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 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.
