The museum will then reopen in September at the London Lighthouse building, also in Notting Hill, formerly owned by the Terrence Higgins Trust.
The new premises will offer a modern conference space with breakout areas available for daytime hire for around 120 delegates, a large high-ceilinged space within the museum for evening hire for approximately 250 guests and its own garden.
Robert Opie, museum director, said: "With visitor numbers increasing, the new space will allow us to display more of the collection, and improve the visitor experience."
The Museum contains branded objects and design classics, alongside artefacts of daily life such as household appliances, toys and fashion, which demonstrate our consumer heritage and changing life in Britain over the last 150 years.
Sir Paul Judge, chairman of the museum, added: "This is an exciting and significant next step for the Museum and for London. The move will provide a better platform for learning on every level - the marketing community in particular will benefit from enhanced exhibitions and public programme facilities."
The Museum moved to Notting Hill in 2005 with the support of household names such as Kellogg’s, Cadbury, Diageo, Twinings, pi Global, Vodafone and McVitie’s.
