of PCN appeals against Slough Borough Council are won
The Traffic Penalty Tribunal recorded 1,823 outcomes for appeals against Slough Borough Council from 2013/14 to 2024/25, and 1,133 of them ended with the driver paying nothing. That is 7.8 points better than the 54.4% tribunal average.
Over the same period Slough Borough Council told the tribunal it issued 623,299 penalty charge notices. Only 1,823 of them ever reached an adjudicator, roughly one in 342. Almost everyone pays, which is worth knowing before you assume a ticket must be fair because so few people fight it.
What the appeals were about
Slough Borough Council enforces more than one kind of penalty, and drivers do not fare the same on each.
| Penalty type | Outcomes | Not contested | Won |
|---|---|---|---|
| Parking | 1,234 | 451 | 62.6% |
| Bus lane | 589 | 172 | 61.1% |
623 of those 1,133 wins were uncontested. In 55% of the appeals Slough Borough Council lost, it put up no defence at the tribunal at all. Roughly a third to a half of its losses never got argued, so a properly written appeal has a real chance of being conceded before anyone reads the evidence. Those tickets were not close calls. The authority had already given up on them, and the appeal was the only thing standing between the driver and a cancelled charge.
Is it getting easier or harder?
In 2013/14 to 2015/16, drivers won 57.2% of appeals against Slough Borough Council, from 580 outcomes. In 2022/23 to 2024/25 it was 59.5%, from 469. The rate has held broadly steady across the decade.

Busiest year: 2014/15, with 230 appeals decided. A further 28 appeals were closed by consent order across the period, which the tribunal counts separately because it can mean the driver agreeing to pay the original charge.
What this does and does not tell you
These are appeals that reached an independent adjudicator, which is the last stage. They leave out every ticket cancelled earlier, when you first challenge it or make formal representations, and that is where most successful challenges actually end. So your real chance of getting a ticket cancelled somewhere in the process is higher than 62.2%, not lower. Among the 203 authorities in England outside London and in Wales with enough appeals to compare, Slough Borough Council ranks 52nd for how often drivers win.
Two details worth knowing before you read too much into the number. The refused column includes appeals made after the deadline and appeals the driver withdrew, so it is not purely a record of arguments that lost on the evidence. And a small number of appeals each year finish with no outcome recorded against any of these categories, so the totals here are of appeals that reached a recorded outcome rather than of every appeal lodged.
Before you write
- Find your contravention code. Every PCN carries a two digit code that says exactly what they claim you did, and what they have to prove. Look yours up.
- Check the deadline. Discounts and rights both expire. Work out your dates.
- Know how appeals work outside London. The Traffic Penalty Tribunal route, step by step.
- Do not just ignore it. What actually happens if you do.
