Mr. Enda Walsh:

The use of drones is very broad. It could involve someone looking at the gutters in a house who needs to go over the house or estate agents photographing a house's neighbours. There is no specific height restriction. There will be restrictions on the different types of drones in operation as it goes up, so the larger drones would have to keep to greater distances from people and buildings but, as Mr. Gavin said, in a general sense, there is no specific height restriction. Nevertheless, the restrictions on the operation increase as the risk of the operation goes up.
