Pcn for overhang on own driveway

Yes, I have, and no, this isn’t a prank. I was shattered when I arrived at 3am, and I definitely won’t be parking like that again. Do I need to contact Redbridge, or will they send the fine by post?

"The front bumper was slightly overhanging the pavement,"

This is a wind-up, surely !

I'd contact the council. Do not discuss the whys and wherefores, just say you found the notice which advised to contact the council, give them the details and ask what happens next.
