UK Mobile Network Providers Market Report 2026
"Evidence of consumers switching providers means MNOs will have to double down on promoting network resilience and building trust with their customers."
40% of consumers have been with their mobile network provider for over five years, reflecting how entrenched consumer habits are with their choice of mobile network. They value consistency and predictability, and while most consumers are happy with the network fundamentals, such as network speed, MNOs should nurture this incumbent advantage, by consistently making consumers feel valued.
The obvious danger for MNOs is that mid contract or unexpected price hikes create unnecessary friction. There is already evidence of switching behaviour, and financial uncertainty continues to influence consumer decisions. This can keep many in a defensive mindset, and on SIM-only contracts longer. With a median monthly spend of £16 for those on contracts, substantial price increases can lead to bill anxiety, prompting consumers to shop around for better deals, especially from value driven mobile virtual network operators (MVNOs).
With rolling month-to-month contracts growing, now reaching 26%, this offers networks the opportunity to lock down these transient users. For incumbents, it’s important to make it easy to switch to 12- or 24-month contracts that offer comparatively better savings in the long-term. Frame this as a savvy alternative to staying unmoored and poorer value SIM-only. Competitors can also offer compelling incentives, much like banks with current accounts, to attract consumers.
This report looks at the following areas:
Overview of the size of the mobile network providers market, including factors influencing the market’s trajectory over the next five years
Insights into shifting consumer behaviours, including preferences for contract types, durations, and the factors influencing their choice of mobile network providers
Analysis of consumer behaviour and motivations driving customer loyalty and decision-making processes
An analysis of how consumers perceive their mobile network providers, examining key factors like value for money, communication effectiveness, rewards and the elements that build trust
Actionable insights into areas where MNOs can enhance the customer experience, including an analysis of the improvements customers actively seek

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.

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.
Zac Steele, E-Commerce Trading Development Manager, Waitrose & Partners
We have such a great working relationship with Mintel on lots of different levels. As an insight partner, they have helped us to develop our business planning in specific categories as well as supporting our creative process but they’ve also been super helpful with facilitating our events in their inspirational offices near St Paul’s.
They’re an innovative company, with a client-focused team that always delivers.
Abby Carvosso, Group Managing Director, Bauer Media Group
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.
Andrew Neeson, Market Intelligence Manager, VocaLink
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.
Pauline Robson, Managing Partner, Mediacom
Working in a customer-obsessed organization means that data and insights have to be at our fingertips. Mintel’s reports help us support anecdotes with real quantifiable insights. The summary sections (which I really like) helps save time by giving a birds eye view of the content before spending time combing through the pages.
Our business review discussions are strengthened by the relevancy of the reports to help us better understand our customers. In addition, the customer service received from the team (especially in crunch periods) makes the process of understanding customer behavior even better.
