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 which sleep study the practice would use — home testing or an overnight study in a lab — and what each involves. Confirm the cancellation policy, since missed-appointment fees differ between clinics. Ask what to bring: a medication list, any referral letter, a sleep diary, and results from earlier studies. Ask who reviews the study results and when you will be told what they show. It is worth asking whether the practice deals with the kind of sleep problem you have, since some clinics focus on particular conditions. Treat the details here as a directory snapshot and confirm anything time-sensitive with the practice.
