Thanks for the answer. I am also interested to transfer some stocks from another broker. I just checked the IG transfer process as you suggested, which requires to sign the form and post it to you. Is it possbile to sign the form electronically and post it to you via email?
Just answer my own question - I just followed the transfer process. I received an confirmation email at the end. I was asked to reply the email with the signed form attached. All done electronically.
So far it looks straightforward and stress-free.
@gezmond for my case, it saves the cost of the stamp duty
