Replacing metal plug faceplate

VT41

The right switch only intermittently works and needs to be pressed around midway to make it work

I believe I need to replace the faceplate with a new one. 

Is it as simple as that? Are there particular faceplates I should get?

Note- there is another plug socket to the right a little further across that doesn’t work one on the right  side. The left of that is fine

You just need to replace the whole socket with one of your choice. 

The other one may also need replacing, but worth checking the wiring first.

It's a simple job, but if you don't know what you're doing, or how to turn off the power, get someone qualifies to do it.
