I have a few 3 core SWAs supplying sheds and garage coming into a plastic junction box inside the house (in a mini plant cupboard) where they connect to individual T&Es using chocolate block. The T&Es then go onward into separate circuits in the CU on the other side of the house.
The SWAs are terminated using CW type glands. There are no banjos inside or outside this junction box, so I think the armours are floating. Supply type is TT.
The T&Es are poked through holes in the top of the junction box, no gland.
This work was done by an electrician 4 years ago.
I want to replace the junction box with a bigger one and move it to an adjacent wall myself. There is enough slack in the cables to move them. Then I want to get an electrician to connect and test a couple of extra SWA and T&E cables.
I don't want to make any fundamental errors in replacing the box, so questions as follows.
Cheers!

- Is the box move itself notifiable?
- Is a plastic box still ok? Or must it now be metal?
- The box is inside the house, are CW glands necessary, or would BW glands have been ok?
- Must each SWA armour be connected via a banjo to the earth core of it's respective SWA in the junction box?
- Must the T&E be glanded into the box? If so, I have some of these, are they suitable? https://www.toolstation.com/ip68-gland-locknut-kit/p80473
- Anything I've missed?
Cheers!
