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 trusts is large. Below, every English NHS trust that reports Sleep study is ranked by its median wait, shortest first.

Sleep study waits by hospital, shortest first
Median wait and the percentage of patients seen within 6 weeks — the NHS operational standard for diagnostics. Trusts with very few patients are excluded so a median is meaningful.
Can I choose where I have my Sleep study?
For a planned, non-urgent diagnostic test you often can. In England you have a legal right, when your GP refers you, to ask to be seen at a different hospital — including one with a shorter wait. Most people are never told this and go to their nearest by default.
Where these numbers come from
Waits are from NHS England's monthly Diagnostic Waiting Times and Activity (DM01) statistics, for July 2026. Each figure is the trust'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 NHS trusts, sometimes several-fold, so the useful thing is to compare your own area. The table above ranks every English NHS trust that reports Sleep study, 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, often yes. In England you have a legal right, when your GP refers you, to ask to be seen at a hospital with a shorter wait — the NHS Right to Choose. 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.
