You have to give it a server: "ntpdate ntp1.exa.net.uk" or whatever.

However thanks for the tcpdump, which does indeed show traffic flowing.
Looking again at your ntp.conf, you've got

restrict default ignore

which will be the problem here.  You have to open the restrictions
for the servers you're trying to use, but that might be complicated
by the fact that you're using the pool, with multiple A records for
each entry if your DNS resolver is rotating entries.

Try "restrict default nomodify nopeer notrap" instead of ignore and
see how that goes.
