Ha, that is a remarkably vague location

If they want to hold the registered keeper liable, using the provisions of Schedule 4 of the Protection of Freedoms Act, they must 'specify' the relevant land on which the vehicle was parked. As Dave notes, 'The University' doesn't achieve that.
Personally, I would be minded to submit a simple appeal along the lines of the below. I would probably leave out the specifics of the location and save that for a POPLA appeal if Ipserv reject. My reasoning here (which others are free to disagree with) is that this reduces the chances of them providing the full location in their rejection letter and subsequently trying to tell the POPLA assessors that they
have specified the relevant land (this still wouldn't do, but they might be able to convince a particularly dozy assessor).
Dear Sirs,
I have received your Parking Charge Notice (Ref: ________) for vehicle registration mark ____ ___, in which you allege that the driver has incurred a parking charge. You have failed to issue a Notice to Keeper that is fully in accordance with Schedule 4 of the Protection of Freedoms Act, and it is now too late for you to do so.
There is no obligation for me to name the driver and I will not be doing so. I am therefore unable to help you further with this matter, and look forward to your confirmation that the charge has been cancelled. If you choose to decline this appeal, you must issue a POPLA code.
Yours,
If appealing online, be careful there are no drop down/tick boxes that cause you to identify who was driving, and keep a close eye on your spam folder for their response. If they do not respond within 28 days, chase them.
