On 18 November 2006, Kandol scored an injury time winner against Rochdale at Underhill to complete his hat-trick that also saw Barnet win their third consecutive league game.

[7] After scoring 18 goals from 21 games for Barnet at the start of the 2006–07 season, Kandol joined Championship club Leeds United in a two-month loan deal on 23 November 2006.

[10] After Leeds were relegated to the third tier of English football for the first time in their history, Kandol scored a last-minute winner against Tranmere Rovers in the opening game of the 2007–08 League One season.

[14] Leeds signed forwards Luciano Becchio and Enoch Showunmi during the 2008 close season, and Kandol was allowed to join Millwall on loan until January 2009.

[16] In September, he was sent off in the last few seconds for a bad tackle on Leicester City's Michael Morrison,[17] then marked his return from the resultant three-match ban by scoring twice in the first 12 minutes against Tranmere Rovers.

[18] Following that, Kandol then went on to score another two against Bristol Rovers, one at Carlisle, and one against Huddersfield winning him several man of the match awards, becoming top scorer at the club and helping Millwall to rise to 2nd in the League.

[21][22] Two weeks later, he came on as a late substitute to score the last of Leeds' four goals against Yeovil Town but was charged with violent conduct in an incident after the final whistle and received a three-match ban.

However, after seemingly agreeing terms on a one-year contract he failed to turn up to training as arranged on 4 August and a scheduled press conference.
