BT Openreach CEO Liv Garfield will leave the company in the spring next year to become CEO at water company Severn Trent.
Garfield joined BT Openreach in April 2011 and has worked for BT Group for 11 years.
In her role at BT Openreach, she led the company’s £2.5bn roll-out of fibre broadband.
There are now two million subscribers to the company's superfast fibre compared to 100,000 in April 2011. “Our commercial programme to bring fibre broadband to two thirds of UK premises is almost complete, while BT’s public sector broadband partnerships are making good progress,” said Garfield.
BT said her successor will be announced in due course.
Only last week Garfield led a presentation about how super-fast broadband is changing the lives of people and businesses in rural areas. The company’s flagship rural broadband project in Cornwall has now connected 82% of premises and it aims to connect 95 by the end of 2014.
More than 35,000 homes and around 4,130 small businesses are now making use of the superfast connection.
The project, which is funded by the EU, Cornwall Council and BT now has connections to 200,000 premises in Cornwall. Currently, about 18% of these have taken up the broadband that offers speeds between 24Mbps and 330Mbps. Cornwall wants 30% of its connections to the premises to be fibre, compared to the UK average of 0.3%.
