Aldi has joined the British Retail Consortium, as new figures confirm the growing success of discounters.

The German discounter joined the likes of Tesco, Asda and Sainsbury’s while celebrating 19.8% sales growth in the past year, and a record 3% market share, according to the latest figures from TNS Worldpanel.

“This growth is entirely driven by new stores and new shoppers – spend levels for existing shoppers remain unchanged and quite low compared with the top four,” said Ed Garner of TNS Worldpanel. 

Aldi claims its growth is as high as 40% in July and half of its shoppers now come from the ABC1 demographic.

“As we continue to expand rapidly and take a greater share of food retailing in the UK, we’ve joined the BRC for its excellent links with politicians in Britain and Brussels and its knowledge of the policy areas that impact most on our business,” said Paul Foley, MD of Aldi UK Ireland.

The BRC director general, Stephen Robertson, extended a warm welcome. “Aldi represents an important part of the UK grocery market and I’m pleased we will be able to represent their viewpoint,” he said.
