Looks okay.

Missing dot on the end of "xen.letmethink.co.uk". "@" not legal in
the email address part of the SOA; should be
"alex.letmethink.co.uk." Note also the dot on the end of *that*.

Missing dot on the end of "xen.letmethink.co.uk."

In reality you should have at least two nameservers.

That's wrong. The record should either be:

2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.c.f.1.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa. IN PTR xen.letmethink.co.uk.

or:

2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 IN PTR xen.letmethink.co.uk.

Since the zone name is c.f.1.f.1.f.1.0.8.a.b.0.1.0.0.2.ip6.arpa,
leaving the dot off the end of the second example will make it
equivalent to the first.

Also your server doesn't appear to be allowing queries.

When it is working you'll need to put in a support ticket to get it
delegated to you.

Cheers,
Andy
