The agency was appointed without a pitch and there was no incumbent on the account.
Servis was recently acquired by Turkish manufacturer Vestel and will be relaunched in January 2013, with a planned £1.5m per-year media budget.
This year it will run a digital campaign targeted at people looking to replace their washing machines, and a print campaign for its retro fridge freezers, with creative by Brocklebank Penn.
Simon Hedges, category manager for Servis, said: "The7stars answered our brief perfectly and the targeted media campaign around our relaunch and new products will really put us in the forefront of consumers' minds.
