BUT I suggest that you will need to add on the cost of some dual time once you arrive back in the UK with your new PPL. Air law, circuit procedures and especially the weather are all different here!
Some = an hour or two, which at £150 per hour *may* be £300. When you're talking of $6000 as opposed to £6000 then £300 may not make much of a dent.
The weather is NOT that different here. It may be cooler here, but believe me you can get !!!!!e weather here, there, in the middle of the desert, in LA, in Miami, in France, in Norway, in Greenland....where ever.
In fact you can get nice weather here too, believe it or not.
If anything, the only difference weather will make is that you will end up paying more in a crappy climate due to cancellations, currency or whatever.
There, glad I got that off my chest.
