Vehicle Incorrectly Categorised (ULEZ/CAZ)

If your vehicle has been incorrectly categorised as non-compliant with the Ultra Low Emission Zone or Clean Air Zone, you can challenge on factual grounds.

Legal basis

Vehicle categorisation rules for ULEZ/CAZ; DVLA vehicle records.

How to identify this in your case

Check TfL ULEZ checker or relevant CAZ checker with your VRM. Compare against V5C and actual vehicle specifications.

Sample appeal wording

Before you send this

Deadline. A late submission can be turned down without your argument being read. Check your notice for the deadline and how it is counted.
Paying may end it. Paying can count as accepting the notice and can close a challenge already under way. Part-paying or acknowledging an old debt can also revive a time limit that had expired.
The amount can change. Check what happens to the sum if you challenge — it may be held, re-offered lower, or keep rising, and fees or enforcement can continue meanwhile.
Use the official route. Use the method, recipient and form your notice specifies, with any reference, evidence and signature it asks for. Sent elsewhere, it may not count.
Only say what is true. Do not copy any statement of fact unless it is true for you, and check the legal point still applies. Delete what does not fit. It may be treated as your statement.
Careful what you volunteer. Avoid unnecessary admissions — naming the driver or accepting responsibility can remove arguments. But answer anything you are legally required to answer, and do include the evidence your ground needs.
Keep the record. Keep what you sent, the attachments, any receipt, and the reply. Note the next deadline.

Sample wording to adapt and send yourself — it may not fit your notice or the stage you are at. Replace the bracketed prompts with your own details; leave any case citation as it is.

I challenge this charge on the basis that my vehicle [VRM] is incorrectly recorded in your system. My vehicle is a [MAKE/MODEL/YEAR] with a Euro [X] engine which meets the ULEZ/CAZ emissions standards. I enclose a copy of my V5C showing the emissions data. Please correct your records and cancel this PCN.
