Are plumbers being sacked in their thousands?
It is an ever demanding market.
Here in the south, there is a huge shortage of plumbers, my mate works for himself and earns more than I do and that is not insubstantial.
I'm thinking the same as you but if the lad says so...
(I would never have done this, dads company or not)
Neither would I. According to the Gas Safe register each individual gas safe engineer has to be registered by the company, so if he left they would still have a record of his personal registration and getting that transferred to him as self employed shouldn't be an issue.
Seems pretty straight forward actually.
