new flat - secondry sockets not working - can I change that myself?

[#1]

Hi All,

In a new flat, master socket in cupboard in hallway but several other sockets in other rooms. The master works perefectly - dial tone and internet - but all other sockets seem to have no connection at all.

Is there something I can do to change that? I've taken off the faceplate from one of the sockets to show the wiring and link it here: https://imgur.com/a/EuT12ZQ

Can anyone advise?

Thank you!

A photo of what's inside the master socket might be more revealing.
