Metal conduits in consumer unit

[Harnoor]

At a property there are old colour wires coming through steel conduit which is connected with flange coupler to old metal consumer unit and steel conduit is used as earth ( CPC) . i am replacing cu with 18th edition box which requires more space so iam trying to put the consumer unit to other side. can i extend the cables by adding metal clad back boxes to each conduit ?

You can, but you may find the knockouts do not line up, maybe plain sided galv boxes, you can drill yourself may be better

Install a length of steel trunking having first drilled holes to match the conduit positions. I prefer to use a chassis punch.

Connect singles inside the trunking and run into your new CU

Wago or crimp

Would that not limit how you can join the cables.

Din rail connecters in a suitable box in my view is more superior

It needs to be metal really so you can make the cpc connection to conduits.

and drill holes at custom spacing.

There are 3 conduits from bottom and 1 from top so it might be difficult to find box to fit in that space

Leave the existing CU in place, gut everything except the earth bar and DIN rail if there is any. Fit DIN rail terminals (And a bit of rail if needed). Refit cover and include a full set of blanks or replace with a metal plate.

Or even mount the new CU on the front of the old.

Can you post a picture or two?

Yes a brilliant pic thanks, I thought I'd made my

reply to your post, not mine.

One of the easiest ways to finish that is to fit a metal plate to the rear of the existing cover to fill the big holes. Of course if you have the skills and tools to make a new front cover...
