What Is a QRISK Score?
A QRISK score NHS is a number — expressed as a percentage — that estimates your risk of developing cardiovascular disease (CVD) over the next 10 years. CVD includes heart attacks, strokes, and related conditions caused by narrowing or blockage of the arteries. It is the leading cause of premature death in the UK.
The QRISK score is calculated using an algorithm called QRISK3, developed by the University of Nottingham and EMIS Health. It is the tool recommended by NICE (National Institute for Health and Care Excellence) and used by NHS GPs across England to assess cardiovascular risk and guide treatment decisions — particularly whether to prescribe cholesterol-lowering medication (statins).
If you want to estimate your own QRISK3 score before or after reading this guide, use our free QRISK Calculator NHS — it gives you an approximate 10-year cardiovascular risk estimate based on your personal risk factors.
🫀 What does your QRISK score mean in plain English? A QRISK3 score of 15% means that approximately 15 in 100 people with your combination of risk factors would experience a heart attack or stroke in the next 10 years. The lower your score, the lower your risk.
QRISK3 Risk Levels — What Your Score Means
QRISK3 results are interpreted using three main risk categories. Here is what each level means and what the NHS recommends in 2026:
NHS does not routinely offer statins at this level. Focus on lifestyle and recheck in 5 years.
NICE recommends discussing statin therapy. Lifestyle changes strongly advised. Annual review.
NHS recommends high-intensity statin therapy + urgent lifestyle changes. GP review essential.
💊 NICE Statin Threshold (CG181): The NHS offers statin therapy (typically atorvastatin 20 mg) to all adults with a QRISK3 score of 10% or more. Statins are also offered regardless of QRISK score to people with existing CVD, type 1 diabetes, or chronic kidney disease (CKD stage 3+).
How Is the QRISK3 Score Calculated?
QRISK3 calculates your 10-year cardiovascular risk using a complex statistical model built from anonymised health records of millions of NHS patients. It combines your personal characteristics with known cardiovascular risk factors, each weighted according to their contribution to risk in the UK population.
The full clinical QRISK3 tool — used by your GP through their clinical software — draws automatically from your medical record, including:
- Multiple blood pressure readings — including variability over time
- Fasting cholesterol results — total cholesterol and HDL cholesterol ratio
- HbA1c — for diabetes diagnosis and control
- Serum creatinine — for kidney function (eGFR) and CKD staging
- Full medication list — antihypertensives, steroids, antipsychotics
- Complete medical history — including all QRISK3-relevant conditions
This is why our online QRISK Calculator NHS provides an estimate only — not a precise clinical score. For an accurate QRISK3 result, book an NHS Health Check with your GP surgery.
QRISK2 vs QRISK3 — What Changed?
QRISK3 was developed in 2017 and replaced QRISK2 as the NHS standard in 2018. The key improvement is the inclusion of additional risk factors that QRISK2 did not account for:
📋 QRISK2 (Superseded 2018)
- Age, sex, ethnicity
- Systolic blood pressure
- Total:HDL cholesterol ratio
- Body mass index (BMI)
- Smoking status
- Deprivation (Townsend score)
- Family history of CVD
- Diabetes (type 1 and type 2)
- Atrial fibrillation
- Rheumatoid arthritis
- Antihypertensive treatment
✅ QRISK3 (Current NHS Standard)
- All QRISK2 factors, PLUS:
- Systolic BP variability (multiple readings)
- Chronic kidney disease (CKD)
- Systemic lupus erythematosus (SLE)
- Severe mental illness
- Erectile dysfunction (men)
- Migraine
- Oral corticosteroid use
- Atypical antipsychotic use
- HIV/AIDS
- Contraceptive pill / HRT (women)
These additional variables make QRISK3 more accurate across a broader range of patients — particularly women on hormonal treatments, people with mental health conditions, and those with autoimmune diseases who were previously underestimated by QRISK2.
Key QRISK3 Risk Factors — What Has the Greatest Impact?
Not all risk factors contribute equally to your QRISK score. Understanding which factors have the highest impact helps you prioritise the changes most likely to reduce your score:
| Risk Factor | Modifiable? | Impact on Score |
|---|---|---|
| Age | Non-modifiable | Very High |
| Male sex | Non-modifiable | High |
| Heavy smoking | Modifiable | High |
| High systolic blood pressure | Modifiable | High |
| High total:HDL cholesterol ratio | Partly modifiable | High |
| Type 2 diabetes | Partly modifiable | High |
| Atrial fibrillation | Non-modifiable | High |
| BMI above 30 (obesity) | Modifiable | Moderate |
| South Asian / Pakistani ethnicity | Non-modifiable | Moderate |
| Deprivation (Townsend score) | Partly modifiable | Moderate |
| CKD stage 3+ | Non-modifiable | Moderate |
| Family history of CVD | Non-modifiable | Moderate |
| Corticosteroid use | Partly modifiable | Moderate |
| Alcohol intake above 21 units/week | Modifiable | Lower |
How to Reduce Your QRISK Score — NHS Guidance 2026
While some QRISK3 risk factors are fixed (age, sex, ethnicity, family history), many of the most impactful factors are fully or partly modifiable. Here are the NHS-recommended changes that have the greatest effect on your cardiovascular risk score:
Stop Smoking — The Single Biggest Change
Smoking is one of the most powerful modifiable risk factors in QRISK3. Stopping smoking within 3–5 years reduces cardiovascular risk to near that of a non-smoker. The NHS Smokefree helpline (0300 123 1044) offers free, expert support. Stopping smoking also benefits your blood pressure — check yours with our Blood Pressure Calculator NHS and read our blood pressure chart UK guide.
Lower Your Blood Pressure
Systolic blood pressure is one of the strongest continuous predictors in QRISK3. Every 10 mmHg reduction cuts CVD risk by 20–25%. Salt reduction, regular exercise, weight loss, limiting alcohol, and antihypertensive medication all contribute. Target below 130/80 mmHg for greatest cardiovascular benefit.
Achieve a Healthy Weight — BMI 18.5–24.9
Obesity contributes to cardiovascular risk through its effects on blood pressure, cholesterol, blood sugar, and inflammation. Losing even 5–10% of body weight meaningfully reduces CVD risk. Use our Visual BMI Calculator, NHS Healthy Weight Calculator, and Calorie Deficit Calculator NHS to plan your weight loss. See also: safe rate of weight loss per week and what is a calorie deficit.
Exercise 150+ Minutes Per Week
Regular aerobic exercise reduces blood pressure, improves cholesterol profile, reduces weight, and independently lowers cardiovascular risk. The NHS recommends at least 150 minutes of moderate-intensity activity weekly. Even brisk walking for 30 minutes five times per week meets this target and confers significant cardiovascular benefit.
Improve Your Diet and Cholesterol
Your total:HDL cholesterol ratio is a key QRISK3 input. To improve it: replace saturated fats with unsaturated fats (olive oil, nuts, oily fish); eat 5+ portions of fruit and vegetables daily; add soluble fibre (oats, lentils, beans); and limit red and processed meat. The Mediterranean diet has the strongest evidence for cardiovascular risk reduction. See our NHS vs CDC guidelines explained.

Frequently Asked Questions
A QRISK score NHS is a percentage estimating your 10-year risk of developing cardiovascular disease (CVD) — including heart attack or stroke. It is calculated using the QRISK3 algorithm, which combines personal, clinical, and lifestyle risk factors. A score of 10% means approximately 10 in 100 people with your profile would develop CVD in the next decade. Try our free QRISK Calculator NHS for an estimate.
A QRISK3 score below 10% is considered low risk — the NHS does not routinely offer statins at this level. A score of 10–20% is moderate risk — statins are discussed. A score above 20% is high risk — statins are strongly recommended alongside lifestyle changes. NICE CG181 sets 10% as the threshold for statin therapy in primary prevention.
QRISK3 (2017) replaced QRISK2 as the NHS standard in 2018. QRISK3 includes additional risk factors not captured by QRISK2: SLE, severe mental illness, systolic BP variability, corticosteroid use, erectile dysfunction, migraine, atypical antipsychotics, HIV, and HRT/contraceptive pill use. QRISK3 is more accurate across a broader range of patients, particularly those with complex health profiles.
According to NICE guideline CG181, NHS GPs offer statin therapy (typically atorvastatin 20 mg) to adults with a QRISK3 score of 10% or more. Statins are also offered regardless of QRISK3 score to people with established CVD, type 1 diabetes, or CKD stage 3+. Your GP will discuss your individual risk and circumstances before prescribing. Statins are one of the most evidence-based medications for primary cardiovascular prevention.
Yes — many QRISK3 risk factors are modifiable. The most impactful changes are: stopping smoking; reducing systolic blood pressure; losing excess weight (use our NHS Healthy Weight Calculator); improving cholesterol through diet; exercising 150+ min/week; and limiting alcohol. Medication (statins, antihypertensives) also reduces risk significantly. Even a 5 kg weight loss can reduce systolic BP by 4–5 mmHg, directly lowering your QRISK3 score. See our guide on the safe rate of weight loss per week.
