Top 100 most reputable companies in the UK revealed in major new study by The Harris Poll UK

The UK’s top 100 companies with the best reputations in the eyes of consumers have been revealed in a major new study by consumer research experts The Harris Poll UK, a Stagwell company.

Lego, Lush, Patagonia and Sony have emerged as the UK companies with the best reputations among consumers in the new 2025 Corporate Reputation Index – which surveyed over 10,000 UK consumers. At the other end of the scale, X, Evri, Royal Mail and Ryanair had the weakest reputation of all the companies in the index, reflecting ongoing challenges for these companies, including in customer trust and service reliability.

Based on an analysis of over 270,000 data points, the report measured reputation across 100 of the country’s most visible companies, spanning bricks-and-mortar, online-only and hybrid businesses. The Corporate Reputation Index ranks companies by their reputation across dimensions including Character, Trust and Trajectory.

Trends from the Harris Poll UK’s new 2025 Corporate Reputation Index:

• Challenger banks Chase and Monzo climb as traditional giants lose ground
  Innovation leads in financial services, with newer players gaining ground on traditional banks. Chase (19th) and Monzo (21st) both rank in the top 25, significantly ahead of HSBC (69th) and Barclays (64th). These results suggest that consumers are rewarding challenger banks that combine digital-first innovation by giving customers more control and flexibility which builds trust and transparency.
• Octopus Energy succeeds in the toxic energy sector
  Utility companies continue to face entrenched scepticism over fairness and value. British Gas ranks 88th and EON 80th, reflecting long-standing consumer frustrations, while Octopus Energy stands out as a rare exception at 14th. The findings demonstrate that Octopus Energy has step-changed these perceptions through a customer first approach to reshape reputations in a challenging sector that remains weighed down by historic perceptions of poor service and lack of clarity.
• The so-called ‘Discount Retailers’, like Aldi and Lidl, are on the rise
  The findings highlight how discount grocers are winning in the sector by using price as an ethical act, meaning they are perceived as on the side of the customer. Aldi (17th) and Lidl (28th) rank ahead of Sainsbury’s (35th), Waitrose (36th), Morrisons (70th) and Asda (72nd). Aldi and Lidl collectively now have 18% share of the grocer market and the fastest growing market share changing the dynamics of the sector.
• There’s a great divide between Technology companies and Social Media with companies like Sony, LG and Samsung drastically outperforming TikTok, Meta and X

There’s a divide happening between companies perceived as adding value by producing tangible products and services verses those companies where consumers are the product. Technology and consumer electronics companies are among the strongest performers in the Index, with Sony (4th), LG (7th) and Samsung (10th) all securing top 10 positions. For instance, Sony’s high performance on innovation shows how consumers reward advances that feel directly relevant. By contrast, Social Media companies like X (100th), Meta (94th) and TikTok (93rd) appear in the bottom 10 as content, safety and governance have impacted their reputations leaving them at the very bottom of the Index.

• Evri, Royal Mail and Ryanair face ongoing service challenges
  At the bottom of the Reputation Index sit Evri (99th), Royal Mail (98th) and Ryanair (97th). Each faces distinct reputational hurdles, but the common theme is consumer scepticism around trust and reliable products and services. For delivery companies such as Evri and Royal Mail, frustrations with service consistency and communication continue to weigh heavily. For Ryanair, its low-cost model presents challenges around consistent service delivery, particularly when things go wrong, and reinforces negative perceptions of customer care. The results underline how repeated negative experiences and high-profile controversies translate directly into long-term reputational damage.

Steve Brockway, chief research officer at the Harris Poll UK, said: “Reputation is a currency that can make or break a company in today’s UK market. Results from our corporate reputation study show that profit follows a clear and consistently well delivered purpose giving companies a sustainable license to lead their category. We’ve also seen that investing in your reputation enables a company to both endure and navigate their way out of a crises. In today’s polycrises of cost of living challenges and global instability, consumers are seeking havens of easy in a sea of hard – so it’s more important than ever to be seen as ‘on the consumers side’ when for many consumers, achieving idealised goals is simply out of reach.”
