroen C4 sits in insurance group 15 of 50, towards the cheaper end of the scale. Your actual premium still depends on age, postcode, annual mileage and no-claims history.

Is the Citroen C4 reliable?

Our reliability score for the Citroen C4 is 60 out of 100 (about average), derived from DVSA MOT records, with a first-time MOT pass rate of about 77% at the reference age.

What economy does the Citroen C4 get?

Expect roughly around 53 mpg combined for a typical Citroen C4, based on official figures and our running-cost model. Real-world figures vary with driving style, load and conditions.

What are the common problems on the Citroen C4?

On the Citroen C4, the issues that come up most by mileage include Suspension, Lighting & signalling and Tyres & wheels. The section above breaks down each one with its typical mileage, repair cost and severity.

How many Citroen C4s are on UK roads?

About 182,365 Citroen C4s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

Is the Citroen C4 reliable?

The Citroen C4 scores 60/100 on Forecourt's MOT-based reliability measure, ahead of 10% of the cars we track. That is computed from 3,587,020 real DVSA MOT test results.

How much does a used Citroen C4 cost?

A 2023 Citroen C4 with around 26,850 miles is worth roughly £13,300 today (typical range £12,000–£14,550). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.

How quickly does the Citroen C4 depreciate?

A new Citroen C4 typically loses about 35% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.

What insurance group is the Citroen C4?

The Citroen C4 sits in insurance group 15 of 50 — the cheaper end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.

What goes wrong on a used Citroen C4?

The most common age-related issues we track for the Citroen C4 are: suspension (typically around over 100k miles, £150-£450 to put right); lighting & signalling (typically around over 100k miles, £15-£120 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.

What does the Citroen C4 cost to run?

Expect around 53 mpg combined, £195 a year in road tax, about £185 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.

Safety rating

Euro NCAP's independent crash-test rating for the Citroen C4, from its 2021 assessment.

4/5

TEST YEAR2021

Rating expired (test protocol superseded)

The passenger compartment of the C4 remained stable in the frontal offset test.

Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014.

A 3-year-old C4 passes its MOT 82.1% of the time; by 22 years that has slipped to 54.5%. The y-axis is zoomed to this model’s range so the trend is readable.

Things owners say

01The 1.2 PureTech petrol uses a wet belt with a patchy reliability history - insist on up-to-date belt and oil service.
02Comfort is the priority - the soft ride is a strong point, but it's not a keen driver's car.
03The e-C4 is a comfortable, easygoing EV; verify battery health and that real-world range suits you.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Citroen C4, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Around average

Theft risk is around the UK average. Like most modern cars it has keyless entry, so relay theft is the method to guard against.

Parts theft

Higher

Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.

Worth doing

Keep keys in a Faraday pouch and away from the front door to block relay attacks.
A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.

Clean-air zones

Whether driving a Citroen C4 into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Charging zones for cars

City	Area	Daily charge	Likely outcome
London	All of Greater London (within the M25)	£12.50	Likely exempt Diesel from September 2015 meets Euro 6.
Birmingham	Inside the A4540 Middleway	£8.00	Likely exempt Diesel from September 2015 meets Euro 6.

Company car tax

What HMRC's Benefit-in-Kind charge looks like if you ran this Citroen C4 as a company car, by tax year and income-tax band. Calculated from a CO₂ of 121 g/km, using £25,500 as the P11D value.

Tax year	BIK %	Tax @ 20%	Tax @ 40%	Monthly @ 20%	Monthly @ 40%
2025-26	29%	£1,479	£2,958	£123	£247

P11D value is approximated from the latest new price; the exact figure on your tax code will depend on options fitted. The 4% diesel surcharge applies only to non-RDE2 (pre-2021) diesels — we assume RDE2 compliance for current models. Bands and rates from HMRC's Autumn Budget 2024 confirmation through 2029/30.

Common questions

Citroen C4, answered from the data

Is the Citroen C4 reliable?: The Citroen C4 scores 60/100 on Forecourt's MOT-based reliability measure, ahead of 10% of the cars we track. That is computed from 3,587,020 real DVSA MOT test results.
How much does a used Citroen C4 cost?: A 2023 Citroen C4 with around 26,850 miles is worth roughly £13,300 today (typical range £12,000–£14,550). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the Citroen C4 depreciate?: A new Citroen C4 typically loses about 35% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
What insurance group is the Citroen C4?: The Citroen C4 sits in insurance group 15 of 50 — the cheaper end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
What goes wrong on a used Citroen C4?: The most common age-related issues we track for the Citroen C4 are: suspension (typically around over 100k miles, £150-£450 to put right); lighting & signalling (typically around over 100k miles, £15-£120 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the Citroen C4 cost to run?: Expect around 53 mpg combined, £195 a year in road tax, about £185 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
