So Energy has signed a three-year deal for the UK arm of the Swiss utility Axpo to become the sole buyer of energy on the wholesale gas and power markets for its nearly 200,000 customers.
The supplier said the partnership would allow it to provide more renewable energy to its customers, whilst continuing to offer competitive tariffs.
Simon Oscroft, co-founder of So Energy, said: “We’re delighted to sign this energy trading deal with Axpo, the biggest since we were founded five years ago. We’ve grown rapidly since then, quadrupling in size in the last 18 months, and now supply great value green energy to almost 200,000 customers.
“This deal means we can buy the best value energy in advance for our customers’ contracts, meaning we can continue to grow at existing rates and continue to provide market leading customer service and tariffs into 2020 and beyond.”
Axpo head of UK origination, Steven McCarthy, said: “Axpo is recognised as being reliable, sustainable and innovative. So Energy are a fresh and innovative supplier in the UK with ambitions to grow sustainably.
“This deal will provide So Energy with the means to manage the wholesale risks associated with the business growth and represents an important milestone for Axpo UK in expanding our business activities.”
Last month, Yu Group signed an exclusive wholesale trading agreement with Smartest Energy.
