It is worth confirming the referral rules first, since some practices require a GP letter and others do not. Ask for the total expected cost before booking, separating the consultation from any study or device fee. Check whether home testing is available or whether the study has to be done overnight at the practice. If you are travelling from another town, confirm parking, public transport and the exact entrance before the day. 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. If you need an interpreter, ask whether one can be arranged for the appointment. Treat the details here as a directory snapshot and confirm anything time-sensitive with the practice.
