Well, it's amazing how difficult it is to find the actual spec on these things! I suppose that's always the case with cheaper stuff (and not just with bike components) - so irritating.
For anyone who might need to know in the future - I've just received an email back from Espresso. They say to use the shortest ISO square taper BB possible (103mm is best). Although "anything up to 110mm should be fine".
Also, these cranks are 110mm BCD. A new 130mm BCD replacement will be coming out in the future.
