Stack Your Savings

Massachusetts homeowners can often combine Mass Save rebates, 0% HEAT Loan financing, AND federal tax credits on the same project. For example, a $15,000 heat pump installation could receive a $10,000 Mass Save rebate plus a $2,000 federal tax credit, reducing your actual cost to just $3,000 – and you can finance that with the 0% HEAT Loan.

Finding Contractors in Boston

Massachusetts Contractor Requirements

Massachusetts requires Home Improvement Contractor (HIC) registration for most renovation work. Here’s what you need to know:

HIC Registration

Any contractor doing home improvement work over $1,000 must be registered with the Massachusetts HIC program through the Office of Consumer Affairs and Business Regulation.

Required over $1,000

Electrical Work

Must be performed by a Massachusetts-licensed electrician. Required for all electrical modifications. Verify license through the Division of Professional Licensure.

How to Verify a Massachusetts Contractor

  1. Check HIC Registration: Visit mass.gov/hic to verify Home Improvement Contractor registration
  2. Verify Trade Licenses: Check electrician, plumber, and HVAC licenses through mass.gov/dpl
  3. Request Insurance: Get certificates of liability and workers’ compensation coverage
  4. Check Guaranty Fund: HIC registration includes access to the Home Improvement Contractor Guaranty Fund for consumer protection
  5. Review Reputation: Check Google reviews, BBB rating, and Angi/HomeAdvisor ratings

HIC Registration Protects You

Working with an HIC-registered contractor gives you access to the Massachusetts Home Improvement Contractor Guaranty Fund if work is not completed or is substandard. Unregistered contractors cannot legally perform work over $1,000, and using them leaves you without state protections. Always verify HIC registration before signing any contract.
