If I'm reading this right the advice given in this thread is incorrect. If both the gas and boiler are external and there is no gas service into the property then there is no reason to bond the gas. Metallic heating pipes/services from the boiler to the property will require main bonding at the point of entry to the building.

Im always sceptical about main service bonding especially on a TNCS system , you loose the neutral at the met , it then sticks around 150 volts down every metallic part that's bonded including the gas pipes as well as causing hell on 3 phase systems ,evry metallic part is live radiators cooker fridges sinks baths if metal taps ,do bond mind religiously

And...................

If the incoming services are plastic.................then copper after that.............then the copper should be bonded.............or words to that affect lol.
Equipotential/touch voltages etc etc ................it's late

Just about to do a CU change at a property. Recently had a smart meter installed for gas and elec. The earth bonding as been disconnected from the gas (and clamp removed) and also disconnected from MET. Any ideas why this is?

Unskilled meter changer? Complain to the company.

PS It would have been better to start a new topic, rather than hijack an ancient 3-year old one.

Thanks. Thought it may be that. Excuse my lack of forum manners.. I'm new to this.

it's possible that there is a fault on the installation and some donut has dissed the bonding. thorough testing before you change the CU is advised.

Its in your interest. New topics get looked at by everyone.
Old one often only get noticed by anyone who contributed to the old topic (assuming they are still alive).
