If you use natural gas, you will likely have a contract with a gas retailer for the supply of natural gas to your home or business. Generally, Vector charges gas retailers. Gas retailers then typically bundle the cost of our services along with other costs. These other costs being the purchase price of the gas, transmission services and metering etc. Gas retailers then usually provide you with one monthly bill. Retailers will choose how and when Vector's price changes above are passed through to their customers.
