It costs approximately £10 million a year to run our service, ensuring advanced trauma care can be provided to critically injured people in London, 24 hours a day, 7 days a week. We are a UK registered charity and rely on voluntary support, from trusts and foundations, companies, community groups and individuals to continue saving lives.

We are incredibly humbled to have so many passionate, dedicated and generous supporters helping to make our work possible. We want to inspire more people to support us regularly; both face to face and telephone fundraising give us the opportunity to talk directly to people, to let them know about our work and how they can be part of it. 

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.     

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.
