It really isn't that difficult. There are three bolts underneath and one in each wheel arch at the top corner of the bumper. There are also two screws nearby that screw in upwards. To get to these you need to peel back the wheel arch liner. Putting the suspension on high makes access easier but don't go underneath without blocking it up.
The front inner grille needs to come off and if I remember correctly the headlamps too, or maybe I just took them off for the sake of it.

But that is also just three bolts each.
The headlamp washer hose has a snap together connector which you just pull apart and the fog lamp electrical connector is attached to the inner bumper on the opposite side.
Once everything is unbolted and disconnected a sharp tug will see it pop off.
