Parking Eye issued a "fine"

[THE_Liam]

If you're worried about not paying, write back and ask them to prove you were driving, as the fine is levied against the driver, not the registered keeper. They'll write back asking you to declare who was driving, and you just write back to tell them you have no legal obligation to do so, and ask them to prove you were driving themselves. Boom, no more contact.

that's a nice point actually; shall include.

You won't shake off Parking Eye with that. They will just pursue the registered keeper quoting Protection of Freedoms Act 2012.
