parking contravention
Parked in a suspended bay or space
This contravention is enforced under the Traffic Management Act 2004. The council must be able to prove the restriction was properly signed, properly ordered and correctly observed on the day.
No account, no card, nothing stored.
Grounds that work against code 21
The contravention did not occur
Ask the council for the enforcement officer's contemporaneous notes, every photograph taken, and the Traffic Regulation Order in force on that date. If any of the three is missing or inconsistent, say so.
Signs or markings were not compliant
Signs and road markings must meet the Traffic Signs Regulations and General Directions and be visible to a driver taking reasonable care. Faded lines, obscured plates and missing repeaters are common.
Evidence to attach
- A copy of the Penalty Charge Notice
- Photographs of the signs and road markings at the exact location
More appeals fail on missing evidence than on weak arguments. Send copies, never originals, and keep a proof of posting.

Common questions
What does contravention code 21 mean?
Code 21 means parked in a suspended bay or space. It is a parking contravention enforced by a council under the Traffic Management Act 2004, and it appears on your Penalty Charge Notice next to the description of the alleged contravention.
Can I appeal a code 21 PCN?
Yes, and it costs nothing. Challenge the council first, ideally within 14 days so the 50% discount is protected. If they reject you, a Notice to Owner follows, then formal representations, and finally a free appeal to an independent adjudicator.
How much is a code 21 penalty?
Council penalty charges generally run from £60 to £130 depending on the authority and whether the contravention is treated as higher or lower level. Paying within 14 days usually halves it. Challenging in that window normally protects the discount if you are rejected, but confirm it in writing.
What evidence should I send with a code 21 appeal?
A copy of the Penalty Charge Notice. Photographs of the signs and road markings at the exact location.
