Data only switch, I have Copper to house, router connected to extension?

If you do get second copper pair  ‘line’ just for broadband, then arguably the internal extension wiring your current broadband uses is (and always was ) your responsibility , but if (for arguments sake ) a new NTE5 for the EE SoTap is provided adjacent to the existing one , you could transfer the extension wiring from the existing NTE to the new one , so the new EE router can remain in the BT routers existing position at the rear of the property, but this will only service the broadband,  consequently this would require your telephone instrument to be connected to the existing NTE ( ready for when your BT ADSL is converted to PDPL, the phone service only ) , although it’s possible the tech will do some additional work , I doubt it would extend to running another extension cable  and providing another extension socket , once  the existing extension cable and socket are repurposed for the EE broadband , the thing to keep in mind is your existing setup won’t be compatible with two separate lines .

This obviously assumes it is a second line you are getting for the EE broadband , but with the extra info you provide , seemingly this is the solution to your individual ADSL/PSTN retirement problem .

Not sure what you mean when you say you will potentially cancel and get Ethernet laid

@WSH  thanks I do have already one cable cat5 (30yrs ago)  but alas it's not near the master socket, it was setup to handle virgin then NTL. 

Could move to virgin no tech prob but then I'm a Virgin customer and i don't think I can cope 😞 with that. Open reach cabinets on my street are always locked and maintained, the Virgin cabinet linked to my house is left open rain and rubbish get in.

Although this is EE rather than BT , the principle is the same , as far as I recall this wasn’t article I had read previously .

If it is cat 5 (and not 5e) it will only be able to handle 100Mb/s.  That's what the "e" is for.  It's cat 5 "enhanced"  to get it up to 1000Mb/s.

That's what I say about cat 6.  While officially it's still only 1000Mb/s, unofficially it will handle 10,000Mb/s (10Gb/s) at up to 55m, as it is a fundamental redesign.

Could he use old NTE5 for the new BB line keeping the internal wiring the same and router at back of hose and push current line into NTE5 box for telephony. I would lose telephony at the back but router would be ok and no change to internal wiring.

OR could you do the switch at the exchange?

If I get ethernet run from near the master socket where the fibre has to enter (terraced house) run to the back office I future proof fibre regardless of supplier of Fibre.

No one can say what will and won’t be considered, ultimately the installer will decide this , although it’s entirely possible the installer will have no prior knowledge of the rationale behind this , or even know of the existence of another working service , until you tell them , the instruction they have may simply be to provide an EE broadband only service and that’s what they will do , and nothing but that .

I don’t know what you mean with this  statement 

If I get ethernet run from near the master socket where the fibre has to enter (terraced house) run to the back office I future proof fibre regardless of supplier of Fibre. 

There is no fibre (in this context FTTP or FTTC ) but another copper pair service , so an Ethernet cable is of no use , if you provide an Ethernet cable what do you expect to connect with it ?, if thus is with an eye to the eventual provision of FTTP , so you can have a router located in a different location to the ONT , then fine , but it’s of no use until then .

As stated my suspicion is the tech will expect to fit a NTE somewhere pretty close to where the the external cable enters the property ( are you served overhead from a pole or underground ?) , the tech will expect the router to be pretty close to the NTE they fit .

I presume your router staying where it is more important to you than  the telephone instrument remaining  where it is , hence the suggestion to move your own extension wiring from the old to new NTE socket , the tech may move the existing line onto the new NTE and put the new line onto the existing NTE  if that’s easily accomplished (because the NTE’s are side by side ) , but you won’t know for sure until the installer is onsite…but moving the extension wiring achieves the same result.

@iniltous You are correct and put it much better than I with

"if thus is with an eye to the eventual provision of FTTP , so you can have a router located in a different location to the ONT , then fine , but it’s of no use until then"

I have hyperoptic? installing locally. I've stuck with BT because of my home office needing router at the back this and PTSN shut down is forcing me to get a move on and get ethernet installed. I could get Virgin with no wiring changes but just can't face VirginMedia.

Again you are spot on

"I presume your router staying where it is more important to you than  the telephone instrument remaining  where it is , hence the suggestion to move your own extension wiring from the old to new NTE socket , the tech may move the existing line onto the new NTE and put the new line onto the existing NTE  if that’s easily accomplished (because the NTE’s are side by side ) , but you won’t know for sure until the installer is onsite…but moving the extension wiring achieves the same result."  agree

Thank you very much for taking the time to post its been very helpful even when I've not been as clear as some.

Got to get some sleep
Good night.
