Result! And this may help other people get their charges overturned. One of the things I did after receiving the PCN was to contact the retail park for whom Parking Eye were operating the car park. I explained to them in the letter that there were mitigating circumstances (2 young kids and one elderly dad in tow with my wife) for overunning the "allowed" 3 hours max. Last week someone from the retail park phoned my wife to say there was nothing they could do, but today totally out of the blue I got a call from someone else from the retail park to tell me the charge would be cancelled if I can give them the ref and car reg no. Apparently even though they fobbed my wife off each case gets passed onto another section of the retail park and is dealt with on its merits. Nice to know someone has the public's best interests in mind. In the meantime I have sent Parking Eye the letter in my previous post and only this morning took photos of their crap and totally inadequate signage. Maybe a waste of time after all but I was preparing to stick it out for the long haul. Hope this is not seen as cheating but may save someone else the hassle of waiting for the whole thing to expire if you try a similar route to this. Good luck everyone.

My wife parked in a Parking Eye run CP for over the 3 permitted hours. I received the PCN as registered owner and keeper of the car, unfortunately I let them know my wife was driving the car when I phoned them to try and get the charge overturned (no chance, of course). We have since spoken to Citizens Advice and the retail park owners who both advised NOT ignoring the PCN. CA suggested writing to them to ask for evidence and saying as I was not the driver I am not liable. Sent the following: I acknowledge receipt of your Parking Charge Notice. It seems that you have got my details from the DVLA and I confirm I am the registered owner and keeper of the vehicle in question. You need to take this matter up with the driver concerned. In the meantime I absolutely deny that the amount claimed, or any amount at all, is due to you from me. Unless you provide evidence to substantiate your claim against me I shall be unable to assist you further in this matter and I restate my denial of this claim. In a couple of days the PCN ticks over from £50 to £80. We are both concerned and I feel I may have stitched ourselves up by telling them over the phone that my wife was driving and later sending this letter saying effectively it wasn't me! I'm sure this is similar to other postings but can someone give us some helpful advice before my wife decides to pay up and forget about it?
