Easy one.
Fund your portfolio with £100 and maintain that investment for 12 months.
Note: I intend to maintain my investment with this portfolio for years as I have heavy involvement with investments. You are guaranteed the £25 bonus.
I can't advise on the funds as i'm not a FA, however, use S&S if you have not already opened one (or plan to open one) in this financial year.
It's time to get your Invitation.codes account too 😎
