Calon Hearts UK
We work to identify undiagnosed heart conditions, place defibrillators in communities and train people to respond in an emergency. Whether you need a screening, want to protect your community or support our work, we’ll help you take the next step.
Our Work
This work is delivered in partnership with communities, schools, workplaces and supporters across the country.
Heart conditions can go undetected until it is too late. Our screening programme helps identify potential issues early, giving people the chance to take action.
Early access to a defibrillator can save a life. We support communities, organisations and workplaces to access and maintain this vital equipment.
Knowing what to do in an emergency can make all the difference. We provide training for communities, schools and workplaces to build confidence and skills.
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.
