People living with HIV in England, as well as non-UK born and individuals without residency, can access free HIV care at any service in England. We investigated reasons for transfer of care to three London HIV units by asking all patients transferring to fill in a questionnaire exploring reasons for leaving their previous centre and reasons for choosing the new service. A total of 111 patients completed the questionnaire. The majority of patients transferred from abroad to London HIV units, compared to within the UK. The main reason for leaving their current service was location, which was also the main reason for choosing the service they transferred to. The results of this audit can be used to improve all services to ensure any concerns patients may have are eliminated and provide healthcare tailored to patients’ needs.
