What is being counted?
These are waiting-list records for the named service or test. A person can appear on more than one list, so the totals are not necessarily individual people.

What does this say about the wait for a test?
In July 2026, the published proportion already waiting six weeks or longer ranged from 0% to 90.4% across 110 reporting providers.
These percentages describe entries on test waiting lists. They measure time already spent waiting, not how much longer you will wait. Ask the service about your clinical priority, next appointment and treatment date.
Range of provider percentages for the latest common reporting period shown here; not a patient-weighted national average or a ranking. Check each provider’s number of eligible records, particularly small groups.

What do these numbers tell me?
They show pressure on a service’s waiting list at a past reporting date. Use them to prepare questions when discussing your options.
How long have they already waited?
A waiting band describes time that had already passed at the end of the month. It does not show the remaining wait or promise an appointment within that band.
What should I ask next?
Ask which team and location would handle your referral, whether the service is appropriate for you, and its current expected wait. A trust’s figures may cover several hospitals or clinics.
Understand your referral optionsWhat to check before choosing
- Confirm that the provider currently offers the exact service, procedure or test you need.
- Check the referral route, the place you would attend and whether the service is NHS-funded for your referral.
- Ask how published waiting-list figures relate to your referral and clinical priority.
- Consider repeat journeys and accessibility alongside the service evidence.
