Know your Numbers! Week 8 – 14 September 2025

Know Your Numbers! Week reaches those who have high blood pressure and don’t know it, so they can get the treatment and support they need to bring it under control.

Right now, 5 million UK adults aged 18-64 may have undiagnosed high blood pressure – increasing their risk of heart attack, stroke, and kidney disease. Many don’t even know it. That’s why getting a simple blood pressure check at home could literally be a lifesaver.

High blood pressure is known as the “silent killer” – no symptoms, just risk. But knowing your numbers gives you the power to act – whether that’s eating less salt, being more active, or starting medication if needed. Age doesn’t matter. Everyone should Know Their Numbers!

Encouraging adults to know their blood pressure numbers and take the necessary action to reach and maintain a healthy blood pressure.

1.5 million
1.5 million people have had a free blood pressure check during our annual Know Your Numbers! Week, the UK’s biggest blood pressure testing and awareness event.

120/80
An ideal blood pressure is under 120/80mmHg.

6 million
6 million people in the UK have high blood pressure and don’t know it.

350
Every day in the UK, 350 people have a stroke or heart attack that could have been prevented. 

We believe every adult in the UK should know their blood pressure numbers in the same way they know their height and weight. When you Know Your Numbers! you can take steps to look after your blood pressure and lead a long and healthy life. 

High blood pressure, also known as hypertension, is a global health challenge affecting millions.

Shockingly, approximately 5.5 million adults in England remain unaware that they have this condition. Even more concerning, high blood pressure is responsible for over half of all strokes and heart attacks, as highlighted in the January 2017 Health Matters report.
