What to do with £20k?

[WalkingWavy]

As above basically. I have £20k in a savings account (4%). I don’t need this money, it’s not my rainy day fund as I have accessible money elsewhere for house repairs, holidays etc. I forget this money exists. It just sits there doing nothing. I don’t foresee using this money any time soon so just wondered if anyone with any financial savviness could advise what to do with it. Leave it where it is? I have heard of stocks and shares ISA’s but I’m not very knowledgeable about finances and don’t have family/husband who are either

Absolutely put it in a stocks and shares isa. You would expect to earn 8% on it.

Then come back here and ask questions about whatever you don't understand

Stocks and shares ISA for sure, if you don’t need it anytime soon. Just let it sit there and grow with compound interest

Stocks and Shares ISA for sure. I use the InvestEngine one and invest in the invesco FTSE All-world (FWRG) which is extremely low fee and no platform cost. Already up 16.5% since April, though you can't guarantee returns like that.

This video is a great place to start:

Thank you for the replies, that’s helpful and generally what I was thinking. Of those who use a stocks and shares ISA, which company have you gone with?

Happy to see the first replies are SS ISA and not... Premium Bonds!
On platforms I use Vanguard but I think they changed there fees for accounts under X value. If there fees are ok with your investments I would recommend using them for sure.

I agree S&S ISA. I use vanguard too and invest in FTSE all world, there are cheaper options and you can access the vanguard fund from other platforms too.
I’ve seen rebel finance school recommended on here previously to upskill yourself.

I use fidelity. It does have fees, they're lower if you have a monthly direct debit going into it (£25 a month minimum)
I invest in a few funds: global equities, US equity, UK equity, Asian smaller companies, global special situations.

I second the Rebel Finance School recommendation. It recently finished and the sessions are on YouTube.
