CNG offers several programs to assist customers financially with their bill. In addition, there are a variety of state programs that may be able to provide you with financial assistance with your utility bill.
Connecticut Natural Gas Assistance Programs
- Winter Protection Program - CNG offers winter protection to all our customers that qualify. If you meet eligibility requirements, we will not turn off your electricity between November 1 and May 1. The Winter Protection Plan must be renewed annually, beginning in October. To prevent your service from being shut-off after May 1, contact CNG to setup a payment arrangement.
- Matching Payment Plan - For families that qualify, CNG will match every dollar paid by you or on your behalf (up to a zero balance) if you successfully complete the plan. So, you pay a portion, energy assistance pays a portion and we pay a portion. Bottom line: you may have to pay for only about one-third of your gas heating expense if you qualify. Eligibility is based on income and assets. Call us at 860.727.3034 or InfoLine at 2-1-1 to learn more.
- Payment Arrangements - Special payment arrangements can be set up for you through our customer information department. Call us at 860.727.3034 to discuss your needs confidentially.
State Assistance Programs
- Info Line - 2-1-1 InfoLine is a single source for information about community services, referrals to human services, and crisis intervention. It is accessed toll-free from anywhere in Connecticut by simply dialing 2-1-1. It operates 24 hours a day, 365 days a year. TDD access and multilingual caseworkers are available.
- Operation Fuel - This is a statewide program that brings emergency energy assistance to families facing an economic crisis during the entire year. You can add a dollar or more to your monthly bill and CNG will match your contribution 50%.
- Connecticut Energy Assistance Program (CEAP) - The federally-funded Connecticut Energy Assistance Program (CEAP) is designed to help low-income households pay their winter heating bills. CEAP is not designed to pay total heating costs. Households must plan to pay a part of the bill themselves. CEAP applications are handled by the local Community Action Agency (CAA).

Use your senses to detect gas leaks. A natural gas leak is usually recognized by smell, sight, or sound. Remember, if you smell natural gas, get up, get out and call us immediately from a neighbor's phone.
Natural gas is colorless and odorless. For your safety, a distinctive, pungent odor, similar to rotten eggs, is added so that you'll recognize it quickly. Not all transmission lines are odorized.
You may see a white cloud, mist, fog, bubbles in standing water or blowing dust. You may also see vegetation that appears to be dead or dying for no apparent reason.
You may hear an unusual noise like roaring, hissing, or whistling.
If you suspect a gas leak get up, go outside and call CNG from a neighbor's phone toll free at 866.924.5325 or call 911 for your local fire department. CNG will respond quickly to ensure that you and your family are safe.
- Do not operate electrical switches or appliances. These items may produce a spark that might ignite the gas and cause an explosion.
- Do not use a telephone.
- Do not light a match or smoke and extinguish any open flames.
- Do not assume someone else will report the condition.
- Do not open windows and doors to ventilate the area.
- Provide CNG with the exact location, including cross streets.
Let us know if sewer construction or digging activities are going on in the area.
Yes. Most natural gas equipment vent from the roof but some vent from other parts of your home, such as the sidewall. Periodically check outside your home to make sure your furnace, water heater, dryer, or fireplace vents are not blocked by snow and/or ice.
Pressure regulators and relief valves have a pressure relief vent that must be capable of venting gas safely to open air. When a pressure regulator is located inside a building the vent must be piped to an area outside of the building so if it operates it will vent safely to free air.
Yes. Snow and ice can block gas services valves and make it difficult for first responders to turn off the gas to a building in the event of a fire or gas leak. Pressure regulators and relief vents can also become blocked. If this occurs, an over-pressurization or under-pressurization could result in a hazardous condition for customers.
At CNG, we want to make the process of starting or stopping service simple and convenient for our customers.
Please call CNG's Customer Care Center and someone will assist you Monday through Friday, 8:00 a.m. to 6:00 p.m.

Convert to gas
Even with recent oil price fluctuations, natural gas continues to be the more affordable energy option. Most natural gas used in North America is domestically produced – so it’s not subject to the same swings and spikes seen in world oil markets – making it the more affordable and stable choice for heating your home. Use our easy Energy Calculator to see just how much you could save by making the switch.
Yes. With natural gas you benefit from both price and efficiency. Whether for the home or business, natural gas is the most efficient choice. So look beyond which energy source costs more (or less) from year to year and do consider system efficiency.
Natural gas furnaces & boilers are up to 96% efficient. What's more, natural gas boilers maintain high efficiency ratings and offer higher combustion efficiency over time without loss of efficiency due to soot build up inside the boiler as a result of burning oil.
The Home Energy Solutions program is a great place to start finding ways to save energy at home. It's a home energy assessment performed by a utility-authorized contractor who makes on-the-spot improvements, including caulking and sealing of critical air leaks and provides exclusive money-saving rebates on appliances, heating and cooling systems and more. A modest fee is collected at the time of service and your income may be eligible for a free energy assessment. Call 877.WISE.USE (877.947.3873) to speak with an energy professional during business hours.
There is no weather normalization fee as part of the rate structure for gas companies in Connecticut. Therefore, if the weather is warmer, and you use less energy to heat your home, you save money. It's as simple as that!
Unlike the electric grid which consists of wires and poles, natural gas is delivered via underground pipeline that generally is not affected by storms such as Sandy. However, most heating systems require electricity to operate fans, pumps and the distribution of heat so you may want to consider a natural gas generator.
Further, there is no need for delivery trucks to get through blocked roads or for you to maintain oil tanks in your home.
Because it burns cleaner and is more efficient, natural gas is better for the environment, and natural gas efficiency programs can save energy and reduce carbon emissions even more.
With natural gas, there is no need for a storage tank. This allows customers to free-up space in their basements, and for tanks that are underground, costly liabilities can be avoided from tank removal. Most natural gas is produced in North America so there is less dependence on foreign oil.
