Could it be that BT's Digital Voice has already "claimed" the existing number?

Cheers!

Pro tip the LC dust caps like part AK-DC-005 are the devil incarnate.

Aside: I can't believe that they charge 50p *each* for these tiny caps, with a minimum order quantity of 20! You get four of them for free when you buy an LC-LC fibre cable.

As you mentioned before it will terminate at ground level, then, back up the wall to the eaves and through the soffit. From soffit to final location internally is about 6-8m which I will run conduit for.

When I had my overhead FTTP install the engineers took the fibre straight from the eaves (hanging point) straight through the wall and put a small internal CSP on entry point and then straight to the ONT, (Saved all the mess outside with it trailing up and down.

If that is possible - but the entry point is low down in a corner. The conduit could be used for either way ...

Both loft have decent ladders - almost stairs going to them, fully boarded and lit, so no potential hazards. I will get conduit/trunking run and then tweak on the day and if a T piece is needed to break out and back in - a 5 minute job.

See how you get on with engineers,

I will not that on my installation it was for an office occupying a third level in an old house (previously the loft) but now fully converted into a room,

I know engineers can be funny about lofts due to risks.

Know too well about lofts and risks - or more exact, my wife does! Hence the reason for decent steps up to them lighting and floors. The smaller one, is where all the comms equipment is - NTE, splitter/filter, patch panels, 4G back up, hub, (previously modem and router), network switch, PoE adapters ... and more. Even has its own power ring with plenty of sockets.

An external CSP is preferred ....

providing a test and access point without the need for an appointment if a fault is deemed external.

Can you request an external CSP at the time of install?

With your previous explanation about high level working too, I will make it easy for them to install and go with what ever they decide is the best way. All I need is the ONT in one specific location - and even then anywhere along a 1.5m length of wall.

Do you know the length of power lead? Is it 3m as with the Smart Hub?

You ought to just have one fitted, as that is the general rule of thumb .. but there are a variety of different scenarios.
