S&S ISA - newbie investing

[IndigoBluey]

I have around 30k sitting in a cash ISA and I’m thinking it makes sense to have some of this pot better off sitting in a S&S ISA. I’ve never opened a S&S ISA and I’m very new to investing. I had a browse on Martin Lewis site earlier although they do say investing is not their specialism but there was a table summarising various ISAs. Does anyone have any advice for a newbie looking to open a S&S ISA? How do I go about choosing which one and I take it I should look for a managed one as opposed to choosing my own S&S? I also have a small amount in Vanguard FTSE Global All Cap Index Fund. Not sure whether to leave that where it is or transfer it into the S&S ISA that I will open. In case relevant, aged 38, higher rate TP

Is there a reason you don't want to continue with a low fee index tracker?

I suppose I am worried about going over the annual amount in interest and then having to pay tax on that. I was thinking it might be better to have some of the money in a S&S ISA with some kept in the cash ISA

If you want something really simple and without high fees then I recommend something like the Monzo or Trading 212 S&S ISAs. Deposit money, select risk level (high, med, low) and forget about it. Trading 212 is also flexible (i.e. you can take money out and put it back in again) and you can move money between cash and S&S ISA.

It would definitely make sense to use an ISA wrapper for your investments so you don't have to pay tax on income and gains. Whether you should stay with cash or do stocks and shares depends on what you think you might use the cash for?
If you are a higher rate tax payer have you also thought about pension contributions as this would be even more tax efficient.

Thanks all. I have opened a S&S ISA with Trading 121. Looks like there are options to create a pie, which I might opt with just as a starter!
