What you describe, is what I have and it is pvc covered.
I have no concern about the cooker feed as it has its own direct
supply.
To all who feel concerned this is as far as I go with electrics.
Though I did move the central heating thermostat to another room.

This saga all arose because wifey got me a junction box from the HB
shed, as I did not have the time to go to the local trade leccy.
For some inexplicable reason I was reading the instructions that came
with it, as I swigged a cup of coffee.
It stated that the spur cable should be the same size as the circuit
cable .. which made my 6m of 2.5 somewhat redundant !
Hence the questions.
