Karmarama, Leo Burnett, VCCP and WCRS are vying for Lidl's £70m advertising account after the supermarket called a review in August.
Pitches will take place during the first week of December. The process is handled by AAR.
Karmarama previously worked with supermarket rival Iceland but split with the brand earlier this year.
Lidl kicked off the review after parting ways with TBWA\London. Over TBWA’s five-year stint on the account, Lidl increased its share of supermarket customer spend from 3.1% in 2013 to 5.5% in the summer, according to Kantar Worldpanel data.
However, Lidl has fallen behind its German rival Aldi, which grew its share over the same period from 3.6% to 7.6%.
Lidl’s review is the second in the supermarket sector this year, after Asda dropped Saatchi & Saatchi and hired Abbott Mead Vickers BBDO.
