Yes, it has!
The first image is of an old Wylex fuse board with the rewirable fuses, they were common until the 70s and very reliable in use (many are still working today). By the 80s boxes with circuit breakers became the norm, and no more faffing about with fuse wire after a light had gone pop! and taken it out.
Picture 3 is simply the box the new consumer unit (CU, what the fuse box / fuse board became known as one it no longer had actual fuses in it) came in, you can buy them more or less empty (fit your own choice) or sometimes with a common selection of devices fitted.
Pictures 2 & 4 show, of course, your new CU. It shows one with RCBO - these are combined over-current protection (MCB = miniature circuit breaker) and RCD (shock protection) devices as a single unit and so I am a little surprised it did not trip when you got a zap. Each of them has a test button at the top - if you press that it simulates and earth fault (with a lot less pain than poking the wires) and should result in the device tripping.
I guess you never do this test?
You really
should test them! Not necessarily every month, but at least twice per year, say when the clocks change. Best if you switch off stuff that might not be happy with the power going off and back on quickly, like mains powered computers, broadband modems, TiVo boxes, smart TVs, some fridge/freezers, etc., and press each test button in turn. That should result in the main leaver tripping off. You then reset it by pushing the main leaver up again.
Finally remember to put stuff back on once more, especially any fridge/freezers that were powered off!
If any do not trip from the test button then you really should get a sparky out ASAP to investigate it.

Yes, great hair and a nice wet nose, judging by your picture
