No council permit, closure of roads/footpaths or cherry picker required for the inspection of a building in central London using drone technology

We carried out a visual inspection of the facades, gutters, parapets, roof etc on a building in central London that has various access restrictions due to its location in a built up area. Accessing each side of the building with a cherry picker would have been very time consuming and costly with permits required from the council because one sides was on a busy road.
