Parking Machine Broken? Appeal Evidence, Template & Rights

Last updated: August 2026

Updated August 2026 - 7 min read

Few things feel more unjust than getting a parking charge when you genuinely tried to pay but couldn't because the machine was broken. The parking operator's own equipment failed, and somehow you're the one being punished for it.

The good news: with strong evidence, this can be one of the better appeal grounds. This guide shows what to photograph, what wording to use, and how POPLA, IAS, or a council tribunal may view the issue.

Why This Happens

Pay-and-display machines break. Screens freeze, card readers fail, coin slots jam, receipt printers die. It happens constantly, especially in older car parks where machines are poorly maintained.

The problem is that enforcement doesn't stop when the machine does. ANPR cameras keep recording. Patrol officers keep issuing tickets. The system doesn't care that you couldn't pay — it just sees an unpaid stay.

This applies to both council car parks (where you get a Penalty Charge Notice — see our council PCN appeal guide) and private car parks (where you get a Parking Charge Notice). The appeal process is different for each, but the underlying argument is the same: you should not be penalised when you made a genuine attempt to pay and the operator did not provide a working route.

Council Car Parks vs. Private Car Parks

Council PCN (Penalty Charge Notice)

If the car park is run by the council, you'll receive an actual fine — a Penalty Charge Notice. The appeal process goes:

1. Informal challenge to the council (within 14 days for the discount)
2. Formal representations if the informal challenge fails
3. Traffic Penalty Tribunal (England and Wales) or equivalent if formal representations are rejected

Councils are expected to maintain their machines and explain any alternative payment routes clearly. If a machine was broken and there was no reasonable alternative way to pay, your appeal is much stronger, especially with dated photos or video.

Private Car Park (Parking Charge Notice)

If the car park is run by a private company (ParkingEye, APCOA, NCP, etc.), you'll receive an invoice. The appeal process goes:

1. Appeal to the operator directly
2. POPLA (if the operator is a BPA member) or IAS (if the operator is an IPC member)

Private operators should provide a reasonable, accessible payment route. If their equipment failed and no clear alternative was available, argue that you were prevented from complying with the displayed terms.

The Evidence You Need

Evidence is everything with a broken machine appeal. Without it, it's your word against theirs — and they'll claim the machine was working fine. Here's what to gather:

At the Time (If You Haven't Left Yet)

• Photograph the machine — capture any error messages, blank screens, or "out of order" notices
• Photograph the screen up close — if it's frozen or displaying an error
• Video the machine — show yourself trying to use it and failing
• Note the time — your phone's timestamp on photos will help
• Ask other people — if others are also struggling with the machine, get their names and contact details as witnesses
• Leave a note — put a note on your dashboard saying "Machine broken — attempted to pay at [TIME]" and photograph it
• Try to pay by phone/app — if there's an alternative payment method listed, try it. Screenshot any failures. If you succeed in paying by an alternative method, keep proof

After the Fact

If you've already left and don't have photos, all is not lost:

• Check if anyone else posted about the broken machine online (local Facebook groups, Google reviews of the car park)
• Contact the car park operator and ask for maintenance or fault logs for the machine
• If it's a council car park, submit a Freedom of Information request for machine fault logs on the relevant date
• Ask the operator how many other charges were issued at the same time — a spike in charges suggests a system failure

The Legal Argument

For Council PCNs

Under the Traffic Management Act 2004, councils can only issue PCNs where a contravention has occurred. If the machine was broken and no alternative payment method was available, argue that you could not comply despite trying. Councils and tribunals are more likely to take this seriously when you have dated photos, video, or fault-report evidence.

For Private Parking Charges

Private parking charges are based on contract law. For a contract to be enforceable, both parties must be able to perform their obligations. If the operator's obligation was to provide a working payment method and they failed, you can argue:

• No contract was breached — you attempted to comply but the operator's equipment prevented it
• The operator failed to mitigate — they should have either fixed the machine, provided an alternative, or suspended enforcement
• Unfair Commercial Practice — charging someone who couldn't pay because of your own equipment failure is arguably an unfair commercial practice under the Consumer Protection from Unfair Trading Regulations 2008

"But There Was an App..."

This is the most common counter-argument you'll face. The operator will say "you could have paid by app" or "there was an alternative payment method."

Here's how to handle this:

• Was the app clearly advertised? If the signage only mentioned the machine and the app was in small print or not mentioned at all, you had no reasonable way of knowing about it
• Did you have phone signal? Many car parks (especially underground or in rural areas) have poor phone signal. No signal means no app
• Did the app work? If you tried the app and it didn't work either, screenshot the error
• Do you need a smartphone? Not everyone has one. If the only alternative to the broken machine required a smartphone, that's not a reasonable alternative for all motorists
• Was downloading an app reasonable? Expecting someone to download, register for, and set up a new app on the spot — while their parking time is ticking — is not a reasonable expectation

What Happens Next

Broken machine appeals are much stronger when accompanied by photographic or video evidence. For general appeal advice, see our guide on how to appeal a parking ticket in the UK. Some operators cancel when confronted with clear evidence of a machine fault, but you should be ready to escalate if they reject it.

If the operator rejects your appeal, escalate to POPLA (BPA members) or IAS (IPC members) where available. For operator-specific routes, see our guides to APCOA appeals, NCP appeals, and ParkingEye appeals. Your strongest point is evidence that you tried to pay, no reasonable alternative was available, and the charge resulted from the operator's own payment failure.

Preventing This in Future

• Always photograph a broken machine before you leave
• Try any alternative payment method listed on signage
• Leave a note on your dashboard and photograph it
• If possible, report the fault to the operator before you leave (call the number on the machine)
• Keep the dashcam running — it captures timestamps automatically

Summary

• A broken machine is one of the strongest grounds for appeal
• Evidence is everything — photograph or video the broken machine
• You have a stronger appeal if the operator's own equipment prevented payment
• Counter the "there was an app" argument with evidence about visibility, signal, and accessibility
• This works for both council PCNs and private parking charges
• Escalate to POPLA/IAS/Traffic Penalty Tribunal if the operator rejects your appeal
