You should be able to find your natural gas meter in a metal box at the front or side of your property.  

On some occasions we might ask you to provide us with your gas meter number, so we can confirm your address or supply details.  

Your meter number, which is sometimes referred to as a gas meter serial number, is a 10-digit number starting with M8A, M6WA or M6EW. It can usually be found above the usage dial on your gas meter.
