I'm about to embark on a house renovation and plan to chase out walls for new sockets, I will be using the usual 2.5 T&T so how deep can it be and would using the plastic oval piping be of benefit ?[/quote]
The best way to chase walls

You should ask your electrician those questions - well, the one about the depth, anyway, as he's the one who will have to certify that it complies with the Building Regulations. Remember it's not just Part P compliance he's signing for, it's all the relevant ones, which in this case includes Part A.
It would be rather unfair to expect him to take responsibility for structural decisions made by somebody else.
Re the conduit (not pipe) - it can be useful if you need to add or remove cables at a later date.

There are building regulations that concern depths of chases within walls:
Horizontal chases no more than 1/6th of depth of the wall (leaf /skin).
Vertical chases no more than 1/3rd of the depth of the wall (leaf/skin)
The cables must also be routed in permitted safe zones.

Installing your cables in conduit, would only be helpful when it comes to the next rewire and most likely by then the design of the installation will be different. Plus you must factor in the cables ratings for installing within conduit as the current carrying capacity will be effected.
I tend to chase out the depth back the bare brick/blockwork, normally by doing this enough depth can be offered for base coat and finish plaster and if your luck dot'n'dab will cover the cables.
But as well as the cable chases, there is always the socket sinking to look forward to

Aye, price your job accordingly.
Lathe & Plaster are a nightmare. As is hard brick.
Personally I get my apprentice to do stuff like that
I have some stuff that your apprentice can be doing.

Run after them?
Not what you were asking, but if you are chasing the walls yourself and they are brick or block I would heartily recommend using an Armeg SDS scutch chisel - I bought one recently and found it was far easier and faster than any other method I've tried, and produced far less dust than a proper chasing machine.
First task - go and get a defibrillator, just in case...I have some stuff that your apprentice can be doing.
Yes it is a bit messy isn't it, a good vacuum and sealed doors should help, you only need to do it once thou
