How Clean Is Your House? was a British entertainment/lifestyle television programme in which expert cleaners Kim Woodburn and Aggie MacKenzie visited filthy homes and then cleaned them. The thirty-minute show was produced by Talkback Thames, the UK production arm of FremantleMedia (itself part of the RTL Group), and airs on Channel 4 and many of its subsidiary channels. It was first broadcast in 2003 and was an immediate ratings success. In November 2009, Channel 4 announced that they had decided to cancel the series in order to make way for new programming.
