Home | Calon Hearts

Our Work

We focus on three areas

Screening: identifying undiagnosed heart conditions early
Defibrillators: improving access to life-saving equipment
CPR And First Aid Training: The confidence to respond when every second counts
Training: giving people the skills and confidence to act

This work is delivered in partnership with communities, schools, workplaces and supporters across the country.

Three Ways To Take Action

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.

Screening available across the country
Free for ages 15½-26
Part-funded options available for ages 27+

Why This Matters

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.
