Broncos have agreed a ground share with Barnet FC to play home games at The Hive as well as training at Barnet's former ground, Underhill.
This agreement secures the club's future and averts the threat of administration.
Broncos chairman, David Hughes, said: "Our focus has always been to ensure we made the right decision going forward. Over the last 10 days, we have worked closely with the Rugby Football League and Barnet chairman, Tony Kleanthous, to avoid administration and secure the future of the Broncos.
"I believe this is the right decision, not only for the club, but also for the future of Rugby League in London.
"Many hours have been spent working to make sure the Broncos are positioned in an environment where they are best able to prepare and compete at the highest level.
"I'd like to thank Chief Executive, Gus Mackay and our staff for the long hours they've spent working to make sure the Broncos survived
"I'd also like to thank the RFL Board and its Executive, in particular Blake Solly who have also worked tirelessly in their efforts to find a solution."
Gus Mackay added: "These discussions have been ongoing for six months and I'm personally delighted they have reached a successful conclusion for an exciting future.
"The facilities at The Hive are outstanding and the excellent transport links around the ground make it a perfect venue for Rugby League in London.
"The initial agreement is for the 2014 and 2015 season with a view of a longer and permanent agreement.
"I'd also like to thank the players, staff and loyal fans for their patience and understanding through this period of negotiation. Now we can all move forward positively"
Tony Kleanthous said: "We are delighted to welcome the London Broncos into our family here at The Hive.
"This deal represents a new beginning for the club and we hope to work with them in the community to grow the participation and support of Rugby League in North London.
"The Hive is a £26m internationally recognised training complex incorporating a stadium, sports science unit, gym, conference centre and state of the art medical facility.
"We are proud to enhance the number of resident clubs here and host the Broncos alongside the Bees. I feel these are exciting times ahead for both clubs and I cannot wait to take my seat for our first RL match next year."
