Your local
life-saving charity

Essex & Herts Air Ambulance, unlike NHS emergency services, is a charity. The free life-saving service is provided 24/7 by helicopters and by rapid response vehicles.

Each critical care team consists of a pilot and co-pilot, a pre-hospital care doctor and a critical care paramedic.

They can be rushed to the scene with life-saving support equipment to deliver advanced clinical care, usually only available in the hospital emergency department.

Once stabilised, the patient will be conveyed to the most appropriate hospital by air or land.


It costs £12 million every year to cover all operational and charitable costs.

Without access to National Lottery funding and with only limited support from Government, we rely upon the generosity and goodwill of the people and businesses of Essex and Hertfordshire to remain operational and keep saving lives…we can’t fly without you!

Our Mission & How We’re Dispatched

We aim to save lives and reduce or prevent disability or suffering from critical illness and injury by delivering a first-class pre-hospital emergency medical service across Essex, Hertfordshire, and surrounding areas.

Our highly skilled and specially trained pre-hospital care doctors and critical care paramedics work alongside our regional partners using helicopters and rapid response vehicles fitted with state-of-the-art life-saving equipment. Our critical care teams are dispatched by the East of England Ambulance Service NHS Trust.

We are here to assist everyone who lives, works, or travels through the region. The charity provides the service free of charge to patients of all ages, from every background and faith, who require the most advanced clinical care.

Electrical charging points Electrical charging points

Electric vehicle charging points have been installed at both airbases and our headquarters in Earls Colne.

Additional steps such as improved waste segregation, recycling and eco boilers have been installed at both airbases and our headquarters in Earls Colne.

Reduce, Reuse, Recycle Reduce, Reuse, Recycle

Our charity shops provide a sustainable and ethical option when people wish to dispose of unwanted goods, promoting reuse and recycling to reduce landfill, which makes a positive difference to the UK’s carbon footprint.

Virtual Events Virtual Events

We regularly run virtual events, accelerating fundraising activity whilst delivering a greater ROI with a lower carbon footprint than large in-person events.

Cashless Donations Cashless Donations

We are introducing cashless donations alongside our traditional cash tins in shops, pubs, and other retail outlets. Over time, as we phase-in contactless and phase-out cash, this will mean less mileage to collect cash tins, and bring them back to our bases.

Hybrid working Hybrid working

In the charity as a whole, we are moving towards hybrid working with office staff spending 40% of their time working from home.



EHAAT, in conjunction with Carbon Footprint Ltd, has assessed its carbon footprint and has achieved a reduction of 21.2% from the baseline year, in absolute emissions, using the baseline scope.

North Weald airbase visitor centre room


Essex & Herts Air Ambulance have a Visitor Centre at both our airbases at Earls Colne and North Weald. Whether you are an individual interested in our work or a group looking at fundraising opportunities we have something for everyone, and we look forward to welcoming you.

North Weald Airbase

The building has been designed to current BREEAM ratings and has achieved an energy performance certificate (EPC) grading of A, the highest possible.

Photovoltaic panels on the roof at North Weald mean that the building generates electricity. Any excess is sold to National Grid.

Motion sensor lighting inside the building means lights are only active when most areas are occupied, reducing electricity consumption.

We’ve been operating from Earls Colne since 2011 and have continually improved the facilities. With the help of our remarkable supporters, we updated and extended our hangar to create a first-class facility, enabling us to continue to provide an exceptional clinical service for those in need across the region well into the future. We’ve also incorporated Photovoltaic panels to generate electricity with excess sold to National Grid. Earls Colne is also home to our headquarters and visitor centre (based at Earls Colne Business Park), where we regularly welcome and engage with our supporters, giving visitors an insight into the work of the charity, a guided tour of the visitor centre, plus the unique opportunity of seeing the helicopter and meeting the crew (subject to operations).

Continuous Improvement & Innovation

As part of our commitment to continuously raise the bar and deliver outstanding patient care, EHAAT introduced blood on board in 2019. On average, our critical care team treats approximately 60 patients in desperate need of a blood transfusion at the scene of an incident every year. By carrying bags of O-negative red blood cells, blood plasma, blood warmer and specialist coolboxes in the helicopters and rapid response vehicles (RRVs) our team provide extra care to patients suffering significant blood loss. Night flying is another huge step forward in our strategic aim of providing the highest possible standards of pre-hospital clinical care. The crew use night vision goggles (NVG), which are calibrated to meet the specific vision requirements of the individual and are attached to the front of the flight helmets. This allows our pilots to see obstructions clearly and land in areas that are unlit.
