Currently commercial drone services provided by companies require prior permission regardless of size where the service
falls within the definition of «commercial
operation» in the Air Navigation Order 2016 which is: ``... any
operation of an aircraft other than for public transport --(a) which is available to the public; or (b) which, when not made available to the public, is
performed under a contract between an operator and a customer, where the latter has no control over the operator, in return for remuneration or other valuable consideration.»
