Chelmsford Science & Engineering Society (CSES)

CSES was formed in 1920 and is the hub of engineering, technology and science in Essex.


The objectives and purpose of CSES can be summarised in three words: explore · educate · expand

  • Explore: advance the public understanding of science, engineering and technology.
  • Educate: develop tomorrow’s scientists, engineers and technologists through high-quality and inclusive STEM education and by promoting STEM careers.
  • Expand: provide a social and professional network for members.

The society aims to reveal and promote awareness of STEM in people’s everyday lives and to highlight innovation and industry in the region. They deliver an exciting and varied programme of events for all, providing development opportunities through learning, discussion and volunteering. CSES brings together STEM professionals and those who have a general interest, providing a social and professional network for this large and important group of people.

Central to the mission is inspiring young people to build careers in STEM. CSES provides and coordinates STEM education activity in Essex, for primary and secondary students both at school and at home. Activities include clubs, competitions, bursary support and volunteer work in schools. This is critical to maintaining the UK’s industrial skills base.

The network connects key stakeholders – including local government, businesses, the education sector and the public – to collaborate on the issues, sectors and technologies that drive innovation and industry in the region. This is facilitated through a programme of regular talks, friendly social events and more formal conferences.

CSES is very much part of local history, having been formed as the Chelmsford Engineering Society in 1920 by representatives of the local companies (including the world-famous Marconi, Hoffman and Crompton). The society and its members seek to celebrate, preserve and educate people about our region’s renowned engineering and industrial heritage. CSES is a registered charity.
