In reply to Greenbanks:
They have an obligation to adequately sign restrictions, either thought road markings, signs or both. Adequate is defined in the regs. From your description, it doesn't sound as if they have met the regs.
It is probably worth appealing on the basis that you could not reasonably be aware of parking restrictions, based on their inadequate signage. Include pictures / distances etc. The actual regulations can be a bugger to find, but include them as well if you can find them.
