UK Supermarkets Market Report 2025

"Value-for-money remains top of the consumer agenda, but moving forward large-format stores have to lead more on the healthy eating revolution"

Michael Oliver, Senior Retail Analyst

UK Supermarkets Industry – Trends and Insights

  • The supermarket channel is estimated to grow by 2.1% in 2025 in value terms. However, adjusted for inflation, volume sales fell and the channel continued to lose share of the wider market.
  • Volume decline is not a trend unique to large-format stores, with 47% of shoppers actively cutting grocery spend, but a growing need for convenience better insulated rival channels, namely discounters and online, from volume decline.
  • In a high inflationary market, margins in the sector have been squeezed both due to external factors and the growing price-war, as leading players react to shoppers’ demands for value.
  • The biggest threat to large-format stores is complacency, failure to sharpen value perception and differentiate in a crowded market.
  • The biggest opportunity lies in bold repositioning: using tech and consumer demands for wellness and experiential formats to redefine the role of the physical store. The largest players are uniquely positioned to leverage data, technology and store space to move beyond simply price leadership, to experience-rich, health-centric destinations.

Key Issues Covered in the Report:

  • The size of the UK grocery and supermarket sector, and the continued evolution in channel use
  • How consumers are balancing need for value with rising interest in health, wellness and transparency
  • Key drivers of retailer choice, including the impact of price, store design and technology
  • The evolving role and expectations of loyalty schemes in driving patronage
  • Attitudes towards shopping for groceries, including impact of retail media and use of AI

Report Scope

The main focus of this Report is the supermarkets of the market leaders – those stores in which people have historically done their main shop.

The term ‘supermarket’ takes in a very broad selection of store sizes. Tesco, for example, has stores ranging from 10,000 sq ft, small high-street supermarkets to over 100,000 sq ft hypermarkets, with an average supermarket size of around 39,000 sq ft. Broadly speaking, the unifier between these stores is the ability to serve, first and foremost, a shopper’s main shop, or primary grocery needs. As size increases, the range of non-foods and other services accommodated also increases, with the trade-off being that the largest stores are usually located outside of urban areas and often need a dedicated trip to visit.

While touched upon in this report, discounters are excluded from our definition of supermarkets as, while often similar in size to the supermarkets of the leading players, in reality they fall between the supermarket and convenience sectors.

What goes into a Mintel Market Intelligence Report?

Curious about how a Market Intelligence report comes together? We like to think of it as building a detailed puzzle. We start with individual pieces: data from consumers, market statistics, industry trends, and online conversations. Then our expert analysts add world-class human insight and industry knowledge. The pieces are assembled to reveal a clear, comprehensive picture of a market.

The Four Pillars of Our Research

We use a combination of four main research methods when creating our reports, each adding a valuable perspective:

  • Consumer Research: Direct surveys with real people, giving us clear, current insights into what people think and do.
  • Desk Research: In-depth review of trusted data sources. We use this rich database, plus powerful internal tools that track new products and market sizes, to detect trends and guide forecasts.
  • Trade Research: Insights from conversations with industry experts. Their real-world experience helps us understand what’s happening behind the scenes.
  • Brand and Social Media Research: Analysis of online opinions and trends. This lets us spot trends, measure brand sentiment, and capture feedback in real time, adding further depth to our research.

Bringing It All Together

Each of these four pillars provides a different piece of the puzzle. Consumer research tells us what customers think, desk research provides the factual framework, trade research offers an insider’s view, and social media analysis reveals public sentiment.

Our expert analysts are skilled in weaving these diverse data streams together. They apply a range of quantitative and qualitative analysis techniques to uncover the deeper story, connecting the dots to deliver clear, actionable insights. This comprehensive, multi-layered process is how we transform raw data into a market intelligence report you can trust to inform your most important business decisions.

When I’m investigating specific sectors I tend to use Mintel reports for their forecasting, which I’ve always found to be very accurate.

They also offer really broad and deep coverage in their reports. They are very, very detailed. For example, we were able to gain insight across a wide range of business areas from just one report, proving that Mintel is excellent value for money.

So overall, it’s the level of detail and the quality of forecasting that really stand out for me.

Mintel helps us when we want to know something quickly – it provides fast answers to our questions. If we need to get a view of what’s going on in a particular market it’s very useful.

When carrying out background research, I find Mintel an excellent starting point.

The fact that it covers so many markets is a big plus for me– instead of having to buy specialist products in each area we are interested in, especially when we only require a brief view on a particular market, we can go to Mintel for help as a one-stop shop. I find Mintel a useful and valuable resource.

One of the biggest challenges we face is the need to get smart on a business or category real quick.

We are talking to clients who live and breathe their category every day and the expectation is that we will be able to get caught up very quickly, and bring the thinking that can help them.

We need to do that often in a matter of days, so it’s not a small ask. Mintel gives us a very articulate view of category conditions and does so at the speed we need it.

We use Mintel to inform our thinking and reinforce strategy. If you’re presenting new ideas, it’s essential they are underpinned by robust data and evidence, and clearly rooted in fact.

Mintel gives us all that. It’s a great brand and one that is trusted by clients.
