London Broncos youngsters Harvey Burnett, Toby Everett and Joe Keyes have all signed professional contracts with the Super League strugglers.
The trio, all 18, currently play for the Broncos' Under-19 side and will join the first-team squad next season.
Outside back Burnett has signed for 2015 while forward Everett and stand-off Keyes have agreed three-year deals.
"We are planning for the future. It is pleasing they wanted to stay," head coach Joey Grima told BBC London 94.9.
"They have come through the system and are not only quality players but quality people."
The Broncos are bottom of the Super League table, yet to win a game this season and look set to be relegated from the top flight.
However, Grima says their recruitment plans for next season will not be affected by their current situation.
"The players know where we are," he said.
"A lot of them have aspirations of playing Super League and I would never prevent anyone from that or the opportunity to better themselves.
"We have identified the players we want to keep at the club but have got a back-up plan for players that want to move on. We are very proactive."
