I can answer my own question!!
I have just received my electricity bill and it does have a section of 3 tarifs - 6am to 5pm, 5pm to 10pm and 10pm to 6am however, written underneath each tarif the price is identical - 0.162684tl per kwh.
So I just called Aydem Elektrik and they said if you want to benefit from the different price tarifs then the owner of the property needs to apply directly to Aydem Elektrik and fill out the forms otherwise you will just pay the standard 0.16.....tl (which in my opinion seems like a pretty good price anyway!!)
KKOB- you know if these forms can be picked up at Tedas because the nearest Aydem office I can find is in Mugla??
