I have just added this to the map of places to fly your drone at Drone Scene:
Chobham Common is intersected by the M3, I visited the part north of the M3, most of the part to the south is under the Fairoaks Airport FRZ but can seek permission easily to fly there. Very large space with few overhead hazards so very easy to keep VLOS.
Quite a few car parks around the common, I visited the Chobham Common Roundabout car park. Can also park on Burma Road (the opposite side of the common) and take off on the road (maintained by the local council) or common and also get views of Longcross Studios next door.
I checked the bylaws noted on the rear of the notice board in the car park, it does not restrict flights of drones, just states that they cannot be used to cause harassment and damage or something along those lines. Only thing to note is that the common is a SSSI so common sense is required, don't fly near/close to trees during nesting season etc, I mostly stayed up at 80-120m to also reduce noise.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 08/04/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location. Landowner permission may be required before taking off.
