Maximum flight altitude: The vertical flight limit is 120 meters in the United Kingdom.
Maximum horizontal distance and FPV: Drones have to be always in the direct line of sight in the UK. The maximum allowed horizontal range is 500 meters.
Compulsory insurance: To my knowledge, only commercial drones must have personal liability insurance. However, I recommend that everyone make drone insurance valid in the UK!
Maximum take-off weight (MTOW): from 7 kg certain conditions apply
Distance to airports: You have to keep a sufficient distance to British airports. As far as I know, a particular distance is only scheduled on the island of Jersey. There you have to keep a distance of at least 2 kilometers.
Other safe distances: A distance of 50 meters between your copter and individual persons and buildings must be observed. A distance of 150 meters has to be ensured to gatherings of people and built-up areas (settlements).
Flight bans: Areas with a flying ban can be identified with the Drone Assist app.
Time of operations: Drone flights at night require separate permission.
Regulations for commercial pilots: A permission must be applied for commercial activities. There is a form for foreign pilots (SRG 1320).
Good to know: Frequency determinations: 2.4 GHz without power limitation with digital radio; 5.8 GHz in the range of 5.725 to 5.875 MHz
