How to Challenge a Code 63 PCN for Leaving an Engine Running

What a Code 63 PCN Alleges

Code 63 describes a parking contravention for an engine left running where prohibited. Councils can also use separate fixed-penalty powers for engine idling: those are not the same notice or appeal process. Start by identifying a civil parking PCN and the parking-place or waiting order relied upon. A coach waiting for passengers is a common context, but the allegation is about the running engine and applicable prohibition, not merely the type of vehicle.

On-Street Parking: PCN, Notice to Owner and Formal Representations

A parking PCN served at the vehicle can be challenged before a Notice to Owner arrives. The later notice is a separate statutory step, not merely another copy of the original ticket. Identify the document you have and send the challenge at that stage.

• PCN on the windscreen or handed to the driver: send an informal challenge to the issuing authority. Explain the disputed parking condition and attach the evidence that supports cancellation.
• Notice to Owner: if one is served, the owner makes formal representations against it. Repeat the relevant evidence and address any earlier rejection; an informal challenge does not replace this response.
• Postal parking PCN: make formal representations against the postal PCN without waiting for a Notice to Owner. The authority needs a lawful basis for postal service, such as qualifying prevented service, a drive-away after the officer began preparing the PCN, or an eligible approved-device case.
• Notice of Rejection: appeal to the tribunal named in that notice. London civil parking cases go to London Tribunals; relevant English and Welsh cases outside London go to the Traffic Penalty Tribunal.

England's camera powers for on-road parking are restricted; the presence of a camera does not authorise postal enforcement of every paid bay. The traffic order and signs govern the restriction, while the notice's legislation governs the procedure. Wales has separate regulations, and local-Act restrictions need their own check.

Parking Challenge Deadlines and the Council's Reply

A PCN served on the vehicle or driver normally allows 14 days at the discounted amount. Challenge promptly and check the council's policy on re-offering the discount. Do not assume that asking for photographs or reporting a machine fault pauses the PCN.

• A Notice to Owner normally gives 28 days beginning with service for formal representations. Use its reference and instructions even if the first challenge has already been sent.
• An English postal parking PCN normally gives 28 days beginning with service for formal representations. The discount is normally 21 days for an approved-device notice and 14 days for qualifying prevented-service or drive-away notices.
• For qualifying formal parking representations in England, the authority must serve its decision within 56 days of receipt. This statutory requirement does not turn every unanswered informal email into an accepted appeal.
• A formal Notice of Rejection normally gives 28 days beginning with service to appeal to the tribunal. Keep the rejection and submission confirmations so the dates can be established.

London Councils publishes borough parking penalties of £160 higher level and £110 lower level in Band A, and £140 and £90 in Band B. The applicable code, location and date determine the amount. TfL and authorities outside London have their own applicable charges; these borough amounts are not national rates.

Engine Logs, Officer Notes and the Council's Idling Policy

• The notice showing whether this is a Penalty Charge Notice or a separate Fixed Penalty Notice.
• The officer's observations, any video or audio, and records of a request to switch off and the driver's response.
• Vehicle telematics or a manufacturer's explanation distinguishing combustion-engine operation from electrical accessories.
• The applicable parking order, place conditions and enforcement policy in force on the date.
• Any engineering, emergency or welfare evidence relevant to a claimed exception or request for discretion.

An engine left running is not proved solely by the driver sitting in the vehicle. Equally, switching it off after the officer has recorded the contravention does not necessarily cancel the PCN; explain the sequence and any policy requiring a warning.

Was the Engine Running in a Place Covered by the Prohibition?

• The engine was not running: ask what the officer saw or heard. A dashboard display, heater fan or hybrid vehicle in an electrical ready mode is not necessarily proof that the combustion engine was idling.
• The vehicle was not parked: identify whether it was stopped by traffic conditions rather than waiting voluntarily. Supply the movement sequence rather than relying on one photograph.
• The prohibition did not cover that parking place or time: ask for the order and relevant signs or published conditions. A general clean-air campaign does not itself identify the enforceable parking restriction.
• The council did not follow an applicable warning policy: compare its policy with the officer's notes. For example, Southwark's published protocol says to ask the driver to switch off or move first; that local policy should not be assumed to apply identically everywhere.
• A specified exception or genuine necessity applied: provide technical or emergency evidence and match it to the applicable provision. A preference for a warm cab or convenient air conditioning is not, on its own, proof of an exemption.

Separate vehicle-emissions legislation and parking orders can have different conditions and exceptions. Do not transfer a fixed-penalty warning requirement or a machinery exemption to code 63 without checking the provision used. If the PCN is valid but there were exceptional welfare circumstances, explain those as a request for discretion.

What to Include in a Code 63 Challenge

Identify the parking prohibition used and answer the evidence that the engine was running. If the published policy required an earlier request to switch off, quote that policy and explain what happened. If the document is a separate emissions Fixed Penalty Notice, use its stated procedure instead of the parking Notice to Owner process below.

Where to Send the Parking Challenge

Use the issuing authority's online PCN service or the postal address on the current notice. Include the PCN number, registration, street and a concise explanation connecting each ground to its evidence. Save the completed submission, attachments and acknowledgement.

For formal representations, select the applicable ground and explain it in your own factual account. A sale, qualifying hire agreement or vehicle taken without consent needs the relevant supporting records. Naming a different driver alone does not transfer ordinary council-PCN liability away from the owner.

After Rejection: Formal Representations and the Tribunal

An informal rejection leaves the option of formal representations if a Notice to Owner is served. A formal Notice of Rejection enables an independent tribunal appeal. Focus on the issue the council has not answered, whether that is a valid payment, a permitted activity, an unclear restriction or a procedural error.

If the adjudicator allows the appeal, the penalty is cancelled. If refused, follow the decision's payment instructions. Missing the payment or appeal deadline can lead to a 50% increase at Charge Certificate stage and later an Order for Recovery. These later notices have specific procedural remedies and should not be treated as another ordinary opportunity to dispute the parking event.
