Ameresco has been selected for the RE:FIT 5 framework, reinforcing its role as a leading energy solutions provider supporting UK public sector organisations to decarbonise their estates. This procurement framework, launched by the Mayor of London in April 2026, enables councils, education and healthcare institutions, and other public organisations to accelerate progress toward net zero.
