No problem with majordomo; it's operating as it's supposed to operate.

It looks as if nhs.uk refuses delivery of a single message with lots of 
recipients.  If so, they do it as an anti-spam measure and have made 
the decision that the tradeoff (mailing lists don't get through) is 
worth it to them and their users.

There's a program you can install to "help" majordomo handle delivery of 
lots of mesages to single domains; the program is called something like 
"bulk_mailer".  You should make sure you haven't got it installed; if 
you do, it's exacerbating the problem.

That failing, you can try contacting the postmaster at nhs.uk to see if 
they can whitelist your list.

There are some other mailing list programs (I believe mailman fits this 
category) that can be told to send individual messages.  Perhaps you 
can find another mailing list program you can use.

(Qmail, used in place of sendmail, doesn't "bunch up" multiple 
recipients at a domain, but it's a sendmail replacement and won't work 
on a RaQ.)
