Errrr...you can put money into a short term insurance policy.I have done this on two occasions.They are both specific 15 year policies.One has already matured(for eldestborn's university career and was very useful)the other is due just about the time the youngest is at university.
Of course at the time I took them out they were really for use as a means of giving my offspring a springboard into life(house deposit,buy a car) but due to this fecking government's ineptitude the first was used for everyday living expenses for eldest whilst at uni.BAH!
I'll never forgive them for the way they screwed up so many young lives.Barstewards!
Anyway IF you are not considering any form of further education maybe it might be better to concentrate on a pension.However be very careful and get some really good professional advice about this.Ask more than one source.
