Some, down in this part of the world, do. The OS grid is based on a
square 2500km on each side. That is subdivided into a 5x5 grid of
500km squares, labelled A-Z (omitting I). The whole of mainland
Britain falls inside N, S and T(*). Each of those is further subdivided
into a 5x5 grid of 100km squares, also labelled A-Z. All of Hampshire
(barring a couple of coastal regions) falls in the SU 100km square,
for example.
You can then specify coordinates within those squares using
eastings and northings to the required accuracy: so SU424155 is the
entrance to the Zepler building where we have meetings, to 100m
accuracy.

(*) The Orkneys and Shetlands fall mostly in the H square. Rockall
lies in square MC.
