Challenge Your Horizon
Parking Charge Notice
Horizon Parking runs car parks across the UK, many of them enforced by cameras. Camera enforcement means notices produced from templates and posted in batches, which is where Schedule 4 errors turn up. We check yours and appeal for £14.99 on a best-effort basis.

Paying a Horizon charge closes it for good. A notice that was given late, or that leaves out something Schedule 4 requires, was never one you owed as the registered keeper, discount or not.
- · The matter is closed immediately
- · You cannot later challenge the charge
- · No refund if the notice turns out to be defective
- · Free, and the two checkers below do the legal analysis for you
- · You draft and submit the appeal letter yourself
- · Worth doing if you have the time and want to word it yourself
- · Was the notice served in time?
- · Does it say what the law requires?
- · Free either way. If you would rather we write and submit it, that's £14.99 - best effort on this operator, so the fee is non-refundable
The right to appeal does not expire with the discount window. A defective notice is defective whether you spotted it on day 3 or day 30.
A Horizon charge is a bill from a private company, sent to you because the DVLA told Horizon who the car is registered to. It does not know who was driving, and its own appeal form asks you to tell it. You do not have to.
Horizon can only make you, the registered keeper, pay if its notice reached you in time and says everything the law lists. That is a test of Horizon's paperwork, not of you, and it is where most keeper appeals are won.
How to appeal a Horizon charge yourself
Horizon's own process, checked against its website in October 2026. You can do all of this without us.
- Where: the appeal form on Horizon's website, or by post to Appeals Department, Horizon Parking Ltd, Finitor House, 2 Hanbury Road, Chelmsford, Essex CM1 3AE. Horizon does not decide appeals over the phone.
- What to include: the Parking Charge reference, the vehicle registration, your name and address, and any supporting evidence. Horizon asks for the driver's name if different; you are not obliged to give it.
- When: within 28 days of the charge being issued.
- While you wait: Horizon says the amount payable is frozen at the rate when you appealed, and that you will hear the outcome in writing within 28 days.
- What to say: appeal as the keeper. Lead with what the paperwork shows: whether the date printed on the notice was in time and whether the wording is complete.
- If Horizon says no: you can ask POPLA for an independent review within 28 days of the decision. It is free, and if you ask, we prepare and submit it for you at no extra cost.
Four things to know before you write to Horizon
Horizon's correspondence rules ask for the driver's name if it was not you. That request is not a legal duty. Keeper liability exists precisely so an operator can pursue the keeper without knowing the driver, and only if it follows Schedule 4. Name the driver and that whole test falls away.
Horizon says the amount is frozen at whatever rate applied when you appealed. So an appeal sent while the reduced rate still applies holds that rate if the appeal fails, while one sent after it has gone up holds the higher figure. Waiting gains nothing.
With no ticket left on the car, Horizon had 14 days, starting the day after you parked, to get the notice to you, and the law treats a posted notice as arriving two working days after the date printed on it. A printed date 13 or more days after you parked is late on any weekday.
Horizon commits to giving its decision in writing within 28 days. Keep a copy of what you sent and the date you sent it, so that if the decision is slow or the amount changes, you can show exactly what you appealed and when.
The statute in full: Schedule 4, Protection of Freedoms Act 2012.
How we handle your Horizon appeal
Both sides. The back carries Horizon's terms and appeal details, and it is the side people forget.
The printed date, the period of parking and each item the Act lists, before a word of the appeal is written.
Through Horizon's own appeal form, as the keeper, inside the reduced-rate window where we can, so the frozen amount is the lower one.
We tell you what Horizon decided. If it says no and you want to go on, we take it to POPLA for you.
If Horizon Rejects Your Appeal: POPLA
Horizon names POPLA as its independent review, within 28 days of its decision. POPLA is the independent Parking on Private Land Appeals service, and the rejection gives you the code to use.
An independent adjudicator, not the operator and not the trade body. POPLA has no financial interest in the outcome.
Nothing to escalate within the standard window, and we do not charge again to take it there. The charge is paused while the appeal is with them, but the reduced rate ends: if it is refused, the full charge is due.
We run the operator-stage appeal first. If it is rejected and you want to go on, tell us and we prepare the POPLA appeal too. POPLA is the last stage we act at.

One exception: if the date printed on your notice is 13 or more days after you parked, tick the late-notice box on the form and the case is covered.
