I thought that it mean transferring ISA to ISA but it isn’t 100% clear
Yes that’s not that clear - we are working on a process to enable you to transfer your investments from your Freetrade Account / GIA to your ISA at the moment. We haven’t finalised how that’ll work at this point though.
Will Freetrade allow the transfer of ISAs from other providers?
Not when ISAs are released.
If holding ETF’s will there be any platform fee?
