The charity wants to buy its second helicopter rather than lease it which it says will save half a million pounds annually.

The air ambulance serves Kent, Surrey and Sussex and the aim is to get it in the air for six more hours every day.

As part of the Buy it for Life appeal, supporters are also being given the opportunity to have their name on the helicopter.

This is the first time this has been done and is open to those donating £100 or more.

David Welch, our Chief Executive, said: “Demand for our service has been growing year-on-year and has never been greater. Last year we made a record number of over 3,300 missions to people in urgent need of our lifesaving care. We must continue to respond to this growing need, now and into the future.

“That’s why we now urgently need the people of Kent, Surrey and Sussex, to help us raise the final £1 million to buy our air ambulance. Owning rather than leasing our air ambulance will secure the future of our helicopter and allow us to increase the number of hours we can fly every day, as well as continue to improve and innovate our lifesaving care. This will mean that we can reach even more patients and save even more lives. But we only have until the end of May to raise the funds as it is a time-limited window in our new contract with our aviation partner.

“For your community. For your family. For your friends. Please help buy our air ambulance helicopter so that when the worst happens, we can keep even more families and loved ones together.”
