The 129-year-old company spends an estimated £200 million on marketing, the bulk of which is in the US.
WPP’s Maxus has handled the global account since 2011. The UK business is worth an estimated £5 million.
The news follows a review of SC Johnson’s global media planning, which was consolidated into Omnicom’s PHD in January. That process lasted 12 months.
The buying review will be led from the US, with local markets assisting the process when required. SC Johnson is present in 70 markets.
The company had not confirmed the review at the time of press. Maxus declined to comment.
