Low deprivation isn't the same thing as wealth. Sheffield Hallam is very middle class with only a couple of enclaves of poorer areas, and bits of it are genuinely quite wealthy, but its average income won't be as high as a lot of Tory seats in the South East. It's also a relatively professional, public sector, educated middle class, none of which helps the Tories these days, though it might help the Lib Dems.
It seems generally that in measures of deprivation, the lowest areas are those which are consistently 'average' if you like, or middle-class, rather than wealthy; very wealthy areas being often quite close to poor areas.

And if you exclude Queen's Park/Harrow Road which are lighter on 'managers,' Westminster North was almost certainly Tory in 2015. Not sure about 2017.
