Filmed early hours in the morning in work yard (UK). Posted/taken from local Facebook page

Filmed early hours this morning in the work yard. I originally thought it was a helicopter due to its movement, but it originally was an orange yellow light, then red for a bit. I checked flight radar but showed nothing. Then a triangle of lights appeared. There was no sound as it moved over my head and the hovered for a bit. Started filming after a few camera shots of the original orb. It moved behind the building out of sight. The last few seconds of the video shows a triangular looking object.
