About us

We began our journey as an ambitious, independent gas supplier in the Northwest of England, built on great relationships and a passion for growth and excellent customer service. We continuously developed our products to reach more customers and in less than ten years, we grew from employing a handful of people and suppling less than a hundred customers to become one of Britain’s leading non-domestic energy suppliers. We now supply thousands of businesses and organisations with the energy they need to provide their products and services used by millions of people across Britain, France and the Netherlands. We are part of the SEFE Group – led by SEFE Securing Energy for Europe GmbH in Berlin – which employs approximately 1,500 employees and together, our mission is clear.

The energy & commodities world has been changing for over a decade driven by forces of decarbonisation, competition, digitalisation and shifting customer expectations. Our strategy equips us to expertly seize these opportunities as the energy transition gathers even greater pace. We have a number of key transformation projects to evolve us even further to meet the market & client demands of the next decades: as we evolve our portfolio mgmt. capabilities, expand our Continental European footprint and deliver our transformational data architecture suite we are confident of our metamorphosis.

We’re strengthening our foundations – placing data and technology even further at the heart of our business model. We are friendly, enthusiastic, and purposeful and encourage everyone to have a learning mindset, challenge respectfully, have a bias for action and to make evidence-based decisions. You can expect to receive a valuable mix of challenge and support for your role, your wellbeing and ambitions. We are a place where you can be yourself and since 2012, we have been accredited with the Investors in People Gold standard and Ecovardis Silver accreditation this year.
