At-home sleep study, a WatchPAT or Nox device that diagnoses obstructive sleep apnoea in your own bed.
A modern take-home sleep study uses a compact device (WatchPAT, Nox T3, ApneaLink) worn overnight to diagnose obstructive sleep apnoea (OSA). Same-week private pathway with sleep-physician review and CPAP initiation if needed.
- Definition — portable home-based sleep apnoea test
- Devices: WatchPAT One, Nox T3, ApneaLink
- Diagnoses moderate-severe OSA reliably
- AASM Type III or IV device
- Best for patients with high pre-test probability
- In-lab PSG required for suspected central apnoea or complex cases

The problem
A home sleep study is only as good as the physician who overreads it.
The device produces a trace — the physician produces the diagnosis. We route you to a consultant sleep physician who overreads every study, not a software-only score.
-
Snoring and daytime sleepiness?
We arrange a WatchPAT or Nox study within the week — no six-month lab waitlist.
-
Witnessed apnoeas at night?
A single well-fitted night at home usually confirms or excludes OSA.
-
CPAP or MAD — which suits?
Physician review turns the numbers into a plan you can act on this month.
The journey
From enquiry to report — what happens, in order.
One clinician from first message to report — usually within a week.

Analysis and report
- 01
Before
You tell us what’s going on
A short, confidential form. Snoring, witnessed apnoeas, daytime sleepiness, driving, referral or insurer if you have them.
- 02
Before
Sleep-physician consultation
A brief consult decides whether an at-home study is the right test — or whether in-lab polysomnography is the safer route.
- 03
Before
Home-testing device provided
WatchPAT One, Nox T3 or ApneaLink dispatched or collected — with a short setup video and a direct number to call if anything sticks.
- 04
The night
Fit and wear it in your own bed
Fit the finger, chest and nasal sensors before sleep. One full night in your own bed — no clinic stay, no wires trailing across a hotel room.
- 05
The night
Return the device next morning
Drop-off, courier collection or return-post pack — whichever suits. Data uploads automatically.
- 06
After
Automated analysis and physician review
Software scores the raw signal; a consultant sleep physician overreads every trace — the numbers are not the report on their own.
- 07
After
Report within 5–7 days
A written report with AHI, ODI and a plan — including CPAP initiation, MAD pathway or ENT referral if indicated.
Typical end-to-end: 7–10 days. Urgent cases: same-week.
What it shows
What an at-home sleep study actually measures.
A home study answers a specific question — do you have OSA, how severe, and what shape does it take across the night.
-
Apnoea-Hypopnoea Index (AHI)
The headline number: events per hour of sleep — mild (5–14), moderate (15–29), severe (30+).
-
Oxygen desaturation index
How often and how deeply your oxygen dips overnight — a key marker of physiological impact.
-
Snoring pattern
Intensity, duration and clustering — useful context for partners and for pathway choice.
-
Body-position dependency
Whether events are worse supine — positional therapy is meaningful for a subset of patients.
-
REM-related events
Some patients have events almost exclusively in REM sleep — the report calls this out.
-
Sleep stage estimation (WatchPAT)
Peripheral arterial tonometry infers sleep architecture — an advantage over pure oximetry devices.
-
Pulse and respiratory patterns
Overnight heart-rate variability and respiratory effort inform the wider clinical picture.
-
Red flag: severe OSA (AHI > 30) with sleepiness — urgent CPAP pathway
Severe disease with daytime sleepiness is fast-tracked to CPAP initiation, not booked for months.
Red flags
When to prioritise a sleep study — and when the home route is not enough.
Any of these warrants a low threshold to investigate. Some warrant in-lab polysomnography rather than a home study.
-
Excessive daytime sleepiness
-
Witnessed apnoeas
-
Occupational driving (HGV, PCV, taxi)
-
Heart failure with OSA
-
Refractory hypertension
-
Nocturnal arrhythmia
-
Suspected central sleep apnoea
-
Complex REM behaviour disorder
-
Overlap syndrome (OSA + COPD)
Device options
Not every home sleep study is the same.
What each device on your referral is actually for.
-
WatchPAT One
Single-use, finger-worn device using peripheral arterial tonometry — AASM Type III with sleep-stage estimation.
-
Nox T3
Reusable multi-channel Type III device — nasal cannula, chest and abdominal effort belts, oximetry.
-
ApneaLink Air
Lightweight AASM Type IV screening device — nasal flow, oximetry, effort. Good for high pre-test probability.
-
HSAT + physician consult
Device plus a same-week consultant sleep-physician appointment to interpret and plan.
-
HSAT + CPAP initiation
Device, physician review and CPAP set-up with a 30-day trial and remote titration.
-
HSAT + MAD assessment
For mild-to-moderate OSA and snoring — device plus a specialist dentist for a mandibular advancement device.
-
Repeat study on treatment
Objective check that CPAP, MAD or positional therapy is actually working.
-
In-lab polysomnography (referral)
When the home study is inconclusive or central apnoea is suspected — we refer on rather than repeat.
Next steps
What we do with the result.
Every finding maps to a concrete option — not a leaflet.
-
Lifestyle advice
Weight loss, alcohol reduction and sleep hygiene — meaningful for mild OSA and every severity.
-
Positional therapy
For patients whose events are almost exclusively supine — a targeted, low-cost first step.
-
CPAP for moderate-severe OSA
Continuous positive airway pressure — the gold standard, initiated with a 30-day trial.
-
Mandibular advancement device
Custom MAD from a specialist dentist — for mild-to-moderate OSA and simple snoring.
-
ENT referral
Surgical options for anatomical obstruction — turbinate, palate, tongue-base or hypoglossal-nerve pathways.
-
Bariatric surgery discussion
For patients with BMI > 35 and OSA, a formal bariatric conversation is often the highest-yield lever.
-
Repeat study on treatment
An objective HSAT after CPAP or MAD confirms adequate treatment — not just symptom improvement.
-
DVLA notification
When OSA is confirmed with excessive sleepiness, DVLA notification is a legal obligation — we help you through it.
Our vetted London network
A small panel of sleep services, we picked them.
Partners across central, north, west and south London. Not listed publicly — introductions are made privately, once we understand your case.
Selection criteria
How we choose every sleep service in our network.
-
Consultant sleep physicians (respiratory or neurology), not generalists
-
AASM Type III or IV devices — WatchPAT, Nox T3, ApneaLink
-
Every trace overread by a physician — not software-only reporting
-
Onward CPAP, MAD or ENT pathway if the study is positive
Safety and eligibility
When a home study fits — and when it doesn’t.
An at-home sleep study is a good test for the right patient. The practical points are pre-test probability, driving obligations, and where the study’s limits are.
-
Best for high pre-test probability
HSAT is validated where OSA is the most likely diagnosis. It is not a general sleep screen.
-
Not for suspected central apnoea
Suspected central sleep apnoea, complex REM behaviour disorder or narcolepsy need in-lab polysomnography.
-
One good night is usually enough
A single technically adequate night is sufficient in most cases — we repeat if the trace is poor.
-
No preparation beyond usual sleep
Take medication as normal, avoid alcohol and heavy meals close to bedtime, sleep as you usually would.
-
Occupational drivers — declare it
HGV, PCV and taxi drivers must notify the DVLA once OSA is confirmed with excessive sleepiness.
-
Overlap syndrome caveat
OSA plus COPD (overlap syndrome) needs a fuller assessment than a home study alone.
-
A normal HSAT is not a full clear
A negative home study in a symptomatic patient can miss disease — in-lab PSG may still be needed.
-
CPAP is the gold standard
For moderate-severe OSA, CPAP outperforms every alternative — adherence is the practical challenge, not efficacy.
-
Bring partner observations
Witnessed apnoeas and snoring patterns from a bed-partner materially sharpen interpretation.
Reading your report
An at-home sleep study report can look intimidating. It isn’t.
Whatever the finding, the report keeps to the same four parts.
A quiet reminder
The report is written for your doctor, not for you — and that’s normal.
If you would like us to talk you through it before your follow-up, just ask.
- 01 Header
Indication and symptom summary
Your details, the Epworth sleepiness score, driving status and the reason for the study.
- 02 Technique
Device, channels and study quality
Which device, which channels, total valid recording time and any technical caveats.
- 03 Findings
AHI, ODI, position and REM breakdown
The headline indices with supine vs non-supine and REM vs non-REM sub-analyses.
- 04 Impression
The conclusion: read this first
Normal, mild, moderate or severe OSA, and the concrete next step — CPAP, MAD, positional, or in-lab PSG.

Cover depends on your policy and provider; we confirm with your insurer before booking.
Frequently asked
Everything we get asked about at-home sleep studies.
Quick answers on cost, referrals, home vs in-lab studies, and what happens if the study is positive.
-
Can I really diagnose sleep apnoea from home instead of a sleep lab?
Yes — for most adults with typical snoring, witnessed pauses or daytime sleepiness, a home study is the recommended first step. It records nasal airflow, chest and abdominal effort, oxygen and pulse (or peripheral arterial tone on WatchPAT), which is enough to calculate the AHI and confirm obstructive sleep apnoea; we courier the device across London and turn round a consultant sleep-physician report within 5–7 days.
-
How is a home study different from an in-lab sleep study?
In-lab polysomnography adds EEG, EMG, EOG and video — the full picture of sleep architecture and movement. Home studies (AASM Type III and IV) are simpler but well-validated for straightforward OSA. Central apnoea, REM behaviour disorder, narcolepsy and complex cases still need the lab.
-
How much does a private at-home sleep study cost in London?
A WatchPAT or Nox T3 home study is typically £350–£650 in our network; adding a consultant sleep-physician consult or CPAP initiation raises the price. We confirm a firm figure within one working day.
-
Do I need a referral?
Most providers accept self-referral for an at-home sleep study. If your insurer needs a formal referral we can arrange a fast-track private GP or sleep-physician consult.
-
What if the study says I have severe OSA?
Severe OSA (AHI > 30) with excessive daytime sleepiness is fast-tracked to CPAP initiation. Most patients see a meaningful improvement within days to weeks of a well-titrated mask.
-
How quickly will I get results?
The device is analysed and overread by a consultant sleep physician, with a formal written report within 5–7 days. Urgent cases are expedited.

In practice, in London
Booking at home sleep study privately in London — what actually happens
With at home sleep study, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. The NHS route for at home sleep study is thorough, but the queue is real. Most patients we speak with have been told to expect anywhere from a handful of weeks to several months, depending on their local trust and how the referral is graded. Going private in London usually collapses that window to a matter of days — often the same week if the diary allows. It isn’t about jumping a queue so much as buying time back while you still have the flexibility to plan around it.
Once you’re in the private system for at home sleep study, the pace picks up noticeably. Consultant slots run to time, imaging is usually available in the same building or a short walk away, and the report comes back typed and detailed. It’s the coordination that tends to feel different — one person on the other end of the phone, not a switchboard. For at home sleep study specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
The value of going through a concierge for at home sleep study isn’t access — anyone with an insurer or a credit card can get a private appointment in London. The value is knowing which consultant reads this particular presentation best, which unit turns reports around fastest, and which pathway won’t hit a dead end if the findings point somewhere unexpected.
