Unitil customer service phone number — authoritative guide

Executive summary and primary contacts

Unitil Corporation is a regional utility serving electric and natural gas customers in New Hampshire, Maine and Massachusetts. For immediate, authoritative contact information start at Unitil’s official site: https://www.unitil.com. The corporate headquarters is listed as 6 Liberty Lane West, Hampton, NH 03842; the corporate switchboard is commonly reached at (603) 773-6500 (verify the number printed on your bill or at unitil.com/contact-us before relying on it for time-sensitive matters).

Customer-facing telephone numbers are organized by function (billing, new service, outages, gas leaks, investor relations). Numbers that apply to your account also appear on every bill and on the Unitil account portal. Because Unitil operates both regulated delivery and customer service centers, call routing differs by state and service type — confirm the specific line for your town or meter on the contact page (https://www.unitil.com/contact-us) or the printed section of your last bill.

How to locate the correct Unitil phone number quickly

The fastest and most reliable method is to consult the bill: the customer service and emergency numbers for your account are printed at the top and in a dedicated “Contact Us” box. Unitil prints distinct numbers for general account questions, payment arrangements, and emergencies (outages or gas leaks). If you have electronic billing, the Unitil online portal displays the same telephone numbers under “Help & Contact.”

If you cannot access a bill, go to https://www.unitil.com and use the “Contact Us” link. That page lists phone numbers by state and by issue (billing, service start/stop, construction coordination, and emergency response). For time-sensitive emergencies (suspected gas leak or immediate electrical hazard), call local emergency services (911) first and then use the utility’s emergency phone line listed on the website or on the back of your meter.

Common phone lines and when to call them

Unitil structures phone support so callers reach the most appropriate team quickly. Typical categories include: general customer service (account inquiries, meter reads, service changes), billing & payments (past-due notices, payment plans), outages & emergencies (power restoration and gas leaks), and commercial/installation (service extensions, large-meter coordination). Each category will have a dedicated number or press-key option on the main menu.

Because phone menus and hours can change, use the online contact page for the current menu map, and verify emergency availability. Emergency and outage lines are staffed 24/7; routine billing and business lines most commonly operate Monday–Friday (commonly 8:00–5:00 local time), but check unitil.com for precise hours and holiday closures.

Practical checklist before calling Unitil

• Account information: account number (on the bill), service address, meter number(s). Having the 10–12 digit account or meter ID reduces average handle time to under 6 minutes for routine billing calls.
• Recent bill and usage: current balance, last payment date, and most recent meter read. If disputing charges, prepare copies of bills and dates (Unitil retains detailed usage for the past 24 months in the portal).
• For outages: time outage began, circuit breakers checked, photos if hazards exist. For gas concerns: odor description, location of smell, and whether anyone felt ill; call 911 if immediate danger exists before calling Unitil.

Emergency response, outages and safety procedures

Unitil’s emergency procedures prioritize human safety and rapid restoration. In an electrical outage the utility dispatches crews based on severity (widespread outages, life-support critical facilities, then individual homes). For major outages affected customers can often get status updates via Unitil’s outage center on the website, which provides estimated restoration times, number of customers affected, and restoration progress in near-real-time.

Natural gas emergencies must be treated as immediate threats. If you suspect a gas leak (rotten egg odor, hissing, bubbling in puddles), evacuate the area, do not operate switches or phones inside the building, call 911 from a safe location, then call Unitil’s 24-hour emergency line which is posted on the bill and on https://www.unitil.com. The utility’s field response time standard for confirmed gas leaks is often measured in minutes for immediate hazards and in hours for non-urgent repairs, depending on severity and location.

Alternative contact methods and escalation

If wait times are long, use Unitil’s online account portal to submit secure messages, schedule payment arrangements, view outage maps and start/stop service requests. Many transactional tasks — payments, enrollment in budget billing, and outage reporting — can be completed without a live agent, often reducing resolution time from days to minutes.

For unresolved issues escalate by requesting a supervisor during the call, documenting reference/case numbers, and following up via certified mail to Unitil’s corporate address (6 Liberty Lane West, Hampton, NH 03842) if needed. For regulatory or rate disputes, contact the state public utilities commission in New Hampshire (PUC), Maine (PUC), or Massachusetts (DPU); these agencies can intervene and typically log your complaint within 7–10 business days.
