Moving 1 year ISA to S&S ISA- how? Hiya! I’m a bit confused with this. So, I’ve got 40k in a 1 YEAR ISA with Barclays Bank (used my full allowance for the past 2 years) that matures in June 2025. I want to get rid of that and move those 40K plus another 20K (use my full 2025 allowance) to a Vanguard STOCKS&SHARES ISA I basically have no idea of how to do this, when can I do this…
