Got to agree with Egg, your scenario screams fibre. If cost isn't an issue I can't possibly see why you'd use anything else for it. I'd get shot at work for even suggesting copper for a job like this TBH! Fibre is easy don't be afraid of installing it - and it'll thread through a hose easily too if you wanted.

But by that point it still may have been worth waiting.

Tbh, I'm out of touch with fibre and have no idea of costs anymore.

Waiting isn't really an option, there will be people laying some mains cable very soon, cheers all for your responses I'll have a look at costs for a reliable solution and I'll let you know what we end up with and the result!

I would look at maybe installing a dedicated 2.5 SWA cable just for the powerline ethernet.
One end connected to the nearest socket in the house and the other a socket behind the computer just for the powerline adapter.
If there are sparks on site they wont mind doing  it, and the cable wont cost much more than cat6 and the equipment less than fiber.

I've had issues with cat5 runs over 100m before and wireless is too flakey

if there ant any sparks or they wont do it i will if it is anywere near me.

feeding the cable into the hose is easy

use some string first, with a nail (or something heavy) tied to the end of it, while one person feeds it into the end of the hose, another walks along the hose with it spinning the hose around.... as you spin the house the nail moves away from you pulling the string in... then tape string to cable at the end and pull it through... or... you can fix something light to the end of the string but so it only just fits in the end of the hose... and then blow through with an air compressor :-)

use decent braided hose, not b+q hosepipe etc.. :-)

Was gonna suggest something similar, except 150m  of string would create quite a drag on something like a nail. My solution would be to get a high power rare earth magnet to run along the outside to pull the string through. On the plus side, once the jobs done, you'll have a fun magnetic toy to play with...

What do you mean here? A separate cable to the heavy duty mains cable that's already going in?

The one that's going in is likely to be more heavy duty than that one.. Either way I imagine that the noise over power would be worse than that of a cat6 cable of the same length?

I think if the powerline solution was anywhere near as reliable companies would be bending over backwards to do this, I can't see it being great over this distance at all compared to a cat6/fibre solution.

The main feed going in will be much bigger, 10mm2 at that run I would imagine. Powerline would probably work fine on that cable but if there is a lot of load on the cable you might start loosing stability.

The reason I suggested a separate smaller cable (2.52) is that it can be dedicated just for the powerline adapters so no load/interference to effect the data transmission.
At these lengths the resistance of cat6 cable would get high, it is only 0.5mm2 there is a reason it is only spec'd to 100m

I do work in loads of offices and commercial buildings that have started using powerline, it is just so convenient pretty much anyone can set it up. Its not very secure though, everyone on the street that is one the same phase as you can access your data if you dont have the encryption setup properly.

1. What is the difference between CAT-5, CAT-5e, CAT-6, CAT-7...
The Simple Answer:
CAT-5 is rated to 100M
CAT-5e is rated to 350M CAT-6 and CAT6e is rated to 550M or 1000M depending on your source
CAT-7 is supposedly rated to 700M or presumably 1000M

Today there is no approved CAT-6 or CAT-7. While some folks are selling products they call Level 6 or 7, there aren't even specs for them, making CAT-5e the best available option. CAT-6 cable is being made with 23 guage conductor wire as opposed to the slightly smaller 24 guage for CAT-5e and also has a separator to handle crosstalk better.

Those figures seem plucked out of the air to me. I've never seen anywhere quote figures like that before. Even the official cat 6 ieee spec sheet says 100m

on the same page :-

5. What are the maximum lengths for cables?

For Solid UTP:
Fast Ethernet 100baseT 100 Meters (328 feet)
Twisted Pair Ethernet 10baseT 100 Meters (328 feet)

Recommended maximum lengths for Patch Cables made from stranded cable:
Fast Ethernet 100baseT 10 Meters (33 feet)
Twisted Pair Ethernet 10baseT 10 Meters (33 feet)

I believe you may be able to get away with a coupler to join 2x 100m cables.
cant quite remember exactly what the lengths are, may be less than 100m, but can
get around the 100m limit.

Found that page looking for cables that might do better than 100M  :) also found someone saying you can do 250m HDMI at 1080p with dual CAT5 cables :)

Doing it via wireless would probably be the easiest in terms of install etc but its not very reliable, the firm I work for now had a seperate office a few hundred meters away (For those who know Newcastle the main office is on the quayside just next to the milenium bridge and the satelite office was behind the law courts which we had a direct line of sight roof top to roof top) so they got a company in and installed wireless.  It was usually fine but had some major problems, at one point there was some temporary generators installed for an event on the Gateshead quayside 150m away in the opposite direction and they caused so much interferance it stopped them working.  Needless to say everyone was happy the day they closed that office!

As for how to do this sort of situation I'd probably go for fibre as well, its not that expensive really just slightly more awkward in terms of getting it terminated at either end correctly but am sure there'll be a video or two on youtube showing you how.

Heres your cable for you, should be fairly wel resistant to any thing under a garden...
