Getting diagnosed with POTS in the UK
The realistic pathway from GP to specialist for POTS in the UK — what to ask for, what tests to expect, and where the bottlenecks tend to be.

Start with your GP
The NHS route to a POTS diagnosis goes through primary care. Book a double appointment if you can — you have a lot of ground to cover. Bring at least four weeks of symptom tracking (a PotsTrack PDF, a spreadsheet, or a careful notebook — anything that shows pattern not anecdote).
Three things to ask for, explicitly:
- Blood tests to rule out the common alternatives — full blood count, U&Es, TFTs, ferritin, vitamin D, fasting glucose, B12. These exclude anaemia, thyroid issues and deficiencies that present similarly.
- A resting 12-lead ECG to rule out inappropriate sinus tachycardia and arrhythmia.
- A referral. To cardiology if your symptoms are predominantly cardiac; to neurology if predominantly autonomic; to a dysautonomia-aware specialist where available. Mention POTS by name. Ask which centres your ICB will fund a referral to.
The realistic waiting times
Cardiology and neurology waiting lists in the UK in 2026 are typically months, not weeks, depending on region. POTS-specialist clinics are concentrated in a handful of teaching hospitals (London, Newcastle, Sheffield, Cambridge), so onward referral adds time on top.
During the wait, the most useful thing is to track. A six-month log of standing-test deltas + symptoms + triggers is the single biggest accelerator at the actual appointment.
The private option
A private consultation with a dysautonomia-aware specialist costs £200-£400 and can compress the timeline by months. Two caveats:
- Any investigations they order (tilt-table test, autonomic function tests) usually have to be done at their facility, adding cost. A private tilt-table test runs around £700-£1200.
- A private diagnosis does not automatically unlock NHS-funded management. Your GP can sometimes prescribe based on the private letter, sometimes not, depending on the medication and the ICB. Ask before you book.
What the diagnosis looks like when it comes
A POTS diagnosis in the UK is clinical — a clinician confirms (a) sustained heart-rate criterion on a standing test, (b) chronic symptoms ≥3 months, (c) other causes excluded. You don't need a positive tilt-table test to be diagnosed; a standing test plus the clinical picture is enough for many specialists. The letter from the specialist is the artefact that follows you through the rest of the NHS.
