Appeal My Fine — £9.99Understanding Clean Air Zone charges
Clean Air Zones use ANPR cameras to identify non-compliant vehicles entering designated areas. Charges vary by city and vehicle type — typically £8-£50 per day for cars and vans, and up to £100 for HGVs and buses. If the daily charge is not paid, a PCN is issued, usually for £120 (reduced to £60 if paid within 14 days).
Common grounds for appealing a CAZ fine
- Your vehicle meets the required emission standards but was incorrectly classified
- You applied for a local exemption or temporary exemption that was not processed
- The payment system experienced errors when you attempted to pay
- The ANPR camera misread your number plate
- You were directed into the CAZ by official diversions or roadworks
- You sold the vehicle before the charge date
- Your vehicle qualifies for a national or local exemption (military, historic, disabled)
How to submit your appeal
Submit a formal representation to the local authority that issued the PCN within 28 days. Include your PCN reference, vehicle details, grounds for appeal, and supporting evidence. If rejected, you can escalate to the Traffic Penalty Tribunal at no cost. The adjudicator's decision is final and binding on the council.
Key evidence for your appeal
Strong evidence includes MOT certificates showing your emission class, V5C documents proving vehicle sale, payment confirmation or bank statements, exemption application receipts, and any correspondence with the local authority. Screenshots of website errors or system downtime can also support payment failure claims.
