I believe EDINA hold force boundary shapefiles (though a couple of them are a bit off, from what I can remember), plus I believe the licence terms are quite prohibitive/restrictive...
I agree re the neighbourhood shape files being of poor quality. If I was looking to get the best quality boundaries, I'd look to take local authority boundaries and union them up, using the Local Authority / Police Force Area list that has been published (can't find it right now - pretty sure it was a PQ to Nick Herbert when he was policing minister). I expect this may be what the folks at Rock Kitchen Harris will have done for the NPIA/Police API.

The first of these sources is the KML files that the police publish for police neighbourhoods in England and Wales - they don't publish shapefiles for force areas, but you can union the neighbourhoods to create polygons for each force area. Unfortunately there are many problems with the neighbourhood KML files, such as self-intersections, boundaries not matching up, eccentric representations of islands and holes, etc. (I assume that the police API is using this data, since part of Bristol around BS13 7EN which isn't covered by a neighbourhood in the KML files also doesn't seem to have any data from the API.) The other source is the legislation defining police areas for England and Wales. I've tried to identify the areas from Boundary-Line which match the descriptions in the legislation. I think this has worked pretty well, but there is at least one curiosity, in that I'm not sure from the legislation of the status of the Inner Temple and Middle Temple, and I can't find those areas in Boundary-Line anyway. If you want to look at these data, they have the codes POF and PFL respectively in this mapit, and the police neighbourhoods that I used to make up the POF areas have the code PON: http://mapit.jenny.212.110.187.249.xip.io/ I hope that's of some interest or use.
