- Health checks aren’t universally recommended — many medical bodies are sceptical of broad screening in healthy adults.
- For specific groups (over 40s, family history of disease, lifestyle risk factors, never-tested adults), a focused check has real value.
- A good health check is targeted, evidence-based, and starts with a conversation — not a list of every test that exists.
- Avoid “executive health check” packages that include scans you don’t need, run by clinics that profit from follow-up tests for incidental findings.
A real conversation about screening
The private health check market is enormous. Whole clinics exist to sell £500–£5000 packages of blood tests, scans, ECGs, and consultations. Some are genuinely useful. Others mostly produce anxiety and follow-up costs from incidental findings.
The honest medical position: broad screening of asymptomatic adults is more nuanced than “more tests = better.” The NHS, USPSTF, Cochrane reviews, and most national bodies are cautious about routine health checks — not because tests are inherently bad, but because every test has false-positive and false-negative rates, and untargeted testing in low-risk people produces more harm than benefit.
This doesn’t mean private health checks are useless. It means the right check, in the right person, at the right time can be very useful.
Who genuinely benefits
Adults over 40 who haven’t had recent blood tests
Around 40, the prevalence of detectable issues (high cholesterol, raised blood pressure, pre-diabetes, vitamin deficiencies) rises substantially. A baseline check has real value — partly to detect issues, partly to establish a starting point.
People with risk factors
- Family history of heart disease, stroke, diabetes, or cancer in first-degree relatives
- Personal lifestyle factors: smoking, significant alcohol use, sedentary work, overweight
- Working in stressful environments
- Long working hours, poor sleep, irregular eating patterns
People with non-specific symptoms
Persistent tiredness, vague digestive symptoms, mood changes, weight changes — in these cases, a focused check is more diagnostic workup than “screening,” but framed as a check.
People due for catch-up screening
If you’ve never had a smear test, never had blood pressure checked, never had cholesterol measured — a single comprehensive visit can address several things at once.
Who probably doesn’t need one
- Young, healthy adults with no symptoms or risk factors — very low yield
- People with no symptoms who’ve had a check in the last 1–2 years — diminishing returns
- People hoping to be reassured about a specific symptom — better to see a GP about the symptom directly
- People wanting cancer screening as a primary goal — broad health checks aren’t cancer screens
What a useful health check includes
A proper conversation first
History, family history, lifestyle, current symptoms, mental health, goals. This shapes what tests are worth doing.
Examination
Blood pressure (properly measured), pulse, heart and lung examination, weight and height with BMI, waist circumference.
Blood tests — focused
- Full blood count
- Kidney function
- Liver function
- Lipid profile (cholesterol, including HDL/LDL ratio)
- HbA1c (diabetes screening)
- Thyroid function
- Vitamin D
- Ferritin (iron stores)
- B12 (especially over 50 or vegetarian)
- Inflammatory marker (CRP)
Cancer screening relevant to your demographics
- Cervical screening (women)
- Discussion of bowel screening (FIT test) for over 50s
- Discussion of mammography for women over 50
- Discussion of PSA testing for men over 50 (or earlier if family history)
- Skin examination if multiple moles or skin cancer history
A written summary and clear plan
You should leave with: what was checked, what was found, what’s normal, what isn’t, what to do about each finding, when to repeat what. Not a stack of unexplained printouts.
Red flags — what to avoid
Whole-body scans without indication
Marketed as “peace of mind.” In reality, they find incidental findings in around half of patients — small cysts, benign lesions, harmless variants — that lead to follow-up scans, biopsies, and significant anxiety, mostly for nothing.
60+ marker blood panels
Sounds thorough. In practice, statistical artefact alone means several markers will flag as “abnormal” in healthy people. Each abnormal result generates follow-up; most are nothing.
Genetic testing without genetic counselling
Direct-to-consumer genetic tests have a high false-positive rate, often produce variants of uncertain significance, and need expert interpretation.
Heavy upsell to follow-up tests
If every result generates a recommendation to book the next package, treat with caution. Good clinical practice means accepting that some findings need watching, not investigating.
“Optimal” ranges
Some private services use tighter-than-standard reference ranges to label normal results as “suboptimal,” then sell supplements or follow-up. Be cautious. Reference ranges exist for a reason.
Vague reports
Avoid services that hand you a long PDF without a doctor explaining what it means. A health check without proper explanation isn’t a health check — it’s a data dump.
The overdiagnosis problem
Overdiagnosis is real and a major reason for medical caution about broad screening. The pattern: a test finds something (a small thyroid nodule, a tiny breast calcification, a small prostate elevation) that would never have caused symptoms or shortened life. But once found, it gets investigated — biopsies, follow-up scans, sometimes treatment. Each of these has its own risks.
A good private check minimises this by:
- Testing only what’s likely to change management
- Having clear plans before testing for what abnormal results would mean
- Being willing to say “this is probably nothing” rather than “let’s scan again in 6 months” for every minor finding
Alternatives worth considering
NHS Health Check (40–74)
Free, covers cardiovascular risk, diabetes screening, blood pressure, lifestyle review. Available every 5 years.
Targeted single-issue testing
If you have one specific concern, a focused 30-minute GP appointment about that issue is often more useful than a generic health check.
Cardiovascular risk assessment
For middle-aged adults, a proper cardiovascular risk calculation (QRISK score) combined with cholesterol, BP, and HbA1c is the highest-yield specific check.
Our approach
At MHW, we offer health checks that are:
- Conversation-led — we discuss your concerns and risk profile before deciding tests
- Evidence-based — we don’t add tests because they’re profitable or impressive-sounding
- Followed up properly — you get a written summary, an explanation, and a clear plan
- Honest — we’ll tell you when a test won’t help, even if you ask for it
See our Health MOT page for what we include and how it works.
Speak with us first about what you actually want to find out. We’ll recommend the right package for you — or tell you honestly if you don’t need one yet.
