Britain’s biggest broadband company, BT has pledged to spend six billion pounds (7.6 billion euros) on superfast fibre-optic cabling and 4G mobile in the next three years.
The follows criticism from its rivals and concerns expressed by the UK telecom regulator Ofcom.
BT, which is the UK’s former telecommunications monopoly, runs the profitable networks division Openreach which provides the lines used by its competitors, including Sky and TalkTalk .
They have accused BT of not investing enough in the network and providing a poor quality of service and had pushed for Openreach to be separated from the rest of the company.
BT said it would improve customer service and increase the supply of ultrafast broadband to a minimum of 10 million homes and businesses in the next three years, with an ambition to reach 12 million.
Two million properties will have fibre connected to the premises, it said, one of the improvements at the top of the regulator’s wish list because it can provide ever faster speeds.
At the same time BT reported a better-than-expected six percent rise in full-year earnings causing its shares to rise.
