Hi guys
Would appreciate your comments on the following.. I am currently involved in the refurbishment of a building with 2 service heads (both in use) but only one gas intake and one water intake. What are the main bonding requirements in this situation? I am assuming both MET's require a bonding cable to the gas and water intakes? Many thanks in advance.

Without eyes on this install, it's difficult to assess, use the MET related to the service head you are relying on???? Anyone??

You either link between the two METs, or keep the earthing and bonding for the two installations separate.

1 to the gas, 1 to the water?

Seriously though, why is there 2 electrical services if its only one property? Speak to the supplier and see if it can be combined to just one.
Separate supplies to separate buildings? How does the installation itself have the electrics separated?
If one electrical supply serves the building with water, and the other doesn't... then take the bond from there.

Multiple incoming supplies should have their earth's linked subject to the DNO's requirements.

Main bonding from each MET to the point at which services enter each installation.

Thanks for suggestions guys. Building looks like it was at some point 2 separate dwellings converted to one. The service heads are on opposite sides of the building.
