Ooooh, I don't agree with that.To be honest, once its second fixed and grouted will it look that bad if left where it is.
If Sparkwright is correct then the cable in the bottom right corner could be abandoned.
Having said that, it does not look like it is wired correctly.
Assuming the red and black is the supply, it looks like one of the brown and blues is connected to it.
Could we have a picture showing the connections more clearly?
