Relocate a gas meter, help.

I want to fence up the sideyard, but major trouble is, the gas meter is within the intended fence, at the back of the house.

I could relocate the gas meter to outside the fence, but it is 6 - 7m away. How much would this cost me?

Property is an IP, and I don't know if it is connected to any particular gas company at the moment. So who should I call to get a quote??
