George is right to ask about living conditions/salaries etc and to check that he can afford it etc.
The only thing I will add is that if you can not afford this, you can not afford to be an airline pilot! It is that simple.
Yes people do commute from all over, but I'd strongly suggest that as a new line pilot you do not want a long commute as you'll be exhausted as operating into LHR is a very tough gig for your first job these days.
