Electric oven socket not working

Most consumer units only have one RCD and occasionally two, never seen one with a dedicated cooker RCD, but of course I stand to be corrected.

RCBOs have a seperate RCD for each individual circuit

Our 2004 built house has a breaker of some sort, maybe RCBOs, for each circuit, including a dedicated circuit for the oven.

From memory, there are maybe eight or nine in total. Upstairs and downstairs lighting and sockets are four. Then there is oven, alarms and a few others,

If the oven has a fault and triggers the breaker, it only affects the oven.

If a downstairs bulb triggers the breaker, it only affects downstairs lights.

etc.

I'll have a proper look tomorrow but I think that is reasonably accurate.

The breakers are most likely MCB's which replaced the old style wired fuses, MCB's are rated in the same way as the old fuse wire used to be. The breaker on my oven is 30 amp, too low a rating will result in the breaker constantly tripping when the oven is using too much power. You also get consumer units where one side is protected by a single RCD and the other side with a basic on off switch, the non protected side is for the likes of fridge freezers or other essential circuits where a nuisance trip of the RCD could be disastrous.
