For a standard domestic Install, split board with 2x Type AC main switches.
No PV or Car Chargers should this be a C3 or C2?
Thanks in advance

The average consumer will have no idea what sort of RCDs they have.
Agreed
They know even less about BS7671 or BS1363
They will be happy until something does happen, it's put forward that the RCD didn't operate and that might have saved a life ... and then all hell will break loose; and it will, of course, be our fault !
Agreed
Therefore Product specification and/or requirement need to deal with it for the UK. Very rare that a consumer will consult BS7671 or BS1363 while to shop on Amazon (other retailers are available)

Not sure how the product standard could sort out some of the issues (e.g. incorrect type of RCD/RCBO, unidirectional RCD/RCBO, and single-pole RCBO)?
product standard for balcony solar could mandate an RCD plug for example.

I think that's missed the point ... the RCD protecting other socket-outlets could be:
1. Blinded if it's Type AC
2. Permanently damaged by the presence of a source of energy on its load terminals if unidirectional.
THe danger is then a fault on other appliances connected in the same circuit. In the case of item 2 above, this will persist even after the plug-in generator is unplugged ... so I'm not sure how this could be addressed by the product or its instructions for use?

Neither will yer average politician.

Given that in-service RCDs have a general failure rate something in the order of 7% ... aren't we in that situation anyway?
Likewise when the householder admits they haven't pressed the T button in the last 6 months...

Are we sure this statistic still current? Yes, I'm aware that, what is now quite a long time ago, there was a study that indicated that statistic ... but there have been a number of developments in product standards for RCDs over the past 25-30 years.
In fact, this site proposes 97 % reliable, with an improvement if the devices are tested regularly: https://www.electricalsafetyfirst.org.uk/guidance/safety-around-the-home/rcds-explained/
Compare that with certain unidirectional devices that are known to fail 100 % of the time if they are operated (including by pressing the test button) with a 230 V source connected to the load terminals ...
aren't we in that situation anyway?
So, no I don't think we are.

I really struggle with that. I suppose that it means that if RCDs are tested and are found to fail, they are replaced, which apparently improves the reliability overall.
3% failure rate. What would you accept for the brakes on your car, for example?
