To clarify ........... if you have a 'Managed Install' with the 'Home Wiring Solutions' module, you can have the NTE fitted in your tree-house if you so want. I keep saying, it's your house, you (or your ISP by way of an enticement) will have paid for the wiring module to be available to the engineer should the EU request the NTE be shifted, etc .....
The aspects to the HWS module are :-
NTE5 moved
NTE5 and Extension socket swopped around
Data-extension supplied
HWS not installed
So, when we close our task we have to satisfy one of the criteria above. Obviously, some may try and ride rough-shod over the EU and say it's going where they say its going. Sometimes, the EU will need guidance as to what's best for their set-up. Either way, you have the say on a 'MI' task.
