“it's really so much easier to just pay it - and quickly,before it doubles.”
— Mumsnet, 10 October 2025
We hold the appeals route for all 217 UK operators. Give this one date and it gives you three.
POPLA code: where it comes from, and the 28 days it starts
Put in the date on your notice. You get your discount deadline, your operator appeal deadline and — the part the general guides get wrong — the right independent appeal window for your operator: 28 days for POPLA, 28 days for the IAS. Paying quickly is often right, and it is often a day earlier than people think: we count the way the regulations count, where the day of service is day 1.

The POPLA code: what it is, where it comes from, and the 28 days it starts
It is a 10-digit verification code, and it is not something you ask POPLA for. The parking operator issues it, with the letter that rejects your appeal:
“You should have received your verification code when you were sent your rejection notice from the parking operator, typically via post or email.”
— POPLA FAQs — verification codes and the appeal window
If the operator will not issue one after rejecting an appeal you made in time, that is a breach of its own trade association’s code of practice, and POPLA says where to take it:
“If a parking operator rejects an appeal you made and you did so within this 28 day window, it is a requirement of the British Parking Association's code of practice that they issue a verification code. If the operator refuses to issue a code in these circumstances you can contact the British Parking Association.”
— POPLA FAQs — verification codes and the appeal window
The code starts the clock this calculator counts: 28 days, and POPLA states it plainly — “You have 28 days to submit your appeal with us from the date the parking operator rejects your appeal.” Put the rejection date into the form above, not the date on the original notice, and it gives you the last day. If your operator is an International Parking Community member the appeal goes to the IAS instead, which issues no code — check which body hears yours, free.
The two independent windows are not the same length
The independent appeal stage is free either way, but the clock is different, and it is set by the trade association your operator belongs to — not by anything you choose. Worked example, both from a notice dated Mon, 2 March 2026 rejected on Fri, 20 March 2026:
| Operator | Association | Appeals to | Window | Deadline |
|---|---|---|---|---|
| 2gether Support Solutions Ltd | BPA | POPLA | 28 days | Fri, 17 April 2026 |
| 3D Parking Ltd | IPC | IAS | 28 days | Fri, 17 April 2026 |
Twelve days separate them. Sending an IAS appeal on POPLA's timetable is the single most common way a free appeal is lost. POPLA or the IAS — the full comparison →
How the deadlines work
Discount period. Pay within this window and most operators reduce the charge, typically by around 40%. Appealing does not extend it, so the discount and the appeal pull against each other — that is the real decision on day one.
Operator appeal. You must appeal to the parking company first. They must consider it and, if they reject it, issue you a code for the independent stage. This appeal is free.
Independent appeal, counted from the rejection code — not from the original notice. POPLA hears appeals against British Parking Association members; the Independent Appeals Service hears appeals against International Parking Community members. Free to you. 105 of the 217 operators we hold route to POPLA and 110 to the IAS.
What it costs if you do nothing
This is the escalation ladder for a private parking charge. Only the first row goes down in price, and only one row costs nothing at all.
| What you do | When | What it costs you |
|---|---|---|
| Pay at the discounted rate | Within 14 days of the notice | The reduced amount — most operators cut the charge by around 40% |
| Appeal to the operator | Usually within 28 days of the notice | Nothing — but the discount window can close while it runs |
| Appeal to the independent service | 28 days (POPLA) or 28 days (IAS) from the rejection code | Nothing. The independent stage is free to the motorist |
| Pay after the discount window closes | After day 14 | The full charge |
| Ignore the reminders | Once the operator passes it on | The full charge plus the operator's debt-recovery costs |
| Ignore a county court claim | If the operator issues proceedings | The charge, the debt-recovery costs and the court fee — and an unanswered claim can end in a judgment against you |
Appealing is the row that costs nothing and closes off none of the others. If the appeal fails you can still pay; if you pay first, the appeal is gone.
Common questions
How long do I have to appeal a parking charge?
Usually 28 days to appeal to the operator, counted from the notice. If they reject you, the free independent appeal is 28 days for a POPLA operator and 28 days for an IAS operator, counted from the rejection code rather than from the original notice.
Is the POPLA deadline the same as the IAS deadline?
Yes — both allow 28 days from the rejection code. What differs is which of the two will hear your appeal, and that depends solely on the trade association your operator belongs to, and it is the most common thing for general guidance to get wrong.
Does appealing stop the discount clock?
No. The discounted amount is usually available for 14 days from the notice, and appealing does not pause or extend it. That is why the calculator shows both dates together — you are choosing between a smaller certain payment and a free appeal.
What if the deadline has already gone?
The free independent appeal is generally lost once the window closes, and nothing brings it back. Two checks survive it, and both are about the operator's dates rather than yours. What is still open after a missed deadline →
Does this tool store my dates?
No. The dates are worked out and shown back to you. There is no account, no email step and nothing to sign up for.
My letter says “Penalty Charge Notice” — is this the right calculator?
No — that is a council (or TfL) ticket on a statutory route with different windows: a 50% discount for 14 days (21 if it came by post from a camera), then formal representations and a free traffic adjudicator. Use the council PCN discount calculator instead →

Questions people ask
These are the questions Google publishes underneath the search this page is written for, measured on 9 and 10 September 2026. Each one is answered here in a sentence, and where we hold no source for an answer the sentence says so instead of guessing.
What does POPLA stand for?
POPLA stands for Parking on Private Land Appeals, the independent appeals service for British Parking Association members, free to the motorist at the point of use.
How many POPLA appeals are successful?
Of the 67,680 POPLA appeals decided in the year to 30 September 2025, 14,578 were successful — 21.5% — and a further 34,502 ended with the operator withdrawing before a ruling.
What is the best way to win a popla appeal?
The best way to win a POPLA appeal is to enter your verification code inside the 28-day window and then answer the operator's evidence pack directly, ground by ground, with dated photographs and receipts of your own.
Is it worth appealing through POPLA?
It is worth appealing through POPLA: the appeal is free, the code in your rejection letter is all you need to start it, and 45.8% of everything POPLA concluded last year ended with the charge cancelled.
The rest of the free tools
Nothing here asks for an email address, and nothing here is a trial.
A council or TfL PCN instead? Different law, different clock, and the council's own free routes are on each page: Westminster · Lambeth · Camden · Islington · TfL · every council page.
Already had a letter from a debt firm? A debt-recovery letter is not a court claim and a court claim is not a judgment — three different things on three different clocks: DCBL · DCB Legal · what each letter actually is.
That is everything the free route gives you, and it is enough to do this yourself tonight. If you would rather read a finished letter than face a blank page: yours is free, on screen and as a download. No payment, no account, no email address.
Build my letter, freeThe one thing on this site you can pay for is one operator’s full POPLA record, £20 once: three years of that company’s appendix rows, the grounds and the clause of its own rulebook that answers each one, its own published route and your clock.
