How to appeal a Horizon Parking parking charge
Your three steps
- Appeal to Horizon Parking within 28 days through its portal, with your charge reference, registration and evidence. Save the confirmation. Horizon portal
- If rejected, appeal to POPLA with the rejection letter's verification code, normally within 28 days. Send your grounds and evidence together. POPLA instructions
- Keep a cancellation confirmation. If the charge is upheld, check the payment deadline. Respond to any later court claim. Court guidance
Read whether Horizon alleges an overstay, non-payment or failure to register your vehicle. A purchase receipt and a parking payment prove different things; match your evidence to the allegation. Horizon charge details
Grounds to check against your notice
Use the points that match what happened and attach evidence. These are grounds to investigate, not a promise that an appeal will be accepted.
The registration entered contained a typo
Supply the payment or validation record and the number entered. Identify the error and ask Horizon to apply the keying-error provisions. Single Code, Annex F
The postal notice does not establish keeper liability
In England and Wales, check Schedule 4 conditions. If no windscreen notice was issued, the postal notice must be delivered within 14 days for keeper liability. That issue is separate from what the driver owes. Schedule 4, paragraph 9
The signs or recorded times do not support the charge
Photograph the restriction at the entrance and near your bay. Compare the allowed stay with the recorded times and check any applicable grace period; explain the particular mismatch. Single Code, consideration and grace periods
Evidence to collect before you appeal
- Notice and envelope showing issue and delivery dates.
- Timed shopping receipt and parking or validation confirmation.
- A photo of any faulty registration tablet and witness details.
- Entrance signs, parking terms and camera timestamps.
What the published POPLA outcomes show
Horizon Parking · 2024/25 · 2,668 assessor decisions.
Assessor decisions in the driver's favour
12.9%
Allowed appeals divided by allowed plus refused appeals. Withdrawals are excluded.
343 allowed / 2,668 decided.
Favourable outcomes: upper bound
≤ 45.0%
Allowed appeals plus all not-contested cases, divided by decided plus not-contested cases. This is a ceiling, not the measured favourable share: some withdrawals are by drivers, not operators.
(343 allowed + 1,559 combined withdrawals) / 4,227 completed.
The appendix does not split operator and driver withdrawals for each operator. The exact share including only operator withdrawals cannot be calculated. Do not treat all not-contested cases as cancellations or apply the service-wide withdrawal split to an operator.
These are historical POPLA second-stage cases, not first-stage appeal outcomes or a forecast for your charge. Read the current route above; a change of association does not turn POPLA figures into IAS figures.

Compare all operators and read the definitionsWhat happens if you ignore it?
Ignoring a private charge can cost you the appeal deadline and early-payment discount. The operator may pursue the debt, including through court. A debt collection letter is not itself a court judgment. If a claim arrives, respond by the deadline: failure to respond can lead to a judgment. A judgment normally stays on the register for six years, but paying it in full within one month removes it. GOV.UK: county court judgments

Where do I find Horizon's photographs?
Use Horizon's notice portal with the charge reference and vehicle registration. Save the charge details and any evidence displayed before preparing your appeal. Source
Can I go straight to POPLA for Horizon?
