Well purism would be having OR do the job, rather than doing it yourself even with 'approved' materials. Which was open for debate from the opening post

Indeed, I am past that, rightly or wrongly!

I want to use the proper cable, as you say as OR would use.

It looks like that would be either spec CW1308 or CW1128. The house was built 50 years ago, I cannot vouch to any of the history up to the master socket, just what I see.

Black outer sheathed cable from outside with white and orange solid copper conductors. Each wire insulation measures 1.5mm and the copper conductor itself measures 0.9mm. Both wires are wrapped together in a paper like material. About 1M into the hall, this cable is connected via jelly crimps to 4-pairs twisted 0.5mm tinned conductors. I scratched the tinning back to reveal a copper condustor.

So, I think CW1308 spec cable is required, something like this from TLC.

Cheers

Yes. Although the last lot of 1308 I got from them [admitttedly several years ago] had rather baggy outer sheathing which didn't look right.

Thanks, I'll just hand it back if it looks rubbish. I only need a few meters, say 10-15M, any other places that supply such short lengths, i.e. cut by the meter?

That looks good, the standard I believe Openreach uses is CW1308 and the TLC link says solid copper conductors which is what you need.

When you get it just double check the label to ensure it doesn't say any anything about CCA or CCS (as explained in my first post in this thread)

That sounds like *possibly* a direct in ground single pair UG feed … does it appear behind a plate, quite possibly in the entrance hall ?

No, well not anymore. If I remember, when I first had broadband installed, BT engineer came and upgraded a new master socket, replacing an old screw terminal oval/rounded box - something like BT52A shown here. I could be very wrong about this !

However, it does come to our front wall undergropund, rises up the wall a few inches, then hits the hall juction box I described in my first post, i.e. simple BT junction box (no terminal inside) and wires connected with the jelly connectors, leading to the master socket.

Thank you, will do.
