So how common is TN-C-S with a single PEN in new build?

I'm sure Adam can add more datapoints than everyone else here combined.


I am also sure that I am not sure. New builds in Epworth that I have
just worked on (one street). Half are TN-C-S with a 100A supply and half
are TN-S with a 80A supply.

However I would say that 80% of newbuilds I have worked on in the last
20 years are supplied with a single core concentric cable.
