I am thinking of switching. Is it correct that if I do this today, the switch will not happen for around 3 weeks?

switching usually takes 17 days from the day you start, you can't change that once you start but you can cancel as you have a 14 day cooling-off period; just occasionally if there are problems it can take longer but most go through in 17 days.
If you have a date in mind count back 17 days and switch.
