BT Openreach has fully launched its up to 330Mb Fibre-to-the-Premises (FTTP) broadband service - the fastest available in the UK.
The products - which have only previously been available to communication providers on an early market deployment basis - will initially be available within the 15 exchange areas where FTTP infrastructure has been deployed.
However, availability will improve as BT Openreach expands the FTTP network to other exchange areas.
The firm is set to explore the option of deploying the service to new housing developments and multi-dwelling units such as apartment blocks.
And from spring 2013, BT also plans to make FTTP available 'on-demand' in areas covered by its Fibre-to-the-Cabinet (FTTC) network.
The firm has passed ten million premises with the technology to date and is due to pass approximately two-thirds of UK premises by the end of 2014.
Mike Galvin, Openreach Managing Director for Network Investment, said the commercial launch of FTTP is "a major milestone".
"Whilst we believe that FTTC will provide speeds that are suitable for consumers for some time, these FTTP products will allow communication providers to offer small enterprises and other bandwidth-hungry users the option of even higher speeds – some of the fastest in the world – and build propositions which help to grow the market for these higher-speed services," he stated.
BT is investing £2.5 billion upgrading its national telecoms infrastructures to support super- and ultra-fast broadband services.
The firm aims to deliver super-fast broadband services to two-thirds of the UK by the end of 2014.
