Hi MAAZ,
I will defer to Gryphon for you local area, he knows more of the local rules than I ever will. Down in the antipodes we do things a little differently.
From the reference that Gryphon refers to it looks like EASA is placing the requirement back on the company to confirm obstacle clearance in all circumstances.
In my airline we have a performance engineering department that will do exactly that. Having said that we are not a small operator and I'm not aware of us having ever done a charter to an airfield for which we were not able to obtain the relevant obstacle and terrain data.
