I received a parking penalty charge notice. How do I challenge it?

Short answer

A penalty charge notice (PCN) from a local authority follows a strict civil process. You can challenge informally within 28 days, then formally once a Notice to Owner is issued, then appeal free of charge to the independent Traffic Penalty Tribunal. Acting at the right stage matters — the charge is discounted by 50% if paid within 14 days, but challenging does not extend the discount window automatically.

PCNs issued by local authorities under the Traffic Management Act 2004 are civil, not criminal. They are different from Fixed Penalty Notices issued by police for moving traffic offences (speeding, mobile phone use), which are criminal penalties with different challenge routes.

1 The rule

Local authority parking enforcement in England is governed by the Traffic Management Act 2004 and the regulations made under it. The process has three stages: informal challenge, formal representation, and appeal to an independent adjudicator.

The three-stage process is sequential — you must exhaust each stage before moving to the next. However, you can appeal to the independent adjudicator (Traffic Penalty Tribunal or London Tribunals) without any risk of cost penalty — there is no fee, and success rates for well-evidenced appeals are significant.

2 What you can do now

1. 1
   Read the PCN carefully

   Note the date, location, the contravention code (a two-digit number identifying the alleged breach), and the payment deadline. The discount period is 14 days from the date of issue — if you intend to pay, pay within this window. If you intend to challenge, you still need to act within 28 days to make an informal representation. Check whether the PCN was issued on street (affixed to the vehicle or handed to the driver) or by post (a postal PCN, usually from camera evidence).

2. 2
   Gather your evidence

   Collect everything relevant: photographs of the location (especially signage and road markings) taken as soon as possible; your vehicle's location records if you have a dashcam or have parked elsewhere; any permits, blue badges, or loading evidence; and any contemporaneous notes. Good photographs of missing, obscured, or ambiguous signage are the most common winning ground.

3. 3
   Make an informal representation to the issuing authority

   Write to the council (or, in London, TfL or the issuing London borough) within 28 days of the PCN. Set out your grounds clearly and concisely: the signage was unclear or missing; the restriction was not in force at the time; you had a valid permit; the vehicle had broken down; the PCN was issued in error. Attach your photographs and any supporting documents. The authority must respond within 56 days. If they fail to do so, the PCN is cancelled.

4. 4
   Make a formal representation after the Notice to Owner

   If your informal challenge is rejected, the authority will issue a Notice to Owner (NoO) to the registered keeper. You then have 28 days to make a formal representation. The authority must issue a formal Notice of Rejection if they refuse it. This step is mandatory before you can appeal to the independent adjudicator. Set out your grounds in full — this document will be your evidence bundle before the tribunal.

5. 5
   Appeal to the Traffic Penalty Tribunal

   After a formal rejection, appeal to the Traffic Penalty Tribunal (outside London) or London Tribunals (inside London) within 28 days. The appeal is free. You may present your case in writing or request an oral hearing. The adjudicator considers the evidence independently and is not bound by the authority's decision. If you win, the PCN is cancelled entirely. If you lose, you must pay the reduced charge (the discount amount usually applies even after a failed appeal in the discretion of the authority).

3 When this does not apply

• The PCN was issued by police for a moving traffic offence (speeding, mobile phone use, traffic lights) — these are criminal Fixed Penalty Notices, not civil PCNs, and must be challenged differently.
• The PCN was issued in a private car park (supermarket, shopping centre) — these are not civil enforcement notices but contractual demands governed by the Protection of Freedoms Act 2012. The challenge route is the Parking on Private Land Appeals (POPLA) service.
• The vehicle is in Wales — although the statutory framework is similar, some Welsh councils use different procedures under the Cardiff and Vale area order.
