As it stands, that will probably only get you a CPL(H). (Even if you go to HAI, once you factor in the cost of living for 18 months etc.)
As you've probably already picked up on other threads, a CPL(H) on it's own is next to useless.
You're probably looking at about £60-70k if you budget for hour building and an FI rating. A little bit more if you want to go down the higher risk (offshore) IR route. If you want to stay onshore and fly SPIFR somewhere down the line, the bill is much nearer to £100k.
Once you factor in
ALL of the costs, training in the US doesn't actually seem to save that much. And what you save in pounds sterling, you lose out in contacts and reputation back in the UK.
Best of luck either way.
