We tend to believe that mature markets, well-established and with significant barriers to entry, are not worth entering to compete in. And this makes perfect sense.

But some companies change the rules. Like Octopus Energy, which has shaken up the energy market in the United Kingdom. A company that, in just 9 years since its launch, has managed to overtake all the major energy companies and proclaim itself the market leader with a 24% market share. The upward trend in the graph over the past few years is impressive. (Source: Bloomberg)

And it’s no coincidence. Octopus has pushed many of the right buttons to achieve this meteoric rise.

The four key pillars of Octopus’s strategy that have driven its success.

To begin with, entering with a challenger mindset: better prices and better service. Greg Jackson, founder of Octopus Energy, makes it very clear: “We are the UK’s largest energy supplier thanks to better service, lower prices, and greater innovation. Our investment in technology has enabled this rapid growth while maintaining very high quality.”

Doing so with a winning value proposition: clear and designed to address many of the pain points of traditional energy companies.

• Green and Sustainable Energy: Supply of 100% renewable electricity, supporting the transition toward a clean energy system.
• Transparency: Clear pricing with no fine print, surprises, or hidden costs, aiming for long-term sustainability.
• Better prices thanks to technology: Such as the “Agile” smart tariff, which adjusts electricity prices according to supply and demand, allowing customers to consume energy when it is cheaper and more abundant. Similarly the Kraken technology: a proprietary data and AI platform that optimizes energy management, facilitating electrification (EV chargers, heat pumps) and improving efficiency.
• Excellent Customer Service – “Exaggeratedly Good”: Fast support (response promised within 2 minutes) with dedicated and approachable teams.
• Promotion of Self-Consumption and Integrated Solutions: Encouraging industrial and residential self-consumption, with services that include the installation of solar panels.

On top of that, they have managed to build a strong company culture that makes them unstoppable. In the founder’s own words: “We were recently recognized as the best company to work for, which proves something obvious: world-class technology and a happy team lead to satisfied customers.”

But there is another key ingredient that has allowed it to become a winning player: its brand. A very well-defined brand, fully consistent and highly distinctive, which has been the perfect vehicle to communicate and amplify the company’s strong value proposition.

As Rory Sutherland, Vice Chairman of Ogilvy, says, if there were a parallel universe in which they had called themselves GreenTech.com (or some descriptive and boring name) and didn’t have a pink octopus as their logo, in that parallel universe they would have gained 30,000 customers instead of the more than 7 million they have today. I’m leaving a link to a short video here where he explains it.

Octopus Energy’s brand as a major business asset

To understand why the Octopus Energy brand works so well, we can analyze it through the Noxis Brand Creation Cycle, a model that breaks down all the ingredients that make a brand powerful and coherent, from its strategic core to its visible expression.

The starting point: the TARGET. Everything begins with knowing who you are addressing. Octopus targets the conscious and informed consumer: someone tired of overpaying, of not understanding their energy bill, and of feeling poorly treated by the large energy companies. A profile that in 2015 seemed like a minority, but was in fact the spearhead of a massive cultural shift.

01. Brand proposition. Their point of view is clear and honest: “We believe energy could be fairer for people and more sustainable for the planet.” And their promise makes it concrete in a memorable way: “Smart energy for smart people.” A phrase that connects the product with the customer and that, in such an uninspiring sector, feels refreshing and distinctive.

The three pillars of the proposition are equally concrete: fairer (price transparency), cleaner (100% green energy), and more human (real, person-to-person customer service). This is how clearly they express it on their website:

02. Brand Essence Attributes: The five attributes that define the soul of Octopus are: intelligent, sustainable, affordable, transparent, and approachable. What is interesting is that they combine the rational (price, technology, sustainability) with the emotional (they take care of me, I trust them), thus appealing to both the head and the heart of the consumer.

03. Brand Personality Attributes: This is where Octopus radically distances itself from the rest of the sector. Its personality is friendly, likeable, optimistic, and deliberately simple, without any pretension of sophistication. It doesn’t speak like a large corporation. It speaks like someone close to you who genuinely wants to help. And this personality remains consistent across all its touchpoints, which at scale is extraordinarily difficult to achieve.

Up to this point, we have looked at the brand strategy, what is not visible. As we can see, it is a faithful reflection of its value proposition and business strategy. Now let’s look at how they built the brand expression, what we actually see, hear, and experience from the brand.

04. Verbal Identity: The name “Octopus” is, in itself, a declaration of intent: it does not describe anything about the sector, and as Rory Sutherland rightly points out, this is a huge advantage in terms of memorability and differentiation. Its claim “Green energy. Fair prices. Always.” summarizes the proposition with surgical precision, and that final “Always” is no coincidence: it is a promise of consistency in a sector where consumers distrust promotional offers. Its slogan “Change is that simple” further reinforces accessibility and removes the psychological friction of switching providers.

05. Visual Identity: Purple as the corporate color and the pink octopus mascot, which is also part of the logo. A bold branding decision, and an extremely successful one. In a sector dominated by corporate blues and generic greens, Octopus opted for a mascot with its own personality and an unusual color. The result is a DISTINCTIVE and DIFFERENTIATED brand, instantly recognizable and capable of generating immediate sympathy. As Sutherland says, that octopus is worth millions.

06. Experiential Identity: Perhaps the most powerful asset and the hardest to replicate. The experience of being an Octopus customer is perfectly consistent with everything mentioned above: responses in less than two minutes, approachable and solution-oriented teams, and transparent communications. The brand doesn’t just promise, it delivers. And that generates the best fuel for marketing: genuine word-of-mouth recommendations.

Consistency, the key to everything

What truly makes the Octopus brand powerful is not any of these elements on their own, but the consistency between all of them. As we always tell our clients, what matters is that the logo, the name, the colors, the tone of voice… everything that makes up the brand’s verbal, visual, and experiential identity is an expression of the strategy. When a brand achieves that 360-degree alignment, it becomes something with real substance, something difficult to replicate and, most importantly, a source of growth for the business. And that, in a market as competitive as the energy sector, is a fundamental competitive advantage.

Does your brand have the differentiation and consistency of Octopus?

Building a powerful, coherent, and differentiated brand like Octopus is not a coincidence. It is the result of well-executed strategic work, from defining the target and the brand proposition to every detail of its visual, verbal, and experiential expression.
