A little surprised today to find that a request for 6mm heat resistant flex
at a branch of a chain of electrical wholesalers was met with "never stocked
it" and a similar response to 4mm. They called another branch and the
response was "use twin & earth".
Without reference to regs I would have thought "if you can move it without
disconnecting it use flex". You could (still can? ) use pvc flex for cooking
appliances where not in contact with hot parts - so for a free standing
cooker you could possibly be satisfied that the flex "run" was OK how can
you do that for built in appliances?

Just for ease of installation as in getting the double oven into (and out?)
of the housing I'll use flex but is cable allowable? - and how do you get
the oven in without the cable "folding up" behind the appliance?

TLC do a 4mm butyl flex, which they claim is heat resistant and suitable
for use where there may contact with grease or oil.

Is there an issue for normal PVC flex and grease/oil?

You do use T&E and it does need a "fold up" loop behind, so you can pull
the cooker out. The point here, I think, is that you don't pull the
cooker out very often (if ever in most cases), so the cable is not
flexed very often, so it doesn't need to be flexible.

T&E has been used for a long time to connect cookers to the outlet. As the
other post said they don't get moved very often so it is quite safe.

TW&E is ok because movement isn't going to be a common thing unlike say
with an iron. And of course it can stand quite a bit of flexing as it will
get this during installation.

You leave a loop of suitable length behind the appliance for easy removal.
All appliances provide room for this in a standard enclosure.
