Induction hob for preexisting 4mm T+E

I would use the term common sense other than tradition, out of interest given the info we have, what size cable would you select.?

My understanding is that is a surface install.

No it’s cables clipped to a surface embedded in plaster as detailed in the installation methods in appendix 4

Doh, I just double-checked the oven and it is 2,075 watts not 1900 watts.

Really that won't make any practical difference!

While it is recommended not to put any fixed loads over 2kW on a ring final circuit, a 13A socket is theoretically OK to 3kW but just don't use two heavy loads on a double socket as they are only rated to 20A (not the 26A expected from 2 * 13A outlets).
