Before using Eversource for electric or natural-gas service, it is helpful to know which telephone number applies to your state and service territory. Eversource serves customers in Connecticut, Massachusetts, and New Hampshire, but customer-service, outage, and gas-emergency numbers differ by location.

Eversource provides electric and natural-gas service in Connecticut and Massachusetts and electric service in New Hampshire. Customers should use the telephone number shown on their bill or select their town on Eversource’s website when they are unsure which service territory applies.

How to Contact Eversource Customer Service

Eversource residential customers can use the following state-specific telephone numbers:

Eversource’s residential telephone representatives provide service in English and Spanish. The company does not publish one general customer-service email address for every state and service type. Customers can manage many requests through their online account or use the state-specific telephone number shown on their bill.

The corporate-office number should not be used instead of the appropriate residential customer-service, outage, or gas-emergency number.

Eversource Power Outage Phone Numbers

Customers can report or check a power outage online or use the telephone number for their service territory:

Outage-reporting systems are available outside normal billing-support hours. During a major storm, recorded information, online tools, and text alerts may provide faster updates than waiting for a representative.

When reporting an outage, provide:

  • The service address
  • The telephone number associated with the account
  • Whether neighboring properties are also without power
  • Information about downed wires, damaged poles, trees, smoke, or fire
  • Any special safety conditions at the property

Never approach a fallen power line or anything touching it. Keep people and animals away and report the hazard to Eversource and emergency services.

An estimated restoration time can change as crews inspect damage, identify additional problems, and complete repairs. A posted estimate is not a guarantee that service will be restored at that exact time.

Medical Equipment During an Outage

Customers who rely on electrically powered medical equipment should maintain an emergency plan that does not depend entirely on utility restoration estimates.

During an urgent medical situation, use emergency services rather than waiting for routine utility support. Customers may also need to relocate to a hospital, emergency shelter, cooling center, warming center, or another safe location during an extended outage.

Registering a medical condition with a utility does not guarantee uninterrupted electric service or priority restoration to an individual property.

Eversource Natural-Gas Emergency Numbers

Natural-gas emergency numbers differ from ordinary billing and account-support numbers.

If you smell gas, hear escaping gas, see a damaged gas line, or suspect a leak:

  1. Leave the building or area immediately.
  2. Do not operate lights, appliances, switches, phones, vehicles, or equipment near the suspected leak.
  3. Move to a safe location.
  4. Use 911 to report the emergency.
  5. Report the suspected leak to Eversource using the appropriate gas-emergency number.

Do not return to the property until emergency personnel or the utility says that it is safe.

New Hampshire customers generally receive electric service rather than natural-gas service from Eversource. A New Hampshire gas customer should use the emergency number provided by the company named on the gas bill.

Starting, Stopping, or Transferring Eversource Service

Customers moving into or out of a property can submit a start, stop, or transfer request through an Eversource online account.

Information that may be required includes:

  • The new and previous service addresses
  • The requested service date
  • The customer’s legal name
  • Identity-verification information
  • A telephone number and email address
  • Lease, ownership, or occupancy details when requested
  • Access instructions for an indoor meter

Submit the request before the moving date. Same-day service is not always available, especially when a technician must access the property, restore disconnected equipment, inspect a meter, or complete safety work.

A landlord, tenant, property manager, builder, and previous occupant may have separate responsibilities. Do not assume that another person’s account will automatically transfer into a new customer’s name.

Eversource Billing and Payment Support

Eversource customers can use an online account to view bills, review payment history, monitor energy usage, enroll in available billing programs, and manage account preferences.

Available payment methods may include:

  • Online bank-account payments
  • Automatic payments
  • Telephone payments
  • Text-message payments
  • Payments through the Eversource mobile app
  • Payments by mail
  • Payments through an authorized payment location

Payment options, convenience fees, processing times, and accepted payment methods can vary. Review the instructions displayed in the account or printed on the current bill.

Allow enough processing time before the due date. A bank’s record showing that a payment was initiated does not always mean that the utility has received and posted it.

Understanding Eversource Charges

An electric or gas bill may contain several types of charges, including:

  • Utility delivery charges
  • Energy or supply charges
  • Transmission charges
  • Distribution charges
  • Public-policy or program charges
  • Taxes and government assessments
  • Past-due balances
  • Payment-plan amounts
  • Credits, adjustments, or deposits

Customers using a competitive energy supplier may see the supplier’s name and supply charge on the Eversource bill. Eversource may deliver the energy and issue the bill even though another company sets the generation or supply price.

Questions about the meter, delivery service, outage, or Eversource charge generally belong with Eversource. Questions about a third-party supplier’s contract, variable rate, cancellation fee, or enrollment may also require assistance from that supplier.

Estimated Bills and Meter Readings

A bill may be based on an actual meter reading, customer-submitted reading, or estimate. Estimated bills can later be adjusted when an actual reading becomes available.

Customers questioning a high bill should compare:

  • The number of billing days
  • Current and previous meter readings
  • Whether the reading is actual or estimated
  • Seasonal heating or cooling usage
  • Changes in the supply rate
  • New appliances or equipment
  • Previous unpaid balances
  • One-time corrections or adjustments

Photographing the meter can help document a disputed reading. Do not open, alter, remove, or interfere with utility metering equipment.

Eversource Payment Plans and Financial Assistance

Eversource offers payment arrangements and income-based assistance programs for eligible customers. Available programs and qualification rules differ among Connecticut, Massachusetts, and New Hampshire.

Assistance may include:

  • Extended payment arrangements
  • Budget or level-payment billing
  • State or federal heating assistance
  • Discounted utility rates for qualifying customers
  • Arrearage-management or forgiveness programs
  • Energy-efficiency services
  • Special protections based on household circumstances

Customers having difficulty paying should review the Eversource Payment Assistance page or use the customer-service number for their state.

Do not wait until the scheduled disconnection date. Some programs require an application, income verification, benefit letter, payment agreement, or referral through a community agency.

Eligibility for one assistance program does not automatically qualify a household for every other program.

Disconnection Notices and Billing Rights

Utility billing, collection, and service-termination protections are governed by state rules. Protections may depend on income, season, household members, medical circumstances, payment history, and whether the customer has completed required forms.

Customers who receive a disconnection notice should:

  1. Verify that the notice is genuine.
  2. Review the amount and shutoff date.
  3. Use the official state-specific Eversource number.
  4. Ask about payment arrangements and assistance programs.
  5. Submit any required hardship or medical documentation promptly.
  6. Keep the representative’s name and confirmation number.

Eversource provides state-specific information through its Billing Rights section.

A public comment, online review, or message to an unrelated corporate department does not stop a scheduled disconnection.

Eversource Property Damage Claims

Customers who believe Eversource caused damage to property can review the company’s claims process or use the Claims Department number at 1-844-685-4475.

Potential claims may involve:

  • Damage allegedly caused by utility work
  • Damage involving Eversource equipment
  • Vehicle or property damage near a work site
  • Other losses that the customer believes resulted from Eversource’s actions

Claim types and eligibility vary by state, event, cause, and applicable law. Submitting a claim does not guarantee reimbursement.

Supporting information may include:

  • The Eversource account and service address
  • The date, time, and location of the incident
  • A detailed description of what happened
  • Photographs or video
  • Repair estimates and invoices
  • Receipts showing the amount of the claimed loss
  • Witness information
  • Police, fire, or insurance reports when applicable

Customers should also notify their insurer when required. Filing an Eversource claim and filing an insurance claim are separate processes.

Use the Eversource Claims page for current forms and instructions.

Streetlights, Trees, and Utility Equipment

Eversource provides online service options for certain streetlight, tree, meter, construction, and equipment concerns.

Customers can report matters such as:

  • A streetlight that is out, damaged, or operating during the day
  • A tree or branch interfering with an electric line
  • Damage to a utility pole or meter
  • Construction requiring a new or relocated service
  • A request involving electric or gas equipment

Streetlights may be owned by Eversource, a city, a town, or another organization. Eversource may direct the customer to the responsible municipality when it does not own or maintain the light.

Do not attempt to trim trees near energized power lines. Tree ownership does not make it safe for a property owner or ordinary landscaping contractor to work near electrical equipment.

Avoiding Eversource Payment Scams

Utility scams often involve an unexpected telephone call, message, visitor, or email claiming that service will be disconnected unless immediate payment is made.

Customers receiving a suspicious demand should:

  • End the communication without providing account information.
  • Do not use a telephone number or payment link supplied by the suspected scammer.
  • Use the number printed on the Eversource bill or listed on the official website.
  • Review the account balance through the official Eversource account.
  • Report threats, impersonation, theft, or fraud to the appropriate authorities.

Eversource employees and contractors should be able to provide identification. Customers can verify an unexpected visit by using an official Eversource customer-service number.

How to File an Eversource Customer Service Complaint

Customers with unresolved billing, payment, meter, service, outage, supplier, or property concerns can use the following escalation process:

  1. Use the correct state number. Begin with the customer-service number shown on the bill.
  2. Document the concern. Keep bills, meter photographs, notices, payment confirmations, emails, repair invoices, and outage records.
  3. Request a case number. Record the representative’s name, date, time, and explanation.
  4. Ask for supervisor review. Explain which part of the previous response remains unresolved.
  5. State the requested resolution. Specify whether you want a corrected bill, meter review, payment adjustment, service appointment, claim review, or written explanation.
  6. Escalate to the state regulator when appropriate. Customers should generally give Eversource an opportunity to address the matter before filing a regulatory complaint.

A written complaint should include:

  • The account holder’s name
  • The service address
  • The account number with unnecessary digits concealed when appropriate
  • The state and Eversource service territory
  • The dates and amounts involved
  • Previous case numbers
  • A concise timeline
  • Copies of supporting records
  • The resolution requested

Do not publish an account number, payment information, Social Security number, access code, or home-security information in a public review.

Connecticut Utility Complaints

Connecticut customers with an unresolved regulated-utility complaint can use the Connecticut Public Utilities Regulatory Authority.

Massachusetts Utility Complaints

Massachusetts customers can request assistance from the Department of Public Utilities Consumer Division after attempting to resolve the matter with Eversource.

Customers whose service has already been shut off or is about to be shut off should use the DPU telephone number rather than relying only on an online form.

New Hampshire Utility Complaints

New Hampshire customers can use the Department of Energy Consumer Services Division after giving Eversource an opportunity to address the dispute.

State regulators are not outage-reporting or gas-emergency services. Continue to use Eversource and emergency services for immediate safety concerns.
