The charity Air Ambulance NI works in partnership with the Northern Ireland Ambulance Service to provide the Helicopter Emergency Medical Service (HEMS). The service delivers urgent pre-hospital care directly to people who are critically ill or injured on average twice per day.

The life-saving service requires £5,500 each day in fundraising, so public donations are crucial. Any money you raise will help to save lives, brains and limbs!
