Thanks;
but when I got similar charge in February last year before I retired,
I raised it up with the estates department of the hospital and they were very unhelpful.
They were supporting UKPC, that I needed to have a permit. But then, I walked to work so I didn't see why I needed one.
I only drove to work at night or weekends.
I appealed to UKPC and they rejected my appeal,
so I just ignored the parking charge and any subsequent correspondence from them.
I didn't hear from them again until this new charge.
Oh, I have now received the NTK letter.
