Lets get this straight... you have 3 rows of lights(?) all 2 wayed from 2 positions. 3 switches at each door or whatever.
You are adding an emergency light?
You need an unswitched live in addition to any switchwire or neutrals to the emergency fitting. Looping through other fittings if nessecery.
You may want to switch this live through a keyswitch... which would mean one of your 3 gangs need to be 4 gang

You could draw out a circuit that you think it needs, and we will see if you’re on the right track

The way it was wired there was 9 cables at the switch 6, 3 core and earths and 3 feeds would it be the 3 brown feeds to the com neutrals in wago and earths in wago plastic fitting. Use the 3 greys going to the light as switch lines and put the blacks in wagos as neutrals. And for the strappers 3 core and earths put the brown in the com. and black in wago and grey in wago. The electrician who wired never told me how he wired it just asking would you know what he did
 
Don’t use black as N . Sleeve the grey with blue

Use black sleeved brown as a swi line

Although some will disagree and use black sleeved brown as perm live and brown as swi line

So if I use brown as permanent black as switched live and grey as neutral is that the correct way to wire the three gang two ways switch
 
Providing all cores are correctly identified it is irrelevant whether you use black or grey as neutral. There is no set rule to this.

For the strappers is it ok to put the black and grey in wagos as long as the brown goes the the com of the two switches

What do you do with black and grey for strappers
Brown sleeving in both to distinguish them as live conductors (switch wires)

You’re not really changing what the previous spark did, so how he wired it is irrelevant.
You are adding one core, supplying an emergency fitting with a permanent live which isn’t there at the moment.
 
No it wasn't, there has never been a 'de neutralising'
I had a thing from the niceic around the time of harmonisation it was a big A4 leaflet about de neutralise black when converting old colours to new. Think several cable manufacturers also produced their own leaflets of de neutral black as well...

It’s even in the brown on site guide I think

Will try to dig it out later

All I have ever seen is advice about old colours and how they correspond to new colours, but not how to oversleeve harmonised colours for different uses.
