Plusnet chief executive Andy Baker has left the firm while almost all the telecoms firm’s Sheffield head office staff will be transferred to parent company BT.

In six years at the firm Baker doubled turnover to £410 million while the company’s workforce also doubled to almost 1,700 people in Sheffield and Leeds.

The streamlining will see all non-call centre workers move into the parent company from February 2020, with redundancies “very unlikely”.

“The time is right,” said Baker, whose role will become defunct. “I have had an amazing six years. But I didn’t want to outstay my welcome. This is about the next chapter in Plusnet’s evolution.

“Plusnet can’t continue to grow the way we have so far. We have got find a way to deliver a better model.

“No office closures are proposed as part of this move and investment in frontline services will continue to be treated as a priority in the coming months and years.”

Marc Allera will continue as CEO of BT’s consumer division, which includes Plusnet and EE.

He said: “After six fantastic years leading the great team at Plusnet, Andy has decided to take a new direction and I’d like to offer my sincere thanks for all the hard work he has done for Plusnet and its customers.

“Plusnet is one of the three brilliant brands in BT’s Consumer Division.”
