I parked in a nhs car park. Someone told me it was free and I didn't check. I was parked around 30 min, when I returned I saw a sign and realised it was a pay for car park so immediately bought a ticket. I've now received a fine from a company called IPC. £100 fine reduced to £60 if paid in 14 days. Options are suck it up and pay. Or go through appeal process which is up to 28 days but I assume I'd have to pay the full amount if I lose my appeal. Is having a valid ticket for some of my visit a reason to appeal? I paid for an hour but was was only there 40 min (30 min was prior to buying the ticket)
