Parked in a car park without payment of the parking charge (code 73)
Contravention code 73 — "Parked without payment of the parking charge" — is one of the standard car-park (off-street) contraventions that councils enforce under the Traffic Management Act 2004. The off-street twin of code 11 — a council car park where no payment was recorded. App outages, a mistyped registration and out-of-order machines are the common causes, and all are evidenced easily. A council PCN is a statutory civil penalty, not a private invoice, so it must be challenged through the proper channel within the deadlines — but codes are misapplied more often than drivers expect, and a rejected challenge can be taken, free, to an independent adjudicator.

Grounds for challenging a code 73 PCN
Pick the statutory ground that genuinely fits your situation — including the ones below that are specific to code 73.
- The contravention did not occur — for example you were parked or driving lawfully, a valid ticket, permit or exemption applied, or the restriction was not in force at that time.
- The signs, road markings or the Traffic Regulation Order did not comply with the regulations (TSRGD), so the restriction was not lawfully indicated.
- There was a procedural error — the PCN, the Notice to Owner, or the statutory wording or timing was defective.
- You were not the owner/keeper when it was issued, the vehicle had been taken without consent, or you are a hire firm with a valid hiring agreement.
- The penalty exceeded the amount applicable in the circumstances, or there are compelling mitigating circumstances the authority should consider.
- You did pay — a card statement or parking-app receipt timestamped within the parked period rebuts the allegation.
- You entered your registration incorrectly in the app; the payment exists and can be matched to your card.
- The machines were out of order and no working payment method was available.
How to appeal, step by step
- 1
Gather your evidence
Note the PCN number, vehicle registration, date, time and location, and collect proof — photos of the signs and road markings (or the box-junction/bus-lane layout), a valid permit, ticket or Blue Badge, or the camera images the council relies on.

Make an early challenge within 14 days
Challenge the PCN with the council as soon as possible, setting out your ground and attaching evidence. Acting within 14 days protects the 50% discount — most councils freeze it while they consider an early challenge.

If the council rejects your challenge it will serve a Notice to Owner. Respond with formal representations on a statutory ground within 28 days — do not ignore it.
- 5
Appeal to the independent tribunal if rejected
If your representations are rejected, you can appeal — free — to an independent adjudicator: London Tribunals in London, or the Traffic Penalty Tribunal elsewhere in England & Wales. You do not have to pay first.

Code 73 PCNs — frequently asked questions
What does PCN contravention code 73 mean?
Code 73 is the national civil-enforcement code for "Parked without payment of the parking charge" — a car-park (off-street) contravention under the Traffic Management Act 2004. Some authorities add an official letter suffix that pins down the exact circumstances — for code 73 the published variants are 73u (electronic payment). The code on your notice, together with the camera images or the enforcement officer's observation, is what defines the alleged contravention.
How much is a code 73 PCN, and is there a discount?
The penalty is £110 in inner London (Band A) or £90 in outer London (Band B), and typically around £50 elsewhere in England. Most councils freeze the 50% discount while they consider a challenge made within the first 14 days — so challenge promptly rather than paying if you believe the PCN is wrong.
Can I appeal a code 73 PCN?
Yes. Challenge it with the council first — informally and as soon as possible. If that is rejected and a Notice to Owner is served, make formal representations within 28 days. If those are rejected too, you can appeal for free to an independent adjudicator — London Tribunals in London, or the Traffic Penalty Tribunal elsewhere in England & Wales — and you do not have to pay the penalty before the tribunal decides.
Can AppealIQ write my code 73 appeal letter?
Yes. Enter your PCN details and the ground that genuinely fits, and AppealIQ drafts a formal, statute-aware challenge letter you can send to the council or use at the tribunal. Your first letter each calendar month is free.
What do the letter suffixes on code 73 mean (73u)?
They narrow the contravention to a specific circumstance: 73u (electronic payment). The suffix is set by the authority that issued the notice, so appeal against the exact code printed on your PCN — not the bare number.
