If its where your intending to work there is no point fannying around doing it else where.
There are ways and means of reducing the cost by doing an IACO PPL first then starting the theory with one of the ground school distance learning schools while hour building abroad.
Then coming to an UK school for CPL and any country for your IR rating.
But you have to outway the savings by how sellable you will be afterwards in the market you want to work in.
Nobody seems to care about the PPL or the ground school. Interesting different hour building is sellable ie don't go flogging around FL. Do some big trips to unusual places eg fly from UK to some !!!!e hole in the north of Norway for a burger and come back through Finland. And FFS mention it on your CV.
CPL/IR they seem to like you to be at the same school. Some do, Some don't care, it comes from a comment from one of the fleet managers at flybe and others have agreed with it.
