Points to check before you pay
Check the signs and hours.
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 57 PCN?
Outside London, councils charge higher level contraventions at £60 or £70 depending on their band, halved if paid early (SI 2022/71, Sch 3). In London it is £160 (Band A) or £140 (Band B) from 7 April 2025 (London Councils). Wales sets its own levels: check your PCN.
