You are having a laugh at our expense right?
What you are doing IS ariel work and if you only hold a PPL then you are very clearly breaking the law. Just because some guy "up north" is currently getting away with breaking the law does not make it right for you to do so.
In just the same way as a PPL flying an air taxi because the aircraft rental and costs are picked up by someone else and there proper job is to transport people around..........
