Full diagnostic sleep studies, reported within 7 to 10 days.
We investigate and treat sleep disorders across London and Hertfordshire. That might mean a detailed overnight study, or one of the tests you can do at home. You don't need a GP referral. Request a study and we'll call you to arrange it.

When to think about a sleep study
A lot of what goes wrong with sleep happens when you're not aware of it. A sleep study records your breathing, oxygen levels, heart rhythm, limb movement and sleep stages over a full night, and it is the clearest way to understand what is happening during your sleep. If you recognise any of the symptoms below, it's worth talking to us.
- Snoring with witnessed pauses in breathing
- Daytime sleepiness despite adequate time in bed
- Falling asleep while driving or during work
- Unrefreshing sleep over a period of weeks or months
- Unusual movements or behaviours at night
- Night-time teeth grinding or jaw clenching
- A previous test reported as normal while symptoms continued
- Diagnosed sleep apnoea that CPAP has not resolved
What happens during an overnight study
You don't have to know which test you need. Your doctor will recommend an approach based on your symptoms, medical history and individual needs. An overnight study then gives us a detailed picture of what happens while you sleep.
Setting up
Our sleep physiologist sets up your study and fits the sensors before you go to sleep.
Through the night
While you sleep, the study records brain activity, eye movements, breathing, oxygen levels, heart rhythm and muscle activity, including leg and jaw movements. It also records video through the night.
Your results
We go through the whole night's recording in detail to help guide your care. Your results are reported within 7 to 10 days.
Which study is right for you
Which study we use depends on your symptoms and how much detail your diagnosis needs. We'll talk you through the options and explain where each one fits in your care.
Detailed Overnight Sleep Study (Nocturnal Video Polysomnography)
Tap to read moreThis study is done in hospital and gives a detailed picture of what happens while you sleep. It may help investigate daytime sleepiness that won't go away, disturbed breathing, unusual movements or behaviours at night, or symptoms nobody has explained yet. We also use it to look at night-time teeth grinding (bruxism) when a dentist or doctor needs a clearer picture.
