Development Squad midfield player Joe Maloney will remain with Calor League Premier Division Burnham for the rest of the season.
Joe linked up with the Buckinghamshire club in late November and initially signed a deal until January 4.
He will now stay with Burnham for the rest of the 2013/14 campaign.
Joe has played four games for Burnham so far and they have won three and drawn one of them.
He was, however, sent off for two bookable offences in his third game.
Ose Aibangee, Brentford FC Academy Director, said: “Joe’s loan spell at Burnham has gone well so far.
“Although he was sent off in one game, he has made an impact and got some regular football.
“It is not easy to play games in close succession at Christmas and on pitches that aren’t always the best.
“Joe has come through it well and made a contribution.
“That Burnham wanted to keep him tells us how well it has gone.
“We are pleased Joe has the opportunity to play more First Team football, he will continue to learn lot playing non-league football and it will aid his development.”
Joe came through the Brentford youth ranks and signed a two-year scholarship in the summer of 2011.
He had two injury hit years and was given an extension to his scholarship to take him to October 2013.
He signed a professional contract until the end of the 2013/14 season as part of the Development Squad and has played two Under-21 Professional Development League Two South games this term.
Joe, 18, played 12 Under-18 Professional Development League Two South games last season and made one appearance in the FA Youth Cup.
He also played three games for the Development Squad last season.
