I had one of these, and they eventually gave up. The advice on this site is accurate. I found it most helpful to realise these "fines" are simply invoices. Use the "template letters" and remember the threats are empty

I think it would be useful to people to see the process and the tactics these these companies try - So, they 1 Stick an invoice that looks like a parking ticket to your vehicle 2 get the registered keepers details from DVLC 3 Write 5 times asking for money, adding further charges and making vague threats about court action, vehicle seizure and bailiffs, while igoring all correspondence 4 Write a 6th time claiming there was a contractual agreement with you, and assuming that you parked in the area, because you are the registered keeper I have used all the templates, and twice asked UKCPS to cease and desist. I even phoned them on 4 October. Their latest letter claims I have made no attempt to contact them! So now I will send copies of all my letters (based on these excellent templates) by registered post, and ignore further correspondence. Any clues what they will do next - contact a debt recovery company I expect. Has anybody had any success asking the police to investigate this as a harrassment issue? D

I got one of these "Parking Notice Charge" tickets while parked for 5 minutes on double yellow lines, at 21:55 on a Sunday Night! The ticket calls the road a "Serv Rd" - presumably service road - while I thought it was the public highway. Is my situation the same as those in car parks etc?
