Is it permissable to run circuits inside plastic trunking and conduit using correctly sized individual cables, rather than T+E?

Yes.
Thanks! Is it permissable to use stranded cable in place of solid core?
Yes, that is the norm for singles in conduit

Depends what you call stranded, you would tend to use 6491 cable, although flexible it is stiffer than flex which has lots more strands.
Also tends to only be sizes upwards of 1.5mm available.
Not a big fan of singles in smaller plastic trunking sizes personally, plastic conduit yes, providing cables are enclosed fully.

Yeah that. Specially where they take the MT through the coving with an axe!
And run the MT across the ceiling to a big surface mounted backing box with a pendant attached.
They did this to my parents house during the 80's and, because their house had been a flat roofed bungalow when first built, it had concrete floors upstairs.
Dad asked my elder brother if it was possible to sink the cables in to the walls and ceilings and he said yes, so long as there is a bit of slack.
I went up to see them the following week and he had took an angle drinder all round the house chasing the cables into the walls and ceilings!
After he had skimmed over and decorated you couldn't notice anything. LOL
While the answers are yes, there are some restrictions to using single insulated singles in trunking or conduit. The main one being that the containment needs to meet IP4X or IPXXD for ingress protection. This is reasonably easy to do with plastic trunking by careful cutting and use fo the joint pieces - but any but other joins will not meet this requirement.
The harder one is meeting the requirement that the containment needs a tool to open it - that is not as easy to meet unless you are really careful about your joints.
