Westminster PCN — your three dates, and what challenging really does to the discount
Challenging does not automatically cost you the 50%.
Counted the way the regulations count, where the day of service is day 1. Nothing stored, no email asked for.
To pay, use Westminster City Council's own service — it is the cheapest thing on this page and it is free to reach: Pay a Westminster PCN. To challenge it, the council's own challenge page and that costs nothing either. Both read at source Wed, 9 September 2026.
That is the most common belief about a council PCN, and it is not what the regulations say. 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.
The recommendation itself is in the Department for Transport's Statutory guidance for local authorities in England on civil enforcement of parking contraventions, read at source Thu, 20 August 2026: “Where the enforcement authority receives full payment within 14 days of the service of the PCN, it must accept the discounted amount.” and, for a postal camera PCN, “When a penalty charge notice has been served by post using evidence from an approved device, the discount period is 21 days from the date of service of the notice.”
What follows is the part neither of those pages tells you: how the discount is actually counted, what happens to it if you challenge, and what your next four deadlines are.

The statutory clock, from the regulation rather than from 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 notice prints the exact date; where it differs from the one computed above, the notice is the authority. Read at legislation.gov.uk on Wed, 9 September 2026.
How to challenge it, and where a challenge actually goes
A written challenge, free. Send it in writing so there is a record, quote the PCN reference, and attach photographs and any receipt. This is the only challenge the statutory guidance asks the council to consider re-offering the discount after rejecting — and, as above, that is a recommendation to them and not a right you hold.
Formal representations. Once a Notice to Owner is served on the registered keeper, representations must be made within 28 days beginning with the date it was served, on the statutory grounds. Free, at the full charge. A postal camera PCN skips this stage and takes representations directly.
An independent adjudicator, free. A London PCN is heard by London Tribunals (Environment and Traffic Adjudicators); outside London, by the Traffic Penalty Tribunal. 28 days beginning with the date of service of the Notice of Rejection, and the adjudicator may allow longer. The adjudicator's decision binds the council.
What it costs to ignore it
Nothing happens quickly, and then several things happen at once. Past the discount window the charge is payable in full. Past the representations stage the council may serve a Charge Certificate, which increases the penalty by 50%, and then register it as a debt at the Traffic Enforcement Centre — after which an order for recovery and, if that is not answered, enforcement agents' fees can be added on top. Where those notices did not reach you, the TEC witness-statement route (form TE9, with TE7 if you are out of time) exists for exactly that situation. Ignoring a PCN is the one route with no free stage in it.
What Westminster City Council itself publishes
Every line in this section comes from Westminster City Council's own website, with the address it came from and the day we read it. Nothing here is summarised from anywhere else, and nothing is a figure we worked out. The lines in quotation marks are quotations, word for word. One line is not — it is a list, an address or a charges table set as prose by us, and it says so underneath.
“A 50% discount applies if you pay within 14 days of service (or 21 days for a CCTV parking PCN received through the post).”
— quoted from Westminster City Council, its own website, read at source Wed, 9 September 2026.
“Pay” there means pay the Penalty Charge Notice; the page is Westminster's own payment page and the sentence is about that PCN.
“We will consider any written challenge submitted against the issue of a penalty charge notice (PCN) up until the issue of a charge certificate.”
— quoted from Westminster City Council, its own website, read at source Wed, 9 September 2026.
A PCN will be cancelled upon challenge if: we are satisfied that a valid concession or exemption to park applied; the PCN was issued in error; if there is strong mitigation for the cancellation of the PCN, such as if the PCN was incurred in circumstances beyond the reasonable control of the motorist.
— transcribed from Westminster City Council's own page — the page it is on, read at source Wed, 9 September 2026.
“Unlike criminal law where the standard of proof is 'beyond a reasonable doubt', civil law is based on the 'balance of probabilities'.”
— quoted from Westminster City Council, its own website, read at source Wed, 9 September 2026.
“We are aware of fraudulent text messages claiming to be from the London Borough of Westminster. These messages ask for payment of an outstanding Penalty Charge Notice (PCN) before a Notice to Owner is to be been issued.”
— quoted from Westminster City Council, its own website, read at source Wed, 9 September 2026.
What this page does not tell you, and why
We publish what we have read at source and nothing else. These are the things we looked for on Westminster City Council's own website and did not find, written down rather than filled in:
- Westminster's own penalty amounts (Band A / Band B, higher and lower level) — we could not reach a Westminster-hosted page publishing them on 9 September 2026, so no amount is printed here. The amount on your own notice is the authority.
- A postal address for written challenges — Westminster's challenge page routes to an online form and publishes no postal address for representations.
Council PCN or private parking charge? The routes never touch
The words on the paper decide. “Penalty Charge Notice” is a statutory penalty from a council or TfL — this page. “Parking Charge Notice” is a private company's invoice, appealed to the operator and then to POPLA or the IAS: look the operator up among the 217 we hold, or use the private parking deadline calculator.
