Can I remove gas earthing?

Ericsson · Apr 24, 2023

We had our gas disconnected last week and the meter removed. We need to start removing the redundant gas pipes in inside the property. There is earthing connected to the main gas pipe 1 meter after it enters the property. Can we go ahead and remove all the redundant gas pipes including the earthing or do we need to take the earthing into account somehow?

Does the earthing (bonding) loop on to anywhere else?

Yes however not in a way that looks particularly safe!

Sorry, I meant where it connects to the gas pipe.

It goes through the floorboards so I can only see one end of it. I am planning to lift the floorboards so will try and take more photos.

From your photo, you wont know which one of those green/yellow wires is the gas bond...
One from the main supply cable, one going to water maybe? What are the others?
Leave it connected, as disconnecting the wrong one could cause an issue later on.

If the gas pipe no longer enters the building, and you're removing the pipes within the property.... the bonding cable isn't doing anything..... there's no harm leaving it coiled up somewhere under the floor....
Likewise, there's no harm in removing it systematically from the gas meter position back to the consumer unit as you uncover its route by lifting boards etc.

However, as @DPG mentions in #2, make sure the gas bond doesn't then loop from the gas pipe onto the water pipe or other service... or you'll be disconnecting both.

I don't think it loops with anything else. The end of the earthing cable goes back to the fuse.
Outside they installed this where they removed the meter.
