About Calon Hearts
Cardiac arrest has no boundaries. Calon Heart Screening and Defibrillators is an award-winning charity founded by Sharon Owen in 2013 to help promote heart health throughout the country. Our passion to save lives has had a positive impact on communities, and we are excited to now take our lifesaving work of screening people for life-threatening heart conditions, placing defibrillators, and teaching CPR all across the UK.
Who We Are
We are a Wales-based charity working to prevent sudden cardiac death through early detection, access to life-saving equipment and practical training.
Our work supports individuals, families, schools, communities and organisations across the UK.
What We Do
We make it easier for people and communities to take action to protect heart health and respond in an emergency.
We deliver heart screening across the country to help identify undiagnosed conditions that may not show symptoms. Screening provides individuals with information about their heart health and, where appropriate, signposts them for further medical advice.
We support communities, organisations and workplaces to access defibrillators and keep them ready for use. This includes guidance on obtaining a device, where to place it and how to maintain it.
We provide CPR and first aid training to help people recognise cardiac arrest and respond quickly and confidently in an emergency.
Many heart conditions show no symptoms until a serious event occurs. We work to prevent avoidable deaths by making screening, defibrillators and lifesaving training more accessible.

Our Vision
Every week in the UK, 12 seemingly fit and healthy young people die from undiagnosed heart conditions which could have been detected through a simple screening. Our vision is to create a future where nobody in the UK dies prematurely from an undiagnosed heart condition. We can only achieve this with your support.
Our Mission
Why We Exist
We were founded following personal experience of heart disease and loss within a family.
That experience continues to shape everything we do, with a clear focus on early detection, prevention and giving people the tools and confidence to save lives.
How We Work
We work in partnership with communities, schools, workplaces, healthcare professionals and supporters to deliver practical, accessible heart health initiatives.
Support Our Work
Every screening session, training course and defibrillator placement is made possible through support from individuals, organisations and communities.
