Hi GD,
Here are my suggestions -
1) I'm with Squaregain and find then very reliable and competant - my current holding of AEY is in my SS ISA with them, only dealable over the phone but still very efficient.
2) I would speak to Squaregain - when I initially transferred over to them they sorted out all of the transfer of my holdings from my previous broker & paid the transfer/termination charges. Perhaps speak to them and maybe they have an facility in place for the transfer to be made more expediently.
Hope that helps, can only comment on my experience.
Cheers,
Jai
