National Grid provides both gas and electric service, but which one you get depends on where you live

National Grid is a utility company that operates in the northeastern United States and the United Kingdom. In the U.S., they deliver both natural gas and electricity to homes and businesses, but not everywhere they operate offers both services. Some regions receive only gas, some only electricity, and some receive both. Your address determines which services are available to you.

The company does not generate the power or gas itself in most cases — they own and maintain the pipes and wires that deliver these services to your home. A separate company may generate the electricity or produce the gas, but National Grid handles the delivery infrastructure.

Key Takeaways

  • National Grid delivers both natural gas and electricity in parts of the Northeast, but availability depends entirely on your location.
  • The company maintains the physical infrastructure — pipes for gas, wires for electricity — but often does not generate the energy itself.
  • You can check what National Grid services are available at your address through their website or by calling their customer service line.
  • Your bill may show separate charges for gas and electricity if both are available, or you may receive service from different providers depending on your area.

Where National Grid operates in the United States

National Grid serves customers across New York, Massachusetts, and Rhode Island for both gas and electricity. In some of these areas, they deliver only one service. For example, parts of upstate New York may have National Grid electricity but receive gas from a different provider, or vice versa.

The company also operates in the United Kingdom, where they are a major energy distributor, but this article focuses on U.S. service areas. If you live outside the Northeast, National Grid almost certainly does not serve your address.

How to find out which services National Grid provides at your address

The fastest way to check is to visit the National Grid website and enter your address in their service area tool. This will show you whether electricity, gas, or both are available from them at your location. The tool takes less than a minute and gives you a definitive answer.

You can also call National Grid customer service directly. Have your street address and zip code ready. They will tell you which services they provide and can answer questions about your current bill or service options. The phone number appears on any bill you may already receive from them, or on their website.

What the difference means for your bill and service

If National Grid provides both services at your address, you will likely receive one bill with separate line items for gas and electricity. Each service has its own meter — one for gas, one for electricity — and National Grid reads both. The charges reflect the amount of gas and electricity you used, plus delivery fees and taxes.

If only one service is available from National Grid, your other utility may come from a different company. For example, you might receive electricity from National Grid and gas from a local municipal gas company. In that case, you would receive two separate bills from two separate providers.

The difference between generation and delivery

National Grid owns the wires and pipes that bring energy to your home, but they do not always own the power plants or gas fields that produce the energy. In some regions, you can choose your energy supplier — the company that generates or sources the electricity or gas — while National Grid remains your delivery company. In other regions, National Grid handles both.

This matters because your bill may show charges from both a supplier and a delivery company. The delivery charge pays for maintaining the infrastructure that reaches your home. The supply charge pays for the actual gas or electricity you used. Understanding this split helps you read your bill and know who to contact if you have questions about rates or service.

What to do if you are not sure whether National Grid serves you

Start with the service area tool on their website — it is the most reliable method. If you cannot access the internet, call their customer service line. Have your full address ready, including the street number, street name, city, and zip code. They will confirm within seconds whether they serve your location.

If National Grid does not serve your address, they can often tell you which utility does. This is helpful if you need to contact a different company about your gas or electric service. Keep the name and phone number of your actual provider so you know who to call with questions or to report an outage.

Frequently Asked Questions

Can I choose a different gas or electric supplier if National Grid delivers to my address?

It depends on your state and region. Some areas allow you to choose your supplier while National Grid remains your delivery company. Other areas do not offer this choice. Check your bill or contact National Grid to learn whether supplier choice is available where you live.

Why does my bill show charges from both National Grid and another company?

You are likely seeing charges from both a delivery company and a supplier. National Grid (or another company) delivers the energy, and a separate supplier provides it. Both charges appear on the same bill. This is normal and does not mean you have two separate accounts.

What should I do if my gas or electric service stops working?

Contact the delivery company — National Grid if they serve your address. They maintain the infrastructure and can dispatch someone to fix the problem. Have your account number or address ready. If you are unsure whether National Grid delivers to you, call their number first and they will direct you to the right company if needed.

Does National Grid charge different rates in different parts of their service area?

Yes. Rates vary by region and can change based on local infrastructure costs, demand, and state regulations. Your specific rate depends on which part of New York, Massachusetts, or Rhode Island you live in. Check your bill or the National Grid website to see the rates for your area.
