What is a private sleep study?
A sleep study measures your breathing, oxygen levels, and other body signals during sleep. It helps detect disorders like OSA, narcolepsy, and certain movement disorders. In the UK private sector, most patients start with a Home Sleep Apnoea Test (HSAT), while more complex cases may need in-lab polysomnography (PSG).
Who should consider a sleep study?
- Loud, regular snoring with pauses or choking sounds during sleep
- Excessive daytime sleepiness or morning headaches
- High blood pressure, heart rhythm problems, or type 2 diabetes
- Family history of sleep apnoea
- Professional drivers or safety-critical roles needing rapid assessment

What happens after a sleep study?
Your results will include an Apnoea–Hypopnoea Index (AHI) score:
- 5–14: Mild OSA
- 15–29: Moderate OSA
- 30+: Severe OSA
Treatment options include CPAP/APAP, mandibular advancement devices, positional therapy, and lifestyle changes. Severe or symptomatic cases are usually treated promptly.
When a sleep study may not be necessary
If your symptoms are mild and no risk factors are present, your GP may recommend lifestyle changes first. For specific issues (e.g., insomnia without suspected apnoea), other assessments may be more appropriate.
FAQs – Private sleep studies
Do I need a GP referral?
No — most private providers accept self-referral, though insurance claims may require one.

How often should I be tested?
Once for diagnosis. Repeat studies are usually only done if symptoms change or to reassess treatment.
Are results shared with my NHS GP?
You can request this to ensure continuity of care.
