Kirby has previously served as president and CEO of Swedish telecoms provider Telia, with experience at Virgin Media and Denmark's TDC.
She has been a member of the BT Group board for the past four years.
His legacy includes BT's push to build a national fibre network, offering discounted wholesale fibre pricing to major broadband providers in exchange for shifting customers to the grid.
U.K. telecoms regulator Ofcom in May ruled that BT subsidiary Openreach's Equinox 2 wholesale pricing scheme was allowed.
"Based on the evidence available to us, we don't consider Openreach's new pricing discounts to be anti-competitive," Ofcom said at the time.
