I finally got my head round it (I think). The pop up gives you an option of accepting cookies or not. If you click Yes the popup disappears, and everything works as normal. If you say No, then Google Analytics cookies are inhibited.
Google analytics cookies aren't stored until you click Yes, and I think the other cookies come under the 'necessary' category, so I assume I'm now compliant.
