Received a Penalty Charge Notice from Transport for London (TfL)? You are not automatically liable just because a notice arrived. You normally have 28 days to lodge a challenge, so act early. This guide covers the official appeal route, the grounds that actually work, and the evidence to attach. When you are ready, the free Parksy fine appeal letter generator reads a photo of your notice and drafts the letter for you — no sign-up needed to start.

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 Transport for London (TfL) appeal process works
TfL issues Penalty Charge Notices for red route stopping, banned turns and other moving-traffic contraventions on the Transport for London Road Network — these are statutory penalties, not private parking charges, and the process is fixed by law. You can make an informal challenge within 28 days of the PCN date via TfL's challenge portal; pay within 14 days instead and the amount is halved.
If the informal challenge is rejected (or you did not make one), TfL serves a Notice to Owner, opening a 28-day window for formal representations on the statutory grounds — contravention did not occur, you were not the owner, the vehicle was taken without consent, and others. Missing the formal-representations deadline forfeits your right to the tribunal.
If TfL rejects your formal representations you have 28 days to appeal to London Tribunals, the free independent adjudication service, where an adjudicator reviews TfL's evidence (usually CCTV) against yours. Red route cases frequently turn on signage visibility, whether an exemption applied (loading, picking up a passenger, medical emergency), and the quality of the CCTV record — request TfL's footage early, precisely because the adjudicator will.
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 Transport for London (TfL) rejects your appeal?
A first-stage rejection is not the end of the road. You can escalate to London Tribunals, which is independent of Transport for London (TfL) 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.

How do I challenge a TfL red route PCN?
Start with an informal challenge within 28 days at tfl.gov.uk/modes/driving/challenge-a-pcn, stating your grounds and attaching evidence. If TfL rejects it and later serves a Notice to Owner, make formal representations within 28 days on the statutory grounds; if those are rejected you have 28 days to appeal to London Tribunals, the free independent adjudicator. Each stage has its own hard deadline, and missing the formal-representations window costs you the tribunal right — diarise every letter the day it arrives.
Should I pay the 50% discount or fight the PCN?
Paying within 14 days halves the penalty but closes the case. If you challenge informally within that window and lose, TfL commonly re-offers the discount for a further 14 days from its rejection — so an early, well-founded challenge costs you little. Weigh your evidence honestly: statutory exemptions (loading, boarding passengers, breakdown, medical emergency) and unclear signage are genuine grounds; inconvenience is not. If the CCTV plainly shows a contravention with compliant signs, the discount is usually the rational outcome.
What counts as stopping on a red route?
Double red lines prohibit stopping at any time; single reds prohibit stopping during the hours signed. Genuine exemptions include boarding or alighting passengers where permitted, licensed taxi activity, loading in marked red-route loading boxes during permitted hours, breakdowns, and complying with a police direction. TfL enforces by CCTV, so the footage decides most cases: request it early. If your stop falls inside an exemption, state which one, with times, and support it — a blue badge, a delivery record, or a breakdown call-out log.
What is London Tribunals and does it cost anything?
London Tribunals (the Environment and Traffic Adjudicators) is the free, independent tribunal that decides appeals against London PCNs, including TfL's. You appeal within 28 days of TfL rejecting your formal representations; hearings are decided on the papers, by phone, or in person, and the adjudicator's decision binds TfL. There is no fee and costs are rarely awarded against motorists. Adjudicators can also refer cases back to TfL to reconsider discretion even where a contravention technically occurred.
What happens if I ignore a TfL PCN?
The penalty escalates on a statutory track: after the Notice to Owner and any rejected representations, TfL issues a Charge Certificate increasing the amount by 50%, then registers the debt at the Traffic Enforcement Centre, after which enforcement agents (bailiffs) can be instructed and their fees added. Unlike private parking charges, this process does not require TfL to sue you first. If deadlines have already passed, limited routes such as a witness statement at the TEC may still exist — act rather than wait.
