3 core/E is generally only used for 2/3 way light switching and maybe timer fans ( in a domestic situation ). as for the conduit you mention, it's more usual to use T/E, sometimes with capping, rather than conduit, which requires much deeper chasing and more time.
 
methinks it's time to get a second quote for the job. apart from concerns about the materials specified, it's common sense anyway. ask any watchdog viewer.

From my notes
Its a conduit system buried into the walls using a channel or something like that.

I thought the 3 core and earth is used for multiple switches ? Not sure.

Also, the 3 core cables isn't that the one used for double sockets etc ? I feel this is the one that someone previously stated is not enough.
No mate a solid continuous conduit system is what it is solid no breaks. no sheathing, conduit as in round plastic or metallic conduit. The 3 core cable would be used for 2 way and intermediate switching, BUT 1.5mm2 OR 1.00mm2 NOT 2.5mm2 cable.
2.5mm2, 2 core and earth or whatever size larger than that has been calculated would be used for RFCs feeding 13Amp socket outlets, your post before this only confirms your lack of knowledge, get some, decent contractors in to quote for the work, please.
 
Pay me for my travel time, time on site, food, accommodation and time already spent telling you what's what and I 'll come visit and give you a decent parts list if that's the way you want to go, extra I could give you a quote for doing the work.
 
So you are saying 1.5mm 2 core and earth to feed the sockets.
Ahh, this and the 2.5mm cables are the wrong ones then. I will discuss this with him, is there anything else that you feel is worrying ?
