im running a new earth to my gas main,can it come off my cu?
The main earth bond to the consumers side gas pipe should come from the main earthing terminal, see diagram by following link below;
If you don't have an MET external to the Consumer Unit you can install one. They are just over £1 for a four way earth block from scxrewfix.
