I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
I parked in Waitrose carpark, free for 2 hours, walked across Dane bridge just to make sure I was on public land, for TOAL. There's a swing bridge either end of the quay, and a nice church 400m away.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/09/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
