Unitil offers its New Hampshire residential gas customers a number of programs to encourage more energy efficient homes. The Home Performance with Energy Star Program is available to customers with higher than average energy bills. The program includes a home energy audit which identifies potential areas for energy efficiency improvements.  Qualifying improvements can result in a 50% utility rebate for the customer, up to $4,000.  Common energy savings improvements utilized by the program include:
  • Sealing air leaks and adding insulation
  • Improving heating and cooling systems
  • Sealing ductwork
  • Upgrading lighting, appliances, and water heating equipment
  • Installing renewable energy systems

Until also offers rebates for residential new construction through the Natural Gas Energy Star Homes/Residential New Construction Program. To receive rebates, new homes must meet certain energy efficiency criteria.

In addition to these two comprehensive home efficiency programs, Unitil offers its customers a variety of individual rebates for home heating and water heater improvements. Unitil also offers a special Home Energy Assistance Program for income-qualified households that provides up to $8,000 in energy efficiency and weatherization upgrades.
