Parked in a place not designated for that class of vehicle (code 23)
Contravention code 23 — "Parked in a parking place or area not designated for that class of vehicle" — is one of the standard parking contraventions that councils enforce under the Traffic Management Act 2004. Issued where the bay is reserved for a particular class of vehicle — for example a motorcycle/solo bay, or a goods-vehicle bay — and a different class of vehicle is parked there. 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 23 PCN
Pick the statutory ground that genuinely fits your situation — including the ones below that are specific to code 23.
- 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.
- Your vehicle did match the permitted class for that bay.
- The signs or markings did not specify which class of vehicle the bay was for, or the bay was dual-use.
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.

Pick the ground that fits code 23
Choose the statutory ground that genuinely matches your situation for "Parked in a parking place or area not designated for that class of vehicle". A focused, evidenced argument beats a scattergun one.
- 3
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.
- 4
Make formal representations if a Notice to Owner follows
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 23 PCNs — frequently asked questions
What does PCN contravention code 23 mean?
Code 23 is the national civil-enforcement code for "Parked in a parking place or area not designated for that class of vehicle" — a parking contravention under the Traffic Management Act 2004. Your council may word it slightly differently and may add a letter suffix (for example 23a) that pins down the exact circumstances. 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 23 PCN, and is there a discount?
The penalty is £160 in inner London (Band A) or £140 in outer London (Band B), and typically around £70 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 23 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 23 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.
