She definitely looks familiar. Most girls appear on multiple agencies, often with different names, and sometimes with very different photo sets that sometimes it is hard to tell it is the same girl. The London escort guide website used to be a good resource for this, but appears to be down at present.
It is quite awhile since I have used an EE agency, but I always found Top secret, Hot Collection and Diva to be good. Diva in particular was good at keeping its website uptodate with who is actually working. Top secret and Hot collection often got girls first, before they advertised elsewhere. Admiral had by far the largest selection of girls, but this was mainly because they had no quality control - I understand they have since changed hands so this may have changed. After some bad experiences, I wouldn't touch Babylon with a bargepole - it is usually a sign that a girl is getting desperate when she has to advertise with them.
