Who are E.ON?

E.ON are one of the 'big six' energy suppliers in the UK. Formally known as Powergen, the company was created in 1990 and was subsequently bought by German energy giant E.ON in 2002. It assumed the name of its parent company in late 2007.

The supplier has won uSwitch's Large Supplier of the Year two years in a row.


E.ON customer satisfaction

Not only did E.ON win Large Supplier of the Year in the uSwitch Energy Awards 2017, the supplier increased its score from last year by 4%.

E.ON also came first in the incentives and rewards category.

David Bird, Managing Director Residential at E.ON UK said of the news:

"We’re delighted to have been voted best of the larger suppliers for customer satisfaction for the fifth year running. This success is testament to all our colleagues who have helped us provide a high level of service which is valued by our customers. I’m very proud that E.ON has continued to make significant improvements, this year not only increasing our score for overall satisfaction, but also increasing our rankings for both meter reading and energy efficiency. Our customers are our number one priority, which is why we remain committed to offering excellent service, competitive products and energy solutions that will help them save energy and pay less, making improvements that really matter to them."

The customer service rating is based on an independent YouGov survey that was conducted between 27th October and 1st November 2016. A total of 5,028 UK energy consumers were asked their opinions on a wide range of issues relating to satisfaction with their energy suppliers. The figures have been weighted and are representative of all UK adults (18+).
