Reference methods for cavity walls without thermal insulation

[Questforknowledge]

Evening all

Just wondering what would be the reference method given for a twin and earth cable in a cavity wall without insulation....I understand with insulation its either 102 or 103 but these massively de rate a cable and so was thinking is it b without the insulation as it acts similar to a void. I'm still learning so just trying to memorize as many scenarios as possible really but look forward to any responses.

There is no reference method for cables in a cavity wall and they should not be installed in a cavity wall .
