To not know how to get interest on savings

[PeteKnew]

I've saved up £25,000.
It's been sitting in my current account past 6 years.
Can I get any interest on it?
If so, what sort of account should I put it in? And how much interest can I expect to get? Do you have to wait 12 months before you get any interest?
I know nothing. Never had savings before.
Currently with Barclays.
Thank you to anyone who can advise.

Not a cash ISA

A stocks and shares ISA

Average return over last 15 years is 6.79% for a UK stocks and shares ISA

Average UK stocks and shares ISA has risen by over 8% over the last six years so the OP has actually missed out by even more that I said.

Yes, there will be some bad years but if you are holding savings for a reasonable length of time (eg a few years) stocks and shares have always outperformed cash.

1. You didn't say s&s, people aren't psychic.
2. You can't say WOULD have worked out and they ALWAYS outperform cash - it MIGHT have worked out if she picked the right s&s. She could have lost money.

Given you literally acknowledge OP isn't coming from a position of strong knowledge and confidence about money, I don't think it's responsible to assure her that she absolutely would have had an extra £8k when the whole USP of S&S is that they are both (generally) higher return, but for higher risk.

Implied by the fact I suggested that the vast majority should be put into a stocks and shares ISA though?

Ok, cannot say a simple FTSE tracker stocks and shares ISA definitely would have outperformed cash over an long investment period but 95pc chance that it would have.
