Contractor Review Websites

It can be challenging to choose amongst for-profit contractors in the energy efficiency, clean energy, and renewable energy technology space, even when those contractors are deemed ”qualified” or “certified” by local utilities and/or participating government agencies. Here are some third-party review sites that list certified contractors and/or aggregate contractor reviews from both satisfied and dissatisfied customers. Please note that these sites themselves are for-profit review sites that are neither endorsed nor supported by CCE-Suffolk.
