The Ts&Cs states that
The New Customer must maintain at least the Net Contribution as it stood at the Promotional Period End until 30/04/2025.
If I transfer in £5000 worth of shares, and months later the value goes up to £6000 and I sell £5000 worth of shares and withdraw the cash leaving £1000 worth of shares in the account, then the value goes down to £900. What’s the net contribution at this point?
