I need to bring cables from upstairs to downstairs to the consumer
unit. Total around 10 T&E in various thicknesses.

The only relatively fool proof part of a wall is where the existing
cables come down and I don't want to remove these until the wiring
is complete.

I therefore need to run them down a separate part of the wall - I
have a 2 foot space between the kitchen door and the living room
door that would be ideal.. Sods law says that somebody will no
doubt bang a nail in the wall in the future, co I need to give the
cables protection.

As I see it, I have the following options:

a) Feed the cables through metal conduits, then plaster over
these. The plaster will have to be a bit deeper than the existing
half inch. The cable from the shower would have to be placed out of
conduit at the edge of the wall.

b) Bury the cables in the plaster as normal, then cover with a
sheet of suitable metal for protection

and that's it! any other suggestions?

Would there be any problems with running a T&E cable (1.00mm and
2.5mm) in a 10 foot vertical drop without any support?

Thanks

Thanks for the comments.

It is not a cavity wall, which makes it more difficult. The existing
cables are buried in plaster.

It would seem like the only real option I have is to run the cables
down the existing location. I will need to look into this further and
do some more checking.

In my original post (as above) I mentioned running cables in a 10
foot drop without any vertical support. What I forgot to make clear
was, in this instance, the cables would be in individual conduits and
not just left dangling. Would this make any difference?

Why not stick ( no nails , hot melt, impact adhesive whatever) DON'T
NAIL OR SCREW IT!!!!! pvc trunking onto the wall over the existing
run. then you can remove the lid and add the cables as you add new
circuits .Then when all cables run , remove the temp plastic trunking
chop out the plaster and remove old cables the put new cables in wall
with plastic or galv steel top hat type protection , doubt you will
get any wide enough to cover all the cables in one go or run in the
conduits remember you can get oval type conduit , round would probably
involve chipping away some of the brick/block to get it flush under
the plaster then plaster/ make good

That might have to be one way of doing it. As I'm doing it a bit at a
time, I would much rather have dove it permanently at a new location,
disconnecting the old cable at the CU then connecting the new one as I go
along. I could then clear out the old stuff at my leisure.
