I’m proud to share that SmartestEnergy Limited (SEL) is now the UK’s 3rd largest Commercial and Industrial (C&I) business supplier by volume, supplying 11.5 TWh, in the Business Retail Market Share report, published by Cornwall Insight. This milestone also sees us rise to 4th in the overall non-domestic market rank.

Since we established our retail business in 2008, we’ve been committed to delivering high quality customer service, market leading products and transparent supply contracts. We’re proud to stand as a top 3 C&I supplier that has achieved our growth organically, we have attracted and retained every single customer by focusing on what truly matters: a customer first approach, product innovation and the know-how to navigate market complexities. 

To grow our C&I business to such a level without inheritance or acquisition, we’ve steadfastly focused on our customer needs and what they tell is most important. Here are a few reasons why our customers trust us as a reliable supplier for the future, as they navigate their business through the energy transition.

1. Our customer first approach

2. Stability and financial backing

In a volatile energy landscape, stability is paramount. As a wholly owned subsidiary of the Marubeni Corporation, a Fortune Global 500 company (ranked 298, with over $50.96 billion revenue in FY24), we offer  robust financial backing and security. This means our customers have complete confidence in us as a secure, long-term partner, bringing much-needed reliability to their renewable energy supply.

3. A leader in renewable energy

Over the years, we’ve consistently been at the forefront of empowering the net zero transition, leveraging our extensive market expertise to create innovative solutions for businesses. This includes pioneering the UK's first independently certified renewable supply product and more recently our leading Traceable Renewable Supply product, which empowers customers with REGO reporting at half-hourly granularity. 

Our expertise also extends to Corporate Power Purchase Agreements (CPPAs), enabling businesses to forge long-term partnerships with renewable generation sites. These partnerships are crucial for expanding new renewable projects on the UK grid and fostering additionality in the net zero journey. Adding to this, we also offer a range of renewable supply products, including certified Standard and Natural Renewable Supply for reliable zero Scope 2 emissions reporting, and a Specific Renewable product tailored to source power from particular technologies or locations. It's this focus on pioneering solutions, led by deep market expertise, that consistently places us at the forefront of the renewable energy transition.

As we celebrate our 25th anniversary, becoming the 3rd largest C&I supplier is more than just a number; it’s a powerful affirmation of our founding vision and the trust our customers place in us. 

We know businesses today face ever-evolving energy market complexities on their pathway to net zero. That’s why our organic growth, built on customer-focused innovation, unwavering financial stability and our leadership in renewable energy means we’re well-positioned to stand by them. We’re here to help you navigate these challenges with confidence and achieve your energy goals, both now and well into the future.
