A mate of mine had to go to Hale Top house to sort his ticket out. When there he asked that they give proof that his parking permit was not on display, as suggested by the ticket. They got in touch with the clampers and they said that when a ticket is issued a photo of the car is taken as evidence.
"Fine" he said "let's see it."
A photo of my mates number plate appeared. All that proved was that the car was there, not that it was there illegally.
The fine was quashed and my mate departed a happy bunny!!
By the way it's £60 pound for a ticket and another £40 if you get clamped.
Most of the a/c hangars are equiped with portable bolt croppers etc. which, i'm sure, they will hire out for a nominal fee!!
