Full Private Health Check in the UK: What’s Included

Written by Dr. Simon Khela MBChB MRCGP, GMC Registered Doctor

_________________________________________________________________________

A question I’m asked constantly, usually by patients who’ve seen an advert or a colleague’s recommendation, is deceptively simple: what actually happens at a private health check? The honest answer is that it varies enormously between providers, and the marketing around these packages doesn’t always make that clear. Some so-called “comprehensive” checks are little more than a blood test and a chat; others genuinely cover a wide range of physical measurements, blood work, and screening relevant to your age and sex.

This article sets out what a properly put-together full health check typically includes, how it compares with what the NHS already offers for free, and, just as importantly, what it can’t tell you. A good health check has real value. It isn’t, and shouldn’t be sold as, a guarantee that nothing is wrong.

Quick Answer: What’s Usually Included

A genuinely comprehensive private health check typically includes:

• A consultation covering your medical history, family history, lifestyle and any symptoms
• Physical measurements: blood pressure, resting heart rate, height, weight and BMI
• A blood panel covering full blood count, kidney and liver function, cholesterol (lipid profile), blood glucose or HbA1c, and thyroid function, often with additional markers depending on the package
• A urine test (urinalysis)
• An ECG to check your heart’s electrical activity
• Age and sex-appropriate screening components, such as a cervical smear, prostate-specific antigen (PSA) test, or discussion of breast or bowel screening
• A results consultation with a doctor, including a personalised action plan

What’s not usually included unless you specifically pay for it as an add-on: whole-body MRI, genetic testing, and advanced tumour marker panels, all covered in more detail below.

Why People Choose a Private Health Check

In England, the NHS Health Check already offers a free assessment every 5 years for adults aged 40 to 74 who don’t already have cardiovascular disease, diabetes, or related conditions, covering blood pressure, cholesterol, BMI and blood glucose. It’s a genuinely good, evidence-based programme. It’s also narrower in scope than most people assume, since it’s specifically designed to catch cardiovascular risk factors, not to act as a general check of overall health.

Private health checks tend to appeal to people who fall outside that age bracket, want a broader range of tests than the cardiovascular focus of the NHS programme, prefer not to wait for their next scheduled check, or simply want the reassurance of a same-day, unhurried appointment rather than a 20-minute nurse-led review.

The Core Components of a Full Private Health Check

Here’s what each part is actually looking for, and why it’s included:

• Consultation and history: covers your symptoms, family history, medications, smoking and alcohol use, and lifestyle factors, which shapes which additional tests are actually relevant to you rather than applying a blanket panel to everyone.
• Physical examination: blood pressure, resting pulse, height, weight and BMI, sometimes waist circumference, which together give a quick picture of cardiovascular and metabolic risk.

Blood tests: typically a full blood count (checking for anaemia or infection), kidney function (U&Es), liver function tests, a lipid profile measuring cholesterol, HbA1c or fasting glucose for diabetes risk, and thyroid function. Many packages also include vitamin D, B12, ferritin, and, for men, a PSA test, though PSA testing is something I always discuss individually given its genuine limitations around false positives.

• Urinalysis: a simple dipstick test that can pick up early signs of kidney problems, diabetes, or urinary infection.
• ECG: a brief recording of your heart’s electrical activity, useful for detecting rhythm abnormalities, though it won’t reliably detect narrowed arteries on its own.

Age and sex-specific screening: this might include a private cervical smear test for women in the relevant age range, discussion of breast or bowel screening eligibility, or a prostate discussion for men, aligned as closely as possible with what the national screening programmes already recommend rather than duplicating or replacing them unnecessarily.

• Results consultation: arguably the most important part. A good health check ends with a doctor talking you through what your results actually mean, not just a printout of numbers with reference ranges.
• Optional extras sometimes bundled in: vision and hearing screening, a basic lung function (spirometry) test, or body composition analysis, which can be useful additions depending on your occupation, age, or specific concerns, though they’re not universally necessary.

What’s Usually NOT Included Unless You Add It

Some genuinely useful-sounding tests are marketed as add-ons precisely because they’re not appropriate for everyone as standard, and it’s worth understanding why:

• Whole-body MRI: sounds thorough, but it frequently picks up incidental findings of uncertain significance, which can lead to unnecessary anxiety and further investigation without a clear benefit for most people without symptoms or risk factors.
• Extensive genetic screening: can be genuinely valuable for specific, targeted questions, such as a strong family history of a particular condition, but is a poor fit as a blanket addition to a general check.
• Broad tumour marker panels: markers like CA-125 or CA-19-9 have real uses in monitoring known cancers, but perform poorly as screening tools in people without symptoms, generating false positives more often than genuine early detection.
• DEXA bone density scans: useful for specific risk groups, such as postmenopausal women or those with risk factors for osteoporosis, but not something everyone needs as a default.

Choosing the Right Level of Check for You

A genuinely useful health check isn’t one-size-fits-all. What’s actually relevant depends on:

• Your age and sex, which determine which cancer screening components are relevant and which are not yet, or no longer, appropriate.
• Your family history, particularly of heart disease, diabetes, or specific cancers, which can justify additional or earlier testing.
• Your existing risk factors, such as smoking, high blood pressure, or being significantly overweight.
• Whether you have any current symptoms, in which case a health check isn’t the right tool at all; symptoms warrant a proper clinical assessment, not a screening package.

If you’re currently experiencing symptoms rather than looking for reassurance about your general health, booking a private GP appointment is the more appropriate route than a health check package, since screening tools are designed for people without symptoms, and a symptomatic problem needs to be properly worked up rather than screened for.

As a rough illustration: a fit and well 35-year-old with no family history and no symptoms is usually better served by a focused, lower-cost check than the most extensive package on offer. A 55-year-old with a family history of heart disease, a sedentary job and borderline blood pressure at their last check is a much stronger candidate for a comprehensive panel, simply because more of the additional tests are actually likely to be relevant to them.

The Limitations of Health Screening (Worth Knowing Before You Book)

I think it’s important to be candid here, particularly given my own professional background. The Royal College of General Practitioners has publicly raised concerns about non-evidence-based private screening, warning that tests offered outside the established national screening programmes can generate results of little or no value, and sometimes cause unnecessary worry rather than genuine reassurance.

This isn’t a reason to dismiss health checks altogether, but it is a reason to be realistic about what they can and can’t do. The UK National Screening Committee’s own principles exist precisely because testing healthy people isn’t automatically beneficial: tests can produce false positives that trigger unnecessary further investigation, false negatives that offer false reassurance, and incidental findings that were never the point of the test in the first place.

A well-designed health check, built around tests with a genuine evidence base and interpreted by someone who can put your results in context, is a reasonable and useful thing. A health check that runs every test imaginable regardless of relevance, sold on the promise of “catching everything,” is not automatically better, and can occasionally do more harm than good.

How Often Should You Have One?

There’s no single evidence-based answer that applies to everyone, which is itself worth knowing, since annual health checks are often marketed as an obvious default. In broad terms:

• If your last check was normal and you have no new symptoms or risk factors, every 1 to 2 years is a reasonable interval for most adults, rather than annually as a fixed rule.
• If you have known risk factors, such as a strong family history, or borderline results last time, more frequent review, guided by your doctor, makes sense.
• If you develop new symptoms at any point, that’s a reason to seek assessment promptly rather than waiting for your next scheduled check.

Common Myths and Misconceptions

• “A health check will catch everything.” No screening test, or combination of tests, can rule out every possible condition. A normal result reduces the likelihood of certain problems; it doesn’t guarantee good health.
• “More tests are always better.” As covered above, some additional tests mainly add the risk of false positives and unnecessary anxiety, rather than meaningful benefit, particularly in people without relevant symptoms or risk factors.
• “If I feel fine, there’s no point.” Several common risk factors, including high blood pressure, high cholesterol, and early diabetes, typically cause no symptoms at all, which is exactly why screening has value for the right people. However, in some cases, particularly when cholesterol levels are very high you can see symptoms of high cholesterol in your body.

• “Private health checks are more accurate than NHS tests.” The underlying tests and laboratory standards are generally the same; what private checks usually offer is convenience, speed, and broader scope, not a fundamentally more accurate result.
