I'm fairly sure that when this house was rewired that the cable

recent discussion here has discussed 10mm and even 16mm.

Has the standard changed over the years?

There is probably a wider availability of more powerful cookers (or hob
/ oven combinations) than in the past.

However 6mm^2 is a fairly common choice in most cases. Note also that
you can apply fairly generous diversity adjustments to cookers in a
domestic situation, and that tends to lower the design load quite a bit.

Thanks.

Interesting Wiki, especially the chapter on electronics repair.
