Unitil offers rebates for multifamily customers as well as small and large businesses. Eligible multifamily buildings have more than four units, a master-metered account, and use gas heat and/or gas hot water. Customers who have a commercial or industrial building that has an annual gas usage of 40,000 therms or less qualify for the small/medium business customers program. All gas customers whose annual use exceeds 40,000 therms, plus all municipal buildings, hospitals, and universities, qualify for the large business program.

To access these incentives, customers start with a free (or reduced rate) energy audit. Eligible energy efficient upgrades are similar for all three programs with slight variations; customers should check Unitil's Commercial and Industrial Energy Efficiency web site for details.
