Does anyone know anywhere in the regulations that it states I have to use capping to protect cables when embedded in plaster as I am currently on a rewire, it says in on site guide that if there's no rcd protection it does require metal earthed capping

As for the cost ! It adds pence to a run when using oval conduit .
If installed correctly , it is perfectly accessible when it comes to replacing , even pulling the odd extra cable down when needed .
It looks 100% more professional to the client than just clipping direct , no matter how neat your clipping is , and a damn site quicker .
The above does depend on if the chase has been cut with a decent wall chaser ( but then again if you have not got this or the extract gear to go with it , I pity any other trades working along side you on a rewire ! ) .
I know it is purely down to choice , but it is a no brainer as I see it .

We use sto25 , and all you do place it in the chase when you have fed the cables in ( straight and not twisted) tight up to one side , mark your fixing points normally between two or three for the length drill , plug and fix leaving the screw heads just above the conduit . You will find that it is quite easy and a perfectly sturdy fixing until the spreader comes along , and if the mortar is soft enough , you are able to fix straight in to it , as it is only going to be a temporary fixing for a few days until spread .

More tubing good points...
Let a 'Monkey' (for want of a better word!) fit all your tubing, plasterer makes good.
You come along later, pull cables in, test and finish off etc., knowing full well there's no damage whatsoever to your wiring.
And it improves the Maintainability of the install.

Capping is history, the future is Oval tube, and the future is (has been) here and now!

That would only work (for first floor sockets) if the oval tube went behind the skirting and under the floor and was easy to get at. Would be difficult if there was a joist up against the wall. Its often easier to pull the cables in and then thread the tube over the cables.

Sorry , I did not explain it as well as I could've .
When I said " feed the cables in ( straight and not twisted ) " , this is what I meant .

That should be big enough ?
As and when we need to substantially widen the chase , we use a Hilti grinder with an extract head on it .

Was just guessing maybe bit narrower, won't take standard capping I know that. I was getting a load of slightly narrower capping for a while which was perfect but can't get no more. smallest stuff 16mm? no use.

As good as you would expect it to be , being Hilti !
Keep meaning to buy another grinder , as they sent two extract heads out with the grinder when we brought a hover and grinder combo kit .
Tried to give the spare head back , but the rep would have none of it !?

I have been on their site , but can not tell which one it is at the moment .
I know it is on one of their 5" grinders , but as I tend not to get on the tools nowadays , and especially not for chasseing work , I am not quite sure which one it is !?
I do know from when I was more hands on , it was the daddy ! Especially when it came to cutting a perfect box hole .
I am going down to work early this week so should be back on Wednesday night this week , I will have a look for it at the yard and if I remember when I get back home post the model number up for you .
