Beware of the charges!
Especially elder, disabled and families need to be extra careful.
I looked but couldn't find any signs that this car park belongs to a private owner, but it does. No indication of how long you can stay without a charge. However, you might unexpectedly receive a parking fee notice (do not confuse with a council parking fine!). The demand is outrageous £100. They do not say how long you were supposed to have for free! As an option, you can pay £60 within a very short period of time. Interestingly, it takes around a week to deliver that letter, so you might have a couple of days to decide to pay or not.
Please consider carefully if you pay or dispute! Because you might have to pay. Money Saving Expert has some valuable advise on their forums.
Pure robbery!
