Be wary is the best advice.
Be wary of "professional" financial advisors who are required by law to declare an interest in any product they recommend, that law is there for a reason, its not your profit they are necessarily interested in.
Be wary of anyone who promises any get-rich quick investments, there is no such thing.
Be wary of banks who promise you the world with their investment products and while not breaking the law may not be totally demonstrative about the level of fees they charge either as a "management" fee or as a penalty if you change your mind.
My only advice would be the same advice that I gave my eldest, DO save something even if you don't know where to put it yet, she has a simple deposit account that pays a small amount of interest with no costs attached (or none that are taken after they've calculated the declared interest rate) and she's now in the habit of saving a decent sum of money every month towards a property deposit in the next few years - its a start.
