This wouldn't work in the case of civil parishes as components of districts and UA's though. You cannot define a district as the union of the parishes. There are unparished areas, detached parts and "lands common" which complicate the model. However I believe every point in the UK is within some district/UA, and every district is within a county, giving 100% coverage at that level.

Every point is within a district, but not every district is within a
county - unless, that is, you consider a unitary authority to be
effectively two different entities that happen to have identical

I think you understood what I meant. AIUI a UA is normally technically a
district. A city is an orthogonal concept- a "city council" can be a UA
(eg Nottingham), a District (eg Canterbury) or a Civil Parish (eg
Salisbury) that has been awarded that status. And not every city has its
own council of any type (eg Bath). 

And of course a council is not an area, it is an administrative body.
There are admin areas defined in law that do not have a corresponding
council, eg the county of Berkshire and many Civil Parishes. Sometimes
they play games with the naming: Rutland County Council is not a county
council, because there is no extant county of Rutland. It is a
non-metropolitan district with unitary status, whose council is formally
called Rutland County Council District Council. 

I stand by my comment that the "sum of parts" system could work down to
the district/UA level, and not down to the civil parish level.
