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.

Every common contravention code, in one table

18 codes

Cited to the source

Every code meaning, charge band, ground and deadline traces to legislation.gov.uk, gov.uk, London Councils, or the appeal bodies — with a last-verified date. The full list lives on the Sources page.

Free, and never on your behalf

We publish for free and never charge to write or submit an appeal. The letter builder runs in your browser; you send it yourself. For paid help, we point to Citizens Advice — not to us.

Honest about the unknown

Where an authority doesn't publish a figure, we say so rather than guess. The figures on your own notice always govern.
