just about to change a light fitting - taken off from ceiling and there is one green and yellow wire and about 6 black wires ?

Martin,
Keith is describing the loop in wiring system,
Keith, firstly connect all of the red wires together(permanant supply), then connect the black wires from power in & power out ,these are the neutrals, the black wire left from the switch wire is the switch live , this needs a red marker on it to indicate that it becomes live when switched.
So the light light fitting connects as follows,
Brown - sw live (black with red marker)
blue - to black(the 2 black wires -neutral)
Earth - green/yellow (if fitted)
