Retail Park ANPR Parking Fine UK: Two Visits, One Charge

Updated April 2026 · 6 min read

ANPR cameras at retail parks are a blunt instrument. They record a number plate entering and a number plate leaving — but they cannot distinguish between a single extended stay and two entirely separate visits. When a driver makes two separate trips to the same car park on the same day, the camera system can combine the gap-free entry and exit records into a single "stay" that exceeds the free period. This scenario is more common than operators like to admit, and it is a strong ground for challenge.

The situation

Tom visited a busy retail park on a Saturday morning. He parked, collected a click-and-collect order from one store, and left — having been on site for around 45 minutes. His car park was recorded as entering at 10:12 and exiting at 10:58.

Later the same afternoon, he returned to the same retail park to shop at a different store. He entered at 14:30 and left at 16:05 — a further 95 minutes. Two legitimate, separate visits. Both well within the 2-hour free period individually.

Smart Parking's ANPR system recorded only the first entry at 10:12 and the final exit at 16:05 — a combined "stay" of nearly 6 hours. A Parking Charge Notice for £100 arrived two weeks later, citing a 4-hour overstay.

Checking the grounds

Tom ran a check on the charge. Smart Parking is an IPC member, which means the independent appeals route — if the operator rejects his first appeal — is the IAS (Independent Appeals Service), not POPLA. That distinction matters: he needed to use the correct service.

The grounds were clear. Tom had made two separate visits to the car park, each well within the permitted free period. The ANPR system had no mechanism to distinguish between a single stay and two visits with a gap between them. His exit at 10:58 and re-entry at 14:30 represent a 92-minute gap during which his vehicle was not on site — there was no continuous stay.

The POFA check showed the Notice to Keeper was served on day 14 — just within the 14-day window — so that procedural ground was not available. But the two-visits argument was strong on its own.

Writing the appeal

Tom's appeal to Smart Parking was direct. He set out the factual sequence of events: two separate visits, the gap between them, and the fact that each visit was individually within the free period. He requested that Smart Parking provide the ANPR images for both the morning entry/exit and the afternoon entry/exit, pointing out that these would confirm the vehicle was absent from the site during the intervening period.

He also provided two pieces of supporting evidence: a bank statement entry showing the click-and-collect payment time-stamped at 10:43, and a receipt from the afternoon store visit with a timestamp of 15:22. Together, these anchored each visit to a specific time and confirmed legitimate retail use on both occasions.

What happened

Smart Parking rejected the first appeal without engaging with the two-visits argument, issuing a generic rejection. Tom escalated to the IAS — the correct independent service for IPC member operators — and submitted the same evidence with a clear statement that the operator had not addressed his specific grounds.

The IAS upheld his appeal. The assessor noted that the ANPR evidence provided by Smart Parking confirmed two separate entry and exit events and that the combined recording did not represent a single continuous stay. The charge was cancelled and cannot be pursued further.
