Hi could anyone please confirm the correct supplementary bonding...

All pipework (bath, shower, sink, toilet, radiators) copper within the bathroom but changes to all plastic beneath the floorboards.

Electrics within the room are:
* Pull dimmer switch to downlights [located in unzoned area]
* Shaver socket (off light circuit) [located in zone 3]
* Bathroom mirror light (off light circuit) [located in zone 3]
* Pull light switch to shower cubicle [located in zone 3]

I don't think any supplementary bonding is required - but please correct me!

Any help appreciated.
