Stress ECG Test UK (2026): Costs, What It Shows & How to Book
A stress ECG — also called an exercise ECG, treadmill test or exercise tolerance test — measures how your heart performs under exertion. Here’s what a private one costs, what it shows, the DVLA angle, and how it compares to other heart tests.
Short answer
A stress ECG (exercise ECG / treadmill test) records your heart’s electrical activity while you walk on a treadmill or cycle, to see how it copes with exertion — picking up problems a resting ECG can miss. Privately it typically costs £260–£500, takes 15–30 minutes, and uses the standard Bruce protocol. It’s commonly used to investigate exertional chest pain, assess known heart disease, and for DVLA, taxi (PCO) and aviation licensing. Most comprehensive health insurance covers it when referred and clinically needed.

What is a stress ECG?
A stress ECG goes by several names — exercise ECG, treadmill test, exercise tolerance test (ETT), or simply “stress test.” All describe the same thing: an electrocardiogram (ECG) recorded while you exercise, rather than at rest. Electrodes on your chest track your heart’s electrical activity as the effort gradually increases, alongside continuous blood pressure monitoring.
The point is that some heart problems — particularly reduced blood flow through narrowed coronary arteries — only show up when the heart is working hard. A resting heart check might look normal, while a stress ECG reveals the issue under load.

Private stress ECG costs in the UK (2026)
Price depends on the clinic, location, and whether a cardiologist consultation is included. These are indicative 2026 ranges — always confirm with the provider, as a test bundled with a consultation costs more:
| Provider / option | Typical price (2026) |
|---|---|
| Stress ECG (test only) | £260–£400 |
| Specialist cardiology clinic (with review) | £400–£600 |
| DVLA / PCO / aviation licensing test | £300–£500 |
| With cardiology consultation | £450+ |
| Insurance (referred & pre-authorised) | Usually covered |
How the test works
A stress ECG uses the standardised Bruce protocol, so results are comparable across clinics:
- Electrodes are attached to your chest and a blood-pressure cuff to your arm. A resting ECG is taken first.
- You start walking on a treadmill (slowly) or cycling. Every 3 minutes the speed and incline step up.
- The aim is to reach your target heart rate (around 85% of 220 minus your age), while the team watches your ECG, blood pressure and symptoms.
- The average person walks for around 9 minutes; the test is stopped if you hit the target, develop symptoms, or your ECG/blood pressure changes.
- A recovery period is monitored, and a cardiologist reviews the trace — often with results available the same day.
What does a stress ECG show?
- Reduced blood flow to the heart muscle during exertion (a sign of narrowed coronary arteries).
- Exercise-induced arrhythmias (irregular rhythms that appear under load).
- How your blood pressure responds to exercise.
- Your exercise tolerance — useful after a heart attack, stent or for fitness-to-drive assessments.
- Whether symptoms like chest pain or breathlessness are reproduced by exertion.

If a stress ECG leads to further heart tests or treatment, the right cover gets you seen fast.
Compare ProvidersWhen you might need a stress ECG
A doctor may recommend one if you have:
- Chest pain or discomfort on exertion
- Unexplained breathlessness during activity
- Palpitations or a suspected exercise-related arrhythmia
- A family history of coronary artery disease
- Known heart disease (e.g. after a heart attack or stent) needing assessment
- A need to certify fitness to drive or fly (licensing)
DVLA, taxi (PCO) and aviation licensing tests
One of the most common reasons people book a private stress ECG is for licensing. The DVLA (for Group 2 / HGV / bus licences), taxi/private-hire (PCO) authorities and the Civil Aviation Authority often require an exercise tolerance test to certify cardiac fitness. For a standard DVLA exercise test, you typically need to complete 9 minutes on the Bruce protocol without significant ECG changes to pass. Private clinics offer these quickly — often within days — with the report in the required format. If this is your reason for testing, confirm the clinic is experienced with your specific authority’s requirements before booking.
Accuracy and limitations
It’s important to be realistic about what a stress ECG can and can’t do:
Where the stress ECG still earns its place: assessing known disease, exercise capacity, rhythm under exertion, and licensing — and as a quick, widely available first-line test.
How to prepare
- Wear comfortable clothes and trainers — you’ll be walking briskly on a treadmill.
- Avoid a heavy meal for about 2 hours beforehand.
- Continue your usual medications unless your doctor specifically tells you to pause something (some heart drugs affect the result).
- Allow extra time for set-up and a monitored recovery period after exercise.
Does health insurance cover a stress ECG?
Most comprehensive private health insurance policies cover a stress ECG when it’s referred by a GP or consultant and clinically necessary, with pre-authorisation. A few points:
- Outpatient cover is usually what pays for diagnostic tests like this — check your limits.
- Licensing tests (DVLA etc.) are generally not covered, as they’re not for treating a medical condition — you’ll self-pay.
- Pre-existing conditions are typically excluded — see the rules here.

What happens if results are abnormal?
An abnormal or inconclusive stress ECG doesn’t necessarily mean heart disease — but it usually prompts further testing for a clearer answer. Depending on findings, your cardiologist might arrange a private echocardiogram, a Holter monitor or event monitor for rhythm, a CT coronary angiogram, or a cardiac MRI. A fast private pathway means you get those answers in days rather than waiting. Browse all options in the diagnostics hub.
The bottom line
A stress ECG is a quick, affordable (~£260–£500) way to see how your heart copes under exertion — ideal for investigating exertional symptoms, assessing known heart disease, and meeting DVLA or other licensing requirements. It’s not the last word on coronary artery disease, so an abnormal result usually leads to more detailed tests. If you want fast access to a stress ECG and any cardiac follow-up it triggers, the right health insurance covers the pathway and skips the NHS wait.

Stress ECG FAQs
How much does a private stress ECG cost in the UK?
Typically £260–£400 for the test alone, or £400–£600 at a specialist cardiology clinic including a consultant review. DVLA and other licensing tests are usually £300–£500 and are self-paid. Confirm exactly what’s included when booking.
What is a stress ECG also called?
An exercise ECG, treadmill test, exercise tolerance test (ETT) or simply a “stress test.” They all refer to an ECG recorded while you exercise on a treadmill or bike, usually using the Bruce protocol.
How long does a stress ECG take?
The whole appointment is usually 15–30 minutes including set-up and a monitored recovery period. The exercise itself averages around 9 minutes, increasing in intensity every 3 minutes until you reach your target heart rate or need to stop.
Is a stress ECG safe?
Yes — it’s supervised throughout by trained staff who monitor your ECG, blood pressure and symptoms, and stop the test if needed. Mild fatigue, breathlessness or dizziness can occur, but serious complications are rare.
What should I wear and how do I prepare?
Wear comfortable clothes and trainers suitable for brisk walking, avoid a heavy meal for about 2 hours beforehand, and continue your usual medications unless your doctor tells you otherwise. Allow extra time for set-up and recovery.
Will insurance cover my stress ECG?
Most comprehensive policies cover it when referred and clinically necessary, usually under outpatient cover and with pre-authorisation. Licensing tests (e.g. for the DVLA) are generally not covered as they aren’t for treating a condition, and pre-existing conditions are typically excluded.
What happens if my stress ECG is abnormal?
An abnormal result usually leads to further tests for a clearer picture — such as an echocardiogram, a Holter or event monitor, a CT coronary angiogram, or a cardiac MRI. It doesn’t on its own confirm heart disease, as stress ECGs have a notable false-positive rate.
Can I get a stress ECG for a DVLA or taxi licence?
Yes — private clinics commonly provide exercise tolerance tests for DVLA (Group 2/HGV/bus), taxi/PCO and aviation licensing, often within days. A standard DVLA test typically requires completing 9 minutes on the Bruce protocol without significant ECG changes. These are self-funded.
