Hi Sorry read the post wrong,I would always install 10mm main bonding whatever supply.

FWIW. On surveying a potential job I ALWAYS check to see if there is the correct bonding (10mm) in place before giving an estimate and then advise on an upgrade if required.
What do you do if you advise them of the upgrade to gas and water supplys and they dont want to pay for you to do it.
Do you leave the 6mm bonding in place and continue with your work, just adding a note on the cert you recommend a 10mm upgrade?
Or tell them before you start that the bonding HAS to be upgraded before you will carry out ANY alterations or additions?
I spoke to the niceic on this very subject as i had the same issue with one of the jobs i was using for my assesment.
Basically, if tns or tt you can use the adibiatic equation to prove what size conductor you can use for your bonding
