Points to check before you pay
Was the engine actually running?
If one of these applies, the usual statutory ground is that the contravention did not occur. Other grounds (not the owner, stolen vehicle, already paid, wrong amount, procedural impropriety) apply whatever the code. The checker shows which fit your case.
How much is a code 63 PCN?
Outside London, councils charge lower level contraventions at £40 or £50 depending on their band, halved if paid early (SI 2022/71, Sch 3). In London it is £110 (Band A) or £90 (Band B) from 7 April 2025 (London Councils). Wales sets its own levels: check your PCN.
Questions
What does PCN code 63 mean?
Parked with engine running where prohibited. Leaving the engine idling where an order bans it.
Is code 63 a higher or lower level contravention?
It is a lower level parking contravention, so it is charged at the council's lower rate.
