Hi all.
I apologise in advance for any formatting errors, any advice on how to fix them would be appreciated as I can't figure it out using the preview.
I hope you can help me appeal a Parking Charge Notice To Keeper I've received and that I have followed the forum guide correctly.
On 8th March 2025 at 14:55 the driver parked in the car park for Brighouse Sainsbury's which due to its convenient, centre-of-town location, was also used to frequent some nearby charity shops. This took slightly longer than anticipated and therefore when returning to Sainsbury’s to buy some shopping, the 90 minutes free parking at the car park was elapsed but the driver, having forgotten the arrival time thought they could quickly grab some shopping and leave the car park. The driver then shopped during what should have been a quick shop but due to difficulty finding some items and asking for help from store colleagues to find them then took until 16:48 to pay and then after walking to the car park the driver left at 16:55 having walked to the car park from the front of the store.
I as the registered keeper then received the attached Notice to Keeper on the 22nd March 2025.


The driver has collected the following evidence from around the area today to aid in my appeal.
The driver has a reprint of the receipt from the driver’s shopping which shows the time and date of the shopping being at 16:48 8th March 2025, and the value of the shopping which was £21.78.
The driver completely acknowledges they have overstayed the maximum time allowed, are there any applicable grounds with which to appeal as to my admittedly untrained eye, the NTK looks PoFA compliant?
This is the sign on entry to the car park from a 30mph road off a mini-roundabout

These signs below are repeated around the car park and are all identical. The driver could not find any that were damaged and all are under streetlamps.

Unfortunately, the only pictures of the layout of the car park are these Streetview images, but please trust the driver when they say they are completely representative of the car park as it was when the driver parked.

One issue the driver could find was complication of the issue as a second PPC is also in operation, with the following signage displayed all around the car park.

The driver has approached Sainsbury’s in-store manager in an attempt to get this squashed from their side, though they have told the driver that they cannot as this would incur a charge for them. The driver has not yet demanded the Parking Charge be cancelled by Sainsbury’s corporate customer service or via an email to the CEO or similar, but is not above this.
Help drafting an appeal case and course of action to POPLA should the case get that far would be greatly appreciated also as the driver is not in a position to pay anything, either on principle or financially, particularly given the fact that the driver recalls the car park was not full.
