PhD bug I have family in Croydon. They are all off work and sledging instead. I think probably people in Lunar House won't be able to get there either, which is prob why they aren't answering the phone. It is pretty exceptional circumstances, so I wouldn't stress too much about you appt, but that is obviously very easy for me to say. But that's my local knowledge. Croydon is higher than central London too, so will be snowier.
