We have been having trouble with some of the sockets (apparent intermittent connection). This sometimes prevents appliances from working (intermittent power) and also appears to be causing issues with the ethernet powerline adapters we are using. I had an electrician take a look and he insisted there was only one faulty socket which he replaced and tested by plugging in some kind of tester. He didn't actually check ALL sockets in the flat. Anyway, the problem has persisted and I know we need to replace other sockets which I believe I can manage myself. However, I wanted to check if there are other issues.
I acquired a Kewtech Loopcheck 107 plug-in socket tester. This has identified sockets with an intermittent fault when you wiggle the plugged in tester. But it also shows other things for all sockets:
Loop test: amber (between 1.8 and 92 ohms)
RCD check: depressing this button for a few seconds should trip the RCD. Nothing happens, but them I discovered on checking the consumer unit that there does not appear to be an RCD (see photo).
Is this anything to be concerned about?
