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.
The first Mintel Market Intelligence report was published over 50 years ago. Since then, we have provided our unique insights and understanding of consumers, innovation and global markets to thousands of customers worldwide. Here’s why our customers rely on Mintel:
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.
We use a combination of four main research methods when creating our reports, each adding a valuable perspective:
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.

We use Mintel Reports, mostly for financial services and ecommerce markets, plus a few retail and technology ones.
As a leading payments provider, we value additional insights into consumer behaviour, opinions and trends that are shaping the many different markets we operate in. Mintel is a very good and very quick way for us to obtain those insights.
We use Mintel to get a view on where a particular market is going, which can support us in product development and help us identify opportunities or indeed risks, it is a very useful barometer of a market’s potential.
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.
Mintel is really good for getting a handle on a particular category quickly. If we are working on a new business pitch in an area we don’t have much experience in, it’s a brilliant way to get up to speed with what’s going on, what’s changing and what the key trends are in any category.
It’s very rare now that anyone will plough through a 200-page report – that’s why the summaries are really useful. We know they are backed up by a lot of detail, so if you need to go into something in more depth you know the information will be all there for you.
There is no question that Mintel is the go-to resource for the best quality market research, but I did not think it was an affordable option for Abacus Marketing to consider. As a small marketing agency, we only work with a few new clients each year.
However, we have a very high-end consultative approach to our work, so we really do need a partner like Mintel to provide the big agency experience we are always aiming to deliver. Our clients come from an incredibly diverse range of industry sectors, so we obviously need access to market research reports from a very wide spectrum of marketplaces – and that is precisely what we got.
We’ve found it so useful working more closely with Mintel. They helped support our recent flagship event for our top suppliers by providing a really unique viewpoint on the future of online retailing.
Nick Carroll from their Retail Team was also an excellent panelist, sharing useful and actionable consumer insights. We definitely look forward to working with Mintel again on future projects.
