Confirmed. My (non-exit) relay in Amsterdam is blocked. Another
(non-tor) server in Amsterdam is not blocked, nor are my non-tor
servers in the UK, SanFrancisco or NYC blocked.

As for getting this changed, that may be difficult. You could try
contacting the site through the page at:
and selecting the "I have experienced a problem accessing or using the
website or some part of it" radio button and then commenting. You could
contact the NHS at the (postal) address below. You could contact the
DoH (Charles Massey)

As evidence in favour of Tor's value, you could point to the "who uses
Tor" page at https://www.torproject.org/about/torusers.html.en. You
could usefully explain the obvious value of anonymity in browsing health
related sites.   

And, since you appear to be in Cambridge, you could look for some
support (and possible advice) from Ross Anderson

he almost certainly has experience in dealing with awkward parts of
