It doesn't matter who fitted the extensions, they are not covered by the maintenance contract and so they don't get free maintenance.

Not even those fitted by BT? IIRC they also used to charge you extra for an extension.

Covered for 12months if fitted by BT

All work on extension wiring is chargeable unless...

The wiring was fitted by BT and is under guarantee ( 1 year )

The wiring is hard wired and the customer cannot disconnect it, in which case it is disconnected for free or charged for repair.

Well if you do not have a BT master socket you would not have a working phone line. You have a master socket. You may not know where it is though. If you can locate were the BT line enters the house you will usuall find it there.

Simply not true, I'm afraid.

I had a similar problem in my old house. BT came out, Determined a master socket, fitted a new socket with built in microfilter, re-made the wiring extensions and all was honkidory.
All it cost me was three cups of sugary tea and half a packet of digestives!

I have also recently moved house. The incomming BT wire just terminates in a small
"link box" and then a socket is wired to this. I thought that I did not have a master, but found it behind some furniture.
After a few days we lost our 'phone service, no broadband enabled as that time.
BT man connected a tester and left the house for some time and was able to get the line working, this time with no crackles which preceded the fault.
I now have broadband enabled and working at full speed thanks to this "clear line"

He suggested that I should be in no hurry to get a modern test type socket for the reason mentioned in this thread, if my extensions are hard wired and go faulty BT will not charge unless asked to work on my wires.
