I live close to you and had my antenatal care at the lister hospital, thats the QE2 sister hospital, as far as I am aware they do a 12 week dating scan, I made a doctors appointment, they wrote to the hospital to inform them, and just before my 12 week scan I saw my midwife to get my 'green' notes. It might work differently, yyou could call the QE2 and ask to speak to the antenatal clinic, they would be able to tell you exactly what to expect.
