Calling this National Grid Customer Number

2025-05-15T00:00:00.000Z

I'm planning a move and I need to take care of a few tasks before the move actually happens One of the tasks on my to-do list is to transfer my utility services. Working my way through the list, I could see that I had to call the National Grid to get my electrical service moved to my new home. I had been putting this task off because I hate waiting on hold, and I figure with the early summer storms we've been having, there might be a wait. Plus, the National Grid also deals with natural gas so between gas and electrical services, they may have a lot of customers that need service at any one time. 

Luckily, it didn't take that long at all. When I called, an automated agent said, "Thank you for calling National Grid, for English press 1. For espanol, press 2. If you are calling to report a damaged gas line or gas odor, press 1. To report a power outage, downed wire, or street light, otherwise, please press 3 to continue."

I pressed 3 since I didn't have an emergency to report, and it said, "Please say or enter the service zipcode for your service address. In a few words, briefly tell me the reason for your call today?" I responded that I wanted to "transfer my service" and it asked me back if I wanted to stop one service and start another. Once I confirmed that I did, it asked me, "How would you like to look up your account? By phone number, social security number, or account number."

I chose phone number, and once I entered my number it transferred me to a representative. I had to sit on a hold line for about two minutes and then I was able to talk to someone and resolved the entire issue in just under five minutes.
