Not 100% sure I agree with this.
you could find the fault, fix it and replace the MCB with a RCBO for all the lighting.
How old is the property ?

This is a VERY POOR EIC if it is meant to reflect the photo you posted.
When was the CU changed?
on the same date as the EIC (June 2020)
Fair enough. I did say 'hazard a guess'.
He could but what if there are two cables in the MCB - upstairs and downstairs?
1 x OCPD = 1 circuit
waiting for the tenants to move out so that we can rewire the whole property. However, they have been looking for alternative accommodation without success. And I do not think they will move out soon as thier daughter with her 2 years old son just got divorced and moved in with them. however, I was told is not a serious issue...
there is only one cable in the MBC for both the downstairs and the upstairs light. would that make it difficult to trace?
this is the inside of the CU. the 1.5mm wire on the far right next to the main Switch is the only wire for both upstairs and down stairs light. one of the ways I would start Tshoot the issue is to move from the far right MCB to the fifth from left RCBO, switch all then lights off and then switch them one by one and see which one trip the RCBO. do you think that would work?

What does the EICR say about the electrics?
Leave it alone and employ somebody competent
it only feeds the one light bulb under the stairs where the meter is
Yes, the reason it stops RCDs tripping.
You are obviously not familiar with the borrowed neutral on some stair lights.
Ok, my thoughts were incorrect.
