How to replace old white phone extension socket with new chrome one?

Hi

I want to replace the old white plastic extension/slave phone socket which as you can see from the photo sits proud of the skirting board, with a more decorative chrome one.

The box is easy enough but in terms of the faceplate, how does it work? Do I just undo the 4 screws that seem to be holding the circuit board in place and fit it to the new socket plate or do they come preloaded with the circuit board and the connectors (sorry but when you look at the chrome sockets on Srewfix etc they only show the front, so I've no idea what's going on at the business end!)

Thanks again!

 

The new socket will come with its own circuit board and terminals built in. So, the orange wire moves from terminal 2 on the old socket to terminal 2 on the new one. In a similar manner the blue wire moves from terminal 5 on the old socket to terminal 5 on the new one.

The screwfix description usually says that it comes with 'Screw terminals'
