attached the window to the outer leaf of a cavity block construction

it depends where you want the window. Ours are either midway in a 600mm solid stone wall, or in a new timber frame. Either way, the fixing is a strap behind the frame, or alternatively a screw through the frame, which would be  a shame.

Where the cavities are closed, and the window is in the cavity then what do you attach the straps to? The inner leaf reveal?

 

As said, depends where the windows are exactly . If they are fully within the cavity closer then run the strap fully from inside reveal to outside reveal. The window manufacturer should be able to advise as they may have a preference.
