Oven and Hob wiring options

Sorry folks, but to be clear, the thrust of the question is really about running an oven and induction hob off the one 6sq feed from the board. And again, I'm asking for real life experience of properly experienced and qualified people (like you). I suspect just adding the two rating plates together is easy but wrong or nearly wrong, if you get me.

Yeah, get that ok. The cooker as a whole unit is the first choice. I just happened to mention that bending down to the bottom oven gets to be a pain after a while and they're really into their baking. So a hob and separate oven are a pipe dream, just getting some thoughts together in my head for making sure they go the right route. By the sounds of it, trying to run both off the 6sq will be problematic (there's no rating plates to look at yet, but a sneaky visit to powercity might solve that 😈). This means that I'll have to warn them that a degree of rewiring will be necessary. Its not about cost (primarily) but more about the disruption and subsequent redecoration that might ensue.

BTW, my second post was written as an addendum to my first and when I wrote it, no answers had been posted, so Convolved's post looks like I answered it, whereas I hadn't seen it till now. So, sorry Convolved if it looks like I was dismissing your answer.

Thanks to you both. As usual, come here and get great help. When my daughter got her house a few years ago, with great help on here, I was able to make sensible suggestions as to what she should consider when getting in an electrician. Which ultimately became a complete rewire and moving of the meter. Aahh, they love their Dad and his unsolicited help 😂.
