Correct way of trunking cable

[Fordy81]

So I'm needing some new sockets put in in a room and will be getting an electrician in to do this as it requires extending a ring main and beyond my knowledge.

However to save costs I want to do the channelling myself. Can anyone tell me what I need to know to satisfy the electrician? Round conduit? Oval? Depth? It's basically concrete/breeze block with dot and dab plasterboard on top.

Thanks in advance

Probably nothing (just plaster wires in) - but the only way you can ascertain what will 'satisfy' your particular electrician is to ask him/her.

If you are going to cut the chases in the walls, it's particularly important that you ask the electrician precisely where they should be before you start doing anything.

Kind Regards, John

You would need to know how many sockets he will install, where you want them to be, which route he will take the cables, which means he would have to mark out the safe zones for you to chase out, whether the existing ring main is RCD protected...………

Basically, as John says, the only thing you can do is speak to your electrician. He may not want you to do anything other than clear furniture from certain areas and maybe lift carpets if fitted.

Thanks for the replies. Basically one is to go up the wall directly above another socket for a tv. Another will be going to the side, got floorboards up so probably the preferred route. But will get someone in to look at it. Thanks

You may find, (or the electrician will), that the socket going above may be on the route of the cable feeding the lower socket because the cables come down from above rather than up from below. The electrician will determine this before he starts channelling.
