BT lost more than 200,000 broadband customers in the last three months of 2025 and profits fell sharply, mainly linked to its shared ownership of the pay TV broadcaster TNT Sports.
The telecoms company said that in the third quarter of its financial year, 210,000 customers left Openreach, its wholesale broadband network, and that it expected to lose a total of 850,000 broadband customers in its full financial year. That was down from previous guidance of 900,000.
