Plans were recently unveiled for an ambitious scheme that will see the Terence Conran-founded museum move from Shad Thames into Kensingston's Commonwealth Institute.
After beating two others in a pitch process, Bolton & Quinn, which had been working with the museum on a public affairs brief since September 2010, will now focus on a consumer-facing retained brief.
Josephine Chanter, head of communications at the museum, said the pitch process was part of a review as the public affairs brief turned into a consumer-facing one.
‘It was focused on raising the museum's profile, because as a successful small museum we really want to increase awareness.’
The new museum will be based in Kensington’s cluster of cultural heavy hitters, including the Natural History Museum, the Royal College, Science Museum and the V&A.
It can hold twice as many people, with hopes that the museum will be able to double visitor numbers to 500,000.
Bolton & Quinn can list The Royal Academy of Arts, the Guggenheim Museum in Bilbao and Anish Kapoor among clients.
Chanter added: ‘Because of their previous work there was huge confidence that they understood the journey we are on. We will be looking to roll out a multi-pronged approach to spread the word through news and feature opportunities, leading the agenda and positioning ourselves at the heart of the debate.’
