Hi Katy,
From what I remember you go and meet your PC and she’ll ask you all about why you want surgery, what you expect from it, what kind of look you are going for and how big you want to go. From that she will be able to match you with a surgeon who she thinks best suits what you want. You can have as many consultations as you like with as many surgeons as you like.
She will also go over all the boring medical questionairre and ask how much research you have done and when are you looking at having it done. And also obviously how you plan on paying for it. She will also show you an implant and maybe some pics (cant remember that bit.) After all that you will be able to book a consultation with your surgeon and go from there. Hope that helps a bit x
