If you are a Croydon resident and are unable to get an urgent appointment at your GP surgery you can call NHS 111 for an assessment of your problem. If you then need to see a GP NHS 111 can book an appointment for you to be seen at one of the three new GP hubs in Croydon which are open 8am to 8pm, 7 days a week, 365 days a year. You can also be seen at a GP Hub without an appointment but may have to wait.
