Eversource customer care number: how to reach the right team quickly

Eversource Energy is New England’s largest energy delivery company, serving approximately 4.4 million electric and natural gas customers across Connecticut (CT), Massachusetts (MA), and New Hampshire (NH). Because the company operates in multiple states and lines of business, the best customer care number depends on where your service is located and whether you need help with electric service, gas safety, billing, or an outage.

If you are unsure which number to call, start at the official contact hub at https://www.eversource.com and choose your state (CT, MA, or NH). Numbers and choices on the phone menu can change during major storms or emergencies, and the website always lists the current lines, hours, and outage resources. For life-threatening emergencies, call 911 first, then contact the appropriate Eversource emergency line.

The right Eversource customer care number by state

The most direct route to a live agent is to call the state-specific number for your service address. The electric lines below are staffed 24/7 for outages and emergencies and can also route you for billing and service questions. If you have Eversource natural gas service, use the gas emergency number shown for your state when you smell gas or suspect a leak—those lines are also monitored 24/7.

Have your Eversource account number (from your bill or online account), service address, and callback phone ready. If you do not have an account yet (for move-in/start service), the electric numbers below can set up service after verifying identity and tenancy/ownership details.

• Connecticut (CT) — Electric customer care and outages: 800-286-2000 (24/7). Gas emergency (CT only): 877-944-5325 (24/7). For non-emergency gas billing/service in CT, call the electric line and follow prompts for natural gas.
• Massachusetts (MA) — Electric customer care and outages (Eastern MA): 800-592-2000 (24/7). Electric customer care and outages (Western MA): 877-659-6326 (24/7). For Eversource Gas in MA, use the emergency number printed on your gas bill or meter tag for leaks; you can also call the electric line for your region and select the gas/safety prompt to be transferred immediately.
• New Hampshire (NH) — Electric customer care and outages: 800-662-7764 (24/7). Eversource does not provide natural gas distribution in NH; for gas emergencies in NH, contact your local gas utility directly.

Hours, live-agent availability, and call-backs

Outage and safety lines are staffed 24 hours a day, every day of the year. Billing, payment arrangements, new-service requests, and energy efficiency program teams generally operate during standard business hours on weekdays, with extended hours during high-demand seasons and storms. When call volumes are high, Eversource often enables a call-back option in queue so you do not lose your place; listen for the prompt near the start of the call.

For fastest resolution, call outside peak times (typically late mornings early in the week). You can also start many requests in your online account at https://www.eversource.com and, if needed, continue with a call—agents can see your submitted forms, outage reports, photos, and meter readings, which shortens handle time.

Faster options than calling

Outage reporting and status: Use the state outage map at https://www.eversource.com under “Outages” to report an outage, check estimated restoration times (ETRs), and see the count of affected customers by town and circuit. During major events, ETRs are updated as crews assess damage; the map shows timestamped updates and crew assignments.

Billing, payments, and start/stop service: You can pay online, set Auto Pay, enroll in Budget Billing (levelized payments based on prior usage), and request start/stop/transfer service without calling. Log in at https://www.eversource.com, choose your state, and select “My Account.” If you are moving, submit requests at least 2–5 business days in advance to ensure meter reads and service coordination.

What to have ready when you call

Having the right details at your fingertips speeds up verification and reduces repeat calls. For identity protection, Eversource will not discuss account specifics until you are verified, so it helps to gather the items below before dialing.

For outages and safety issues, include specific location details (cross-streets, visible damage, and whether neighbors are also out). For billing or service changes, be prepared to confirm tenancy and provide contact details for landlords or property managers if applicable.

• Account information: Eversource account number (from your bill or online), service address, and name exactly as it appears on the account.
• Verification: A callback phone number on file, the last 4 digits of SSN or taxpayer ID (for residential), or your business FEIN (for commercial).
• Outage details: Time power was lost, whether you heard a bang/saw a flash, any wires down or limb-on-line, and if medical equipment is in use at the location.
• Move-in/move-out: Lease or closing date, property access instructions, landlord/agent contact, and a forwarding mailing address for final bills or security deposits.
• Payment help: Your monthly budget, proof of income (if applying for assistance), and prior payment history to set up a plan that fits.

Programs and assistance you can request by phone

Payment arrangements: If you have a past-due balance, call before your due date to set a formal payment plan. In many cases, flexible plans are available that spread repayment over several months and protect you from late fees once you are on the arrangement. Ask about Budget Billing to smooth seasonal spikes.

Low-income and medical protections: Depending on your state, you may qualify for arrearage forgiveness or discounts (for example, New Start and Matching Payment programs in CT, low-income discounts in MA). If anyone in your home relies on life-sustaining medical equipment, request a Medical Protection designation—your clinician will need to submit a form, and Eversource will code your account for priority communication during outages.

Safety first: when not to call customer care

If you smell gas, hear a hissing sound near a gas line, or suspect a leak, leave the area immediately. Do not operate electrical switches or phones inside the building. From a safe location, call the gas emergency line for your state (CT: 877-944-5325) or 911. Gas emergency dispatchers are separate from billing agents and will send responders 24/7.

For downed wires or a pole/transformer fire, stay at least 30 feet away, keep others back, and call the electric emergency line for your state (see numbers above) or 911. Treat all lines as energized. Eversource coordinates with fire and police to secure the scene and will update ETRs as crews make repairs.

Escalation paths and regulatory help

If you have tried the appropriate Eversource customer care number and your issue remains unresolved after a reasonable time, ask to open or escalate a case and request a case or incident number. Keep notes with dates, names, and summaries of conversations; these details help the next agent or supervisor quickly see what has already been done.

For persistent issues, contact your state’s utility regulator for consumer assistance. You can file a complaint online with your state: CT—Public Utilities Regulatory Authority (ct.gov/pura); MA—Department of Public Utilities (mass.gov/orgs/department-of-public-utilities); NH—Public Utilities Commission (puc.nh.gov). Provide your Eversource case number and documentation to speed review.

Quick reference and verification

Save the appropriate Eversource customer care number in your phone under “Eversource – CT/MA/NH” so you can reach it during an outage. If you split time between locations, label each entry with the state and region (e.g., “Eversource MA East 800-592-2000”). For the most current numbers, hours, and storm updates, always verify at https://www.eversource.com before you call.
