Just another bit of (anecdotal) experience, my OpenReach engineer seemed very happy to put the CSP in a totally boarded out loft, indoors, fishing the fibre through sofits etc using the old 5-line drop wire which he disconnected.

I think as long as its easy and safe (as it sounds like it will be), they can be very accommodating.

that's amazing thanks. I was hoping for that as drilling and patching in an external wall must be much more time consuming than running a cable into some ducting!

That said, if the ridges are not too big with small dips between them, they shouldn't interfere with the pulling. It's when you have those large and rubbery ones which might become difficult.

sorry but i found myself reading that in a frankie howerd accent..........

Add the

"Lubricants may help a bit, but its far preferable to have it secure from movement."

and you have considerable "double entendre" material.
