Is Ditra an overkill on concrete with ceramic tiles?

Pull a bit of carpet back and look for fixings if there are none then it's a floating floor which is just chipboard over insulation (kingspan)....not screwed or nailed down to joist..

I looked again & noticed that you said the joists were 200mm apart, strange make up even if it's a suspended floor, normally 400mm apart even if they are trying to strengthen the floor knowing its to get tiled.

It's a new conservatory so its just chipboard down. There were plenty screws in the chipboard. Thought I was going to have to get nanolight adhesive to stick to all that metal haha

I would go back to the architect & ask him again what exactly the floor make up is before I went any further.
It sounds like a suspended floor but those joists are very close together.
Better news for you as at those centres it should be rock solid.
