Contravention code 40 is a parking contravention, enforced by civil enforcement officers. If you have received this PCN from Camden, Parking Mate AI can check it for defects and prepare a challenge letter for London Tribunals.

Contravention code 40 means: Parked in a designated disabled person's parking place without displaying a valid disabled person's badge in the prescribed manner. This is a parking contravention issued under the Civil Enforcement of Road Traffic Contraventions (General Provisions) Regulations 2022. Camden enforces this via civil enforcement officers on the street.
You have received a penalty charge notice from Camden with contravention code 40. In plain English, this means the council considers that you parked in a designated disabled person's parking place without displaying a valid disabled person's badge in the prescribed manner.
The legal basis for this PCN is the parking enforcement scheme, backed by a traffic regulation order (TRO or TMO) that Camden must have properly made and signed. Without a valid order and compliant signage, the restriction is not enforceable.
To challenge this PCN, you can make formal representations to Camden. If the council rejects your representations, you have the right to appeal to London Tribunals. The adjudicator's decision is independent and binding on the council.

No. A Camden code 40 PCN may be incorrectly issued for several reasons: the signage may not comply with regulations, the observation period may not have been followed correctly, the TRO may be defective, or the code may not match what actually happened.
Ignoring a Camden code 40 PCN leads to escalation: notice to owner, then a charge certificate (increasing the penalty by 50%), then registration at the Traffic Enforcement Centre, and eventually bailiff enforcement. Responding early preserves the most options.
