South West London Environment Network (SWLEN) builds active and engaged communities who protect and enhance our local environment. We work in the London Boroughs of Richmond upon Thames, Ealing, Hounslow and Kingston upon Thames. Our work focuses on preserving and protecting green spaces and biodiversity through community and voluntary groups involvement, promoting sustainability and community development.

SWLEN also chairs and acts as the secretariat of the Richmond Biodiversity Partnership.

Vision & Values

SWLEN exists to build active and engaged communities who protect and enhance our local environment. Our core values are:

  • Local empowerment – we passionately believe the best way to protect and enhance the environment is through empowering local people to take an interest, become involved and to take action themselves.
  • Collaboration and partnership – we know that by working together we achieve more, and in sharing best practices we are strong together. This approach brings wider benefits to the community, charitable organisations and local authorities.
  • Environmental protection and enhancement– we exist to ensure South West London maintains a thriving and sustainable environment.

History & Governance

SWLEN is a registered charity (no. 1140872) and registered in England and Wales as a company limited by guarantee (no. 7469024) established in 2011. SWLEN’s history dates to the founding of Richmond’s LA21 Group in 1994 in response to the UN Rio Earth Summit of 1992, agenda item 21 was the adoption of sustainable development principles of each signatory country, with each local authority (hence LA21) in these countries working towards adopting and delivering these goals.

Richmond’s LA21 group collaborated with SWLEN’s predecessor Richmond Environment Network (REN) from its founding in August 2004 sharing a member of staff.  REN was formed by three local environmental organisations: the Environment Trust, Thames Landscape Strategy and Richmond office of The Conservations Volunteers to be the umbrella body and ‘network’ for the local environmental voluntary sector. After working in collaboration for three years Richmond’s LA 21 Group and REN merged in 2007. In 2008 the charity Richmond Environmental Information Centre (charity no. 1053104) closed down and transferred its assets to REN. In 2015 SWLEN established a wholly owned social enterprise (SWLEN – SE)

SWLEN is governed by a board of trustees, with operational management delegated to the executive, led by Chief Executive Colin Cooper. There are a number of committees and subgroups reporting to the board.
