BT Open reach responsibility - master socket

[ThriceNightly]

Hi understand open reach responsibility for telephone cable up to master socket

This issue regards Elderly neighbours house
she is only getting 1meg upload 5 download speed. Masters socktet is hallway above front door and looks to be a very old 1960's gpo junction box with bellwire then running to lounge extension socket.

Are openreach liable for upgrading this old equipment at their cost?

Cheers
