Shelbourne Chambers signed for Shelbourne at 11 years of age. He started out with the schoolboy teams and made his breakthrough into the first team during the 2004 season, at the age of 17, including being part of the Shelbourne squad during their successful 2004 European campaign. He did not make his first official first team appearance for Shelbourne until 15 August 2005 when he made his
League of Ireland debut coming on as a 2nd half substitute during a 1–0 defeat to
Cork City at
Turner's Cross. To aid Chambers with his development and to gain valuable experience, he was loaned out to
Waterford United for the 2006 season and instantly became a regular in their starting XI. Chambers returned to
Shelbourne for the 2007 season, but he was entering upon a very unfamiliar environment at
Tolka Park. Shelbourne were now in financial meltdown and were uncertain over their participation for the 2007 season. After the club was relegated to the
First Division, he made the decision to stay at Shels despite their relegation and keen interest in him from numerous
Premier Division clubs. As only one of two first team players retained by Shelbourne for the 2007 season, Chambers' talents were now of great importance to Shelbourne and he became one of the first names on the Shels teamsheet due to many impressive performances. He scored his first senior goal for Shelbourne with a delightful equaliser in a 1–1 draw with
Monaghan United at Tolka Park on 13 April 2007. Chambers departed Shelbourne after 10 years at the end of the 2008 season to move to
Britain. He made a total of 73 league and cup appearances for Shelbourne scoring 8 times.
Solihull Moors He went on trial at
Walsall, but was ineligible to play matches, so he joined
Conference North side
Solihull Moors on 16 January 2009 to get game time. Chambers' stay at Solihull Moors would be brief as he returned to Ireland in March 2009 to join
Drogheda United.
Drogheda United He made his competitive Drogheda debut on 13 March 2009 in 0–0 draw against
Bray Wanderers at
United Park. Chambers went on an amazing scoring streak in the 2009 season. He scored nine goals, including the all-important opener against Bray Wanderers in the relegation play-off, a match which finished 2–0 to Drogheda United.
Shamrock Rovers Following his impressive season at Drogheda United, Chambers joined
Shamrock Rovers in November 2009. In his first season with 'The Hoops', Chambers scored an impressive 11 league goals and won his first League of Ireland winners medal after Shamrock Rovers won the 2010 Premier Division on the final night of the season.
Hamilton Academical He moved to
Scottish Premier League team
Hamilton Academical on 25 January 2011. Chambers showed spells of his League of Ireland form whilst playing in the
SPL but Hamilton were relegated into the
First Division, and he left the club after a year.
St Patrick's Athletic Chambers was signed by
Liam Buckley for
St Patrick's Athletic in January 2012. Chambers impressed the Pats fans with his superb passing and found himself playing in a midfield role that saw him be the key to his sides attacks beginning. He picked up the
RTÉ man of the match award for his brilliant display including the assist for the opening goal by
Chris Forrester against his old club and
Dublin rivals Shamrock Rovers after the Saints ran riot and won 5–1 in a famous night. Chambers set up
Chris Fagan's opener against
U.C.D after an excellent slipped ball through the defence. Unfortunately Chambers' excellent form for Pats was interrupted for 2 months after he picked up an injury away to
Sligo Rovers. Chambers returned from the bench against
Bohemians in fine form and changes the game for Pats to win 2–1. Chambers played in all of the Saints games of their
Europa League campaign, where they knocked out
Íþróttabandalag Vestmannaeyja from
Iceland and
NK Široki Brijeg from
Bosnia and Herzegovina before being knocked out by German giants
Hannover 96 in front of 25,000 people at the
AWD-Arena. He played in the
2012 FAI Cup final at the
Aviva Stadium, as Pats lost 3–2 after extra time to
Derry City. Chambers was voted into the 2012 PFAI Team of the Year by his fellow
League of Ireland players, for an excellent season.
Return to Shamrock Rovers Chambers signed again for The Hoops in November 2012. He won the
2013 League Cup, the
2013 Setanta Cup and the
2013 Leinster Senior Cup (scoring in a 1–0 win over St Pat's in the final), however the season was overall a disappointing one for Chambers as Rovers finished fifth, with his old side Pats winning the league, and he left at the end of the season.
Return to St Patrick's Athletic Chambers signed back for champions St Patrick's Athletic for the
2014 season. Week after week he impressed fans, putting in a string of man of the match performances week in week out and retained his place in the midfield for most of the season amidst competition for places from
Keith Fahey,
Killian Brennan,
Greg Bolger and
Lee Lynch. The Saints disappointingly only finished third in the league but the season remained a success with third place earning a
Europa League spot for next season, winning the
2014 President of Ireland's Cup, the
2014 Leinster Senior Cup and most impressively, winning the
2014 FAI Cup to end a 53-year drought for the club since last winning the competition. He signed a new contract for the
2015 season in January 2015. On 19 September 2015, Pats won the
2015 League of Ireland Cup against
Galway United, with Chambers scoring his penalty in a penalty shoot-out win after a 0–0 draw at
Eamonn Deacy Park. Chambers had a very impressive season individually in a poor season for the team. He scored 5 goals in all competitions, 3 of them coming direct from freekicks. He was voted at the St Patrick's Athletic Player of the season for 2015 by the club's supporters for his excellent performances. Chambers was also voted into the PFAI Team of the Year by his fellow League of Ireland players.
