For a look at just how out of control costs are at Nominet, it's instructive to look at the personnel costs of the NZ registry since, apart from the order-of-magnitude difference in the number of domains under management (and hence the size of the various databases associated with them) they both should be carrying out the same sorts of activities (managing the namespace, dispute resolution etc.)
In the 2013/2014 fiscal year, Nominet spent...
£8,102,000 on wages and salaries
£982,000 on social security costs
£319,000 on other pension costs
£1,136,000 on director remuneration
TOTAL: £10,539,000

The NZ namespace is handled by 2 organisations, DNCL and NZRS
DNCL spent...
NZ$709,693 on wages and salaries
NZ$137,830 on director remuneration
http://dnc.org.nz/content/DNCL_Annual_Report_2014.pdf
NZRS spent...
NZ$960,916 on wages and salaries
NZ$126,750 on director remuneration
https://nzrs.net.nz/sites/default/files/NZDNRL_Annual_Report_2013-14_2.pdf
For a total of
NZ$1,670,609 on wages and salaries (£777,185.91 using XE.com currency conversion)
NZ$264,580 on director remuneration (£123,056.19 ditto)
TOTAL: NZ$1,935,189 (£900,242.10)
So Nominet spent £10,539,000 and the 2 *.nz organisations spent £900,242.10 on the people that should be responsible for doing
almost exactly the same thing.
(I'm afraid I simply can't accept that it costs an extra £9.5 million in personnel costs to stick 10,000,000 more entries in a few databases)
