In order to be eligible for the Hillingdon service, you need to be aged 18 years and over and you must be registered with a Hillingdon GP. Please be aware that we are not an urgent service and therefore there may be some wait to be seen. If you have recently attempted suicide, are feeling suicidal, or unable to keep yourself safe, please call our urgent advice line (0800 0234 650) so that more timely support can be arranged for you. This line is open 24hrs a day. Alternately, you can contact your GP for an urgent review of your care or visit your local Accident & Emergency Department.
