A calm, cited answer — not an upsell.
No tabloid theatrics, no paywall. We explain the rules and quietly hand you the letter.
pcnappeal.uk explains UK PCN codes and appeal grounds for informational purposes. Procedural deadlines are time-critical — always check the date on your PCN. This site is not affiliated with TfL, London Councils, any local authority, the Traffic Penalty Tribunal or London Tribunals. For complex or contested appeals, consult Citizens Advice or a qualified solicitor.
How it works
Four calm steps, start to finish
From the code on your notice to a letter in your hand — each step cited, each deadline flagged.
Step 1
Find your code
Every council PCN carries a contravention code. Look it up to see what it means in plain English and which penalty band it sits in.
Step 2
See the grounds
We show the statutory grounds for appeal that most often apply to that code — each quoted from the regulations, with what evidence supports it.
Step 3
Mind the deadlines
The deadline ladder shows the 14-day discount, the formal-representation window, and the appeal stage — and what happens if you miss each one.
Step 4
Draft your letter
Build a representations letter in your browser, copy it, and send it yourself. Nothing is logged, and we never charge for it.
