How much are we talking about? Before the crisis there were very few places that gave significant funding without securing a property to it in a secure loan with little/no payment holidays, so without a job in a reasonable time you can start getting into precarious positions. Partial funding was possible maybe up to £20-25k via an unsecured loan.
But now we are in the worst economic crisis in living memory with thousands and thousands of pilots being made redundant, investment in any pilot training will be seen as insanely high risk and you may find little help from banks. A lot of heli guys are ex forces anyway, so that may be your best bet.
Just wait it out.
Good luck.
