Congdon had served as a councillor for many years and served as Deputy Leader of Croydon Council. He was first elected to the House of Commons at the 1992 general selection, succeeding the outgoing speaker Bernard Weatherill who was retiring from the Commons.

The Croydon seats were reorganised ahead of the 1997 general election, with the loss of one seat. Congdon competed against Sir Paul Beresford, then-MP for Croydon Central, for the Conservative Party nomination for the new merged seat and won. He then lost in the ensuing election in 1997 to Labour's Geraint Davies. Sir Paul Beresford, meanwhile, successfully contested Mole Valley and continued as an MP.

Congdon stood once again against Geraint Davies at the 2001 general election and lost. He then worked for MENCAP, and did not stand again at the 2005 election, when the Conservative candidate Andrew Pelling recaptured the seat from Davies.

Congdon is now retired and lives, with his wife Theresa, in Old Coulsdon. He has one daughter Rebecca and two grandchildren.
