Rang twice in the middle of the afternoon. Did not leave any message. Very odd.

Claims to be from NHS but rang me at 11pm? So strange.

I don't answer unknown numbers on my mobile so I didn't answer. They didn't leave a message. Thank you for all the comments here and for reassuring me that it is NHS/UCLH.
