So a flight for a pilot owner/renter who owns a company (trust), flying from UK mainland to Jersey or Man to collect some cash is a business trip, just as a trip between company locations:
Definition of private pleasure-flying defined
The definition of 'private pleasure-flying' is as in the Energy Products Directive:
'Private pleasure-flying' shall mean the use of an aircraft by its owner or the natural or legal person who enjoys its use either though hire or through any other means, for other than commercial purposes and in particular other than for the carriage of passengers or goods or for the supply of services for consideration or for the purposes of public authorities.'
For these purposes 'private pleasure flying' means flying other than in the following circumstances:
commercial operation or use of aircraft by companies for the carriage of passengers or goods as an aid to the conduct of their business and the availability of the aircraft for whole aircraft charter, flown by a pilot (or pilots) employed to fly the aircraft
the non-commercial operation or use of aircraft by a company, for the carriage of passengers or goods as an aid to the conduct of company business, flown by a pilot (or pilots) employed to fly the aircraft
the non-commercial operation or use of aircraft by an individual for the carriage of passengers or goods as an aid to the conduct of his/her business or his/her employer's business
It keeps coming down to the same: the cost of the use of diesel engines for private flying just went up by A MASSIVE LOT
So GA is being dealt a huge blow.
As far as I am aware this decision is european wide, not only UK
