PCN Code 90: Re-Parked Within the No Return Period — How to Fight Back

You've done everything right. You paid for your parking, left the car park, ran your errands, and came back a couple of hours later to park again. Straightforward, right? Then a Penalty Charge Notice drops through your letterbox — or worse, you find one tucked under your wiper — and suddenly you're staring down a fine for something that felt completely harmless.

Welcome to PCN Code 90: re-parked in a car park before the no return period has expired. It catches thousands of drivers off guard every year, and it's one of the more misunderstood contraventions in off-street parking enforcement. But here's the thing — it's also one of the more challengeable ones, if you know what to look for.

What Is PCN Code 90, Exactly?

PCN Code 90 is an off-street contravention, meaning it applies to council-operated car parks rather than the public highway. It's issued under the Traffic Management Act 2004, which gave local authorities in England and Wales the power to enforce civil parking contraventions in off-street locations.

The contravention occurs when a driver parks in a car park, leaves, and then returns and parks again before a specified "no return" interval has passed. That interval is set by the council and is typically one hour, though some car parks impose two-hour restrictions.

The logic behind the rule is sound — councils use no return periods to prevent the same driver from monopolising a space by repeatedly paying for short sessions. But in practice, the rule snares plenty of legitimate drivers who simply didn't notice the signage, or who returned to the same car park by coincidence rather than design.

How Is It Enforced?

Councils use two main methods to catch Code 90 contraventions:

• ANPR cameras (Automatic Number Plate Recognition): The most common method in modern car parks. Cameras log your vehicle's number plate on entry and exit. If your plate reappears within the no return window, the system flags it automatically.
• Civil Enforcement Officer (CEO) observations: A parking warden physically observes a vehicle leaving and returning within the prohibited period. This is less common in large car parks but still occurs in smaller or unstaffed sites.

The ANPR route is where things can get interesting from an appeal perspective — and we'll come back to that.

The No Return Period Must Be Clearly Signposted

This is the single most important point when it comes to challenging a Code 90 PCN: the no return period restriction must be clearly, prominently, and unambiguously displayed at the car park entrance and ideally throughout the site.

Under the Local Authorities' Traffic Orders (Procedure) (England and Wales) Regulations 1996 and associated guidance, councils must make their traffic regulation orders properly and ensure drivers have a reasonable opportunity to understand the restrictions that apply.

If the signage is:

• Faded, damaged, or obscured
• Positioned where it's genuinely easy to miss on entry
• Ambiguous about which bays or zones the restriction applies to
• Missing entirely from a secondary entrance you used

...then you have a credible grounds for appeal.

Pro tip: Go back to the car park as soon as possible after receiving the PCN. Take clear, timestamped photographs of every entrance sign, paying particular attention to the size, condition, and visibility of any no return period notices. Do this before the council has any chance to update the signage.

What the Council Must Prove

When you challenge a Code 90 PCN, the burden of proof sits with the council. They need to demonstrate:

1. A valid Traffic Regulation Order (TRO) exists that establishes the no return period for that specific car park
2. Adequate signage was in place at the time of the alleged contravention
3. Evidence of the contravention itself — typically ANPR entry/exit logs or a CEO's observation record
4. That the correct procedure was followed in issuing the PCN

If any of these elements are weak or missing, your appeal has real traction.

Common Grounds for Appeal

Here are the most effective arguments drivers use successfully against Code 90 PCNs:

1. Inadequate or Missing Signage

As covered above, if you genuinely couldn't have been expected to see or understand the no return restriction, this is your strongest card. Be specific — describe exactly which entrance you used, what you saw (or didn't see), and back it up with photographs.

2. ANPR Error or Misread

ANPR systems aren't infallible. Partial plate reads, similar-looking plates, or technical glitches can result in wrongly attributed contraventions. If you have any reason to believe the system confused your vehicle with another, request the full ANPR evidence log from the council. They're obliged to provide it.

3. You Were in a Different Part of the Car Park

Some large sites contain multiple distinct areas with separate entrances and different TROs. If you parked in bay A, left, and returned to bay B — which operates under different or no restrictions — the PCN may not be valid. Check the TRO carefully.

4. Exceptional Circumstances

Did you return because of a medical emergency, a vehicle breakdown, or another genuine emergency? Councils have discretion to cancel PCNs on compassionate grounds, particularly at the informal stage. Document everything — medical notes, breakdown receipts, or witness statements all help.

5. The No Return Period Had Actually Expired

ANPR timestamps can occasionally be inaccurate, or there may be a dispute about the exact timing. If you have any evidence — a parking receipt, a bank transaction timestamp, CCTV footage — that shows you returned after the restriction window had closed, use it.

The Appeals Process: Step by Step

Step 1: Informal Challenge

You have 28 days from the date of the PCN to make an informal challenge. Do this in writing (email is fine for most councils) and be clear, concise, and factual. Attach your photographic evidence. If successful, the PCN is cancelled. If rejected, you'll receive a Notice to Owner (NTO) and move to the next stage.

Pro tip: Don't ignore the PCN hoping it'll go away. Failure to respond escalates the fine — typically from a 50% discounted rate (if paid within 14 days) to the full penalty, and eventually to a debt recovery stage.

Step 2: Formal Representations

Once you receive the NTO, you have 28 days to make formal representations. This is a more structured process — your grounds must fit within the statutory grounds set out in the TMA 2004. These include:

• The contravention did not occur
• The PCN was issued outside the relevant TRO
• The TRO itself is invalid
• You were not the owner of the vehicle at the relevant time
• The vehicle was taken without your consent

Submit your representations with all supporting evidence attached.

Step 3: Independent Tribunal Appeal

If formal representations are rejected, you'll receive a Notice of Rejection and the right to appeal to an independent adjudicator. In London, that's London Tribunals. Outside London, it's the Traffic Penalty Tribunal (TPT).

These tribunals are genuinely independent and regularly overturn council decisions — particularly where signage is poor or procedural errors have occurred. The process is mostly conducted online or by written submission, and there's no fee to appeal.

What Evidence to Gather Right Now

If you've just received a Code 90 PCN, act quickly and collect the following:

• Photographs of all car park entrances and no return period signs (with timestamps)
• Your parking receipts or payment app records showing your sessions
• Bank or card statements confirming payment times
• Any CCTV or dashcam footage from the relevant period
• A copy of the Traffic Regulation Order (request this from the council — they must provide it)
• The full ANPR log if cameras were used (request this formally)

Your Actionable Next Steps

1. Don't ignore the PCN — respond within 28 days to preserve your appeal rights and the discounted payment option
2. Return to the car park immediately and photograph all signage thoroughly
3. Request the evidence pack from the council, including the TRO and ANPR data
4. Draft your informal challenge focusing on signage adequacy, ANPR accuracy, or the specific circumstances of your return
5. Escalate to formal representations if the informal challenge fails — don't be put off by an initial rejection
6. Take it to tribunal if needed — adjudicators regularly side with drivers on Code 90 cases where councils can't demonstrate clear, visible signage

A PCN Code 90 might feel like a done deal when it lands in your hand, but it's far from it. Councils must earn every penalty they issue — and when they can't prove the restriction was properly communicated, the fine simply shouldn't stand.
