A few years ago BT laid down strict ext wiring requirements on the Engineers for any new/repair work that is carried out on a line. The problem is that it is only lines that there has been work done on since it came into effect. Some lines have been there for many a year and are far below this standard. By what you say your wiring would not pass one of the audits that Engineers have to go through. Getting it brought up to the modern standard would be a problem unless there is a fault or you get work done on the line.
Thanks for the reply, useful and confirms the view I was coming to myself. Well, I need a master socket move in while anyway, so I guess I'll just swallow the charges and get it all done now.
Make sure you ask bt for a "line shift", when your ready for the work to be done as this is a standard price, get them to give you a quote. When the engineer arrives ask him to check all the old wiring and to bring it up to standard within the "fixed price".
But If you get the work done as a standard repair openreach will charge accordingly.
Thanks for the advice, I did indeed do that but mainly because I needed it doing as well
As you say, they ended up replacing all the wiring back to the pole, was a long afternoon for them.
