Line Up won the deal after a three-way pitch against rostered agencies BSI and Adding Value.
It is the fifth consecutive year that Line Up has produced the Indesit Company – which includes the brands Hotpoint, Cannon and Indesit - launch event.
Details for the product launch event are expected to be finalised in March, but are likely to include experiences focused on a centenary theme as Hotpoint celebrates its 100th anniversary this year.
Indesit Company’s events manager Jayson Weston said the annual product launches were the company’s "flagship events".
"As this is our centenary year, there’s even more pressure to deliver," added Weston. "Line Up has once again come up with some very original and exciting ideas that will add a fresh dimension to the event and will help Indesit Company begin the next 100 years in style."
Line Up managing director Duncan Beale said: "We are incredibly proud to have been entrusted with such a sought after brief. Our long-standing relationship with Indesit Company has given us an unrivalled insight into the motivations and characteristics of UK independent retailers, so we’re confident this experience will help Indesit meet its objectives."
