External light wiring: What has been done wrong here?

[Zoo]

Please take a look at this picture of the wiring on an external light on my house.

View media item 98563
The light doesn't work and I have no idea if the wiring is correct or not?

I've tried Googling for an answer but everyone seems to have their own opinions and I don't know who to trust?!

Any help will be much appreciated.

We need a bit more information than you have given.
Some picture may help!
Has this light ever worked?
If so has there been any recent alterations to it or any work carried out in the property, that could have affected the working of it?

In case the first image is not visible for some reason. Here it is

Need to see the functional switch wiring also, plus a test meter is required to identify what the cores are doing.

Why have you (apparently) used Black for the Line(live)?

Thanks for the responses. I didn't do any of the wiring myself and I do not have an understanding beyond; brown(live), blue(neutral), green/yellow(earth). Assuming that is correct. The colours coming out of the wall (grey,black, thin brown, thick brown) only confuse me. My electrical experience is literally; I once wired a plug, that's it!

I have the sense to not experiment without advice and I can see you guys would require more information/testing to advise properly. I am not comfortable unscrewing anything internally for fear of damaging finished walls etc so at this point at might just call a local electrician.

Thanks anyway.

It depends how the electrician wired the other end of the cable. We would just be guessing to be honest. Educated guess, but a guess all the same.

Can you take a photo from behind the switch plate that controls this?

It is wise to contact a qualified electrician, but the only reason that you could damage wall finishing by removing the switch plate. Is if a lazy idiot did the decoration and painted/papered the switch plate to the wall.
Or even possibly plastered or tiled in!!!!
