NHS Sleep study waiting times
Also called: sleep test, respiratory sleep study, polysomnography.
A sleep study records your breathing, oxygen levels and other signals overnight — often with equipment you take home — to look at how you breathe while asleep. It is used to investigate suspected obstructive sleep apnoea and other sleep-related breathing problems, often prompted by snoring, pauses in breathing or daytime sleepiness. There is no single national wait: it depends heavily on which hospital you are sent to, and the spread between hospitals is large. Below, the NHS trusts and independent providers reporting Sleep study to NHS England are ranked by median wait, shortest first.

Median wait and the percentage of patients seen within 6 weeks — the NHS operational standard for diagnostics. Hospitals with very few patients waiting are excluded so a median is meaningful.
Can I choose where I have my Sleep study?
For a planned, non-urgent diagnostic test you can ask. If your GP refers you to a consultant-led service, you have a legal right, with exceptions, to choose the provider — including one with a shorter wait. For a test your GP orders directly, ask your GP whether you can have it at a different hospital. Most people are never told this and go to their nearest by default. If the test leads to a referral, you can also compare NHS waiting times for treatment at hospital trusts in England.
Where these numbers come from
Waits are from NHS England's monthly Diagnostic Waiting Times and Activity (DM01) statistics, for September 2026. Each figure is the provider's median wait for that test; “within 6 weeks” is the NHS operational standard. Nothing here is medical advice — the site surfaces the published data so you and your GP can use it.
Frequently asked questions
- How long is the NHS wait for Sleep study?
- There is no single national wait — it depends on which hospital you are sent to. Sleep study waits vary between hospitals, sometimes several-fold, so the useful thing is to compare your own area. The table above ranks the NHS trusts and independent providers reporting Sleep study to NHS England, shortest median wait first, from NHS England's DM01 diagnostic figures.
- Can I choose which hospital does my Sleep study?
- For a planned, non-urgent test, you can ask. If your GP refers you to a consultant-led service, you have a legal right, with exceptions, to choose the provider, including one with a shorter wait — the NHS Right to Choose. For a test your GP orders directly, ask your GP whether you can have it at a different hospital. Most people are never told this and go to their nearest by default. It does not apply to urgent or emergency tests.
- What does "seen within 6 weeks" mean for Sleep study?
- Six weeks is the NHS operational standard for diagnostic tests — patients should wait no longer than that. The "within 6 weeks" figure for each hospital is the share of its patients who met that standard; the median is the typical wait. Both come from NHS England's monthly DM01 statistics.
