You are not earthing the gas or water, you are installing protective equipotential bonding conductors creating an equipotential zone.
This is to minimise voltages between parts if a fault occurs and someone was touching the two at the same time.

so u agree though spark123 it is required when adding new switch spur to system

yes, ANY electrical work requires that the sparky checks the main bonging ( gas, water, structural steelwork, oil etc etc.. any bit of burried metal that enters the house basically )

cheers for that these jobs are for a boiler contract , fuse boards were replaced in 2006 gas meter approx 3 feet away from board yet not done, water a bit of a stretch but my sparky did it in no time really, these should have been done at time of new boards right?

 

[Spark123]

Yes, before any additions or alterations the bonding should have been checked to ensure it is satisfactory.

 

[ColJack]

if the water comes in as plastic it doesn't need doing..

 

[Spark123]

If the installation pipework is plastic it doesn't need doing, if the installstion pipework is metal then it does.

Is it worth checking the board? If he didn't do the PEB's on a 16th Ed. TT install, there may be no RCD protection either...
