Points to check before you pay

  • Were both no entry signs present and visible? Check exemption plates (e.g. "except cycles", 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 51 PCN?

In London bus lane and moving traffic PCNs are £160, halved if paid within the discount period on the PCN (London Councils says 21 days for CCTV PCNs; some boroughs state 14) (London Councils). Outside London councils set the charge within the national bands, and the discount is 50% if paid within 21 days of a camera PCN being served (SI 2022/71).
