It depends upon whether the person was adopted before - or after - 1975.
This is from the website you linked to :
What happens next depends whether you were adopted before or after 1975.
If you were adopted before 1975, you will need to attend a meeting with an adoption advisor. If you were adopted after 1975, you may request a meeting or receive the information directly. Where applicable, an adoption advisor from your chosen organisation will contact you to arrange an interview.
You also have the option of approaching an approved intermediary agency about access to birth records to help make contact with a birth relative.
I was adopted before 1975, so had to go through a 'process', including an interview.
If the adoption was after 1975, I'm guessing the records may be more easily accessible - but I actually don't know the answer to that.
