When you call, ask what referral paperwork is required and whether a GP letter must arrive before the visit. Ask what is billed separately, such as the study, the report, or a follow-up appointment. Ask what kind of sleep study is offered, where it takes place, and whether you sleep there overnight. Confirm the cancellation policy, since missed-appointment fees differ between clinics. If you are travelling from another town, confirm parking, public transport and the exact entrance before the day. If telehealth is offered, ask which parts of the assessment can be done remotely and which need a visit. If the practice sits inside a larger medical center, ask which building and floor to go to. Confirm fees, availability and location directly with the practice, as directory listings are not updated in real time.
