“It's worth an appeal regardless because the 14days won't lapse afaik when the appeal is ongoing.”

Challenging does not automatically cost you the 50%.
Council PCN: 14-day discount deadline calculator
Put in the date of service on your Penalty Charge Notice. You get the last day of the 50% discount, the day the full charge starts, and every challenge window after it — counted the way the regulations count, where the day of service is day 1. General guides get that boundary wrong by a day.
Nothing freezes the discount when you challenge. What exists is a recommendation, not a right you hold — and knowing which of the two it is changes what you do today. Statutory guidance asks a council that rejects a challenge made inside the discount period to consider re-offering the 50% for a further 14 days. Councils generally follow it. It is guidance to them and not an entitlement of yours, which is why the date above is the one to work to. We count the boundary the way the regulations count it, where the day of service is day 1. That is the place general guides are out by a day.

How the counting works — from the regulation, not folklore
The discount runs to “the applicable date”, and the regulations define it in one sentence:
““the applicable date” means— (a) in the case of a penalty charge notice served by virtue of regulation 10(2)(a), the last day of the period of 21 days beginning with the date on which the notice is served; (b) in the case of any other notice, the last day of the period of 14 days beginning with the date on which the notice is served.”
— The Civil Enforcement of Road Traffic Contraventions (England) General Regulations 2022 (SI 2022/71) — checked 27/08/2026
“Beginning with the date on which the notice is served” means the day of service is day 1. A PCN served on 2 March reaches day 14 on 15 March — not 16 March. Your PCN prints the exact date; if it differs from the one computed here, the notice is the authority.
Worked examples
| PCN served | How | Discount window | Last day at 50% | Full charge from |
|---|---|---|---|---|
| Mon, 2 March 2026 | Windscreen | 14 days | Sun, 15 March 2026 | Mon, 16 March 2026 |
| Fri, 10 July 2026 | Post (camera) | 21 days | Thu, 30 July 2026 | Fri, 31 July 2026 |
| Sat, 31 January 2026 | Windscreen | 14 days | Fri, 13 February 2026 | Sat, 14 February 2026 |
The same three examples run as automated tests against the code that renders this page, so the table and the calculator cannot drift apart.
The stages, in order
Discount period. Pay and it ends at 50%, by statute — exact, not “up to”. An informal challenge in this window is free, and it is the only challenge the guidance asks the council to re-offer the discount after rejecting.
Notice to Owner. For a windscreen PCN, unpaid past the 28-day payment period, the registered keeper gets an NtO. Formal representations — the challenge with statutory grounds — must be made within 28 days beginning with the date it is served. A postal camera PCN skips this: it takes representations directly.
Independent adjudicator, free. London PCNs go to London Tribunals (Environment and Traffic Adjudicators); everywhere else in England, and Wales, to the Traffic Penalty Tribunal. 28 days beginning with the date of service of the Notice of Rejection, and the adjudicator may allow longer.
Charge Certificate, then court registration. Ignore every stage and the council may serve a Charge Certificate increasing the charge by 50%, then register it as a debt at the Traffic Enforcement Centre — after which bailiff fees can be added. If you never received the earlier notices, the TEC witness-statement route (form TE9, with TE7 if out of time) exists exactly for that; it is free.
Council PCN or private parking charge? The routes never touch
| Council PCN (this page) | Private parking charge | |
|---|---|---|
| Issued by | A council or TfL — it is a statutory penalty | A private company — it is an invoice for alleged breach of contract |
| Discount | Exactly 50%, for 14 days (21 postal), day of service = day 1 | At least 40%, usually for 14 days |
| Independent stage | Traffic adjudicator — free | POPLA or the IAS — 28 days at either, set by the operator's trade body |
| Calculator | You are on it | Private parking deadline calculator → |
The words on the paper decide: “Penalty Charge Notice” = council, this page. “Parking Charge Notice” = private — look the operator up among the 217 we hold to find its appeals body and window, or read the difference explained.
Common questions
When does the 14-day discount on a PCN actually end?
On day 14 counting the date of service as day 1 — so 13 days after the date on the notice, not 14. A PCN served by post on the strength of camera evidence gets 21 days, ending 20 days after service. The regulations call this “the applicable date” and the definition is quoted above.
Does challenging a PCN extend or protect the discount?
Not automatically — nothing freezes the discount when you challenge. Statutory guidance recommends that a council rejecting a challenge made inside the discount period should consider re-offering the 50% for a further 14 days. Councils generally follow it, but it is a recommendation to them, not a right you hold.
What if a Notice to Owner has already arrived?
The discount stage is over, but the strongest stage is just starting: formal representations within 28 days beginning with the date the NtO was served, free, on statutory grounds — and if the council rejects them, a free appeal to an independent adjudicator within 28 days of the rejection.
Is a Penalty Charge Notice the same as a Parking Charge Notice?
No, and the near-identical names are why people lose appeals. A Penalty Charge Notice is a statutory council penalty — this page. A Parking Charge Notice is a private company's invoice, appealed first to the operator and then to POPLA or the IAS — that calculator is here.
