About Unitil in New Hampshire

Unitil Corporation (NYSE: UTL) is a publicly traded utility holding company headquartered in Hampton, NH. In New Hampshire, Unitil operates two regulated businesses: Unitil Energy Systems (electric) and Northern Utilities (natural gas). Together they cover the Capital area around Concord (~78,000 electric customers) and the Seacoast around Exeter and Hampton (~33,000 gas customers, plus an electric subset).

Kensington (ZIP 03833) sits in Unitil's Seacoast electric territory between Exeter and the Massachusetts border. The town does not have a dedicated walk-in office; service requests, bills, gas-leak emergencies and outage reports all route through Unitil's 24/7 Seacoast call center at 1-800-582-7276. For in-person business, the closest staffed Unitil location is the Hampton headquarters at 6 Liberty Lane West (ZIP 03842).

As an investor-owned utility, Unitil earns a regulated return on its rate base set by the NH Public Utilities Commission. Like every NH wires utility, Unitil is a delivery company, the supply on your bill comes from default service auctions, Community Power, or a competitive supplier you choose.

Frequently asked questions

Is there an actual Unitil office in Kensington?
No. Kensington is part of Unitil's Seacoast electric territory but there is no staffed customer counter in town. For in-person business, the closest Unitil location is the company headquarters at 6 Liberty Lane West, Hampton, NH 03842. All other transactions route through the toll-free line or Unitil Connect.
Can I shop for a cheaper supplier on Unitil's wires?
Yes. New Hampshire has had retail electric choice since 1996. Unitil handles delivery either way; you can stay on Unitil's default service, join a municipal Community Power program if your town runs one, or pick a licensed competitive supplier.
What do I do if I smell gas?
Leave the building immediately. Do not flip switches, light matches or use a phone inside. Once safely outside, call the Northern Utilities gas-emergency line at 1-866-533-3661 or 911 if there is fire or injury.
Who do I call for a downed power line?
Call Unitil 24/7 at 1-800-582-7276. If a wire is on the ground or anyone is hurt, dial 911 first. Never approach a downed line; assume it is energized.
Are Unitil customer service lines staffed 24/7?
Yes. Both the Seacoast line (1-800-582-7276) and the Capital area line (1-800-852-3339) are staffed 24 hours a day, every day, including holidays. Self-service IVR is always available.
Is help available if I cannot pay my bill?
Yes. NH residents may qualify for LIHEAP fuel assistance, the Electric Assistance Program (8 to 76% bill discount) and the Unitil Customer Assistance Fund. Apply through your local Community Action Agency before a shut-off notice arrives.
