The Customer Choice program offers you the option to purchase the natural gas you use from a supplier other than Columbia Gas. If you choose to purchase your gas from a different supplier, we will continue to deliver the same reliable service, read your meter, perform safety checks and respond to emergencies. 

The prices charged by suppliers are set by a competitive market, meaning there is no guarantee that you’ll save money, but they may offer special pricing and incentives. If you’d like to enroll, shop around and make your Choice. 

CHOICE® is available to all residential and commercial customers using less than 250,000 therms per year.

How to enroll

  1. Review our list of current suppliers below.
  2. Evaluate the offer and compare prices. The Massachusetts Department of Public Utilities lists full current approved suppliers. Suppliers offer various pricing options. Our CHOICE® calculator can help you evaluate pricing options for your gas supply costs.
  3. Consider the contract terms. Many suppliers require you to agree to contract terms, so you’ll want to know contract length and if you can cancel.
  4. Make your CHOICE® by contacting the supplier. If you don't choose to participate, we'll remain your supplier and there is no change in your bill.

Find your current charges

The Detail Charges section of your bill shows your Delivery and Supply Charges. If you participate in CHOICE®, your Delivery Charges will not change but your Supply Charges would change based on the rate provided by your new supplier. Use the calculator and supplier list below to make an educated decision.
