Private Parking Fine Appeal: POPLA, IAS Rules Explained

A parking charge on private land, such as a supermarket or retail car park, is a contractual charge rather than a council fine. You can appeal it for free, first to the operator, then to an independent adjudicator, before paying anything.

Private parking charges vs council PCNs

A charge issued on private land, such as a supermarket, retail park, hospital or airport car park, works differently from a council Penalty Charge Notice (PCN). A council PCN is a statutory civil penalty issued under specific legislation for a parking contravention on the public highway or council-controlled land. A private parking charge is not a fine at all in the legal sense. It's a contractual charge, based on the idea that by parking on the land you accepted the terms displayed on the signage, and the charge is what the operator says you owe for breaching them.

That distinction matters because it changes which rules, which appeals body, and which regulator applies. If your notice came from a council, or refers to a civil enforcement officer and a right of appeal to a tribunal, see our separate guide to appealing a council PCN instead. This page covers charges from private operators on private land.

Who can issue a private parking charge, and how they trace you

Reputable private parking operators are members of one of two accredited trade associations: the British Parking Association (BPA) or the International Parking Community (IPC). This membership matters for a practical reason. To get your name and address from the DVLA using only your vehicle registration, an operator must belong to an accredited trade association operating under the DVLA's data-release framework. An operator with no such accreditation has no lawful route to your details through the DVLA.

Separately, the Protection of Freedoms Act 2012 sets out the conditions an operator must meet to pursue the registered keeper, rather than only the driver, for a parking charge. This includes serving a compliant notice within strict time limits and using the wording set out in Schedule 4 of the Act. If an operator's notice is late, incorrectly worded, or otherwise falls short of these conditions, keeper liability may not have transferred at all, which is itself a valid ground of appeal, separate from any argument about the parking itself.

Grounds to appeal a private parking charge

There is no fixed list of acceptable grounds, but appeals commonly succeed on one or more of the following:

• Signage. The terms, the charge amount, and the fact that a charge could apply were not clearly and prominently displayed where you could reasonably be expected to see them before parking.
• Grace period. The operator didn't allow the grace period required by the Code, either to decide whether to stay after arriving or to leave after your session ended.
• Genuine mistake. For example, a payment was made but not correctly registered, a vehicle registration was mistyped in a pay-and-display machine or app, or a machine or app malfunctioned.
• Disproportionate charge. The amount demanded is out of proportion to any loss the landowner actually suffered from the contravention.
• Keeper liability not established. The operator failed to meet the Protection of Freedoms Act 2012 conditions needed to pursue the registered keeper rather than the driver.
• Permission to park. You had a valid permit, blue badge, pre-booking, or other authorisation that the operator failed to account for.

Not every case fits neatly into one of these, and a genuinely disputed case with money at stake, especially one heading toward county court, is a matter for a solicitor rather than general guidance.

How to appeal, step by step

1. Identify the operator and its scheme. Check the charge notice for the operator's name, then confirm whether they're a BPA or IPC member. This tells you whether an unsuccessful appeal would go to POPLA or the IAS.
2. Gather your evidence. Date-stamped photos of the signage (including any that was missing, obscured, or hard to read), your payment receipt or app confirmation, any relevant permit, and a note of your actual arrival and departure times.
3. Appeal to the operator first, in writing. This is free and is usually required before you can escalate. Set out your grounds clearly, attach your evidence, and keep a copy of everything you send.
4. Escalate to the independent appeals service if rejected. Use the POPLA or IAS reference code the operator is required to give you when it turns down your appeal. This stage is also free and is decided by an adjudicator independent of the operator.
5. Wait for the decision. It's binding on the operator: if you win, they cannot pursue the charge further. It isn't binding on you, so if you lose you still keep other options, though further action from the operator at that point would usually mean the county court.
6. Don't ignore the charge while a genuine appeal is open. You're not required to pay while your appeal or independent review is in progress, but keep records of every step in case the operator disputes that you appealed at all.

The Single Code of Practice: the original protections and the 2025 camera amendment

A new industry-wide Single Code of Practice was published jointly by the BPA and the IPC on 27 June 2024, overseen by the newly created Private Parking Scrutiny and Advice Panel. It took effect for new car parks from 1 October 2024 and introduced several changes designed to standardise how private parking charges are set and enforced:

• A £100 cap on most parking charges, with only a small number of specific situations falling outside the general cap.
• A minimum 40% discount for paying within 14 days of the charge being issued.
• A mandatory grace period, requiring operators to give drivers reasonable time both to decide whether to stay after arriving and to leave once their session has ended.
• A £70 cap on debt-recovery and escalation fees added if a charge goes unpaid. The government questioned this cap in 2025 and it may change, so treat it as under review rather than fixed, but it has not been scrapped.

Existing sites were given until 31 December 2026 to become fully compliant with the Code.

A later amendment, version 1.1 of the Code, took effect on 17 February 2025. It is narrower in scope than the original Code and focuses on car parks managed by camera or automatic number plate recognition (ANPR) systems: at those sites, operators must not add a late-payment charge if the driver pays in full before leaving, and enforcement is carried out by post rather than by a ticket placed on the windscreen.

It's worth being precise about what "the Code" means here, because there are two. The one described above is an industry code, produced by the trade bodies themselves. There is a separate government statutory code of practice, provided for under the Parking (Code of Practice) Act 2019, which would have put a single set of rules on a legal footing overseen by a government-appointed regulator. That statutory code was laid before Parliament in February 2022 but withdrawn in June 2022, pending a review of proposed charge and fee levels, and it still hasn't come into force. The Government consulted on a replacement statutory code in 2025 and has said it intends to publish a new Private Parking Code of Practice in autumn 2026, so this page is worth revisiting once that happens. So as things stand, the rules actually binding on operators today are the industry Single Code of Practice, not a statutory one.

What POPLA and the IAS actually decide

POPLA (Parking on Private Land Appeals) is the free, independent appeals service for parking charges issued by BPA members. The IAS (Independent Appeals Service) plays the equivalent role for IPC members. Both work the same basic way: once the operator has rejected your initial appeal, you have a limited window to escalate to whichever service applies, submit your evidence, and receive a decision from an adjudicator who has no relationship with the operator.

Their decision resolves the dispute from the operator's side. A decision in your favour means the operator must cancel the charge and cannot pursue it again. A decision against you doesn't compel you to pay on the spot, but it does mean the informal appeals route has been exhausted, and if the operator pursues the charge further, the next stage would ordinarily be the county court rather than another round of appeal.
