Lidl hired its loudest sceptics for a day on supplier farms — and filmed it

Prove authenticity, provenance and quality behind the discount prices, starting with Lidl's Deluxe Scotch Beef, and realign perceptions with transparency rather than claims.

Recruit 'anti-advocates' — real sceptics found via social media — to work a day at Lidl's supplier farms and film their genuine conversion for the ad.

Premiering in the first Coronation Street break of July 2016, the films took sceptic Sharna to Perthshire beef farmer John — supplying Lidl since 2010 — for his daily cow count, where she learned his herd is 100% Scotch Beef; a second film sent Chris out at dawn with a mussel farmer on the Isle of Mull. TV, cinema, press, radio, digital and social carried the series.

Lidl reported the campaign followed TBWA's Easter and Christmas work that had grown sales 17.7% to a 4.4% market share, and that both featured sceptics left as 'complete Lidl converts'.

Lidl UK knew its problem: low prices made customers doubt quality. For the latest chapter of #LidlSurprises, created with adam&eve TBWA, the supermarket premiered a new campaign in the first break of Coronation Street, addressing authenticity, provenance and quality head-on with Lidl's Deluxe Scotch Beef.

The strategy was to be 'deep rooted and transparent on where our products come from', as advertising and marketing director Claire Farrant put it — and the casting was the idea. Lidl approached real-life sceptics, discovered via social media and independent market research, and offered them a job for a day at the farms of Lidl suppliers.

The first film went to a farm in Perthshire, Scotland, where beef farmer John — supplying Lidl since 2010 — took anti-advocate Sharna along on his daily cow count to answer her concerns; she was surprised and happy to learn his entire herd is born and bred in Scotland, 100% Scotch Beef. The second sent Chris, who had questioned the seafood's provenance, out on Scottish seas at dawn with a mussel farmer on the Isle of Mull.

Managing partner Andrew Chisholm called it 'an exciting and potentially risky strategy' — introduce a real-life sceptic to real farmers and real Scottish weather, then just let the cameras roll. The integrated campaign ran across TV, cinema, press, radio, digital and social, following TBWA's Easter and Christmas work that had helped Lidl grow sales 17.7% to a 4.4% share as the fastest-growing supermarket.

The sceptic is the ad: her questions write the script and her face carries the proof.

Unscripted conversion is a claim discounters can't buy with production value alone.

Letting critics keep their doubts on camera made the eventual reversal feel earned, not staged.

Don't answer your critics with a manifesto — put them on the farm payroll and let their own faces make the claim.

The source reports no follow-up tracking; it notes both anti-advocates became 'complete Lidl converts'.
