Durian, Bayswater and Queensway are both in Westminster so you could direct your question at them. I've sent you a link to their virtual Civil Enforcement Officer (I still haven't posted 5 posts so can't add it here). If you were Notting Hill side of Chepstow Place / Ossington Street then you would have been in Kensington and Chelsea.

Success would surely depend upon whether the sign in the photo was the only one being displayed and how visible that sign was when entering the car park. If it was the only one then I agree that it would look like a clear case of inadequate signage.

Lamma, Sorry I don't understand, are you saying that the appeal has succeeded because of inadequate signage?

Hi Durian, In answer to your question you sent to me at motorcycleparking.com I think the key issue here is whether the pavement (footway) forms part of the car park. If it does then any parking, regardless of whether it is in a marked bay or not, would require you to pay and display. If the pavement is not deemed part of the car park then Retail Parking Solutions Ltd should not be able to clamp any vehicle parked on it (that would fall under the durastiction of a Civil Enforcement Officer or a Traffic Warden and would depend upon whether you were in London or not ). On the matter of you not seeing the sign and not knowing whether the pavement was part of the car park, alas this is no excuse in law. My advice is to pursue Retail Parking Solutions Ltd as you are doing but in the meantime try to ascertain from a local CEO whether the pavement in question is enforceable by them, if it is then it's cut and dry that you have been wrongfully clamped. I hope this is of help. Good luck with the appeal. Will P.S. Sorry about the links, I can't add them properly as I haven't posted five posts yet.
