First, check which body your charge goes to
Private parking operators in Britain belong to one of two trade associations, and that decides where your appeal goes:
- British Parking Association (BPA) members → POPLA
- International Parking Community (IPC) members → the IAS, this page
You do not have to guess. When the operator rejects your appeal it has to tell you which service to use, and the rejection letter will name it. Sending an appeal to the wrong body simply wastes the clock, and the clock is short.
Appeal to the operator first. The IAS cannot look at your case until the company that issued the charge has considered your appeal and rejected it in writing. There is no way to skip that step, so start there and keep a copy of everything you send.
The two routes, and why the difference matters
This is the part that is worth reading twice, because the two routes are not simply "on time" and "late". They give you different rights.
| Standard appeal | Non-standard appeal | |
|---|---|---|
| Deadline | Within 28 days of the operator rejecting your appeal | Up to 12 months from the date the charge was issued |
| Cost to you | Free | £15, non-refundable even if you win |
| Who the decision binds | The operator only. Lose, and you still keep every argument you had | Both you and the operator |
The catch nobody puts in the headline. A free standard appeal is one-way: if the assessor sides with the operator, nothing has been decided against you. The company still has to sue you in the county court and prove its case there, with all your arguments intact. A paid non-standard appeal binds you too, so a decision against you closes the door. Fifteen pounds is not the real cost of the late route — the right to have the charge tested properly is.
Which is a long way of saying: get your appeal in inside the 28 days. Diarise the date the moment the rejection lands.
Put everything in the first time
The IAS is explicit that its decision cannot be reviewed later, so an appeal is not a conversation you can add to. Send the complete case at once: photographs of the signs and of where the car actually was, your payment evidence or permit, any correspondence with the operator, and the reasons the charge should not stand. If you are appealing as the registered keeper rather than the driver, say so plainly and do not volunteer who was driving — you are usually under no obligation to name them.
Grounds that carry weight
The arguments that work here are much the same as at POPLA, because the underlying law is the same:
- Keeper liability was never established. To pursue you as keeper rather than driver, the operator has to follow Schedule 4 of the Protection of Freedoms Act 2012 to the letter, including strict timing and wording. Many notices do not.
- No contract was formed. Signs that were unlit, obscured, too high, too small or absent cannot bind you to terms you were never shown.
- No authority from the landowner. The operator must actually have the right to issue and enforce charges on that land.
- You had paid or held a valid permit. A keying error in a registration is the classic example, and a charge that ignores an obvious typo is worth challenging.
- Grace periods were not honoured. Reasonable time to read the terms on arrival, and to leave afterwards.
For the detail on each of these, the POPLA guide goes through them at length, and the reasoning transfers directly.
If the IAS says no
After a free standard appeal, a decision against you is not a debt and not a judgment. The operator's only route is the county court, where it has to prove the contract, the signage and its authority all over again. Read what actually happens if a parking company takes you to court before you decide to pay, and what ignoring it really means — the honest answer is that ignoring a private charge is riskier than people on forums suggest, but far less final than the letters imply.
Frequently asked
What is the IAS?
The Independent Appeals Service (IAS) is the free, independent appeals body for private parking charges issued by operators who belong to the International Parking Community (IPC). It is a certified alternative dispute resolution provider. If your operator belongs to the other trade body, the British Parking Association, your appeal goes to POPLA instead. Your rejection letter will tell you which one applies to your charge.
How long do I have to appeal to the IAS?
A standard appeal must be lodged within 28 days of the operator rejecting your own appeal, and it is free. After that you can ask the operator for a "non-standard" appeal up to 12 months from the date the parking charge was issued, but that route costs £15, which is non-refundable even if you win.
Is an IAS decision binding on me?
A standard appeal decision is binding on the operator only, not on you. If you lose, you are not forced to pay, and the operator would still have to take you to the county court and prove its case there. A non-standard appeal is different: it is binding on both you and the operator, so paying the £15 means giving up the right to argue the charge later. That is a significant trade-off, and it is the main reason to appeal inside the free 28-day window if you possibly can.
Do I have to appeal to the parking company first?
Yes. The IAS cannot accept an appeal until the operator that issued the charge has considered it and rejected it. Appeal to the operator first, keep a copy of everything, and wait for the written rejection before going to the IAS.
Deadlines, fees and the binding effect of each route are as published by the Independent Appeals Service, checked 1 August 2026. The IAS is the appeals body for International Parking Community members; British Parking Association members use POPLA. This is information, not legal advice, and every case turns on its own facts.
