Where's the best place to work as an HR professional in London?

I'm finishing off my CIPD Level 5 Diploma and due to have a baby this year. I currently work in a busy team at a small university as an HRA. It's a really long journey for me, so I'm thinking about my next steps after I return from materinty leave for the three compulsory months. I have a wish list for the type of place I'd like to work next and wondered if anyone had any suggestions please?

  • Big team with the opportunity to progress and learn
  • Ideally in an environment that follows best-practice and strong working practices
  • Supportive, caring employer who really cares about all staff in the organisation
  • Passionate HR team with excellent leadership
  • Fun environment with people who love what they do
  • Central London, Bloomsbury, North London, West End

I know it's quite a long wish list, but I want to make sure I end up in a role I truly love, that I can really help people and where I can develop and grow. I'll have a strong foundation of two years in HR by then and my CIPD level 5, so hopefully I can go for advisor or officer.

Any ideas greatly welcome. TIA.
