Dare I add my 2 pennies worth - I checked the Altitude Angel Drone Safety Map and it looks like you’d be fine so long as you’ve landowner permission to take off and land etc. That said, best practice and so on, it might be an idea to inform the Met Police Film Unit (very nice, helpful etc and unbureaucratic) and check the NOTAMs for the area as you’ll be flying near an oil depot (whom you could also drop a line to). That way, if someone sees your drone and calls the old bill they won’t react!
In case all that sounds a hassle - I found it an enjoyable part of flight planning chatting to these people. Good luck and have an enjoyable flight!
