BT has identified the next 114 locations set to benefit from a fibre broadband upgrade.
The telecoms provider is currently spending £2.5 billion upgrading its internet infrastructure to deliver super-fast broadband speeds.
BT has been steadily rolling out fibre services across the UK's urban landscape, enabling households and businesses to sign up for its 40Mb Infinity broadband deals.
The firm has set itself a target of covering two-thirds of the UK with fibre broadband services by 2015.
Among the areas to be included in the latest round of upgrades will be Gillingham, Bognor Regis, Carlisle, Maidstone, Southport and Sunderland.
Together, the 114 exchanges serve more than one million homes and businesses, meaning BT and its wholesale partners could see a surge in the adoption of high-speed broadband deals.
Mike Galvin, Managing Director for Next-Generation Access at BT Openreach, commented that the firm's fibre broadband rollout is "the fastest in the world".
"We are on track to pass ten million homes and businesses next year before pushing on further," he said.
"Fibre broadband will transform peoples' experience of the internet and so I am sure the residents and businesses in these areas will welcome the news. No other company is doing as much as Openreach to bring super-fast broadband to the UK."
Virgin Media may dispute this claim – the broadband provider is also rolling out fibre broadband services across its UK network.
As of August 2011, the cable specialist had passed six million homes – encompassing a quarter of the population – with its 100Mb-capable fibre network.
But despite the efforts of BT and Virgin Media, the government has raised concerns about the rate at which high-speed broadband is being deployed nationwide.
Culture Secretary Jeremy Hunt warned this week that the UK is falling behind its European neighbours, particularly where rural broadband services are concerned.
He urged broadband providers to work together more effectively with the government to achieve the nation's shared digital goals.
