Allsopp has worked as a real-estate agent, a sales and letting negotiator and a relocation agent in
Notting Hill, London. She had her own company, specialising in finding houses, managing moves and providing after-sale services to new home-owners. In 2006, she temporarily replaced her sister Kirstie as co-presenter of
Location, Location, Location, while the latter was on maternity leave. During this period, she presented an episode in which
Hackney was voted as the worst place to live in the UK, which caused some controversy. In 2008, she began hosting the Canadian television show
The Unsellables on
HGTV (Canada). Her role on the show was to help people sell their "unsellable" homes. The programme has since been broadcast on the U.S.
HGTV and on the
BBC in the UK, in which Allsopp is paired with property expert John Rennie. ==Personal life==
