Londis will remerchandise chillers at members’ stores for free to boost the category that has margin returns of 25%.

Following a £2.5m investment at its RDC operations, Londis has increased the guaranteed date-life of over 100 short-life chilled products.

Trading controller Kenton Burchell said: “The chilled food category has grown fastest among all symbol group sales.”

Retailers will be paid a £100 cash bonus if they use the new Londis planograms for at least three months.

The planograms for chillers range from 2.4m to 10m and snacking cabinets range from 1.2m to 2.4m.
