The NHS offers a range of free health checks and screening programmes that can detect serious conditions years before symptoms appear. Yet uptake remains lower than it should be — many UK adults either don't know these checks exist, don't realise they qualify, or haven't been proactively invited. This guide covers eight key NHS-delivered screenings and health checks that every adult should be aware of.
The Uptake Problem
NHS bowel cancer screening has an uptake rate of around 67% — meaning one in three eligible people who receive a test kit never return it. Breast cancer screening uptake is approximately 70% (NHS England data; rates vary by region). Early detection dramatically improves survival rates. Booking these free checks takes minutes and could save your life.
1. NHS Health Check (Age 40–74)
The NHS Health Check is a free check for adults aged 40–74 who are not already being treated for a relevant condition. It assesses risk of heart disease, stroke, diabetes, kidney disease, and dementia. Available every 5 years. Includes blood pressure, cholesterol, BMI, blood sugar test, and lifestyle assessment. Book through your GP surgery or local authority.
2. Bowel Cancer Screening (Age 50–74)
In England, NHS bowel cancer screening is offered to everyone aged 50–74 every two years. You receive a home test kit (FIT test) by post — a simple stool sample test. Bowel cancer is the second most common cause of cancer death in the UK; caught early, over 90% of cases are treatable (NHS guidance). Return your kit promptly when it arrives. If your result is abnormal, you'll be invited for a colonoscopy.
3. Breast Cancer Screening (Women 50–71)
Women aged 50–71 are invited for a free NHS mammogram every three years as part of the NHS Breast Screening Programme. The mammogram takes approximately 30 minutes. You will be invited automatically by your GP practice. Do not wait to be invited if you have symptoms — see your GP immediately if you notice any breast changes.
4. Cervical Cancer Screening (Women 25–64)
Cervical screening (the "smear test") is offered every 3 years for women aged 25–49, and every 5 years for women aged 50–64. The NHS Cervical Screening Programme uses HPV primary testing. You will be invited by letter. Book through your GP. Do not skip invitations — cervical cancer is largely preventable with regular screening.
5. Abdominal Aortic Aneurysm (AAA) Screening (Men aged 65)
All men in England are automatically invited for a one-off ultrasound scan for AAA when they turn 65. An abdominal aortic aneurysm is a potentially fatal bulge in the main blood vessel leading from the heart. The scan takes about 10 minutes and is painless. Women and men over 65 who may have missed the invitation can self-refer via their GP.
6. Diabetic Eye Screening (People with Diabetes)
Everyone with diabetes (Type 1, Type 2, or gestational) should be offered annual diabetic eye screening (retinal photography). Diabetic retinopathy is the leading cause of blindness in working-age adults in the UK — but is largely preventable with annual monitoring and treatment. You should be registered for this through your GP or diabetes care team.
| Screening | Who Qualifies | Frequency | How to Access |
|---|---|---|---|
| NHS Health Check | Age 40–74 (no known condition) | Every 5 years | GP or local authority |
| Bowel Cancer | Age 50–74 | Every 2 years | Home kit by post |
| Breast Cancer | Women 50–71 | Every 3 years | Invited by GP letter |
| Cervical Screening | Women 25–64 | 3–5 years | GP appointment |
| AAA Screening | Men at 65 | Once | Automatic invitation |
| Diabetic Eye Screen | People with diabetes | Annual | Through GP/diabetes team |
| Blood Pressure Check | Any adult | At least every 5 years | GP, pharmacy, or NHS Health Check |
| Cholesterol Test | Age 40+ or risk factors present | Every 5 years | GP or NHS Health Check |
7. Blood Pressure Check
High blood pressure (hypertension) affects around 1 in 4 UK adults — and half of those do not know they have it. It significantly raises risk of heart attack and stroke. All adults should have their blood pressure checked at least every 5 years; more frequently if you are at higher risk. Your GP will check it at any appointment, or you can use a self-service blood pressure machine at most pharmacies for free.
8. Cholesterol and Cardiovascular Risk
High cholesterol has no symptoms but significantly increases cardiovascular risk. A full lipid profile (total cholesterol, LDL, HDL, triglycerides) is included in the NHS Health Check for eligible adults. If you're aged 40+ and haven't had a check in 5+ years, request one from your GP. Those on statins require annual monitoring. The British Heart Foundation offers a free online Heart Age Calculator as a starting point.
Take Action Today
If you are aged 40–74 and haven't had an NHS Health Check recently, contact your GP surgery to book one. If you are overdue for cervical or breast screening, book your appointment directly through your GP. If you received a bowel screening kit and haven't returned it, do so now — it takes minutes and could detect cancer early. All of these screenings are free on the NHS.
