Light switch socket

[Pmont66]

After decoration needed to change light switch as it had stopped working. Heating engineer changed it over for us! But since it was changed over all of the lights out side and in on the ground floor work by having to have this one switch on! There is another light switch in the same room, can turn on and off from either. This one has not been touched just the one in the pictures. We stay semi rural and trying to get an electrician to come for one light switch is proving to be difficult. I have attached pictures if someone could advise where the wires are supposed to be I would very much appreciate it.
Thanks in advance for any help/advice given

This is what happens when you let a heating "engineer" loose on electrics.
I suspect he's got two of the brown wires mixed up, but it's difficult to suggest which from the pics.

Hi thanks for the reply. I can try take better pictures if that is any help? Been like this for over a month trying to get an electrician to visit!

There is a brown wire connected to a choc block with a black wire connected to the other side. Is this black wire the one that goes to the switch?

Hi

Not sure. This is the way it was left apart from being screwed on.

the wire that's loose just now came loose when I moved switch.

Not sure if these are better pics.

Is there another switch that controls the same light as this switch, I.e. 2W switching?

The wire I thought was black now looks brown in the new pics.

Hi

Yes one on the other end of room, it hasn't been touched. The wire that's loose is more black grey. Then there is the black wire attached next to it. Then 2 brown attached above to same grey block on switch. Inside there is 3 blue wires attached to white block. 2 brown attached to clear block. Yellow and green attached inside.
I appreciate your time and patience

TURN THE MAIN SWITCH OFF AT THE FUSEBOX/CONSUMER UNIT.
Unscrew the other switch from the wall and take a pic of how it is connected.

Unscrew the other switch from the wall and take a pic of how it is connected.

They are 3 brown wires one yellow green in case pic isn't clear

I suspect two of the browns are brown sleeving on top of a grey wire and a black wire. It's usual practice just to slide on 10mm of brown sleeving to identify a wire, not completely oversleeve it!
TURN THE MAIN SWITCH OFF AT THE FUSEBOX/CONSUMER UNIT.
Right, the brown that is part of the cable with a grey and black goes to 'com' on the switch. That is the only wire that should be in 'com'.
The black goes into L3 and the grey goes into L2.
That should leave three browns unused. Two of these go into L2 and the third into L3, but I have no way of telling which, so you'll have to experiment.
Don't tighten the screws of L2 and L3 fully between tries, don't forget to tighten them when it's sorted and TURN THE MAIN SWITCH OFF AT THE FUSEBOX/CONSUMER UNIT and back on again between tries.

Thanks for all your help
