Running sub mains in T&E is becoming increasingly problematic.

Always thought SWA was a superior choice, better mechanical protection and lower R1+R2.

I personally never use twin and earth in flat submains, smacks of cheap builders wiring.
I always use swa

Using SWA just makes so much more sense. Peace of mind that the jobs done right in my eyes. ??

Hi Buzz ,thanks are the cables buried, surface or encased in earthed containment, (trunking etc)

I've only ever done this in SWA but you do end up with the problem of presenting it neatly into a domestic CU downstream.

It is likely that it was compliant at the time of installation, a code 2 would only be appropriate IMO if it could be ascertained that there was a real possibility of disturbance or mechanical damage. If not I would apply a code 3.

it could be argued that the cable runs themselves are covered by the 'skilled persons' get-out clause because no-one except a contractor instructed by the landlord is going to be drilling through walls in communal construction. Maaybe.
