Does this exist? 900mm wide electric hob with 2 x 13amp plugs (UK)

Sorry, you're suggesting that the hob had 3 individual plug sockets for power? That seems highly irregular,

Something like this ? https://ao.com/product/pug61raa5b-bosch-series-2-induction-hob-black-92955-39.aspx

Sounds odd to me too and surprised it would be ok to use given all three are likely to be going into the same socket/ring

Can it be three-phase domestic power supply with sockets connected to different phases?  I've seen an old cooker with a three-phase plug where hotplates could be wired to different phases if needed (to distribute big power between phases and to not overload single phase).

YIKES!  and not on 13amp BS 1363  plugs / socket

Why not? What most of us have is one phase of 3-phase supply. The next house can be on a different phase of the same 3-phase supply.

If a house has 3-phase supply, that is possible, there can be socket circuits connected to different phases.  The only odd thing is having three sockets in one place each belonging to different circuit/ring.

And we don't know what exactly this old hob is, but generally any primitive hob is just a combination of several hotplates with independent switches.

Just checking if we are talking at cross-purposes....  are you saying if a house had a 3-phase supply and had final circuits on each phase with 13A-type sockets than you don't see a problem with running a 3-phase appliance with each of the 3-phases individually connected via a 13A BS1363 plug?

Also, if the house has a 3-phase supply, why would someone bring more than one phase to a kitchen island if all that were fitted were BS1363 socket outlets - if you've got a 3-phase supply then why not use a 3-phase socket and plug instead?  Putting the safety question on hold for a moment, it doesn't seem to be particularly economic installation method?

Well, not sure about, say, a 3-phase AC electric motor that, by it's nature, cannot work from a single phase, but I don't see a problem with connecting independent hot plates of a powerful hob to different phases if internal wiring allows this. Just imagine that it's a combination of three single/double-plate desktop cookers or three domino hobs.

Also, if the house has a 3-phase supply, why would someone bring more than one phase to a kitchen island if all that were fitted were BS1363 socket outlets - if you've got a 3-phase supply then why not use a 3-phase socket and plug instead?  Putting the safety question on hold for a moment, it doesn't seem to be particularly economic installation method?

I don't know why - and it was a question/hypothesis, not a statement. AFAIK, in domestic environment with 3 phases there have to be 3 CUs. If there was one socket already in place then possibly it was easier to run two normal extra radial(?) circuits from two CUs (or other rings) than a new 3-phase cable connected to all three CUs.

As I said, I don't see any problems with plugs and safety.
