What is meant by the condition: 'I apply to subscribe to an IFISA for the years 2025/26 and each subsequent year until further notice'?

This condition allows us to keep your ISA open for subsequent years until you wish to close it. This simply means that we don't have to ask permission each year to keep your ISA open. You are not required to make further deposits or investments unless you wish to, and your future ISA allowances are not affected.
