if I'm installing cat6 down PVC conduit like these is there any point buying LSOH cable or shall I just stick with the cheaper PVC stuff?

where i need a couple of shielded runs will this FTP be ok or should I look for S/FTP? (it's running i) down a 3m length of landing parallel to a number of electrical mains cables, ii) across a bedroom floor above a garage door motor and flourescent light)

Presume I should be using solid core and not patch for the permanent wiring?

LSOH is related to fumes given off when on fire. The boggo PVC cables will perform the same shifting bits and bytes as LSOH/LZOH

There are specific regulations around running patch cables near mains. There are minimum distances they must be in order to run parallel. I can't remember what it is however. This is for safety.
Shielding is more related to noise rather than safety - i.e. performance is better in high noise environments.

For structured cabling, you should only use solid core. Stranded core is only for patch cables which should generally be as sort as practical. Performance of stranded core is worse than solid core for shifting bits and bytes over distance. Performance of solid core on patch leads is worse because the contact to the pins isn't as reliable and simply knocking the plugs can cause problems. Don;t bother making your own patch leads. Always just buy them. Save yourself some patch lead headaches.

for running parallel to elec mains cables (short lengths) will U/FTP be enough or should i get S/FTP or F/FTP? The cost of U/FTP is 25% the other two.

For safety, the shielding in S/FTP and F/FTP is irrelevant. It's still dangerous, shielded or not. For noise, I'm not sure that mains electricity actually interferes much with the signal. Provided there is enough distance. Dado trunking keeps network cable around 100mm away from mains cable so I'd guess that 100mm is far enough away. I've seen installations with that using unshielded cable over pretty long runs without issue. My guess is that A/C runs at 50 Hz whilst the signal in a Gigabit ethernet cable runs in the Many MHz range. (I believe it's close to 100 MHz)

why dangerous? It's going in its own plastic PVC conduit, just there is a bundle of ring mains cables running along that area too. Probably 3m or so overlap. I might get 100mm separation, but can't guarantee it.

TBH it's probably not dangerous. If it's in its own separate conduit personally I wouldn't be concerned.
There's some information here: http://www.cablemonkey.co.uk/cmdocs/...alDistance.pdf if you want to consider specs. I quick skim of that suggests that you have nothing to worry about.
