32mm sufficient.

If the OP is going through the slab from under the stairs to the front of the property I would personally use the BT duct 56 (54mm) and I would suspect Openreach would also recommend that. I think only putting in 32mm conduit in when you have the chance to put 54mm ducting in is short sighted as the OP may want/need to put other providers fibre cables through it at a later date and I don't think that will be easy.

If the OP is going up and over then there is not much choice really other than settling for the 32mm conduit but I personally would put the Ebay linked fibre cable through as its the exact product developer use when doing new properties although they wouldn't typically put it in a duct/conduit but 'jpm' made a good point earlier in the thread about cable replacement which I hadn't previously considered.

To be clear, I thought the OP meant 32mm conduit internally (as in within the actual dwelling). Which is wholly sufficient for the services from one carrier.

External ducting I agree should really be grey Duct 56 (well for Openreach it should be grey, VMO2 get upset or they used to, pre-PIA, if 'their' duct wasn't green)

I had 3 lots of 56mm ducting installed, from curtilage to 'comms entry' point -to cover all eventualities with Openreach + VM present and accounted for and future Altnets ready in another duct. When you've got the trench open, chucking another duct is pennies to install and future reinstatement with RC and decorative yorkstone paving on top doesn't bear contemplation.

I think we are all getting so conditioned to people asking similar questions to this that the stock answer is put a 25mm conduit in with no sharp bends and make sure its got a draw rope.

👍😀

What I will be doing is laying some internal ducting from the network closet under the stairs to the wall adjacent to where my junction box is situated.

I'll use the supplied BT ducting to give access to the outside of the property from the junction box.

I didn't fancy getting leaving an open entry point directly into my network closet from the outside.

I'm currently battling a rat in our house and the last thing I want is some vermin to find it's way in through an accessible hole.

The linked ebay cable is far too long. I only require a 5-6m cable max.

To add for anyone reading in future:
Conduit tends to have swept bends (sometimes called just bends) and elbows - elbows are too tight and should be avoided. Hand pulled bends are normally fine too as te little ridge from fittings is missing.

Don't get any fibre. As others have said: put in your ~25mm conduit with a draw string, and OR will pull through their own cable and splice it at the CSP. The engineer on the day will be very happy not to have to do any drilling through the wall

The OR installation guy should have these cables with him in various lengths so no need to buy. If you look at the ebay sellers other listings he has other lengths for sale.
