Grounds to appeal a City of London Corporation Penalty Charge Notice
Appeals built on one specific, evidenced ground beat generic complaint letters. The strongest grounds are:
- The signs or road markings were missing, obscured, or contradictory
- The contravention did not occur as described (wrong code, wrong location, vehicle not there)
- The PCN or notice contains errors — wrong registration, date, or location details
- You were loading/unloading, or stopped due to circumstances beyond your control (breakdown, medical emergency)
- A valid ticket, permit, or exemption applied at the time
- The vehicle was stolen or had been sold before the contravention date
- The penalty exceeds the amount applicable for the alleged contravention
- Procedural failures by the authority (notice served late or to the wrong party)
How the City of London Corporation appeal process works
The City of London Corporation is not a London borough - it governs the historic Square Mile - but its parking PCNs are civil enforcement under the Traffic Management Act 2004 like any London authority, and appeals go to London Tribunals. Kerbside control is close to total: the kerbside within the City's Controlled Parking Zone is subject to yellow-line restrictions, and enforcement is delivered by uniformed Civil Enforcement Officers from contractor Marston Holdings with handheld computers and cameras. Loading is tightly policed - a maximum of 40 minutes, with CEOs observing a private vehicle for five minutes and a commercial vehicle for ten before issuing a PCN if no continuous loading activity is seen. Typical contraventions involve loading bays, single yellow lines, meter bays and suspended bays.
You can pay, challenge or view CCTV/photographic evidence of your PCN on the City's online portal (cityoflondon.tarantoportal.com). You have 28 days from the notice date to make a representation. If it is received within 21 days it is considered at the discounted amount, and if rejected the 50 per cent discount is re-offered for a further 21 days; the case is held with no escalation until a response is sent.
If the PCN goes unpaid, a Notice to Owner is served and the registered keeper has 28 days to make formal representations, which the authority must answer within 56 days. A Notice of Rejection triggers a 28-day window to appeal to London Tribunals (Environment and Traffic Adjudicators) using the 'Your Right to Appeal' form supplied with the rejection.
Evidence to include
- Photos of the signage as you saw it — position, height, legibility (wide shots and close-ups)
- Your ticket, permit, receipt, or app payment confirmation
- Photos of the location, bay markings, and any machines (including error screens)
- The notice itself, both sides
- Witness statements if someone was with you
- Breakdown/recovery or medical documentation where relevant
Unsure what the signs at the site actually permit? Photograph them and run them through the free Parksy parking sign scanner — it decodes the restrictions in plain English, which often reveals the exact defect your appeal should lead with.
What if City of London Corporation rejects your appeal?
A first-stage rejection is not the end of the road. You can escalate to London Tribunals, which is independent of City of London Corporation and free for motorists to use. Escalation deadlines are stated in the rejection letter — diarise them the day it arrives, and reuse your original evidence with any gaps the rejection pointed out now fixed.

Frequently asked questions
How do I challenge a City of London parking PCN?
Challenge online through the City of London's 'Challenge a ticket' page on cityoflondon.gov.uk, which feeds its penalty charge notice portal (cityoflondon.tarantoportal.com/PCNs). Enter your PCN number and vehicle registration to view the Civil Enforcement Officer's photographs or CCTV footage before deciding - this evidence is often decisive in Square Mile cases involving loading observation. Submit your representation with any supporting evidence: delivery notes proving loading, a valid pay-by-phone session, photographs of obscured signs or bay markings. You have 28 days from the date of the notice to make a representation, and the Corporation holds the case with no escalation until it responds. If it accepts your challenge the PCN is cancelled; if not, you receive a Notice of Rejection with a further 28 days to pay or appeal. Do not pay first, as payment closes the case and ends the challenge.
Do I keep the 50 per cent discount while challenging a City of London PCN?
Yes, if you move quickly. The City of London applies an unusually generous published policy: if your representation is received within 21 days of the date of the notice, it is considered at the discounted (50 per cent) amount, and if it is rejected you are re-offered the discount for a further 21 days from the rejection. So a prompt challenge costs you nothing even if it fails. If you submit after 21 days, the Corporation will still consider and respond to your representation, but a rejection then leaves you liable for the full penalty amount rather than the discounted one. The practical rule in the Square Mile is therefore: review the portal evidence and lodge your challenge within three weeks of the PCN being issued. Once the case reaches the formal Notice to Owner stage, the discount is no longer available and the full charge applies.
What happens after rejection or at the Notice to Owner stage?
If your initial challenge is rejected and the PCN remains unpaid, the City of London Corporation serves a Notice to Owner on the registered keeper. The keeper then has 28 days to pay in full or make formal representations on the statutory grounds listed on the notice. The authority must respond within 56 days of receiving representations; if it fails to do so, it is deemed to have accepted them. If the representations are refused, you receive a formal Notice of Rejection, which starts a final 28-day window to appeal to London Tribunals (Environment and Traffic Adjudicators). To appeal, complete the 'Your Right to Appeal' application form supplied with the Notice of Rejection and return it to the address on the form - not to the Corporation. The tribunal is free, independent, can hear cases in person, by phone or on the papers, and its decision binds the authority.
What are strong grounds for appealing a City of London PCN?
Because most City PCNs arise from yellow-line and loading enforcement, the strongest ground is usually that the contravention did not occur: you were actively loading or unloading. City of London CEOs must observe a private vehicle for five minutes and a commercial vehicle for ten looking for loading activity before issuing, and loading is permitted for up to 40 minutes where no loading ban applies - so delivery paperwork, timestamps and witness evidence showing continuous activity can defeat the observation record. Other statutory grounds include defective, missing or obscured signs and lines, a valid payment or permit, not being the owner at the time (with transfer dates), the vehicle being taken without consent, the penalty exceeding the applicable amount, an invalid traffic order, or improper service of the PCN. Always check the CEO's photographs on the portal first, and address what they show directly in your representation.
What happens if I ignore a City of London PCN?
Ignoring it makes the debt grow through fixed statutory stages. After 28 days the Corporation serves a Notice to Owner on the registered keeper; if that is ignored, it issues a Charge Certificate increasing the penalty by 50 per cent, so a 160 GBP charge becomes 240 GBP. If the increased amount is still unpaid after 14 days, the debt is registered at the Traffic Enforcement Centre at Northampton County Court and an Order for Recovery is served, adding a court fee. Unless you file a valid witness statement - for instance that you never received the Notice to Owner or had already paid - the Corporation can obtain a warrant of control and instruct enforcement agents (bailiffs), whose statutory fees start at 75 GBP for the compliance stage and 235 GBP or more at enforcement, and who may clamp or remove the vehicle. Each ignored stage also extinguishes a right of challenge you cannot get back.
