Still gathering requirements...
Is it likely that the private pension age will be increased so by the time someone in their 20s/30s could be looking at 60 onward?
Reading various articles the Gov seems intent on raising it.
"If you're aged age 36 to 44**, you get your money at age 58. For Generation Y(ish), those from 23 to 35, the magic number is 59. For anyone younger, it will be at least 60." - the Telegraph.
That being said, would it be wise not to throw all the eggs into the pension basket if you intend to retire as early as possible. e.g a big chunk left in the business account.
