Before you go
What an NH utility office actually handles
Walk-in offices are built 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, 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 the Electric Assistance Program (EAP) and submit supporting documents at a Liberty or Unitil walk-in office.
What the office is not for
- ✗ Reporting a power outage. Call your utility's 24/7 outage line. Office staff cannot dispatch line crews.
- ✗ Reporting a gas leak. Leave the building first, then call Liberty NH gas at 1-855-849-9455 or Unitil gas at 1-866-900-4115 from outside.
- ✗ Comparing competitive supplier offers. The utility is the delivery side of your bill. Supplier shopping happens via our NH supplier directory or PUC.NH.gov/EnergyChoice.
- ✗ Scheduling a meter install or move. Field crews are dispatched by phone, not from the counter.
- ✗ Walk-in service outside business hours. Both Liberty Tilton and Unitil Kensington keep weekday-only hours. After hours, use the phone lines or your utility's mobile app.
Your NH utility is your delivery company, not your supplier
Since 2003, New Hampshire households can choose where the kilowatt-hours come from. The utility still owns the wires, the meter and the bill.
NH residential meters
Three IOUs (Eversource, Liberty, Unitil) plus ~13 municipal departments.
Year retail choice opened
Under the 1996 Restructuring Act, residential supplier shopping became available in 2003.
Default rate resets
Eversource Energy Service and Liberty / Unitil Default Service prices reset every 6 months.
Insider tip
Default Service is not your only option
All three NH investor-owned utilities (Eversource, Liberty, Unitil) buy power in a competitive auction and pass it through as "Default" or "Energy" Service. The rate resets every February 1 and August 1. Walking into a Liberty or Unitil office to ask about cheaper supply will not get you far, the counter staff is trained on delivery and billing, not on the competitive market.
For supplier shopping, see our NH supplier directory or the NH Public Utilities Commission's energy-choice portal. Towns inside a municipal-electric footprint (Ashland, Wolfeboro, Woodsville, and the other ~10 NH munis) do not have supplier choice, the town buys and sets the rate directly.
Quick answers
Before you make the trip, the most common questions about NH utility offices.
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 or online. Eversource NH (1-800-662-7764) has no walk-in counter at all. Liberty (Tilton) and Unitil (Kensington) keep weekday office hours, most useful for cash payments, in-person help with a disconnection notice, or Electric Assistance Program paperwork.
Liberty Utilities Tilton: Monday to Friday, 9 a.m. to 5 p.m. Unitil Kensington: Monday to Friday, 8 a.m. to 5 p.m. Both close weekends and federal holidays. Hours can shift, so check before driving over.
No. Call the 24/7 outage line for your utility. Eversource NH: 1-800-662-7764. Liberty Utilities: 1-855-849-9455. Unitil: 1-888-901-5711. The office may itself be in the outage, and counter staff cannot dispatch crews.
Leave the building immediately. Do not flip light switches, do not start your car nearby, do not call from inside. Once outside, call your gas utility. Liberty NH gas: 1-855-849-9455. Unitil gas: 1-866-900-4115. The technician dispatch is free at the meter.
Yes, in Eversource, Liberty and Unitil footprints (the three investor-owned utilities). Households can stay on the utility's Default Service (default), pick a competitive supplier directly, or enroll in a Community Power program if their town offers one. The delivery half of your bill stays with the utility no matter what. In NH municipal-electric towns (Ashland, Wolfeboro, Woodsville, etc.), retail choice does not apply.
Call your competitive supplier first to cancel (watch for any termination fee on a fixed-rate contract), then call your utility to confirm the return to Default Service. There is no fee to switch back to the utility, and it usually takes one to two billing cycles.
