It depends on the site and where the bank account is that you're transferring into. They should tell you before you do it.

Why not use switch/maestro if you are from the UK? It's free.

I recommend Cardrunners for superb poker coaching. It was honestly the single biggest improvement in my game signing up there! Sign-up fee might seem steep, but it pays itself back within weeks.
