The appeal letter is the case. Horizon Parking decides appeals in writing, and what the letter says, and avoids saying, sets up everything that follows, including POPLA.

This guide covers the structure that works, the wording mistakes that lose appeals, and what the £9.99 prepared letter includes.

What a strong Horizon Parking appeal letter contains

  • The reference block: PCN number, vehicle registration, site and date, exactly as printed on the notice
  • The keeper position stated once, cleanly: appealing as the registered keeper, without identifying the driver
  • Numbered grounds: POFA 2012 timing, signage compliance, the Horizon Parking ANPR record, landowner authority, Code of Practice breaches, whichever the notice actually carries
  • An evidence index: each attachment named and tied to the ground it proves
  • The outcome requested: cancellation of the charge

The wording mistakes that lose appeals

Most rejected appeals are rejected because of what the motorist wrote, not because the charge was solid:

  • Identifying the driver: once the driver is named, POFA keeper protections are gone
  • Leading with mitigation: "I only stopped for five minutes" concedes the breach and argues for sympathy operators are not required to show
  • Arguing fairness instead of compliance: the winning question is whether Horizon Parking followed the rules, not whether the charge feels fair
  • Contradicting your own evidence: the letter and the attachments must tell one story
  • Sending fragments across several emails: one letter, one evidence pack, one record

Why the keeper wording matters

Under POFA 2012, the registered keeper is not required to name the driver. Liability only transfers to the keeper if the Horizon Parking Notice to Keeper met the Schedule 4 conditions and deadlines. A letter written correctly from the keeper position keeps that test in play; a letter that says "I parked" gives it away in three words.

Why template letters get rejected

Operators process appeals at volume and recognise generic templates instantly. A template argues grounds your notice may not support and misses the ones it does, and the rejection it earns becomes the record POPLA reads at the next stage.

The letter that works is built from your notice's own defects: the dates on it, the wording on it, the signs at that site, the evidence you hold.

What the £9.99 letter includes

  • Your Horizon Parking Charge Notice assessed against the compliance grounds
  • The appeal letter written around your notice and evidence, structured as above
  • Exact submission instructions for the Horizon Parking portal or post
  • The POPLA appeal prepared under the same £9.99 if Horizon Parking rejects
