If my memory serves well, a while ago I read a post that you could add fund using debit card into CFD account free of charge (e.g., no fee of 0.7% to be paid).
If this one still holds true then has anyone tried to add fund in CFD account and then move it to ISA/Invest account and there is no fee of 0.7%??
I am aware you could link your bank account but so far, I have no luck in linking my bank account. Also, some people prefer to use debit card.
AFAIK that is not possible anymore. I think they already mentioned it when they announced the fee.

Hey 
,
While the option to transfer funds between different accounts remains available, we’ve implemented a mechanism that detects an attempt to abuse transfers between CFD accounts towards ISA/Invest accounts as a workaround for the fee of 0.7%.
On a side note, Bank Transfers & Instant bank transfers are free of charge and I’ll DM you so we can assist you with that.
