The grant, which comes from the Masonic Charitable Foundation, is funded by Freemasons and their families across England and Wales.
A cheque presentation was held at the charity’s Redhill base, followed by a presentation from Director of Operations, Leigh Curtis, about how their continuing support has made such a difference.
The life-saving charity operates throughout the South East covering an area of 3,500 square miles and a population of 4.5million people. So far this year, their crews have been called to more than 600 missions, helping the most critically ill and injured people in the region.
During 2017, Freemasons around the country will be presenting 20 regional air ambulance charities with grants totalling £180,000.
Lynne Harris, Director of Income Generation for the charity, said: 'We are so grateful to Surrey Freemasons for their continuing generosity. Without support like this, we simply would not be able to continue our life-saving work.'
David Olliver, Provincial Grand Charity Steward of Surrey Freemasons, said: 'We are so pleased to continue supporting the great work of the Kent, Surrey and Sussex Air Ambulance. Supporting the work they carry out in our communities every day is something to be proud of.'
