London’s Air Ambulance is a charity

We rely on public donations and fundraising

We work closely with the NHS and receive some funding from our NHS partners, but we are not an NHS organisation. The majority of our service’s running costs are funded by you; our supporters. Without your help, we cannot help our patients.

Where does our funding come from?

Our charity’s supporters are at the heart of our funding. From corporate partners and community groups, to event fundraisers and regular givers, we are lucky to have a dedicated supporter base helping our service.

Our NHS partners

London Ambulance Service employs and remunerates our charity’s paramedics, who typically join us for one-year secondments. 

Barts Health NHS Trust employs and remunerates the registrars, who typically join us for six month secondments, and the consultants who are permanently associated with the service. They also provide direct financial support in the form of a monthly grant and the helipad facilities at The Royal London Hospital required for our operations.

The regulatory requirements of the Care Quality Commission are covered by Barts Health and London Ambulance Service for all clinicians attached to the service.

How we spent our funding

It cost approximately £7.9 million (consolidated costs) to provide London with an advanced trauma care service 24 hour a day, 7 days a week (very close to the restated cost of providing the service last year). Over £4 million went towards funding our charitable activities, including approx. £3 million on operating and maintaining the helicopters. 

Do you carry out face to face fundraising?

We carry out face to face fundraising in privates sites, such as shopping centres, and also have fundraisers who go door to door. We encourage people to become regular supporters either by playing our weekly lottery, or by signing up to a monthly donation. These regular gifts are incredibly valuable to us as they provide sustainable and unrestricted income, which helps us plan and deliver the service we provide with a greater degree of confidence. Face to face fundraising is also a great way for us to raise awareness of our work out in the community.

Do you carry out telephone fundraising?

We use telephone fundraising to communicate with existing supporters; we never make cold calls. We call supporters to thank them for their donation and to find out if they would like to continue to support our life-saving work with a regular donation. Examples of our telephone fundraising campaigns are reaching out to people who supported with text donations following our Trauma Doctors TV documentary or contacting previous donors to give them the option of becoming regular supporters.

Who has called me?

We partner with Unity4 Ltd. to support our fundraising efforts. You may get a call from Unity4 on telephone number 020 4655 3401.

If Unity4 cannot get through to a supporter they will try again, but no more than once a day. We also work with Purity Fundraising, a telephone fundraising agency.

How can I tell if a London's Air Ambulance fundraiser is genuine?

We have an in-house team of face to face fundraisers and we also work with Wesser Fundraising, Tower Engage People and Gemini Fundraising, three specialist face to face agencies who help us carry out our fundraising. All our fundraisers carry photo ID. We have a copy of their photo along with the areas they cover, but you can also contact our office to confirm their identity.

How can I contact you if I have any questions or concerns?

We are committed to the highest standards of fundraising practice. Please read our fundraising promise for more information. All our fundraisers receive training from us and we regularly review our processes. However, if you ever have any questions or concerns about any of our fundraising, or would like to make a complaint, please contact us on or 020 3023 3319, we are available to take your call Mon-Fri from 9.00am-5.00pm.

Why do we use fundraising agencies?

Fundraising is a very difficult job, requiring lots of support, administration and training. Although we can support a small in-house team, in order to generate the level of support we need we have to look for external help. Each of our agencies are specialists in what they do and believe in our work here at London’s Air Ambulance Charity, allowing us to focus on other aspects of the charity whilst they take care of some of our fundraising needs. We ensure that each agency is carefully trained and monitored so that they are the best possible ambassadors for us.

Who are our fundraisers?


You’ll often find our in-house team in The Royal London Hospital, 17 floors below the helipad. When not there you can find them all around London: in hospitals, shops or your local GP’s surgery. Set up in June 2018, they generate brilliant support for the charity, and are still looking to grow – why not join them here?
