The reason it doesn't comply is that currently I have no supplementary bonding in the bathroom. However as all circuits are RCD protected this will comply with the 17th as no SB will be required when the new regs come into force
Is it a single RCD protecting all the circuits?

And you think that will comply with the proposed 17th edition?
A single RCD for a dwelling will not comply.
Supplementary equipontial bonding can only be omitted if all the bathroom circuits are RCD protected AND there is main equipotential bonding - which I doubt you have, and I certainly bet it aint 10mm.

Good job too!
Yes upgraded main eb to 10mm and me to 16mm some time ago. I posted this item to get you experienced guys to comment as I value your posts. You could say I was being provacative. Def from a safety view point is not good if all your lights go in the dark and I am aware of this ssue. However, according to http://www.elecsa.org.uk/downloads/public/3382 Factsheet.pdf the following passage appears:
Modified sections
All of the following Sections have been modified to accommodate the regulations
contained in the European HD’s.
701 – Locations containing a bath or a shower particularly the changes from the
16th Edition are substantial:
• Zones 0, 1 & 2 as defined in the 16th Edition are retained. Zone 3 is
being removed. New regulations require all circuits supplying equipment in
the bathrooms to be protected by 30 mA RCDs.
• Supplementary equipotential bonding is no longer required providing the
main bonding of services within the property is in place.
• SELV (separated extra low voltage) socket outlets and shaver socket outlets
are permitted outside Zone 1. 230 V socket outlets are permitted
provided they are more than 3 metres from Zone 1.
Surely in essence my installation complies with bs7671 although not in the spirit?

I've heard a different version of things, so I'll reserve judgement until I have actually read a final published copy of the 17th edition.
Concur!
It won't just come, you know - you do actually have to buy it.
So it's your choice - wait forever or buy it whenever you want to.
BTW - apart from SELV & shaver sockets in Zone 2 (which may be allowed anyway), pompeygit's list matches the one in the 17th...
