A Red is connected to C Blue
A Black is connected to B Black
B Red is separate and live
C Red is separate and deadI hope this is ok

Hi Michael,

So you need to look at what wires you having going to the switch.

In essence the ceiling rose should have a number of terminals, have a look at the wiring diagram here, from your perspective it sounds like your electrician has wired on switched neutral rather than switched live so the diagram linked is back to front in terms of black and reds and blue and brown.

In which case when referring to the diagram you should connect B RED to position 6 (on the diagram) the pendent Brown\Live connection to position 8

Then position 3 and 4 are your neutral, which go off to the switch, so these would be A Black and B Black

Lastly you need the switch neutral which comes back from the switch which is A Red and goes to position 2 with the pendent blue\neutral connection in position 1.

Test the circuit and check the bulb is work if it is, then we can look at cable C which I assume is part of the ring main or spur to another light.

Let me know how you get on.
