Nick Knowles and the team issue a call to arms and recruit friends, family and local trades to help transform the homes of families across Britain. Launched in 1999, after audience figures showed interest in other home make-over shows such as Changing Rooms, DIY SOS is a weekly full builder and designer level renovation of a section of a viewers home, taken on by a team of professionals after a viewers DIY project has gone wrong and not been finished. It is the longest running show of its format having been shown for over 10 years. Some believe it has cult status and even has an active dedicated forum. Launched with presenter Nick Knowles, the format consisted of a main project, and a small project initially headed by Lowri Turner (but after Lowri left the show, a number of subsequent presenters were used for the smaller segment), and a viewer call-in vote format voting for one of three families who have made short video pitches for their projects to be addressed in the following programme.
