Parking Fine but Machine Was Broken — How to Appeal
Last updated: February 2026
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: this is one of the strongest grounds for a successful appeal. Here's exactly how to handle it.
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 can't be expected to pay when the operator hasn't provided a working way to do so.
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:
- Informal challenge to the council (within 14 days for the discount)
- Formal representations if the informal challenge fails
- Traffic Penalty Tribunal (England and Wales) or equivalent if formal representations are rejected
Councils are legally required to maintain their machines. If a machine was broken, they should have either covered it with an "out of order" notice or suspended enforcement in that area. If they didn't, your appeal is very strong.
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:
- Appeal to the operator directly
- POPLA (if the operator is a BPA member) or IAS (if the operator is an IPC member)
Private operators have a duty to provide a functioning payment method. If they failed, they can't charge you for not paying.
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 their maintenance logs — they're required to keep records of machine faults
- 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, you haven't committed a contravention — you simply couldn't comply. Most councils will cancel the charge if you can demonstrate the machine was faulty.
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
Template Appeal Letter
Dear [OPERATOR NAME],
I am writing to appeal [PCN/Parking Charge Notice] reference [YOUR REF], issued at [LOCATION] on [DATE].
On the date in question, I attempted to pay for my parking using the pay-and-display machine at [LOCATION]. The machine was not functioning — [describe the fault: screen was blank / card reader was not responding / machine displayed an error message / coin slot was jammed].
I have attached [photographs/video] showing the machine's condition at [TIME] on the date in question.
[If applicable: There was no alternative payment method available / The signage did not clearly indicate any alternative payment method / I attempted to use the [APP NAME] app but was unable to due to [no phone signal / app error / etc.].]
I was willing and prepared to pay for my parking but was prevented from doing so by the operator's own equipment failure. It is unreasonable to issue a charge in these circumstances.
I request that this charge be cancelled in full.
Yours faithfully,
[YOUR NAME]
What Happens Next
Broken machine appeals have a high success rate, especially when accompanied by photographic or video evidence. For general appeal advice, see our guide on how to appeal a parking ticket in the UK. Most operators will cancel the charge when confronted with clear evidence of a machine fault.
If the operator rejects your appeal (which sometimes happens with automated rejection systems), escalate to POPLA (BPA members) or IAS (IPC members). Adjudicators at POPLA are generally sympathetic to broken machine cases — it's hard to argue that someone who couldn't pay should be charged for not paying.
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
