Value grocer Lidl has reported record Christmas trading and said its seasonal performance was the best in food retail.

Lidl’s sales climbed 17.9% year on year in the four weeks to December 27, which it said meant it was ā€the fastest-growing retailer versus the big four supermarkets and main competitorsā€.

The grocer said popular Christmas products such as mince pies drove customer spend, helping its basket size increase 24.8% year on year.  Lidl said shoppers switched Ā£34.7m of spend from other supermarkets to it and the Lidl Plus rewards app had also attracted customers.

Lidl GB chief executive Christian HƤrtnagel said: ā€Despite this Christmas being a difficult time for many across the country, we are pleased to have been able to help our customers enjoy themselves by offering high-quality food at the lowest prices on the market. Our record sales and significant basket size growth just demonstrate the strength of the Lidl appeal.

ā€As we look ahead to this year, we remain committed to our expansion and investment plans, offering more customers up and down the country our great quality, unbeatable value offer.ā€ 

Lidl opened four new stores in December. The grocer is investing Ā£1.3bn over the next two years as it chases a target of 1,000 branches by 2023.
