Demon Internet do allow this. In fact they make special provision for
it; they provide (at no additional cost) a "shadow" DNS service. You
(the customer) set up a single master DNS server for your zone, and
Demon will grab the zone several times a day, and serve it from their
authoritative servers.

I note that Griffin Internet is a UK ISP (and so is competing with
Demon), and also that it offers wholesale connectivity deals - i.e. it
sells services to downstream ISPs.

Demon lets me serve my own rDNS. It is a privilege, and I value it; it's
really difficult, I think, to get the hang of DNS without running your
own live server. Demon has rather hackerish origins, which is probably
behind their willingness to provide this kind of service.
