The Royal Borough is asking residents who have a mental health condition, or who know of someone that does, for their views about local services.
It wants to hear what people think about mental health counselling and community support services, and any suggestions for how they could be improved to meet residents' needs.
Cllr David Gardner, the Royal Borough's Cabinet Member for health, social care and public health, said: "The positive mental health and wellbeing of our residents is a priority for the council. We work closely with a range of local partner organisations to ensure that people get the support that they need.
"This survey will help us to ensure that we plan our services to most closely reflect the needs of local people."
The survey runs until 29 April 2016. To take part go to www.royalgreenwich.gov.uk/mentalhealthsurvey or pick up a form at the Woolwich Centre reception at 35 Wellington Street, London SE18 6HQ.
