UK Power Networks, which delivers electricity across the East of England, London and the South East, has been named for the second year running in the Sunday Times Top 25 Best Big Companies to Work For listing.

The Ipswich-based company is in 25th place, with the rankings being based on detailed employee surveys covering a comprehensive range of work issues, including senior management, pay and benefits, development opportunities and the working environment.

Chris Degg, director of HR at UK Power Networks, said: “We are delighted that our colleagues have once again rated us among some of Britain’s best big companies to work for, based on the results of a confidential survey.

“When staff feel positive about their job and their employer, they are much more likely to go out of their way to provide a better customer experience. We will carefully study the survey results to understand what our employees are telling us, how we can respond positively to their feedback and continually improve our business.”

UK Power Networks also won the Utility of the Year title at the end of 2015 (a title it previous won in 2012) for reducing the number and duration of power interruptions, improving information and practical help given to customers, as well as developing pioneering innovations to deliver low carbon, affordable, secure electricity supplies.

The Sunday Times Top 25 list covers companies employing more than 5,000 employees and UK Power Networks ranks among household names such as McDonalds, Halfords, EE, Marriott and Iceland.

The top five firms in the list are Inchcape UK, Sytner Group, Nationwide Building Society, Bourne Leisure and American Express.
