At a Glance: NHS Health Check vs Private Health Screening
An NHS health check is a free preventive assessment offered to adults in England aged 40–74 every five years, designed to evaluate cardiovascular risk factors. A private health screening is an elective set of blood tests and health assessments that individuals can book at any time, without a referral, to gain a broader or more timely picture of their current wellbeing. Understanding the differences between these two options can help you make a more informed decision about when and how to monitor your health.
If you’ve recently received an NHS health check invitation—or you’re still waiting for one—you may be wondering whether it’s worth booking a private health screening in the meantime. It’s a question we hear frequently at our London-based clinic, and the answer depends on your personal circumstances, your age, your health history, and how proactive you’d like to be about understanding your body.
This guide compares both pathways in detail, helping you decide what’s right for you.
How Does the NHS Health Check Work?
The NHS Health Check programme is available to adults in England aged 40 to 74 who have not already been diagnosed with certain pre-existing conditions such as heart disease, diabetes, kidney disease, or stroke. It’s typically offered once every five years through your registered GP surgery.
During the check, a healthcare professional will usually assess:
- Blood pressure
- Cholesterol levels (total cholesterol and HDL)
- Blood sugar levels (to assess type 2 diabetes risk)
- Body mass index (BMI)
- Lifestyle factors such as smoking, alcohol intake, and physical activity
The results are used to calculate a cardiovascular risk score, which estimates your likelihood of developing heart disease or stroke within the next ten years.
Practical Insight: The NHS Health Check is an excellent baseline assessment, but its scope is intentionally focused on cardiovascular risk. It may not cover other areas of health that some individuals wish to explore.
What Does a Private Health Screening Typically Include?
A private health screening offers a wider panel of blood tests and health markers, depending on the package you choose. For a full breakdown of what to expect financially, see our complete guide to full body screening costs in the UK. Rather than focusing solely on cardiovascular risk, private screenings can provide insight into a broader range of biomarkers.
Common markers included in private health screening blood tests may cover:
- Full blood count (FBC) – evaluates red blood cells, white blood cells, and platelets
- Liver function tests (LFTs) – including ALT, AST, ALP, bilirubin, and albumin
- Kidney function markers – such as creatinine, urea, and eGFR
- Thyroid function – TSH and free T4
- HbA1c – a longer-term indicator of blood sugar management
- Lipid profile – total cholesterol, HDL, LDL, and triglycerides
- Iron studies – ferritin, serum iron, TIBC
- Vitamin D and B12 levels
- Inflammatory markers – such as ESR
At Health Screening Clinic, we are a nurse-led service providing testing and reporting only. We do not offer prescriptions, treatment, or GP services. Our role is to deliver clear, accurate results so you can share them with your own healthcare provider if needed.
Practical Insight: A broader blood panel can sometimes highlight areas that may benefit from further discussion with your GP—such as borderline thyroid results or low vitamin D—which a standard NHS Health Check would not typically assess.
NHS Health Check vs Private Screening: A Side-by-Side Comparison
| Feature | NHS Health Check | Private Health Screening |
|---|---|---|
| Cost | Free | Paid (varies by package) |
| Eligibility | Ages 40–74, no pre-existing conditions | Anyone, any age |
| Frequency | Every 5 years | As often as you choose |
| Waiting time | May wait weeks or months for an invitation | Book at your convenience |
| Scope | Cardiovascular risk focused | Broader range of biomarkers |
| Referral needed | No (invited by GP surgery) | No referral required |
| Results turnaround | Discussed at appointment or follow-up | Typically within a few working days |
| Blood markers tested | Cholesterol, blood sugar, BMI | Can include 30+ markers |
| Location | GP surgery or pharmacy | Private clinic (e.g., Central London) |
| Follow-up care | Via your GP | Results shared; follow-up with your own GP |
Practical Insight: Neither option is inherently better than the other. They serve different purposes and can complement each other effectively as part of a long-term approach to wellbeing.
Who Should Consider Booking a Private Health Screening?
While the NHS Health Check is a valuable service, there are circumstances where individuals may wish to explore private screening sooner or more frequently. You might consider a private screening if:
- You’re under 40 and not yet eligible for an NHS Health Check but want baseline health data
- You have a family history of conditions such as diabetes, heart disease, thyroid disorders, or high cholesterol
- You’re experiencing general symptoms such as persistent tiredness, unexplained weight changes, or low energy and want to understand your blood markers before seeking medical advice
- You haven’t received your NHS Health Check invitation and would prefer not to wait
- You’d like a broader panel of tests beyond what the NHS check covers
- You want to track your health over time, perhaps annually, rather than every five years
- You’re a Londoner with a busy schedule and want to book at a time that suits you without navigating GP appointment availability
Our clinic welcomes individuals from across London and the surrounding areas who simply want a clearer understanding of their current health markers.

You can explore the health screening packages available on our website for full details of what’s included.
How Often Should You Have a Health Screening?
The NHS recommends a health check every five years for eligible adults. However, many health professionals suggest that annual or biannual blood testing can be a more proactive approach, particularly for those with risk factors or a desire to monitor trends over time.
Regular screening can help you:
- Establish personal baselines – knowing what’s normal for you
- Identify gradual changes – such as slowly rising cholesterol or declining vitamin D
- Have informed conversations with your GP based on objective data
- Stay motivated with lifestyle changes by tracking measurable progress
There’s no single answer for everyone. Your ideal frequency may depend on your age, health history, lifestyle, and personal preferences. For a detailed age-based frequency guide, read our article on how often you should get a health check-up in the UK.
Practical Insight: Some individuals find that having an annual private screening between their five-yearly NHS checks provides a more complete picture of their health over time.
Understanding Your Results: What Do the Numbers Mean?
When you receive your screening results, each biomarker will typically be reported alongside a reference range. Here’s a brief overview of some commonly tested markers and what they can suggest:
- Total Cholesterol (< 5 mmol/L desirable): Elevated levels may be associated with increased cardiovascular risk. A full lipid profile including LDL and HDL provides more context.
- HbA1c (< 42 mmol/mol normal): This reflects average blood sugar levels over the past 2–3 months. Results between 42 and 47 mmol/mol may sometimes indicate a pre-diabetic range.
- TSH (0.27–4.2 mIU/L typical range): Thyroid-stimulating hormone levels outside this range can suggest the thyroid may not be functioning optimally.
- Ferritin: Low levels may be associated with iron deficiency, while high levels can sometimes highlight inflammation or other underlying factors.
- Vitamin D (> 50 nmol/L generally considered adequate): Many people in the UK, particularly in London during winter months, may have lower-than-optimal vitamin D levels.
- ESR (Erythrocyte Sedimentation Rate): An elevated ESR can sometimes indicate inflammation in the body, though it is a non-specific marker.
It’s important to remember that a single result outside the reference range does not necessarily indicate a medical condition. Results should always be considered in the context of your overall health and discussed with an appropriate healthcare professional.

Practical Insight: Understanding your results empowers you to have more productive conversations with your GP or healthcare provider, particularly if you’re considering lifestyle adjustments.
Why London Residents Are Choosing Private Health Screening
London’s fast-paced lifestyle means that many residents find it challenging to access timely GP appointments or wait for NHS screening invitations. Private health screening offers a flexible alternative that fits around busy schedules.
Additionally, London’s diverse population means that certain health risks may be more prevalent in specific communities. For example, individuals of South Asian, African, or Caribbean heritage may have a higher predisposition to type 2 diabetes or cardiovascular conditions, making earlier or more frequent screening a practical consideration.
Our nurse-led clinic in London provides a straightforward, accessible service. There are no referrals needed, and appointments can be booked directly through our website. We focus entirely on health screening and blood testing—providing you with clear, accurate results that you can take to your own healthcare provider.
Frequently Asked Questions
1. Should I wait for my NHS health check or book a private screening?
It depends on your individual circumstances. If you’re eligible and your NHS Health Check is imminent, it’s a valuable free service. However, if you’re not yet eligible, prefer a broader range of tests, or don’t want to wait, a private health screening can offer timely insight into your current wellbeing. Both options can complement each other.
2. What is included in a private health screening that isn’t in an NHS Health Check?
A private health screening may include a wider panel of biomarkers such as thyroid function, liver function, kidney function, iron studies, vitamin D, vitamin B12, and inflammatory markers. The NHS Health Check primarily focuses on cardiovascular risk factors including cholesterol, blood pressure, blood sugar, and BMI.
3. Can I have both an NHS Health Check and a private screening?
Yes, absolutely. Many individuals use private health screening to fill the gaps between their five-yearly NHS checks, or to obtain a more comprehensive view of their health. The two approaches are complementary, and your GP can use results from both when advising you.
4. How often should I have a private health screening?
There is no mandatory frequency, but many individuals opt for annual or biannual screening. If you have specific risk factors—such as a family history of diabetes or heart disease—more regular monitoring may be something to discuss with your healthcare provider.
5. Do I need a GP referral to book a private health screening?
No. At our nurse-led clinic, you can book directly without a referral. We provide testing and clear reporting of your results. If any results require further investigation, we always recommend discussing them with your GP or appropriate healthcare service.
6. What happens if my private screening results are abnormal?
If any of your results fall outside the normal reference range, we recommend sharing them with your GP or seeking appropriate medical advice. Our reports are designed to be clear and easy to understand, so you can have an informed discussion with your healthcare provider.
7. Is a private health screening suitable for people under 40?
Yes. While the NHS Health Check is only available to those aged 40–74, private screening is available to adults of any age. Younger adults who want to establish baseline health markers or who have a family history of certain conditions often find private screening helpful.
8. Are private health screening results reliable?
Private health screening blood tests are processed by accredited laboratories using the same analytical methods as NHS pathology services. Results are clinically reliable and can be shared with your GP as part of your ongoing health record.
9. How long does it take to get results from a private health screening?
At our clinic, results are typically available within a few working days. This is often faster than NHS pathways, where results may take longer depending on GP surgery processes and follow-up appointment availability.
10. Can a private screening diagnose a medical condition?
A private health screening provides data on your biomarkers and health indicators. It is not a diagnostic service. If results suggest areas that may need further investigation, we always recommend seeking medical advice from your GP or an appropriate healthcare professional. Our clinic provides testing and reporting only.
Taking a Proactive Approach to Your Health
Whether you choose to wait for your NHS Health Check, book a private health screening, or combine both approaches, the most important step is staying informed about your health. Knowledge of your biomarkers and risk factors empowers you to make better decisions and have more meaningful conversations with your healthcare provider.
At Health Screening Clinic, we believe in accessible, straightforward health testing. As a nurse-led clinic in London, we provide screening and reporting in a professional, supportive environment—giving you the information you need to take the next step on your own terms.
