Eon and Npower’s business energy supply units are to merge.
Npower’s business supply unit was originally left out of the deal which saw its domestic retail division being rolled into Eon after the German parent companies did an asset swap.
However, Eon said it now makes sense to bring everything under one roof.
“Bringing together our two successful Industrial & Commercial units into a single organisation creates one of the largest B2B energy businesses in the UK,” said CEO Mike Lewis.
“These are fundamentally two complementary companies that bring together wider expertise in different areas of the market. What this means for British business is an expansion of our abilities to offer a greater range of smarter and personalised support to help meet their business efficiency and zero carbon ambitions.
“This is the latest stage of a process to build a more sustainable business and to succeed in this extremely challenging market.”
Eon is hoping to integrate the two businesses, including migrating them to a single IT system, by the end of next year.
It is not yet clear how many roles may be at risk due to duplication.
