Welcome to the Essential Services Access Network (ESAN) website.

ESAN exists to try to improve access to vital services, particularly for consumers in vulnerable circumstances.  We cover energy, communications, water and financial services.

Sustainability First has taken over the running of ESAN since June 2025 but information about ESAN activities will continue to be hosted on this website.
