A few words to the situation in switzerland for non-commercial.
Most swiss-helo-pilots, PPL and CPL, has a general-permit for landings in non-certified spots.
The restrictions for non-certified spots are very simple:
No landings in urban areas (near as 300m).
No landings above 1’100m, except you have a mountainlicence. (MOA)
Minimum distance (300m) to jail’s etc.
No landings on waterareas.
No landings in private areas, except permit from property-owner.
For night you have to file a ATC-Flightplan.
For night below 2’000GND in class G radiocontact is recommend only.
Most pilots contact FIC for open and close the flightplan. That’s all.
For night in class E and D you must contact ATC for radarcontact. No route etc is required.
FREE flying! Most clearance sound as: „Report when misson complete“.
For night in class C you must contact ATC for radarcontact AND routeclearance, like as IFR.
For private night T/O and LDG at non-certified spots the pilot only is responsible.
Groundlighting, obstacle-clearence etc. is absolut your responsibility.
Have a funny nightflight in switzerland ..... I like it with my B47.
