Complete Guide to Preventive Health Checkups in London
Everything you need to know about preventive health checkups in London — what they typically include, who should consider them, how often to screen, and how to interpret your results.
What Is a Preventive Health Checkup?
A preventive health checkup is a proactive health assessment designed to evaluate key biomarkers and health indicators before symptoms develop. It typically involves a series of blood tests and physiological measurements — such as blood pressure, cholesterol levels, blood glucose, liver function, and kidney function — that together provide a broad snapshot of your current health status.
Many individuals in London choose annual preventive health screening to establish a personal health baseline, making it easier to identify changes over time. For a detailed look at what a screening appointment involves, see our guide to what happens during a full-body MOT.
What Does a Preventive Health Checkup Include?

Depending on your risk profile, your checkup may also incorporate cardiovascular health screening tests, cholesterol testing, or cancer risk assessment biomarkers.
How Often Should You Have a Preventive Health Checkup?
- Ages 18–30: Every 2–3 years if no specific risk factors are present
- Ages 30–50: Annually or every 1–2 years
- Ages 50+: Annually, or as recommended by your healthcare provider
- Those with known risk factors: More frequent monitoring may be appropriate
The NHS Health Check is offered to adults aged 40–74 every five years. Many Londoners choose private health screening to supplement this with more frequent and comprehensive testing. For detailed frequency guidance, see how often you should get a health check-up in the UK.
