National Grid offers a number of programs to encourage energy efficiency amongst its residential customers.

National Grid’s High Efficiency Heating Rebates are offered to any residential gas heating customer in Massachusetts, New Hampshire, Rhode Island and Metro New York. Eligible technologies include boilers, furnaces, water heaters, ventilators, and equipment controls. Rebates of up to $2,000 are available, depending on equipment type. All equipment must meet certain energy standards provided on the website. Applications are to be completed and sent in after equipment installation. The application form is available on the program's website.

The utility has a separate rebate program specific to solar thermal water heating. Incentives cover 15% of project costs, up to $1,500. Applications for this rebate can be found off the program website above.

National Grid Residential Weatherization Program is for heating customers in New England. The program provides a rebate covering 75% of the cost, up to $2,000, for various weatherization measures, including: attic, wall, basement, crawl space, rim joist, and heating system duct insulation; attic ventilation; and air infiltration and ductwork leakage testing and sealing.
