Methodology
How honest are these win rates?
Our methodology, our sources, our limitations — and why we tell you when not to fight.
What we estimate
When you enter your ticket details and answer our triage questions, GetRighted produces a verdict: Strong, Workable, Weak, or Pay-the-discount. Each verdict comes with an estimated win probability.
These are estimates, not guarantees. No one can predict the outcome of an individual appeal with certainty. What we can do is tell you, based on the available evidence, whether your case has the structural features that tend to win.
Where the numbers come from
Our estimates are built from three sources:
What we adjust for
The base win rate for each defense ground is adjusted for:
- Trade body — BPA (POPLA) cases score higher than IPC (IAS) cases for the same defense, because POPLA is independent and IAS is not.
- Evidence strength — if your answers indicate you have strong evidence (photos of signage, payment receipts, PCN showing wrong vehicle details), the estimate adjusts upward.
- Defense confidence— a definitive answer ("the signage was not visible") scores higher than an uncertain one ("I'm not sure").
What we do NOT adjust for (yet)
Honesty requires listing our limitations:
- Individual assessor variation — POPLA assessors vary in how they weight certain arguments. We cannot predict which assessor will handle your case.
- Operator-specific rejection patterns — we are building a database of how each operator responds to specific defense grounds, but this is early-stage data.
- Site-specific signage changes — operators sometimes improve signage after losing appeals. Our data may not reflect very recent changes.
- Calibration against our own outcomes — as more users report their results, our estimates will become calibrated against real-world win rates rather than a priori analysis. We are transparent that early estimates are analytical, not empirical.
Why we tell you to pay
For many tickets, the honest answer is: pay the discounted rate and move on. If your ticket was correctly issued and you have no technical defense, fighting it wastes your time and risks the charge increasing.
We do not charge for this advice. The triage verdict is always free. Telling people not to fight when they can't win is not a business failure — it is the reason people trust us.
We will never tell you a case is strong when it is not. If that means fewer paying customers, that is a trade-off we accept.
What GetRighted is — and is not
Scope boundaries
GetRighted covers private parking charges (BPA and IPC operators) and council penalty charge notices. We do not cover:
- Police fixed penalty notices (these go to Magistrates' Court — seek legal advice)
- Court-stage disputes (if your case reaches county court, consult a solicitor)
- Speeding tickets, bus lane PCNs, or moving traffic offences (planned for a future release)
- Personal injury, employment, or family law matters
If your case falls outside our scope, we will tell you clearly and refer you to the appropriate service (Citizens Advice, a local solicitor, or the relevant ombudsman).
