We are planning on putting some coving up in our lounge, and possibly
hall, primarily for aesthetic reasons but also as a convenient means
to run some cabling (Ethernet, TV, surround speakers, and some
switched lighting sockets in parts).

It seems that most plain coving styles are available in 100mm and
127mm. We bought a piece in both sizes and offered them up and
immediately opted for the 100mm size but I can't help feeling this may
have been a bit of knee-jerk reaction to the larger 127mm looking
bigger than it really is.

The lounge, in this 2007 'new build', has dimensions 4.6m x 4.2m x
2.5m so not the smallest of rooms but certainly not the biggest
either, and not a Victorian ceiling by any stretch.

Any recommendations? I appreciate it may be down to personal taste but
I don't want to make the 'wrong' decision that I'll later regret so
I'm hoping someone in the know will say something like '127mm is the
standard, and you'd only usually use 100mm in a small flat'...

"Bunched" cables are all supposed to be rated at the voltage of the
highest volt cable there. There might be crossover issues. Mains
cable is best kept separate from audio/video cables. Or screened from
it.

Mains is supposed to be kept 50mm away from other (e.g. comms)
according to the on-site guide (so that a single misplaced nail can't
connect mains to something else in a fairly disastrous way IIRC).

And yes, in practice, running all that stuff in parallel over many
metres _could_ cause a problem with interference. Speaker cable won't
be screened.

On the subject of size, we chose the smaller because we thought it
looked more stylish, less cumbersome. 3.5 * 3.5 * 2.4 room. We also
chose the polystyrene rather than plaster because it's so easier to
put up (lighter, no nails) - but that probably won't apply with all
those cables resting on it, unless you've already dug them in and
fixed them there.

All the things you mention sound like they should be going under the
floor or around the skirting is possible, rather than at ceiling
height, but I assume you know your own house and needs better than I
do!

Cheers,
David.

Thanks everyone for the comments - they've been very useful.

I had considered the cable grouping issue, and was planning on
strategic tacking of the cables to the wall/ceiling so as to maintain
seperation between mains and LV. Subject to further measurements of
the coving rear profile I think I can make the seperation 50mm.

I have considered other options for routing but coving seems the only
viable solution so far without some serious invasive work. The walls
are block with dob-and-dab plasterboard and there's a doorway, french
doors and a fireplace, within the perimeter. Surface mount cabling,
with the coving for cover, seemed to me to be the best way of doing
it?

The coving I intend to use will be either Surecove's polyurethane
offering or Gyproc Lite which, whilst being polystyrene I think, is
paper covered.

I shalln't be leaving the drawing board before I'm certain my plan is
good and proper so any further comments/suggestions would be most
appreciated.

Looking at the coving in B&Q today - 4 or 5 different makes - it seems
that even with the typical 100mm/127mm offerings they still vary
somewhat in overall size/appearance so I'm still undecided which size
(if any) to go for!

I forgot to mention that the floor is solid, however I've not looked
inside the ceiling yet although I'm pretty sure the joists run
perpendicular to the best way to the other side of the room. The
upstairs floor, being a newish build (2007), is probably chipboard
sheets glued down just for extra difficulty.

Hi Mathew

On the subject of coving size, our dining room is only 3.8 x 3.4m x 2.33m
and this will just about take the 127mm cove.
We like coving but have opted for the smaller 100mm profile in the hallway,
this being 1.4m x 3.1m x 2.33m.

As you say this is all very subjective, but consider the other posters'
comments on cable segragation before proceeding to avoid abortive work.

I've got 100mm in all rooms (that have coving) - it looks "fine" (as
opposed to lumpy) but is is OK for 2.4m high rooms of any size. Some may
find a larger coving more appealing, but it's OK IMO.

20+ years ago the builder of my house put in 127mm coving tin the
living and dining rooms, the former 18ft long. The builder who
extended the dining room to 22ft for me recently put in 100mm coving.
I'm not sure that I would have noticed had I not spent three years
selling coving, amongst other things, a few years ago. Even having
both rooms in view it's difficult to tell. I doubt that any visitors
would notice.

No use for running many cables behind, but I have done a couple of
rooms in a 1960's (ie low ceilings) house using the 65mm Duroplymer
coving from Wickes and would definitely recommend it - easy to cut
with a fine blade, light enough to stick up easily and, being smaller
than usual, covers the wall/ceiling gap with intruding on the room (16
x 12 and 10 x 12 in old money).

Just my tuppence worth....

That's reassuring to hear, thanks!

I think I may be leaning more towards the 100mm as having measured
properly the ceiling height is actually 2.4m so we're really not
talking that tall and I can't imagine it looking too small but, if
anything might too large could be a potential.

I may end up dropping the running of lighting cable, and stick to TV,
Ethernet and speaker. The last thing I want to do is a bodge, and
certainly not something that approaches being dangerous and/or non-
compliant.

The problem we have is that it was something of a small luxury to be
able to switch (and dim) the table lamps in our last lounge from the
doorway (and one place more importantly) - a real convenience that we
used every day. I'm sure we could live without it here, but if I can
find a way I'd like the functionality back...
