Light not working after blown bulb replaced.

[Lumo]

The CU fitted in 2016 seems to have been a good quality total rewire and much of the decorating has not been done so chases are still visible.

The other side of the wall are a column of 3x12 way CU's, first is filled with a main switch and 10x6A RCBOs, the next has 12x6A RCBOs and the 3rd has 3x6A RCBO making a total of 25. one for each light switch in the building, each perfectly labelled with Dymo.

So had the owners asked for this (no nuisance tripping taking out many lights at the same time?) or had they been talked into it by someone who thought it was a good idea?

No idea and I didn't want to hang around too long, especially as one of the cats thought my leg looked like a scrathing post.
