Before you go
What a local office actually handles
Walk-in offices are made for face-to-face billing and account work. Everything urgent is handled by the central phone lines, faster.
What you can do at the counter
- ✓ Pay a bill in cash or with a check, especially useful if you do not have a bank account or want a same-day stamped receipt.
- ✓ Set up a payment plan or budget billing arrangement if you have fallen behind.
- ✓ Open or close an account with photo ID, if you have not already done it by phone or online.
- ✓ Resolve a disconnection notice face to face, before the shut-off date.
- ✓ Apply for a low-income discount (Discount Rate) and submit supporting documents.
What the office is not for
- ✗ Reporting a power outage. Call 1-800-465-1212, 24/7. Office staff cannot dispatch crews.
- ✗ Reporting a gas leak. Leave the building first, then call 1-800-233-5325 from outside.
- ✗ Comparing competitive supplier offers. National Grid is the delivery utility. Supplier shopping happens on our supplier directory or on EnergySwitchMA.gov.
- ✗ Scheduling a meter install or move. Field crews are dispatched by phone, not from the counter.
- ✗ Walk-in service outside hours. Most offices keep weekday business hours only. After hours, use the phone lines or the National Grid mobile app.

Insider tip
National Grid is your delivery company, not your supplier
Like Eversource, National Grid owns the wires and pipes that bring electricity and gas to your home. The kilowatt-hours and therms themselves can be bought from National Grid (Basic Service) or from any licensed competitive supplier in MA.
Walking into a National Grid office to ask about cheaper supply will not get you very far, the staff is trained on delivery and billing, not on the competitive market. For supplier shopping, see our MA supplier directory or the state-run EnergySwitchMA portal.
Quick answers
Before you make the trip, the most common questions about National Grid MA.
Usually no. Almost everything (start service, stop service, set up auto-pay, request a payment plan, change your mailing address) can be done by phone at 1-800-322-3223, in the National Grid mobile app, or on nationalgridus.com. Walk-in offices are most useful for cash payments, in-person help with a disconnection notice, or low-income discount paperwork.
Most National Grid MA offices keep weekday business hours, typically Monday to Friday from 8 a.m. or 9 a.m. to around 4 p.m. or 5 p.m. ET, closed on weekends and federal holidays. Hours can vary by location, so check the office page before driving over.
No. Call the 24/7 outage line at 1-800-465-1212 or report online. The office staff cannot dispatch crews and the office may itself be in the outage.
Leave the building immediately. Do not flip light switches, do not start your car nearby, do not call from inside. Once outside, call the 24/7 gas emergency line at 1-800-233-5325. National Grid will dispatch a technician at no charge.
Yes. Massachusetts retail choice applies in the National Grid footprint. You can stay on National Grid Basic Service (default), pick a competitive supplier directly, or enroll in your town's municipal aggregation if one exists. The delivery half of your bill stays with National Grid no matter what.
Call your competitive supplier first to cancel (watch for any termination fee on a fixed-rate contract), then call National Grid at 1-800-322-3223 to confirm the return to Basic Service. There is no fee to switch back, and it takes one to two billing cycles.
