Loft Ventilation - Can Someone Propose a "Solution"

Best illustrated by a couple of pictures showing the long stretches of ducting crossing one side of the loft to the other. Just wondering if I could perhaps use the insulated ducting and somehow make it more functional as I am pretty sure this ain't working correctly.

Problems with condensation in the hose? Is it an extraction fan connected to a tile vent? Why the remote side of the roof, not near the fan?What sort of roof is it? Boards are unusual for a tiled roof.

To work 'properly', ducting, especially the 'concertina' flexible type you have, needs to be as short as possible. Inflexible, smooth, ducting is much better, if you can use that instead.
Insulating the ducting for an extraction fan will not make it work better, but will reduce the likelyhood of condensation forming in the duct and pooling at the lowest point. (A friend of mine had a similar set-up to yours, and was not amused when it gave way and dumped a load of water onto his ceiling!)1 -
Bad ducting ...vent via a short run. Soffit or eves/ At least yours vents out. We have 4 bathrooms and they just boxed the Xpeliar in the attic with plasterboard ..no external venting.0

Someone did say that may be able to vent through soffit through a vent connector or something like that but may have to cut a section to get them to fit. Is it ok to vent through soffit?Outstanding mortgage Dec 2016 £214,500

As others have said - If you have to go to that vent location
smooth solid ducting (white plastic pipe)
support it so it doesnt sag.
dont let the colder side of the pipe fall down towards the fan
insulate it so the air stays warm till it exits and hence less likely to condense
Replace the fan (assuming it some feeble ceiling outed thing) with a larger inline fan like an Manrose MFT100
Then it should work a bit better than what you have.1 -

For more power you need an inline fan in the loft.
And yes, it can go though sofit. Or you can move the tile vent to other side of the roof.0 -
Are these vents designed to be on opposite sides of the roof to keep intake and exhaust apart?0
-
No. The primary goals is to keep the vent pipe as short as possible and insulated.0

Fan in the ceiling wont push much air at all that distance on a corrugated pipe0
