Inferno won a competitive pitch against TBWA, Publicis and DDB that was led out of Electrolux's headquarters in Stockholm.
The agency will work across Electrolux's key European brands, including AEG and Zanussi, which produce washing machines, tumble-dryers, dishwashers, ovens and vacuum cleaners.
Creative on the retail account covers ads designed to drive customers into electrical retailers to buy products, rather than broader brand advertising.
Electrolux currently uses the Lowe Worldwide division Rivet to create its retail advertising. Lowe also handles the separate £25 million pan-European brand advertising account.
LBi oversees Electrolux's digital activity, while Tequila works on experiential and promotional campaigns.
