One useful thing here is the ONS concept of a "Built Up Area". That aims
to give the normal human name of a defined place - for example,
Mansfield and Maidenhead are both in the list, and mean what someone
living there would expect them to mean. And it has subdivisions for
major settlements - for example, the BUA of Greater London includes
BUASDs of Bromley and Camden.
Shapefiles are available from the ONS Geography website, and are OGL, so
they're compatible with OSM.
The downside of ONS BUA data is that it's only updated once per census,
so the current dataset is now a bit out of date - it doesn't take
account of new developments on the edge of existing settlements, for
example. But, as a simple source of names, it's very valuable. And
alterations to boundaries can be mapped on the ground, provided you've
got an existing boundary to work with.

As far as local government is concerned, there is a defined meaning of a
town. That is, any settlement which has a town council (eg, Evesham,
Newmarket). And, for larger settlements, the word "town" is what most
people would call what is, officially, a non-metropolitan borough (eg,
More generally, while there's no single definition of a town, it can be
reasonably assumed to be the default terminology for any built-up area
unless you know for certain that it isn't a town (eg, because it's a
city, or it has a parish council, or is too small to have a council at
