Simply Build It

Most lights have live as well as switched wires at the ceiling rose if ceiling fan was originally a light you could have selected live (normally red) instead of switch (normally black with red sleeve). On the other hand I fitted years ago fan/lights in conservatories where I was instructed to fit a switched spur in bedroom with basically a permanent live to fan/light which was controlled in the conservatory with a radio controlled remote. This would cause a problem radio controlled remote switches cost about £12 from screwfix. With blue and red wires I would expect also a yellow which would point to a two way system. The double red and earth is the correct way to wire switches not often used. This will mean instead of a black with red sleeve at the light you will have a red careful noting of how it is connected before removal or locating which is double red at the lamp is only way. Only one wire of a double red would normally be connected to live at light the other will go to lamp. But quite frankly I can't follow what you have to give any more than basic wiring methods I would think only safe way is to call in an electrician. Sorry I can't help more.
