Openreach are shortly coming to investigate my slow broadband. I have a very old master socket. Are they likely to fit a newer master socket?
It depends on who you get, contractors might not, but BTOR Engineers probably might if you ask nice.
But there is a very good chance they will if they are coming out due to speed issues, I know when we had them out here nearly every few visits they would replace it, and do loads of tests to find out the cause for slowness.
