Most Popular Supermarket in the UK: What Spending Data Shows

Ask a group of Britons where they do their weekly shop and you will soon have a lively debate on your hands. Supermarket loyalty is personal, tied up with where we live, what we budget and what our routines look like. But when you look at actual spending rather than brand affection, one name stands clear. Here is what the numbers say about the most popular supermarket in the UK.

Tesco is the most popular supermarket by a distance

Consumer spending analysis by Zable shows Tesco accounting for 33.6 per cent of all supermarket transactions nationwide. That is more than a third of the market for one retailer. Foot traffic there peaks at around 5pm, as commuters pick up ingredients for the evening meal.

A tight race for second

Sainsbury’s narrowly beats Asda to second place, with nearly 15 per cent of transactions against Asda’s 14.4 per cent. Geography plays a big part. Sainsbury’s is strongest in London, where it makes up almost a quarter of grocery purchases. Asda finds its biggest strength in northern heartlands and post-industrial towns.

It is a good reminder that regional loyalty still shapes where people spend.

The rest of the table

Further down, the figures look like this:

• Aldi: 10.5 per cent
• Morrisons: just over 10 per cent
• Lidl: 9.5 per cent
• Marks & Spencer Food: 4.7 per cent
• Waitrose: 1.6 per cent

Age is part of the story as well. Aldi, Lidl and Asda draw their strongest customer base from shoppers in their forties. At the premium end, Marks & Spencer Food and Waitrose attract the oldest customers in the study, with people aged 50 and over making more than a third of purchases at both.

Takeaways and coffee stops

The analysis went beyond the grocery aisle too. In fast food, McDonald’s takes nearly eight out of every ten transactions. At lunchtime, the winner is Greggs. The bakery chain has overtaken traditional cafes to become the UK’s most popular coffee shop by transactions, with footfall peaking as the lunch hour arrives.

What it tells us

The figures are based on transactions rather than opinion, which is what makes them interesting. It is one thing to say you prefer a particular shop, and another to see where millions of everyday purchases actually happen. The gap between first and second place is big, while the gap between second and third is razor thin, so the race for the runner-up spot looks set to stay lively.

If you are curious how your own habits compare, think about when you usually shop and where. Plenty of us fall into a pattern without noticing, whether that is the after-work dash for tea or the Saturday morning stock-up. The data suggests those little routines, repeated by millions of households, are exactly what shape the high street and the rankings we see here.

The split between age groups is interesting for anyone curious about who shops where. The discounters lean towards middle-aged households, while the premium names lean older, which suggests that budget, habit and stage of life all play a part in the choices we make at the checkout.

From the evening dash at Tesco to a lunchtime sausage roll, the data paints a clear picture of daily British life. We like convenience, we stay loyal to our regions and we know exactly which brands we turn to. Whether your trolley heads for the big blue, orange or green logo, there is a good chance plenty of your neighbours are doing the same.
