Hi. As the possibility of DS going to uni is only 2 or 3 years away, you need to look at deposit based savings rather than anyhing that is equity based (which should be for no less than 5 years by the way).
Look at plans that are tax free to star with such as cash ISAs (which DS can also have one of) and National Savings.
If you put money in DS's name, it should be in some form of trust. The reason for this is that when he reaches 18, technically the money becomes his to do what he wants with. So instead of going off to uni, he could blow it all on wine women and song !
Buying property is also too risky in the short term. If you bought somewhere now, there is no guarantee you could sell it again when you need the cash.
Having said that, once you know where DS will be going to study, you could buy a property in that location for DS to live in and rent out spare rooms to others on his course to cover mortgage costs etc and/or give him money for living expenses.
You say you don't want to put money in to a pension, but from what you have said I take it that DH at least is a higher rate tax payer. Depending on his income, he may only have until April 2011 to take advantage of pension tax relief at 40%. 40% tax relief on pension contributions is a massive boost to a pension fund and I would not be quite so quick to dismiss it.
Why has he lost money ? If it is just down to fund performance from 2007 to 2009, then he is not alone and the markets have been recovering. If he has been mis-advised, such as transferring a pension from that of a previous employer, then he should complain to the adviser.
Hope that is of help.
PS. My DD is off to drama school in London in September and looking for sponsors
