Appeal My Fine — £9.99Why congestion charge PCNs are worth challenging
The congestion charge system relies on ANPR cameras and automated payment processing. This means errors can occur at multiple points: the camera may misread a plate, payments may not be processed correctly, auto-pay may fail silently, and exemptions may not be applied. TfL issues PCNs automatically without human review, and many are cancelled when drivers submit properly structured appeals.
The congestion charge appeal timeline
- Day 1-14: Pay at 50% discount (£80) OR submit informal challenge
- Day 1-28: Make formal representations to TfL
- If TfL rejects: Appeal to London Tribunals (free, independent)
- After 28 days: PCN increases to full £160
- After 56 days: Risk of enforcement centre registration and bailiff action
Building your case
The most effective congestion charge appeals include clear documentary evidence. For payment disputes, provide bank statements, TfL payment confirmations, or account activity logs. For auto-pay failures, show your account settings and payment method were active. For exemptions, provide vehicle registration documents showing the vehicle type or disability badge details. For diversions, document the road closures or diversion signs you encountered.
London Tribunals — your free backup
If TfL rejects your representation, you can appeal to London Tribunals at no cost. This is an independent adjudication service that reviews the evidence from both sides. The adjudicator is legally qualified and their decision is binding on TfL. Many appeals that are rejected by TfL are subsequently upheld by London Tribunals, so it is worth escalating if you believe your case has merit.
Frequently asked questions
What happens if I don't pay the congestion charge PCN?
If you don't pay or appeal within 28 days, the PCN increases to £160. After 56 days, TfL can register the debt at the Traffic Enforcement Centre and apply to bailiffs for recovery. Always either pay or appeal within 28 days.
Can I appeal if I was just passing through the zone?
Simply driving through the congestion zone during charging hours triggers the charge. However, if you were diverted into the zone by official road closures or diversions, this is a valid ground for appeal.
How do I check if my vehicle is exempt?
Check on the TfL website using your registration number. Exempt categories include 100% electric vehicles, disabled Blue Badge holders (must register), residents (90% discount, must register), military vehicles, and NHS vehicles on emergency calls.
