Option to transfer ISA out

I feel like the option to transfer out without having to sell all your assets should be provided, even if it means charging a fee as other brokerages offer this and it’s incredibly convenient for those who want to change broker.

Agreed it makes me nervous about transferring in any large amounts currently with no option to transfer out again in the future as holdings. A lot of money can be lost moving as cash if out of the market for weeks in these volatile times.
