You already paid the Clean Air Zone charge

Most Clean Air Zone (CAZ) daily charges can be paid from 6 days before to 6 days after your journey. If you paid the correct daily charge, for the date and the vehicle shown on the penalty charge notice (PCN) — that is, the fine — within that window, the PCN should be cancelled. Keep the payment receipt from the GOV.UK Clean Air Zone payment service showing the same date and number plate.

Legal basis

Clean Air Zone Charging Order (the local charging scheme order); Transport Act 2000 s.163

How to identify this in your case

Check for a payment receipt from the GOV.UK Clean Air Zone payment service for the same date as your journey and the same number plate as the vehicle on the PCN.

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.

Daily charge paid — PCN administrative error. The Clean Air Zone daily charge for the vehicle was paid within the permitted payment window for the date of the alleged contravention; the PCN should be cancelled.
