Customer Advisory: UTILITY IMPOSTERS

Washington Gas is advising customers about recent incidents where individuals are posing as utility workers in an effort to access homes or businesses in order to obtain information that can be used in identity theft and fraud.

The company feels it is important to notify customers in an effort to prevent them from becoming potential victims.

Washington Gas offers the following tips to customers:

  • Washington Gas employees on company business are required to carry a photo ID/Company badge.
  •  Washington Gas employees who perform services, including work on natural gas meters or natural gas lines, wear uniforms that carry the Washington Gas logo.
  • Most of the time, a Washington Gas employee responds to a service request. If no one at your address scheduled an appointment, call Washington Gas at 703-750-1000 before allowing anyone inside your home or business.
  • Always ask for identification before allowing anyone inside your home.
  • Never give out any personal, confidential information to unknown or untrusted people or organizations.

If you have any concerns, suspect you have been approached by an imposter, or have information to report regarding this fraud, please contact your local law enforcement office. In addition, you may contact Washington Gas' 24-hour security hotline at 703-750-4370 if you believe your Washington Gas account has been compromised.

Notice to Virginia Customers: CARE Plan 

On March 26, 2010, the Virginia State Corporation Commission issued an Order approving a Conservation and Ratemaking Efficiency (CARE) Plan. The Commission approved a decoupling rate mechanism, the CARE Ratemaking Adjustment (CRA), and six residential energy efficiency programs. The decoupling rate mechanism will work in conjunction with the existing mechanism for a weather normalization adjustment to encourage consumer conservation without penalizing the Company's recovery of its fixed costs. The CRA will appear as a separate line item on residential customer bills beginning in the July 2010 billing cycle. The CARE Cost Adjustment (CCA), which will begin upon implementation of the Company's approved programs, allows for recovery of the residential energy efficiency programs available to residential customers. The CCA will be included as a charge to be added to the residential Distribution Charges.
