Can I run my own internal fibre from the outside wall box?

[dw5]

I'm currently having underfloor insulation installed on the ground floor and will soon be installing the floor covering.  I've taken the opportunity to run the existing copper telephone cabling beneath the floor.

I'm considering moving to full fibre in the fairly near future and wonder if it's worth me buying and running the fibre which will be between the outside wall junction box and the terminal unit inside the house in advance.  I'd rather the cable runs under the floor and that won't be easy once they're back down.

I guess the question is, can I buy 15m or so of the BT approved fibre at a reasonable cost and would the BT engineer be prepared to use it?

I can always just install a draw-wire but running the fibre itself seems more foolproof.

Thanks

The answer you are going to get, is no, as Openreach would only use their own fibre.

As for a draw rope in a conduit, that may be possible, but you are not going to know where Openreach are going to make the entry point.

I am sure you will get a reply here from @iniltous , who knows about these things.

This is the kind of Fibre Cable Openreach currently use for the connection between the CSP and ONT.

As @Keith_Beddoe says, you can't run your own fibre.

If you know roughly where the incoming fibre cable will reach your property, you can run some conduit with a draw string, and the chances are the installation engineer will use that.  I did exactly this for my FTTP installation a few months back, and the installer was very happy to use it (made his job pretty easy, tbh) - allowed me to get the ONT in the internal cupboard I use as a comms room.

I used 20mm flexible conduit from Screwfix, but I think you could get away with narrower.

Thanks all for the replies.  I'm going to take the advice and run a conduit under my floor.  There's only a short area on the front of the house where the fibre could come up.

Out of interest, if Openreach can't use the existing underground conduit for the new fibre, what's their preferred means of crossing 8 feet of front garden?

If your home is ducted ( so from the footway box to your house wall there already is a duct ) but this turns out to have a stoppage, then that stoppage is located , excavated and repaired, if a house isn’t already ducted , and a new Toby box were provided at the curtilage before the order was raised , then a trench for duct made across the garden to the house wall from the Toby box , if no Toby box , a duct provided from the footway joint-box to the house wall crossing the garden at a convenient place , staying in soft surface ( grass ) where possible.
