How to measure the impact that charities and social enterprises have on their communities is a hotly debated topic. CAN Mezzanine, a UK-based social enterprise that provides office space for third sector organizations, has been using SROI (social return on investment) tools to measure the social value created for the charities and social enterprises that rent its central London office buildings, particularly the benefits of collaboration.

CAN is a charity that helps social enterprises and charities to scale up their business and maximize their social impact. Its own social enterprise, CAN Mezzanine, provides high-quality, flexible office space in three central London office buildings for around 122 charities and social enterprises.
