We've got a small office, with one wall that faces almost exactly south-
east and is damn near entirely glass. With no aircon and a big chunk of
computer kit in the office, you can imagine what it's like at the moment!

What's the options for some kind of film for the windows to cut down on
heat transmission, whilst retaining most of the light transmission? The
building management don't want anything to be "visible" from outside - no
logos, no visible tint, etc etc.

Suggestions, please...

There isn't anything that will be effective and won't be visible in some
form or another. The least obvious would be a neutral tint solar control
film. Even a light tint, which you might persuade them to accept, will
reduce solar gain by a noticeable amount. Google for solar control film or
heat reflecting film. The other way is an external sun shade, like a
traditional extending shop canopy.
