The association said a number of reports were received from tenants who were recently approached by people claiming to carry out work on behalf of the organisation.
Residents are encouraged to always check ID cards before allowing people into their home, Hackney Homes said, adding that its staff and contractors carry identification cards on all visits.
Hackney cabinet member Cllr Philip Glanville said: “The safety of our residents is paramount to us.
“We ask all residents to be cautious when opening the door to someone they do not recognise and to be aware of callers who try to use distraction techniques to encourage tenants to leave their home.”
Residents who are unsure of a Hackney Homes visitor or want clarification regarding a home visit are asked to call the repairs contact centre on 020 8356 3691.
