Home Sleep Study Service

Sleep Diagnostics · Home Sleep Studies

Why test at home?

I want every patient to be able to have their sleep study done at home. Sleeping in a hospital sleep lab — particularly the first night in a strange bed, wired up in an unfamiliar room — simply isn't representative of how you normally sleep. A study recorded in your own bed gives a much more honest picture of your sleep and breathing.

I also offer one, two or three night recordings on the more advanced devices, because there is considerable night-to-night variation in sleep and breathing. Capturing several nights lets us see what your body genuinely does, rather than what it happened to do on one unrepresentative night.

Below you can compare all of the options side by side, then read about each one in detail underneath.

Compare the sleep studies

Nox T3 / T3s and Nox A1 prices may be higher if you live a long way from the Greater London area, as the courier may charge more for the distance.

What every study includes

With all of these studies you receive the sleep study itself — the actual numbers and graphs of your recording — as well as the video and a short written report. You don't just get a summary: you see your real data.

So that you can understand and assess your own study, here are two short videos explaining how to read your results:

WatchPAT One — the simple, affordable screen

£295 · posted to you · single night

The WatchPAT One is our quickest and simplest home sleep test, and it is reliable for diagnosing obstructive sleep apnoea. It is the device used by many NHS sleep clinics, and it is medically approved diagnostic equipment that only needs a single night. The device is posted to you, used for one night, and then disposed of afterwards.

It is mainly intended for two situations: working out whether you are likely to need CPAP, or simply confirming that you do have sleep apnoea. With this study you also get a personalised 5-minute video from Professor Vik Veer — which you can watch in your own time — together with a short written report (around one paragraph) created by the leading sleep technologist in the country, Michael Storey.

In the £295 WatchPAT video, Professor Veer talks you through your results — what your numbers mean. He does not, in this short video, go into what to do next or what treatments are available.

If you would like that next step, look at the ISMA sleep clinic instead. The difference with ISMA is that you receive a personalised video from Professor Veer and a very long, detailed report written by Professor Veer himself — around 10+ pages — covering what your results mean and what to do about them. With ISMA you also get to see Natasha in our Harley Street clinic.

How it works

• Simple: order the test, wear the WatchPAT for one night at home — no time off work and no overnight clinic appointment.
• Rapid: the WatchPAT One transmits data automatically through the WatchPAT ONE app on your smartphone (free from the Apple App Store or Google Play).
• Reliable: the WatchPAT is the most widely used validated UK home sleep study, correlating at around 90% with the gold-standard polysomnography used in a sleep clinic.

Who should not use the WatchPAT

WatchPAT is suitable for diagnosing OSA in most adults, but it should not be used by:

• Patients with a permanent pacemaker (atrial pacing, or VVI without sinus rhythm)
• Adults with a BMI of 45 or above — please consult your GP before testing
• Children under 18 years old
• Anyone taking alpha blockers, or short-acting nitrates less than 3 hours before the study
• Those with sustained non-sinus cardiac arrhythmias

Acrylic nails, gel nails and nail polish affect accuracy — remove any nail coverings from the finger used for the pulse oximeter. If you have a cold or feel unwell, wait until you have recovered before testing.

SleepImage — three studies, raw data, low cost

£250 for three sleep studies · posted to you · +£50 per additional night

The SleepImage device is posted to you and gives you three sleep studies for £250, along with a short written report and access to the raw sleep-study data (as you get with all of these studies). It does not give positional or REM data, so it is less detailed than the Nox studies, but it is an economical way to record several nights.

If you want to add another night at a later date, simply keep the device and let us know — we can add another night for £50.

This is the only study where you do not receive a personalised video from Professor Veer — it comes with a short written report and your raw data instead. (Every other study on this page does include a personalised video.)

Nox T3 & Nox T3s — the most advanced home sleep study

1 night £850 · 2 nights £950 · 3 nights £1050 · couriered to and from your home

The Nox T3 and Nox T3s are much more advanced studies, and the Nox is the most advanced home sleep study available on the market. The Nox T3s additionally captures sleep stage and REM data. A three-night Nox T3s is the study I need before I can perform a drug-induced sleep endoscopy (DISE) — I need this high-resolution data first in order to do the DISE accurately.

The Nox sleep study is suitable for patients from 2 years old, with no upper age limit, making it ideal for children as well as adults. I offer one, two or three nights because there is considerable night-to-night variation in sleep and breathing — recording over several nights captures that detail and gives the most accurate information possible.

Because the device is so expensive it cannot be posted. Instead, it is couriered to your home; you use it for one to three nights; then the courier comes to collect it. That way you never need to travel to pick it up or drop it off — much more convenient. As with the other studies, you receive a personalised video from Professor Veer and a short written report from Michael Storey.

What the Nox T3 measures

The Nox T3 is an at-home assessment that records how your body functions during sleep — breathing patterns, oxygen levels, body position and snoring — giving a clear picture of your sleep quality without an overnight hospital stay. You may be offered a Nox T3 study if you have experienced:

• loud snoring, gasping, or choking during sleep
• daytime tiredness despite apparently adequate sleep
• pauses in breathing or irregular breathing during sleep
• frequent waking, restless legs, or limb movements
• a throat, nose or ear problem that may affect your breathing during sleep

It can help diagnose obstructive sleep apnoea, periodic limb movement disorder and restless leg syndrome, nose- and throat-related sleep disorders, snoring, and other sleep-related breathing disorders.

Setting up the Nox T3 — what to expect

Your device arrives with your details already programmed in, and most of the sensors already connected. In brief:

1. Position the device. Clip the Nox T3 to your clothing near your collar using the crocodile clips, with the display facing upwards. We ask you to wear it over clothing (a pyjama top or clean t-shirt) so it is not next to your skin.
2. Connect the belts. Clip the chest belt to the back of the device and wrap it around your chest just below the armpits; connect the abdomen belt to the abdomen sensor and position it around your belly button. Both belts should be snug but comfortable, and not twisted.
3. Pulse oximeter & finger probe. Put the oximeter on the wrist opposite the side you sleep on, place the finger probe on a finger (no nail varnish or acrylic nails), and tape the wire to your hand.
4. Cannula. Loop the cannula over your ears and under your chin with the nasal prongs in your nostrils, then push it into the pressure input on the side of the device.
5. Optional leg leads. Some people are asked to attach leg leads to look for restless leg syndrome and periodic limb movement disorder — let the team know beforehand if you'd like this.
6. Recording. The device turns on automatically at 10pm unless otherwise arranged; the screen goes blank but it is still recording. (If an "X" appears, the oximeter hasn't paired — turn the device off and on until a tick appears.)

Please remove nail varnish or acrylic nails before testing, take your medication as usual unless told otherwise, and do not smoke while wearing the equipment. Please be aware the device records live audio, and we need at least 4 hours of recording for a study to be valid. If you need the toilet in the night, leave the device running and just remove the finger probe to wash your hands. In the morning, remove the sensors, throw away the cannula, tape and belts, and return the device, oximeter and abdomen sensor to the box for the courier.

Nox T3s (3 nights) + Advanced UARS / TAB analysis

£1495 total — or a £445 add-on if you've already had a three-night study with us

This is a new service that Michael and I have created. It is particularly good for people who have had a relatively normal sleep study elsewhere but still feel they have a breathing problem. On top of a three-night Nox T3s recording, Michael manually scores the study and adds advanced physiological analysis using the new markers we have developed.

The £1495 total includes:

• Courier delivery to your home and courier return of the equipment
• A three-night Nox T3s home sleep study recording
• A short sleep study report
• Manual scoring and advanced physiological analysis
• TAB (Thoracoabdominal Asynchrony Burden), VB (Ventilatory Burden) and AB (Autonomic Burden)
• A detailed UARS-focused interpretation
• A 5-minute personal video explanation from Professor Vik Veer

If you have already had a three-day study with me, you can simply add on the £445 for this extra service to examine these additional markers (TAB / VB / AB) that we have invented.

To understand the science behind these markers, read more on the UARS & TAB / AB Diagnostic Service page.

International / External sleep study data re-interpretation

£1140 — for patients who already have their own sleep study raw data (EDF) file

Sometimes someone from abroad, or someone who has not done a sleep study with us, asks us to examine their study for TAB / VB / AB. We can do this — but the study must be three nights recorded on consecutive nights, and the data must come from a Nox T3s, Nox A1 or Somnomed device. You send us your EDF file, Michael completely re-scores it from scratch, and then we add our new sleep metrics.

This service includes:

• Full manual rescoring of the sleep study
• Advanced UARS physiological analysis
• TAB / VB / AB assessment
• A 5-minute personal video explanation from Professor Vik Veer

It does not include ongoing messaging support or a follow-up consultation — although a separate virtual consultation can be booked if further discussion is required. If you are not sure which type of study you have had, ask us or Michael and we can check before you order.

Nox A1 — full home polysomnography (PSG)

£1995 · Michael Storey sets it up at your home or hotel in the London area · one night

The Nox A1 is a full PSG service in which Michael Storey comes to your home, or your hotel in the London area, and sets up a complete polysomnogram for one night. This is the most advanced type of sleep study available, and it is excellent for picking up the full range of other sleep disorders — not just sleep-breathing disorders.

I still want this done at home wherever possible, because a study recorded in your own bed is far more representative of your normal sleep than a night in a hospital lab. The cost of £1995 includes the personalised video from Professor Veer and a short written report from Michael Storey.

Frequently asked questions

Prices shown are correct at the time of publication. Nox device studies may cost more for patients outside the Greater London area due to courier distance charges. These home sleep studies support, but do not replace, overall clinical judgement — if you have severe daytime sleepiness or symptoms suggestive of significant sleep apnoea, please seek a formal assessment promptly.
