Try FS Cables
Bingo!
Many thanks Tim, exactly what I'm looking for.
Let us know how much ;-)
I certainly will do.
Nah. Suck, or blow: a bit of cotton wool or similar on the end of a bit of sewing cotton; tie fishing line to cotton if a longer run; apply end of vac to microbore/pipe/ducting. Works surprisingly well, though I've never tried it in anything as tiny as microbore; but for 20mm conduit and larger corrugated ducting, it worked first time for me (in these cases using thin polyprop string as the draw wire).

Why armoured? There is some poit to armouring mains, where digging through it might be dangerous, but with cat 5, its conventional to put it in plastic pipe instead...
Having read what the situation is, I'd say fiber too.
Its not that expensive, and not too hard to terminate to the sort of standard needed for relaible 50m transmission.
Ty Black Box or betterbox for various interface units.
Use mains water pipe as ducting. Thats pretty much what e.g. BT do when running twisted pair around the place. Leave a string in and you can pull fibre throughh later..
Easy, get a 2l PET drink bottle and feed the thread in (tie a washer on the end first). On the other end tie a few knots so its a bit smaller than the pipe bore and feed that end into the pipe. With the pipe as straight as possible tape the bottle neck onto the pipe. Make a hole in the bottle to take a compressed air feed (spare tyre will do as an air source) and pressurise the whole lot. The nylon cord will easily go down the tube. The most I've managed was nearly
100m (using spooled cord) although that had to be done twice - the second time after securing the washer on the end :-).£800 for 50m.
By the way - FS - incredibly helpful people, definitely bookmarked.

Twisted-pair ethernet is isolated to 2kV.
Taken care of in the cable.
This is the only bit I have a problem with. If STP (shielded twisted pair) cable is used, this forms a direct earth connection between the house and office which could carry a current flow. This current could be significant depending on whether the OP has exported his house earth or used a TT installation for his office.
I'd perhaps only earth one end of STP, or stick with UTP.
Flexible conduit? Kopflex sort of thing? It's expensive, but pretty tough - spiral wound overlapping steel with a pvc covering.

Don't forget the shielding used in STP cable.

Good reason to stick with UTP then ;-)
Couldn't get blow to work in a 40m run I had through 20mm flexible (all pvc) stuff, I ended up using magnets on that - hence my suggestion, also the kit is portable and cheap.
Except that is blue for water. There is a standard colour code for buried services, I think it's probably best to stick with it.
Unless it's a pretty straight run and large diameter pipe I doubt you could pull another cable in. Use the the old CAT5 to pull the new fibre in, assuming that there are no inaccesable bends...
I put a single CAT5 down just 10m of flexable plasitic conduit this summer and unless the conduit was pretty straight there was no way the cable was going to go through.
