I'm extending the remain cable in my conservatory, can I put in twin and earth under the new floor screed which will be 75mm thickness and will be round the edge of the conservatory and the floor finish will be ceramic tiles. I have seen it done without any protection but wanted to make sure it was ok, I don't mind putting in SWA which but might be unnecessary ?

Run it in rigid or flexy conduit or use lengths of waste pipe. That will protect it against movement and the rigours of the screed laying.
If its a ring, make sure you run two cables!

Thank you, I'm having floor sockets in my conservatory because of full glass type therefore have no choices, I don't know if it's done this way, I'm thinking of using cable tray and nuts/bolts the cooker boxes which is 68mm thickness to the cable tray and plastic pipe in between for the T&E cable so the sockets all line up after floor screeding is done which will be 75mm thickness, any problem or how is it done?
What type of flooring will you be having, and how will it be cleaned?

Oh poo.... 
Masona - do you plan to ever wash the tiled floor?

if he continues the conduit on out of the wall then he's got a drain for it
Yes, I'm fully aware the problem with water but we will take great care with dry to dampness towel and not the usual wet to clean the floor. I feel I don't have much choice as I having full glass conservatory and no where to put wall sockets because of the shape of the upvc profile frame without being an eyesore unless they do slimline wall socket?
What will you be plugging in, when and why?
Have you had a sub floor poured yet? Is there then a finish screed to bring the depth up?
If so, I would fit the deepest boxes you can to the sub floor, packing up if the FFL is much higher than the boxes top. If you can source them (not many local places will stock them), use boxes extensions to extend the galv box, and fit the galv box to the sub floor.
Then run conduit between the boxes, using female conduit adaptors at the boxes. If you need to put in a bend or a set, pull them with a spring - dont buy pre-fab bends. No more than 180 deg worth of bends (two 90's, one 90 and two 45's etc).
Take the conduit back to a convenient place in the house, and from there turn your rings T+E into singles. Use an adaptable box (gewiss etc), or a flushed box if you so wish. The box could be in a cupboard, under the kitchen kick board etc.
Make sure your galv boxes finish approx 4 or 5mm below the FFL - level with the screed would be good if you are tiling. Most floor sockets do not fit flush if you fit the galv box flush with the FFL.
I think you have been chatting with someone about this - You mention "remain" in your original post, when I assume meant "Ring Main". Either way, you don't have a "Ring Main", you have a "Ring Final Circuit".
Not sure why you mention cable tray to be honest. I would secure the conduit with galv saddles less the spacer bar portion (because very few wholesalers stock or know about plain old saddles).
I will also mention RCD, Part P, Pull-through, round conduit, saddles, MK, earth sleeving and 20mm - just incase you fancy a google

Not yet, getting it ready and start digging the footing on Monday
Okay just a bad habit calling it a ring main!
I'm thinking so all the sockets will be in straight line specially with the tiles plus the floor screed hold all the cable tray and sockets down better spreading the load maybe, because I'm not sure the concrete base before the floor screed will still be a bit green for fixings?
I'm just putting in the cable/sockets ready so the floor screed can be done then the electrician can finish the work at the later stage.I will also mention RCD, Part P, Pull-through, round conduit, saddles, MK, earth sleeving and 20mm - just incase you fancy a google
