National Grid

Leaving natural gas service connected poses a hazard that could result in fire, explosion, and loss of life and property. It can also cause undetected gas leaks that later may lead to damage and threaten lives.

Arrange to disconnect service before you begin demolition or major renovation work on or around any property

Contact National Grid’s Customer Service Center.

Call well in advance of starting work to speak with a representative about the scope of your project and to make arrangements to properly disconnect natural gas service and remove the meter:

•	Massachusetts: 1‑800‑233‑5325

•	Long Island and the Rockaways: 1‑800‑930‑5003
•	Metro New York: 1‑718‑643‑4050
•	Upstate New York: 1‑800‑642‑4272

Be clear about the work that is being done.

Do NOT request a simple shut‑off of the gas when major work is planned. Shut‑off is for transition to new resident/owner when no construction or renovation is involved. It is not safe to leave utilities connected while major construction is underway.

Submit your request.

You must submit a Gas Service Line Alteration and Verification Request to National Grid to obtain a Service Line Disconnect Letter before starting work.

DO NOT begin work until you receive a Service Line Disconnect Letter.

•	Disconnect Letter provided upon request in Upstate New York.
•	You may make arrangements for the natural gas disconnect on the property owner’s behalf. In Massachusetts and Downstate New York, the owner must provide an affidavit authorizing this work.

•	Each project is unique and fees may apply. Please contact your Customer Service Center for more information.
