Fly below 120m (400ft)
Flying below the legal height limit of 120m (400ft) will reduce the risk of coming across other aircraft, which normally fly higher than this.
Always look and listen out for other aircraft that may be flying below 120m (400ft), such as air ambulances and police helicopters.
Your drone or model aircraft must never be more than 120m (400ft) from the closest point of the earth’s surface.
If you fly where the ground falls or rises, such as over hills, mountains or cliffs, you may need to adjust your flight path so that your drone or model aircraft is never more than 120m (400ft) from the closest point of the earth’s surface.
Flying over very tall structures
If the person or organisation responsible for a very tall structure over 105m asks you to carry out a task related to their structure, you’re allowed to fly higher than 120m (400ft). For example, if they ask you to take pictures for a survey.
You must never fly more than 15m above the structure.
Your drone or model aircraft must be within 50m of the structure horizontally when flying over 120m (400ft).
