Seem pretty available, I used Google, it is a search engine,

On there other hand, floating a tethered balloon 1/3 mile into the air may
be a problem for airplanes.


Definitely in the United States, anyway. For a temporary setup (i.e a
weekend), you would at least have to notify the FAA. They may or may
not give permission, depending on your location in relation to airport
and heliports.

Longer setups would probably require a lot of bureaucracy.

I would guess the U.K. has similar requirements.
