"We have spent the last 24 hours to search for venues but with a busy schedule of football matches this weekend we have been severely limited in our choice of alternative venue," said chief executive Gus Mackay.
"We wanted to avoid backing up fixtures and we were keen for the team to maintain their momentum following the performances over Castleford Tigers and Hull FC.
"The ground at Esher has been approved by the RFL for this one-off game. We are grateful for the support from the RFL and for Esher Rugby Union Club for hosting us at short notice.
London Broncos head coach Tony Rea said: "The situation was explained to the players, and they were given the choice and they were unanimous with their support of playing the game at Esher."
