Regulation of UAVs in the United Kingdom prescribes the rules that operators of unmanned aerial vehicles must follow in the UK.
In August 2012, The UK's Civil Aviation Authority (CAA) stated that it would require non-military drones larger than 20 kg to be able to automatically sense other aircraft and steer to avoid them.

The Civil Aviation Authority created a "Drone code" which lists the following regulations, forming the acronym DRONE: "Don’t fly near airports or airfields, Remember to stay below 400 feet (120 m), Observe your drone at all times – stay 150 feet (46 m) away from people and 500 feet (150 m) away from crowds and structures, Never fly near aircraft and Enjoy responsibly".
Further: On 20 February 2019, the Department for Transport announced legislation to extend the ‘no-fly’ zone around airports, banning drones from flying within 5 kilometers (3.1 mi) of runways.
