BT has announced it has one million web users signed up to its wholesale broadband connect (WBC) service.
The body's Wholesale division has been rolling out the high-speed technology, which is based on 21st Century Network and ADSL2+ technology, across the UK for the past few months.
People with access to the WBC service will be able to enjoy speeds of up to 24Mb.
Sian Baldwin, BT Wholesale's Director of Broadband and Content Services, said there had been "unprecedented demand" for the technology since the start of the year.
She added: "We are extending our coverage and delivering even greater availability as a priority so that we have enabled exchanges serving 20 million UK homes and business by spring 2011."
BT recently confirmed that around 100,000 homes and businesses in London are benefitting from its £1.5 million investment in fibre optic broadband services.
Residents in Canonbury, Edmonton and Enfield are among those with access to the technology.
