This is the wiring in our bathroom. I've just removed the light fitting that was installed when the house was built and this is what is behind it. It doesn't look right to me. It appears the original fitting was installed using the black, blue and grey wires, but I didn't take proper notice of how as I wasn't expecting to see something that appears to me to be non-standard.

Does anybody have any idea why this would be done in this way? Is it safe? Can I just wire up a new light fitting to those wires?

Thanks in advance.

You will need a multimeter to work out which is perm live (most likely the browns in this case) which is swi live and which is N

Never ever assume what does what

Get a sparks in if you are not completely happy
 
There could be a few reasons this has been done this way. Most likely to do with an extractor fan, since its in the bathroom. Get a qualified electrician in to check it out and advise you on whether its correct and safe.

There is an extractor in the bathroom, so I guess that's the reason here. I think getting a professional in is the best advice, thanks for your help.
 
could always dig up pete 999. he very good spark and in your area.
 
Yes it was a bathroom light and not a ceiling rose. I got an electrician to come in and sort the problem out. It was just a matter of them finding the lives and neutral as pointed out by Dustydazzler.

Thanks again to everyone who commented.
 
I would imagine the Blue is the neutral to the light, and either the Black or Grey is the switched live to the light, the other being the neutral to the fan.
 
If you can get all those wires and connectors inside your light fitting, fine.
If not, you really should put them all in a Junction Box and come out with a short length of flex to the fitting.
