Best place to invest £500 for 10 years

[Gazelda]

Hi there.
My DD (9) has inherited £500. I'd like to lock it away separately from her other savings, so that it is a pot of money she can always consider as being from her grandparent. I'd like to invest it somewhere low risk until she reaches 18. We won't be adding to the deposit.
Can anyone suggest the best place to invest for her?
Savings accounts seem to offer 3% at best. I hoped there'd be something better than that, but maybe that would involve more risk than I'm comfortable with?
Thank you.

I'd probably put it in premium bonds. Low risk and you have a v small chance of winning something..

I would open a low cost junior share ISA and invest in a low cost wide coverage global equity index fund / etf. Yes it is riskier but 10 years is a long time.

I'm currently earning 40% pa with Scottish Mortgage Investment Trust.

It's pretty amazing, I like looking at it every morning and frequently see that my little stash has gone up by £500 since the day before

It isn't low risk, but for £500 I'd personally be happy to take a gamble.

40% p.a.???!?!?

Yep. Google Scottish Mortgage Trust share price.

Wow, thanks all!
She's already got a few premium bonds, so I'd rather look at an interest-earning investment. But I agree that there's a little extra thrill at the thought a PB might randomly produce a little windfall.
I'll take a look at that bond suggested, thanks.

40%😮. Wowzer. As it's not my own money, I don't want to take anything other than a low risk. But thanks for the suggestion - I might look into it for a little nest-egg of my own!

Sorry Svarte, I meant say that I'll I investigate that ISA you mentioned. As long as it's not too complicated, I might well give it a go. I have nowhere near enough expertise or experience to commit to anything too complex.

If you want to read up on this, then maybe the monevator or Jim Collins websites. Warren Buffet has just won a bet against women hedge fund guy on the return on a 10 year deal of a low cost S&P 500 index fund or a hedge fund, index funds won.

I'd like to invest small amounts of money over the years in these kinds of vehicles like the Scottish Mortgage trust one. How can I do this? Will I need a broker or similar person to do so?
