Sorry, that’s nonsense. Either individual conductors to gas and water, or one single, continuous conductor serving both.

Section 54
It is not nonsense, protective conductors have got to be continuous.
It is up to you if you want to use one conductor for water and another conductor for gas but continuity is key no breaks at all.

Right - this isn't a reg, its guidance
Most people don't have the Guidance Notes ......
If the IET intended this to be a reg it would be in the big book
Thanks not got GN 8 does it say anything about seperate conductors being no compliant? because I think the post saying it is, and a single conductor is the best practice is incorrect.

Hit, nail and head and rather proves my point I think.
I would have thought that you would have it Pete!
A single conductor to each service is the ideal situation, however to use a single conductor to one service and loop it on to the next service is totally acceptable.
There is a suggestion in GN8 that a looped service should be unbroken to avoid the chance of a disconnection at the first service also causing disconnection at the second service.
Though it is interesting to note that this will only be applicable if someone carefully undoes the wiring connections, in which case they would probably be careful to reconnect, rather than just snipping the conductor.
However where the conductors are not looped there is no suggestion that they need to be unbroken and in many cases will often be jointed several times before they arrive at the MET particularly in large installations.

You can argue as much as you want and dismiss advice here.
The op who posted wanted guidance and if he is going to sit his AM2 and does that he is going to fail.
The issue of you not having the guidance note is your problem ,you can choose to refer to as many books and notes as you wish.
The Guidance note 8 (Earthing & bonding) is an exampanded form ofchapter 54 of BS 7671 2008 amendment 3.
All information in their is correct and binding.
