A health MOT—or executive health screening—is a comprehensive health review that checks your baseline status before problems develop. Unlike screening for one condition, it creates a detailed picture of your current health and risk factors.
What a health MOT actually includes
Proper health MOT covers cardiovascular risk, cancer screening, metabolic health (blood sugar and cholesterol), liver and kidney function, bone density, respiratory function, and mental health. It includes blood work, imaging, physiological measurements, and risk assessment.
The scope matters enormously. A basic MOT might only check cholesterol and blood pressure. A comprehensive one adds lipid subfractions, inflammatory markers (hs-CRP), liver enzymes, kidney function, thyroid status, glucose and insulin levels, bone density scan, ECG or stress testing, and often imaging like a carotid ultrasound or coronary calcium score.
In the UK, you can get basic screening through your NHS GP fairly easily. Private health MOTs go deeper but cost £800-3,000 depending on what's included. The difference is access to imaging, time, and specialist interpretation.
Which screening tests actually matter
Cardiovascular screening is the priority. Your heart is likely to kill you before other systems do. A standard lipid panel is baseline, but lipoprotein(a) and particle size matter more than total cholesterol for actual risk. A coronary calcium score (CT scan) gives you real risk data: a score of 0 means very low 10-year risk regardless of your cholesterol.
Cancer screening depends on age and sex. Bowel cancer screening (FOBT or colonoscopy) should start at 45-50. Prostate screening (PSA blood test) is controversial but a single baseline is reasonable at 40-45 if your family history is positive. Cervical screening (HPV testing) is covered by NHS if you're eligible. Lung screening only makes sense if you're a current or recent smoker.
Metabolic screening picks up prediabetes early. Fasting glucose alone misses many cases—insulin levels or a glucose tolerance test is more sensitive. Liver and kidney function are basic hygiene. A full blood count catches anaemia and infection patterns.
The MOT results: what's actually actionable
A good MOT doesn't just give you numbers—it tells you what to do with them. A calcium score of 50 means something different at age 40 versus 65. A cholesterol of 5.5 mmol/L is fine if your HDL is high, but concerning if it's mostly LDL with no HDL buffer.
The problem with many private MOTs is they create alarm without proportionality. You get handed results with red flags for borderline values that don't actually change management. This leads to unnecessary follow-up appointments and anxiety.
Ask upfront: What will you do differently based on each result? If the answer is "nothing changes," you're paying for reassurance, not information. That's sometimes worth it, but be clear on the cost-benefit.
How often should you repeat it?
A baseline MOT is useful. Repeating it every 1-2 years is excessive for most people. Annual monitoring makes sense if you have modifiable risk factors (smoking, high BP, prediabetes). If your baseline is clean and you're maintaining good habits, every 3-5 years is reasonable.
Targeted screening between MOTs is more efficient: annual blood pressure checks, fasting lipid panels every 5 years, diabetes screening if you've gained weight, cancer screening per NICE guidelines by age.
NHS vs private health MOT
The NHS does offer free health checks at age 40-74 (every 5 years if negative). These cover basic risk factors. They're underfunded and often rushed, but they're evidence-based and free.
Private MOTs offer more time, more tests, and usually more specialised interpretation. Whether that translates to better outcomes depends on your baseline risk. If you're at genuinely high risk, specialist input is valuable. If you're low-risk and just want reassurance, the NHS offering is adequate.
The best approach: Get your NHS health check to establish baseline. If results suggest risk, then consider private specialist review of the concerning areas. Don't pay £2,000 for comprehensive imaging if you're 35 and asymptomatic with no family history.
