Thanks for the reply

I'm aware you don't own airspace, and using one of the online aircraft trackers it's surprising to see how many aircraft are flying overhead surveying the land for one reason or another.
However, using the nuisance neighbour analogy, I can cope with someone looking out of their window but when they start aiming a camera into you garden it becomes an issue. And if they were to build a structure that overlooks the garden then planning would consider privacy.
The problem with reporting illegal drone use to the police is how on earth are they going to be able to find who it was? With many crimes now they seem to be unwilling to do anything about it unless you have all the answers for them for example clear video footage of an incident.
So, until something serious happens to trigger more legislation there doesn't seem much anyone can do. Even the jamming devices seem to be illegal although I'm not sure who would enforce that (would a drone operator say "I was illgally flying my drone when it was illegally jammed...").
