A sleep study monitors breathing and rest overnight, usually to diagnose sleep apnoea. At the end of June 2026, 36,149 people across England were on the waiting list for sleep studies, and 29% had waited longer than the NHS’s six-week target — but where you live changes that wait dramatically, and private scans are available within days.

A wait beyond six weeks for sleep studies is counted as a breach of the NHS standard. In the trusts above, most patients had waited longer than that — which is exactly where going private saves the most time.
Skip the queue with private treatment
A long wait for sleep studies is a wait for the answers a diagnosis brings. Private cover can have you seen by a consultant in days, not months. It will not pay for a condition you are already waiting on, so arrange it before a problem starts — compare cover, see if it is worth it, or get a free quote.
Frequently asked questions
What does going private cost for sleep studies? Private hospitals publish self-pay prices and can usually book you in within days. Private medical insurance covers diagnostic tests in full when you are referred, provided the problem is not one you already have.
Why do NHS sleep studies waits vary so much? Capacity, staffing and demand differ by trust, so the wait for the same test can be a few days in one place and several months in another.
