Sleep Studies in the UK: The NHS Pathway

In short

In the UK, the route to a sleep study runs through your GP. If obstructive sleep apnoea is suspected, the GP refers you to a hospital sleep or respiratory clinic, which usually arranges an overnight home sleep study first; a full in-lab study is reserved for complex cases. NICE guideline NG202 (2021) sets out who should be investigated and treated, and CPAP is supplied and monitored by the NHS after diagnosis. Sleepy drivers must stop driving until assessed, and may need to inform the DVLA.

The NHS path to a sleep study

See your GP. Describe snoring, witnessed pauses, waking unrefreshed and daytime sleepiness. GPs commonly use the Epworth Sleepiness Scale and STOP-Bang to decide on referral.
Referral to a sleep or respiratory clinic. Referral follows NICE guideline NG202. People whose sleepiness affects driving or safety-critical work are prioritised.
A home sleep study. Most clinics send equipment for an overnight study in your own bed (respiratory polygraphy or oximetry); in-lab polysomnography is used for complex cases.
Diagnosis and treatment. If moderate-to-severe obstructive sleep apnoea is confirmed — or mild OSA with symptoms affecting quality of life — NICE recommends fixed-level CPAP as first-line treatment, supplied and monitored by the NHS.

What NICE NG202 says

NICE guideline NG202, published 20 August 2021, covers investigation and management of obstructive sleep apnoea/hypopnoea syndrome in people aged 16 and over. Key points for patients: referral for investigation should follow the guideline; people with mild OSA whose symptoms affect their quality of life should be offered CPAP; and anyone with excessive sleepiness should be advised not to drive until assessed by a specialist.

Driving and the DVLA

If sleep apnoea causes excessive sleepiness, you must not drive until you have been assessed and treated, and you may be legally required to inform the DVLA. Clinics will tell you what applies to your situation; the DVLA publishes the current rules.

Private sleep clinics

Private clinics across the UK offer sleep studies without an NHS wait. Results still need specialist interpretation, and NHS clinics may need to re-assess before providing CPAP on the NHS. Ask what is included and whether the report will be accepted by your NHS trust.

Questions people ask

Is a sleep study free on the NHS?

Yes. NHS sleep studies, and CPAP treatment when it is recommended, are free at the point of use after GP referral.

Can I get a home sleep test on the NHS?

Usually the first test is a home study — you collect or receive the equipment and wear it for one night in your own bed. In-lab studies are used for more complex cases.

How long is the NHS wait for a sleep study?

It varies by trust. NHS England publishes diagnostic waiting-time statistics; your GP practice or the clinic can tell you the current local position.
