all I have been able to find out so far is that there are changes to the bonding and that the bathroom light will need to be placed on RCD side of split load board and on its own circuit.

Socket in bathrooms ; yes at a distance of 3meters horizontaly from the boundary of zone 1 & on a 30mA rcd (but then every circuit in the bathroom will have to be on a 30mA rcd any way (that'll be lights spured of ring via a 30mA fused spur on bathroom refits).
Zone 3 will be gone & supplimentary bonding not required so long as mainbonding is in accordance with part 41.

Cables in metal conduit; Cables in a chase less than 50mm deep will need 30mA rcd, cable still must be in safe zones. No mention of earthed metal conduit unless outside of a safe zone I would think.

All the info you want is here

There are also extra special location sections included in the 17th edition, namely marinas and camper vans, as well as exhibitions. The layout is going to change so that inspection and testing is now section 6, and special locations or installations is section 7.

The zoning is changing not necessarily to allow sockets in bathrooms, but to allow classifcation of rooms differently, ie a bedroom with a bath in it etc, so a socket will be allowed in a bathroom, if it is a large bathroom, and far enough away from any water.. The zoning is also changing underneath a bath, which will allow some equipment to be put under the bath, as long as the bath panel is not removable by hand!

I attended a free NIC seminar at Sandown Yesterday, It is worth buying shares in any company that manufactures RCD's!!
