Openreach has revealed it has managed to bring down the cost of delivering full-fibre infrastructure by half.
According to Matthew Hemmings, the body has been utilising new techniques to make deploying the technology more affordable.
This, he said, has helped to bring about successes such as the delivery of a fibre-to-the-premises network to 230 houses on the Brackenleigh estate near Carlisle.
"We're investing heavily in ultrafast broadband because we're committed to giving Britain a first-class network, capable of delivering the very latest communication services for households and business," Mr Hemmings commented.
He added that he is delighted to see customers in Brackenleigh already benefiting from this initiative, as some have "struggled with lower-than-average speeds in the past".
This comes after the government launched six pilots of full-fibre networks capable of offering broadband speeds of 1Gbps.
About £10 million is being spent on innovative ways of boosting connectivity in Aberdeen and Aberdeenshire, West Sussex, Coventry and Warwickshire, Bristol and Bath & North East Somerset, West Yorkshire and Greater Manchester.
