Ward became the MP for Watford at the 1997 general election, succeeding the former Conservative PartyDeputy Chief WhipTristan Garel-Jones who had retired, and defeating Conservative candidate Robert Gordon by 5,792 votes. Elected at the age of 24, she was not quite the youngest MP, being 50 days older than Chris Leslie, the new MP for Shipley. After her election, Ward became a member of the Culture, Media and Sport Select Committee. From 2000 to 2002, she was the Chairman of the All-Party Parliamentary Chocolate and Confectionery Industry Group. In the 2001 general election she retained her seat by 5,555 votes and was appointed as Parliamentary Private Secretary to John Hutton. The increasing dominance of local politics in Watford Borough council by the Liberal Democrats, including the election of a Liberal Democrat Mayor, led to speculation that Ward would find re-election extremely difficult. Ward even accused staff from the council of harassment during the 2005 general election campaign. However, she managed to hold off a strong Liberal Democrat challenge from Sal Brinton; despite a 12% swing against her, Ward held the seat with a majority of 1,148 votes, approximately 2.3% of the electorate. The Conservative candidate was narrowly forced into third place with 793 fewer votes than Brinton, making Watford a three way marginal seat. Upon her re-election in May 2005, Ward was appointed an Assistant Government Whip before being promoted to full Whip, as a Lord Commissioner of HM Treasury, on 5 May 2006. She was promoted again in October 2008 to Vice-Chamberlain of the Household, the lowest of the senior Whips. At the June 2009 Cabinet reshuffle, she replaced Shahid Malik as the Parliamentary Under Secretary of State for Justice. She claimed over £90,000 in second home allowance between 2004 and 2009, despite living less than 30 miles from Westminster. Upon publication of MP's expenses in 2009, Ward defended her choice to fund a second home in Westminster from her parliamentary allowance, citing her need to balance her public duties with her duties as a mother of small children. Ward was one of 98 MPs who voted in favour of legislation which would have kept MPs expense details secret. She lost her seat at the 2010 general election when she finished third in the election in Watford with 14,750 votes, behind the Conservative Party candidate Richard Harrington and the Liberal Democrat Sal Brinton.
