When a heart stops, the most powerful response is not blue lights — it is a human being.

Every minute counts in cardiac arrest. By funding CPR training, public access defibrillators, and volunteers in local communities, we turn bystanders into London Lifesavers and give families more tomorrows.

Your support improves the healthcare and resilience of the communities we serve, enhances the wellbeing of the people of London Ambulance Service and celebrates the proud history of London's emergency healthcare services.
