Including turning all the MCBs off and then trying to turn the RCD back on?

Yes
32A MCB two from Main isolator, between up and downstairs lights.
Why is that open (down/off)?

Which MCB protects the distribution circuit to your second board then?

So to clarify:
All the electrics are off at the second(first picture) consumer unit, but every thing else is on from your main consumer unit(second picture).
The problem could lie in a number of areas:
Ideally you need some test equipment to test for voltage, this would be a great help to elimination locations and electrical items, this will determine at what point the fault starts.
If you feel confident enough, I would isolate system, then remove cover of main consumer unit and check both live and neutral conductors are not loose from the MCB indicated in your last picture.
If that is okay, still under isolation check that the tails at the second unit are also secured and not loose.
I would suggest that you either buy or lend, a multimeter or voltage indicator to prove the installation is dead prior to working on it.
If you can get a voltage indicator or multimeter, once system is back live and the fault is still occurring then you need to start testing for voltage at the second and main units.
It is possible that the RCCB or the MCB has failed and need replacing.

Yes I think the best option is to get an electrician in. If the MCB was to have been tripped/blown would it need replacing?

One of the MCB's has tripped - which circuit does that control?
If it is not the one linked to the outside which one is it?
Try the test button on the garage trip outside first see if it trips off.
That inside crabtree trip is also showing a red indicator possibly thats tripped to the middle if they do that, you could press the yellow test button see if it does anything, make sure nothing important like computers in use as it may turn things off, then push it down and bring back up again.

All he will probably do is switch that 2nd mcb on first, you could try that, you can always turn it back off again, but at least you will eliminate it
If that had tripped might he not have noticed the lack of shower, cooker, and sockets in the house by now?
