It is worth confirming the referral rules first, since some practices require a GP letter and others do not. Ask what is billed separately, such as the study, the report, or a follow-up appointment. Ask how the study is arranged, how long the wait is for a test date, and when the results are discussed. Confirm the cancellation policy, since missed-appointment fees differ between clinics. If telehealth is offered, ask which parts of the assessment can be done remotely and which need a visit. If you need an interpreter, ask whether one can be arranged for the appointment. Find out whether the practice runs a structured sleep program and how many sessions it involves. Details on this page come from public records and can change, so confirm them with the practice before you travel.
