How to Switch Natural Gas Providers in Georgia

Illustration: a gas meter with two blank hanging tags, one slightly in front of the other.

Switching natural gas marketer in Georgia is an account change, not a service change. No one comes to the house, no pipe is touched, and the gas is identical. What changes is the company that buys the gas on your behalf, sets the price and sends the bill.

That is worth stating plainly, because the fear of an interruption is the main reason people stay on a rate they would not choose today.

What actually happens

Atlanta Gas Light has been a pipes-only company since Georgia deregulated the retail gas market in 1998. It owns the mains, the service line and the meter, it reads that meter, and it is who you call for a leak. Marketers own none of that. They buy gas wholesale, set a per-therm rate and a monthly customer service charge, and bill you.

So a switch is a change of supplier on one AGL meter. AGL keeps delivering the whole time.

The one date that matters

Georgia switches on a monthly cycle tied to the meter read:

There is no expedited option. If you sign up on 3 October you start 1 November; if you sign up on 25 October you start 1 December.

What to check before you sign anything

Your current contract. This is the only step that can cost real money. A fixed-rate plan usually carries an early termination fee. Among the standard 12-month fixed plans on the Georgia PSC’s September 2026 chart, the filed fees were $100, $150 or $200 depending on the marketer, with one filed as “up to $100” and one with none at all; other terms on the same chart ran as high as $300. Variable month-to-month plans normally carry no fee. Find out what yours is before you enroll, not after.

If the fee is $150 and switching saves you $60 a year, leaving today is a bad trade and waiting for your term to end is a good one. Our tables show the filed early termination fee beside every plan for exactly this comparison.

The rate and the service charge together. A marketer with a lower per-therm rate can cost more per year once its monthly service charge is counted. In September 2026, Gas South filed $0.690 per therm against True Natural Gas at $0.691, and still costs more across a year because of the service charge. Compare estimated annual cost, not the advertised rate.

Whether the advertised rate is the filed rate. Marketers routinely advertise below the rate they file with the PSC, usually with a promo code and conditions attached. Those offers can be real and claimable, but they are not what is on file, and the conditions are where a deal falls apart on the phone.

The term. A 12-month fixed rate is only fixed for 12 months. Find out what happens at the end: most plans roll to a variable rate, which is the single most common way a good deal quietly becomes a bad one.

How to do it

  1. Find your AGL account number on your current gas bill. It identifies the meter and does not change when you switch.
  2. Check your current contract for an early termination fee and an end date.
  3. Compare plans on estimated annual cost, not the headline rate. Every marketer’s filed rates are in the current comparison.
  4. Enroll with the new marketer, by phone or on its website. It notifies AGL. You do not contact AGL yourself, and you do not need to cancel with your old marketer: the enrollment does that.
  5. Watch for the changeover date. If you enrolled by the 19th, your first bill from the new marketer covers service from the 1st of the next month.
  6. Keep your final bill from the old marketer until you have confirmed any termination fee is correct.

What does not change

The gas, the meter, the pipes, the emergency number and the base charge. Every marketer’s gas arrives through the same AGL pipe from the same interstate system. AGL’s delivery charge is passed through on whichever bill you get, identically, which is why our annual estimate adds it to every plan equally rather than letting it hide the difference between marketers.

Smell gas? Call Atlanta Gas Light at 877-427-4321, then 911 once you are safe. That number is the same whoever you buy from, and it does not change when you switch.

Who cannot switch

Choice applies only on Atlanta Gas Light’s system, which covers most of Georgia including metro Atlanta, Savannah, Macon and Augusta. If you are served by Atmos Energy (Columbus, Gainesville and parts of west Georgia) or by a municipal gas system, your territory was never opened to competition and there is no marketer to choose. Your bill will say who delivers your gas.

Customers who cannot get a contract because of credit history are served by the regulated provider, whose rates the PSC approves directly.

The Georgia Public Service Commission does not rank or endorse marketers.

Common questions

Will my gas be shut off when I switch?
No. Atlanta Gas Light owns the pipes and the meter and keeps delivering throughout. Nobody visits your house, nothing is disconnected, and there is no gap in service. The only thing that changes is which company bills you.
How long does it take to switch gas marketer in Georgia?
Enroll by the 19th of the month and the new marketer takes over on the first of the next month. Enroll after the 19th and you wait for the month after that. There is no way to make it faster, because the change happens at the monthly meter read.
Does it cost anything to switch?
The new marketer charges nothing to take you on. The cost, if there is one, is owed to the marketer you are leaving: a fixed-rate contract can carry an early termination fee, commonly $100 to $200 in Georgia. Month-to-month variable plans normally have none.
Do I need my Atlanta Gas Light account number?
Yes. The new marketer needs the AGL account number for the meter, which appears on your current gas bill. It identifies the meter, not the marketer, so it stays the same no matter how many times you switch.
Can I switch if I rent?
Yes, if the gas account is in your name. If it is in the landlord's name, they choose the marketer and you cannot change it.
