Equipotential bonding

[Roddders]

I have been told my gas pipe to the meter needs an earth bonding. Where does this run from? Does it need a connection near each appliance then run on and connected near the meter. I have been told it needs to be clipped within 600mm of the gas meter, is that correct?

From consumer unit earth bar or met take 10mm earth cable to the gas meter and connect to the gas pipe using a BS951 earth clamp.
It must be connected customers side of the gas meter and before the pipe branches off around the property, and yes the connection does have to be within 600mm of the meter.

just out of interest... why does it have to be on the customers side of the meter instead of connected 'directly'?

Four reasons

- everything upstream of the meter belongs to NGT or SGN or someone, not you, and you are not entitled to attach to it

- The gas meter is removable and is replaced periodically. As soon as the old one is removed you would lose continuity. The pipework might be replaced or altered and plastic pipes may be used

- the meter is not intended or warranted to provide electrical continuity. The joints in the pipe will have rubber seals (or jointing paste) in them.

- you are attempting to bond everything inside your house, you are not responsible for the gas pipes in the street.
