Private heart health check in London: which cardiac tests do you actually need?

11 minute read

Medically reviewed by Dr Ravi Assomull, Consultant Cardiologist – July 2026

Key takeaways

• Cardiovascular disease is among the UK's biggest killers, and its first symptom is sometimes its last - which is why checking before symptoms appear matters.
• A worthwhile heart check is consultant-led and staged: risk assessment and core tests first, advanced imaging only where results justify it.
• The core panel - blood pressure, advanced cholesterol testing (including lipoprotein(a)), ECG and echocardiogram - finds most silent problems.
• Screening pays off most from your 40s, earlier with a family history of heart disease or sudden death - and results should change what you do next, not just fill a PDF.

Most heart disease gives no warning until it is well established. Arteries narrow silently for decades; blood pressure and cholesterol do their damage without a single symptom; and some people's first sign of coronary disease is a heart attack. That is the uncomfortable arithmetic behind heart screening - and the reason "I feel fine" is reassuring but not conclusive.

The private market's answer is the "heart health check" or "cardiac MOT", and the offerings range from genuinely excellent to little more than expensive theatre. This guide - from a consultant cardiologist in London - explains which tests actually earn their place, who benefits most from screening, what results mean, and how to tell a rigorous check from a glossy one.

Who should have a heart health check?

Screening is not for everyone every year. It delivers the most value if any of these apply:

• You're over 40 and have never had your heart properly assessed. Risk rises with age, and the NHS Health Check - useful as far as it goes - does not include an ECG or any heart imaging.
• Heart disease runs in your family - a parent or sibling with a heart attack before 55 (men) or 65 (women), an inherited condition such as cardiomyopathy, or a relative who died suddenly and unexplained. Family history shifts risk more than almost any lifestyle factor, and warrants checking earlier and more thoroughly.
• You carry risk factors: smoking (current or former), diabetes, high blood pressure, raised cholesterol, kidney disease, obesity, significant stress or poor sleep - each compounds the others.
• You're returning to serious exercise after years away, or you're a masters athlete pushing hard - exertion is safe for almost everyone, but the exceptions are exactly what screening exists to find. (Our article on exercise-induced heart problems covers the warning signs.)
• You have niggles you've been rationalising - in which case you've left screening territory: read our guide on when to see a cardiologist, because symptoms change the pathway.

The tests that matter - and what each one finds

The foundation: history and risk assessment

Every worthwhile check begins with a consultant taking a proper history - family patterns, lifestyle, symptoms you didn't think counted - because test selection should follow your risk, not a fixed menu. This is the difference between screening and box-ticking, and it's why our checks start with the initial assessment rather than a scanner.

Blood pressure - properly measured

A single clinic reading is a poor measure: some people run high only in clinics ("white coat"), others only outside them. Where readings are borderline or inconsistent, a 24-hour ambulatory monitor settles the question definitively. Hypertension remains the single biggest modifiable driver of stroke and heart disease - finding it is the cheapest big win in medicine. (Home readers: our monitor guide shows how to measure accurately.)

Advanced blood testing - beyond the basic cholesterol number

A modern lipid panel goes further than "total cholesterol": LDL and HDL fractions, triglycerides, and crucially lipoprotein(a) - an inherited risk particle carried by roughly one in five people, largely unaffected by lifestyle, and absent from standard panels. Measuring it once changes risk calculations for life. Blood tests also cover diabetes (HbA1c), kidney and thyroid function - each a quiet contributor to cardiac risk. For the lifestyle side, see our guides to lowering cholesterol and metabolic health.

Electrocardiogram (ECG) - the electrical check

The resting ECG takes five minutes and screens the heart's electrical system: rhythm disturbances such as silent atrial fibrillation, conduction problems, electrical signatures of inherited conditions, and evidence of old, unnoticed damage. Cheap, painless, and occasionally life-saving - there is no good argument for a heart check that omits it.

Echocardiogram - the structural check

The echocardiogram is the workhorse of screening imaging: a radiation-free ultrasound showing the heart's chambers, pumping strength and all four valves in real time. It finds the silent structural problems - early valve disease, cardiomyopathy, the early stages of heart failure - that no blood test or ECG can see, and that benefit enormously from being monitored from an early stage.

The heart under load: exercise testing

Some problems only show themselves when the heart works hard. An exercise ECG or stress echocardiogram watches the heart under controlled exertion - valuable where risk is raised, symptoms are exertional, or you're returning to demanding sport. For performance-minded patients, VO2 max testing adds an objective fitness baseline (and, as we've written before, heart rate variability is a fascinating adjunct - though neither replaces the clinical tests above).

Advanced imaging - for when the question demands it

Where risk scores, symptoms or first-line results justify it, imaging answers the definitive question - what do the coronary arteries actually look like? A CT coronary angiogram visualises narrowings and plaque non-invasively; a cardiac MRI gives the gold-standard picture of heart muscle and structure. These are targeted tools, not default extras - a check that scans everyone regardless of risk is optimising for revenue, not health. (Our article on when an ECG isn't enough explains how imaging decisions are made.)

What a consultant-led check looks like in practice

At our Harley Street clinic, screening is staged rather than scattergun:

1. Consultation first - history, examination, family mapping and risk assessment with Dr Ravi Assomull.
2. Core tests the same visit - ECG, echocardiogram and bloods under one roof, in one appointment.
3. Advanced tests only where indicated - and explained before they're booked, with prices agreed in advance.
4. Results explained, in person and in writing - what was found, what it means for you, and a concrete prevention or treatment plan; a copy goes to your GP with your consent.

Structured packages (including the comprehensive Health MOT) are on the fees page, alongside the £325 initial consultation fee. For what the appointment itself feels like, see our step-by-step guide - and if you're weighing private screening against waiting for symptoms and the NHS route, our honest comparison covers the trade-offs. The NHS, by design, screens very little in symptom-free adults - prevention is where private cardiology adds the most unambiguous value.

Understanding your results

A good check ends with clarity, and results generally land in one of three places:

• All clear: the most common outcome - and not a wasted fee. You've converted "probably fine" into a documented baseline against which every future test gains meaning.
• Risk factors found: raised blood pressure, adverse cholesterol, elevated lipoprotein(a), pre-diabetes. This is screening's sweet spot: problems found before damage, fixable with medication and the lifestyle levers that genuinely work - exercise, diet and habits, sleep.
• A condition found: uncommon, and precisely the point. Silent AF, early valve disease or coronary narrowing found on screening is a condition found with every option still open - from medication through angioplasty or ablation - rather than announced by an ambulance.

How often should you re-check?

There is no universal answer - frequency should follow findings. As a rule of thumb: an all-clear result with low risk merits a review every few years; identified risk factors are typically reviewed annually so treatment stays on target; and any diagnosed condition follows its own surveillance schedule set by your consultant. What matters is that the interval is a clinical decision, not a subscription default. Life events reset the clock too: a new diagnosis in a close relative, a significant weight change, the menopause, or a return to hard training after years away are each sensible prompts to bring a review forward rather than wait for the calendar.

How to spot a good heart check (and a glossy one)

The private screening market is unregulated in its marketing, if not its medicine, and checks vary enormously. Five tests of quality that work anywhere:

• Who reviews the results? The gold standard is a consultant cardiologist who takes your history before testing and explains the results in person afterwards. A PDF emailed by a screening company - with "see your GP" appended to every abnormal line - outsources the only part that matters.
• Is test selection personal? A fixed menu applied to every customer is a business model, not medicine. Your family history, risk factors and symptoms should visibly change what is recommended.
• Does it include an echocardiogram? Structural disease is invisible to blood tests and often to the ECG; a "heart check" without imaging has a blind spot the size of a valve.
• Are prices itemised in advance? Screening should never generate surprise invoices - every test priced and agreed before it happens.
• What happens if something is found? The right answer is a concrete pathway: the same consultant explains it, arranges the next test or treatment, and writes to your GP. The wrong answer is a leaflet.

Red flags that mean "assessment now", not "screening later"

Screening is for the symptom-free. If any of these apply, you need a diagnostic appointment - promptly - rather than a wellness check:

• Chest pain, tightness or pressure - especially on exertion
• New or worsening breathlessness out of proportion to effort
• Palpitations that are prolonged, fast and chaotic, or exertional
• Fainting or near-blackouts, particularly during exercise
• New ankle swelling with fatigue or breathlessness

And crushing central chest pain now means 999 now - no clinic, no queue, no exceptions. For everything else on that list, our guide to when to see a cardiologist explains what each symptom may mean; the practical difference from screening is urgency and test sequence, and the appointment to book is the same initial assessment - typically available the next working day.

What the day itself feels like

For the avoidance of white-coat dread: a heart check is one of medicine's gentler experiences. Nothing hurts. You'll spend the first half-hour talking - family history, lifestyle, the symptoms you've been discounting - followed by an examination and blood pressure readings. The ECG is ten sticky electrodes and five quiet minutes lying still. The echocardiogram is the same technology used in pregnancy scans: gel, a probe on the chest, and thirty minutes watching your own heart beat on screen (most patients find it unexpectedly moving). Bloods are a standard draw. You'll be in and out in roughly two hours, having done nothing more strenuous than answer questions honestly - wear a top that's easy to remove, skip the pre-appointment espresso if palpitations are on your list, and bring reading glasses if you use them, because you'll want to see the images when they're explained. Results conversation included; jargon translated on request. Full detail in our step-by-step appointment guide.

Frequently asked questions

What does a private heart health check include?

At minimum: consultant consultation, properly measured blood pressure, advanced blood panel (including lipoprotein(a) where appropriate), a resting ECG, and - in any comprehensive check - an echocardiogram. Exercise testing and CT or MRI imaging are added where your risk profile justifies them, not by default.

How much does a heart check cost in London?

Our initial consultation is £325, with tests itemised and quoted before they're done; packages, including the full Health MOT, are listed on the fees page with instalment options. Our guide to private cardiologist costs breaks down insurance and self-pay in detail.

I feel completely fine - is a check really worth it?

Feeling fine is exactly the state in which screening is informative: blood pressure, cholesterol, lipoprotein(a), early valve disease and silent AF are all symptom-free by nature. Whether it's worth it for you depends on age, family history and risk factors - the honest answer comes from the risk assessment itself, and a low-risk result buys years of justified reassurance.

Do I need a GP referral for a heart check?

No - book directly. Appointments are typically available the next working day, with everything done under one roof at 68 Harley Street. If you're using insurance, note that most insurers cover investigation of symptoms rather than pure screening - check your policy; self-pay is the usual route for screening.

ECG or echocardiogram - which do I actually need?

They answer different questions: the ECG checks the electrics, the echocardiogram checks the structure. A check containing only an ECG can miss significant valve and muscle disease entirely - which is why comprehensive screening includes both.

The bottom line

You service your car on schedule and your boiler annually; your heart - the only genuinely irreplaceable machine you own - deserves at least one proper, consultant-led inspection before it forces the issue. Screening done well is calm, staged and personal: the right tests for your risk, explained by the person who chose them.
