Restart a Heart

Restart a Heart returns this October 2025! Learn CPR, act fast, save lives.

Restart a Heart (RSAH) is an annual initiative led by Resuscitation Council UK which aims to increase the number of people surviving out-of-hospital cardiac arrests by helping more people learn CPR.

Find out how you can support our Restart a Heart campaign, watch videos, download resources, and more on this page.

Survival rates from out-of-hospital cardiac arrest remain stubbornly low in the UK, with fewer than one in 10 people surviving. 

What is Restart a Heart?

Every October an alliance of partners all over the world (including UK Ambulance Services, universities, and other charitable and public sector community-based organisations and first aid training organisations) come together to increase public awareness of cardiac arrests and the number of people trained in lifesaving CPR and defibrillation.

We do this by organising and facilitating training events and by providing opportunities for people to learn CPR and defibrillation digitally in the safety and comfort of their own homes.

You can expect to see Restart a Heart events happening throughout October, and on Restart a Heart day on 16 October. Restart a Heart encourages everyone to become ready for the ultimate medical emergency by learning the steps to CPR and how to use a defib.

Whether you're hosting an event or attending one, teaching in person or learning online, you have a key role to play in improving survival rates from out-of-hospital cardiac arrest. You can ensure that everyone has a chance to learn CPR and how to use a defib and that those having a sudden cardiac arrest have their best chance of surviving.

Why you should learn CPR

• Cardiac arrest occurs when the heart stops pumping blood around the body, and causes a person to collapse and stop breathing normally.
• Survival rates from out-of-hospital cardiac arrest remain stubbornly low in the UK, with fewer than one in ten people surviving. If CPR were more widely taught, thousands of lives could be saved every year. (Resuscitation to Recovery)  
• Around 80% of cardiac arrests happen in the home. Learning CPR guarantees that you have the skills to help those around you, including in the home. 
• Every second counts when having a cardiac arrest. It’s not fair that who you are, where you're from or your socio-economic background could affect whether you survive.
