Why most parking ticket appeals fail (and what actually wins)

Most people appeal a parking ticket the same way: they explain themselves. "I was only five minutes late." "I couldn't find a working machine." "My mum was in hospital." It feels like the fair thing to say — and it almost always loses.

The reason is simple. A private parking charge is a contractual claim, not a question of whether you're a good person or had a rough day. Mitigation — asking for sympathy — doesn't challenge the contract. It concedes it and then asks for mercy, and operators are not in the mercy business. If you want a charge cancelled, you don't appeal to fairness. You appeal to the technical grounds where these tickets are genuinely weak.

Where tickets actually break

• Keeper-liability failures. To pursue you as the registered keeper (rather than the driver), an operator must follow the strict notice rules in the Protection of Freedoms Act 2012 — the right wording, the right information, within the right time windows. Get the paperwork wrong and keeper liability can fall away entirely.
• Inadequate signage. The "contract" only exists if the terms were clearly displayed — legible, well-lit, and prominent enough for a driver to actually see and accept. Poor or hidden signs undermine the whole basis of the charge.
• Grace periods. Codes of practice require a reasonable period to read the signs and decide, and after any free or paid period ends. Tickets issued inside those windows are vulnerable.
• Missing landowner authority. The operator must actually have the right from the landowner to issue and enforce charges there. Sometimes, when challenged, they can't properly show it.

These are the grounds that do the work. They're also exactly the things a driver writing a quick email from their phone doesn't know to raise — which is why so many appeals fail not because the ticket was sound, but because it was challenged on the wrong basis.

The part nobody tells you: it depends who you appeal to

Here's the honest caveat, because it matters more than any single ground. There are two independent appeals services, and your odds are wildly different depending on which one your ticket lands at — and you don't get to choose.

Operators belong to one of two trade bodies. Tickets from the larger body's operators go to POPLA, where 42% of cases end cancelled. Tickets from the other body's operators go to the IAS — and the last time the IAS published its figures, in 2021/22, just 6% of appeals were allowed at adjudication. It has since stopped publishing the number at all.

So the same technical argument that wins comfortably at POPLA can be an uphill battle at the IAS. Anyone promising you a fixed "win rate" is either ignoring this or hoping you don't ask. We won't: which scheme applies depends entirely on who issued your ticket, and part of what we do is tell you honestly where a given ticket stands before you get your hopes up.

What good looks like

A strong appeal identifies the operator, works out which appeals body applies, and builds the case on the technical grounds that actually bite — not on mitigation. That's a specific skill, and doing it well under a deadline is exactly the friction that makes most people give up and pay.

Which is the whole point of Quashed. We read the ticket, pick the grounds that win, draft the appeal, and tell you straight what the odds look like — you just approve it.

IAS/IPC: last published adjudication allow-rate 6% (2021/22); the IAS no longer publishes this figure (per RAC commentary on appeals-data transparency, 2025). Legal grounds reference the Protection of Freedoms Act 2012 and the trade bodies' codes of practice.
