About SEFE Energy

Gazprom rebranded to SEFE Energy in 2022.

SEFE Energy is a non-domestic energy supplier founded in the North West of England, the company initially started as Pennine Gas and later transformed into Gazprom Energy before evolving into SEFE Energy.

The company has grown substantially over the past 17 years, from a small group of employees serving under 100 customers to providing energy solutions to over 50,000 organizations in Britain, France and the Netherlands. SEFE Energy’s success is largely attributed to its commitment to excellent customer service, strong relationships, and a passion for growth.

SEFE Energy is a part of the SEFE Group, led by SEFE Securing Energy for Europe GmbH in Berlin, with a workforce of approximately 1,500 employees. The parent company, SEFE Marketing and Trading Limited, ensures that SEFE Energy always stays true to its original ethos of offering some of the most competitive fixed and flexible gas and electricity contracts on the market.

Despite the evolution of the company’s name, SEFE Energy remains committed to constant improvement of their service to ensure that both new and existing customers always pay a fair price for their energy.
