Why Aldi and Lidl will keep on growing

UPDATE: The Big Four grocers are growing again, but the German onslaught is far from over.

It’s four years since German budget supermarkets Aldi and Lidl began in earnest their assault against the established ‘Big Four’ British grocers. Both stores had been slowly growing in the UK beforehand, but the hubristic expansion of Tesco, Sainsbury’s, Asda and Morrisons created a distinct opportunity.

The mood among shoppers had turned from range to convenience, while value was more important than ever. Burdened with a network of half-populated hypermarkets, Tesco and the gang were therefore woefully unready for the price war the expansive ‘discounters’ (they hate the term) unleashed.

Their campaign was a great success. Aldi overtook the Co-Op this year to become Britain's fifth biggest supermarket by market share, according to data from Kantar Worldpanel, while Lidl has just pipped Waitrose for seventh place. In the 12 weeks to 25 March 2018, Aldi commanded 7.3% of the UK grocery market, and Lidl was on 5.3%.

To put that in perspective, their combined share has grown nearly 80% since the summer of 2013. That's billions extra passing through their tills each year.

Every penny and every basis point was wrenched from the hands of the Big Four, who have gutted their own margins in an effort to stop the rot, leading to a period of groceries deflation from the middle of 2015 to the end of 2016. The rising pound pushed the sector into inflation last year, though this has calmed down in 2018. It stands at 2.5% over the latest period.

The end of the price war?

The rising tide of prices may have had a surprisingly beneficial effect on the Big Four, however. Having teetered on negative or negligible till roll growth for the last couple of years, they're now all firmly in growth territory. Tesco and Morrisons lead the pack with 2.4% growth over the period, followed by Asda (1.8%). Sainsbury's trails at 0.6%.

Aldi and Lidl 12 week market share, viewed in 12 week increments, showing especially strong annual growth in the spring. For more detail, take a look at Kantar Worldpanel's interactive chart.

Those who would hope Aldi and Lidl are just going to go away will be disappointed. Their till rolls were both up 10.7% and 10.3% respectively, dwarfing the others.

More importantly, they have permanently changed the dynamics of the grocery market by forcing down margins. While the big supermarkets can live with that, albeit as less profitable entities than they once were, it means they will need to continue shutting their less profitable stores to shore up their balance sheets. The discounters on the other hand have low prices built into their business models from the beginning, emphasising bulk over brand and price over range. 

Without a depreciating UK property portfolio hanging around their necks, Aldi and Lidl remain well placed to expand into the gaps their rivals are leaving.

In November 2014, Aldi announced a plan to increase its store tally from 450 to 1000 by 2022. It’s already more than a fifth of the way there. Lidl, on the other hand, just built its 700th storeis in February, building 40-50 stores annually.

To put that in perspective, Morrisons has just under 500 stores (though it has a much bigger footprint), while Tesco has over 6,000 including its Express convenience stores. There’s clearly still a long way to go before the discounters’ position in the market stabilises, but until then they will continue to expand their geographical reach and therefore market share.

If both German chains do indeed double their store numbers over the next several years, it wouldn’t be a tremendous leap to expect their market share to increase accordingly, by which time the term ‘Big Four’ may no longer be appropriate. Though their own-brand based business model makes it unlikely Aldi or Lidl will become market leaders, it's quite feasible to see them nipping at the heels of Morrisons before the decade is over. Get ready for the Big Six.
