It looks low to me, but I'll check.
You're saying that probably the simplest way to do this is to swap all the MCBs for RCBOs, provided they fit in the box? They are about £20 each though.
Yes, I occasionally test them.
I recently had to throw one out because DW (at least I hope it was her, not me) had half-plugged an electric fire into one. The heat generated destroyed the plug and adapter.

OK. So trying my best. If your CU looks like this
a grand total of 1
20 or so per year
it doesn't save any lives from shock. Whether it prevents any fires I can't say.

Does that apply to circuits that only have fixed none user accessible stuff? It sounds like a half baked attempt to stop people putting their fingers in a socket getting killed.

But its definitely not supplied by any circuit protected by the RCD.

Yes. As I said the lights remain on and the fan still turns if switched back on.
Not a good idea - if your ring main trips the rcd you are left in the dark.
Yes
Now that is a possibility. Would explain why it has just started to happen.

Are you suggesting that the qualified certified to whatever professional electrician who did this has screwed up? Well actually his dozy apprentice did most of the actual work 'til he fired him so yes quite possible.
There's no rcd on the lighting circuits.
He is. No rcd on lighting circuits. Personally I think they are as much a liability as a help.
Very limited opportunities to be electrocuted by a lighting circuit compared to a ring main.
Still have one and recently put it into use. Had the lamp holder fail on a metal table lamp. Managed eventually to get a new skirt for it which was also metal. But the lamp was supplied with 2 core cable.
One on the fan unit and one at the wall. I've checked the wall switch and tightened up the neutral connection by a turn or two. I've "instructed" (AKA pleaded with) swmbo to only use that switch for the time being. For reason best known to himself the electrician wired the extension circuits live to the switches whereas the rest of the house is wired live to the ceiling rose.

It does apply to the fixed stuff.
However it's not actually a big game changer in the scheme of things.
The 17th edition more or less made RCD protection compulsory for most new/altered domestic circuits so in 99% of cases this should not be a bigger issue than following the 17th edition regs.
