raising level of concrete floor

[Spicy]

want to lay porcelain tiles on the kitchen floor. half the kitchen was carpet on top of a floating floor and half was vinyl tiles on concrete. The floating floor had too much movement and no joists underneath to secure it to so we've taken that up. We're now left with a concrete floor nearly two inches lower than the rest of the concrete floor.

Can i just get a man round to pour concrete into the space and level it to the height of the existing floor? Do i need to do anything to the floor before laying concrete on top? it already has a DPC.

Can the concrete go right to the edge of the external walls? there was a gap with the floating floor.
Do i need to put anything on the concrete before laying tiles?

Any advice very gratefully received!

screed it.

get a builder round to quote you on a sharp sand/cement screed.

it may need a membrane beneath the screed.

brilliant, thanks. will do that, was worried it was going to be very complicated. will i need to put anything on the screed to prepare it before laying the tiles?
