The Charities Aid Foundation has made £500,000 in Libor fine money available to support the training of search-and-rescue volunteers.
The UK Search and Rescue Volunteer Fund is open to all search-and-rescue organisations that are authorised to operate and provide 24-hour, seven-day-a-week services.
The fund was set up with Libor fines levied on UK banks, and supports search-and-rescue volunteering by helping with the costs of operational training.
There is no maximum amount charities can apply for, and the fund will provide up to 80 per cent of the cost of training each volunteer.
Collaborative bids from different groups of organisations or charities are also encouraged, CAF said.
The deadline for applications is 23 September, with successful applicants getting notification in November and receiving grants in April.
The training must take place within a year of the organisations receiving the grants.
Charlotte Burke, grant-making manager at CAF, said: "In the past, this money has helped pay to train volunteer first responders, flood-rescue boat crews, open-water lifeguards and mountain-rescue teams, helping to improve the safety and quality of UK search-and-rescue services across the country.
"This year we are particularly keen to encourage smaller organisations to apply and to expand the cover across the UK."
