300k just sitting there

[blossomhoney2]

I have roughly 300k sitting in a foreign bank account which I have managed to save up over the past years through working abroad, and 90k sitting in NS&I on 4% interest. I don't want to buy a property but I don't really have any idea on what to do or where to start with investing.. anyone able to advise?!

I would speak to an independent financial adviser, OP. I'd want some of that in a pension, some saved for long term and some available immediately. I'd want the maximum £50K in premium bonds, too.

You've done so well to save so much!

As you have money abroad, get tax advice from a tax accountant. Could you simply bring that money from abroad to the UK... I don't know.
