Is a Euro 4 petrol enough for the ULEZ?

Yes. TfL's ULEZ standard for petrol cars is Euro 4, so a Euro 4 car meets it exactly and pays no daily charge anywhere in the zone.

Do I need to register the car with TfL?

Not if it is UK-registered; cameras read the plate against the DVLA record. A car registered outside the UK must be registered with TfL even though it meets the standard.

What if the car turns out not to be compliant?

It would owe £12.50 for each day driven in the zone, payable by midnight on the third day after. Unpaid, that becomes a £180 penalty, reduced to £90 if paid within 14 days. TfL's online vehicle checker settles the question in advance.

Does the Congestion Charge apply?

Yes, in central London during charging hours, whatever the emissions class: £18 a day if paid in advance or on the day, £21 if paid by midnight on the third day after.

Can a petrol Euro 4 car enter London?

Yes. A petrol Euro 4 vehicle from 2018 meets London’s ULEZ standard, which requires a minimum of Euro 4 for petrol vehicles. It pays nothing to drive in the zone.

Being exactly on the line means the paperwork decides it. Check the Euro class on the V5C or the Certificate of Conformity, or enter the plate in TfL’s vehicle checker. If the record shows Euro 4 or later, the car is compliant.

How the zone works

The ULEZ covers all London boroughs, the M25 itself excepted, and operates 24 hours a day, every day except Christmas Day. There is no sticker or permit; cameras read the plate. A UK-registered compliant car needs no action. A car registered outside the UK must be registered with TfL even if it meets the standard.

Had the car fallen short, it would owe £12.50 for each day driven in the zone, due by midnight on the third day after, and £180 (£90 within 14 days) if left unpaid.

The Congestion Charge still applies

Central London’s Congestion Charge is a separate daily fee that ignores emissions class: £18 if paid in advance or on the day, £21 if paid by midnight on the third day after. Hours are 07:00-18:00 Monday to Friday and 12:00-18:00 at weekends and bank holidays, with no charge from Christmas Day to the New Year’s Day bank holiday.
