E4 will air at least two more runs of the constructed reality show, which follows the lives and romances of a selection of West London socialites.
Spencer Matthews, Millie Mackintosh and Ollie Locke are all expected to return to the show, but producers are searching for new personalities to join the programme.
Caggie Dunlop and Hugo Taylor have both quit Made In Chelsea, so there is room for expansion in the cast.
Spencer Matthews told Digital Spy that his recent stint on Channel 5's The Bachelor shouldn't affect his position on the show.
Made In Chelsea, which first aired in May 2011, has been a hit for E4 online and was nominated for a BAFTA earlier this year.
