You might be suffering from the bind 9.8 CNAME issue. See the recent, repeated discussions in the archives, including a link to a quick one-line patch you can apply to see if it fixes it.
I know this is a moot point now (since Andrew eventually discovered that upgrading his Netgear router's firmware fixed the problem), but it was obvious from the first post of the thread that it was *not* a CNAME issue, since Andrew was having problems resolving an A record for even the name "nhs.uk":

   Jun 17 12:02:38 eccles named[4689]: client 127.0.0.1#36651: query
   failed (SERVFAIL) for nhs.uk/IN/A at query.c:6199

I'm happy for Andrew that his problem is fixed, but it would have been more satisfying to know what 
the root cause was. "Upgrading the firmware fixed it" unfortunately doesn't even 
necessarily imply that there was a bug in the old version of firmware, since sometimes the mere act 
of upgrading a networking device clears out some bogus/corrupted configuration data and thus 
"fixes" the problem.
