Is Swansea in Mass Save?

Swansea is not on the state's list of municipal light plants. Mass Save is not statewide: 41 light plants serve all or part of 50 municipalities, and homes on their electric service are outside its electric program (Mass Save in municipal light plant towns).

Window rebates and financing in Swansea

Mass Save pays $75 per window in 2026, and only when ENERGY STAR Most Efficient windows replace single-pane windows after you complete the weatherization recommendations from a Home Energy Assessment.

Replacing double-pane windows earns no rebate. The 0% HEAT Loan can finance ENERGY STAR replacement windows, but only alongside completed weatherization recommendations.

Do you need a permit for replacement windows or doors in Swansea?

Plan on one. Window and door replacement is not on the Massachusetts building code's list of permit-exempt work, and the Swansea Building Department decides whether a same-size swap counts as an ordinary repair. 71% of Swansea's homes were built before 1980 (Census ACS 2018-2022), and work that disturbs paint in a home built before 1978 has to follow the lead-safe renovation rules.
