There tendss to be two phases to an install, the externals who will run a cable from the roadside tap point to the house and perform the bare minimum to achive this, Leaving cable exposed in hedges, mimimal bury under lawn turf where aeration will cut it etc.
Then the second where the installer will route from ominibox to internal points. You will be this guys best friend if you have have draw wires, conduits etc. in place that will enable them to work neatly to route to your desired points. Nodody wants drilling through external walls with spalled brickwork plaster and decoration damage etc. So make it easy for them if such access already exists.
