David Cameron has turned on Gigaclear's 1Gb fibre-to-the-premises broadband network in the Parish of Northmoor, Oxfordshire.
Homes and businesses can now gain access to ultra-fast download speeds, courtesy of fibre-optic cables delivered straight to their premises.
The project was financed by the Department for Environment, Food & Rural Affairs' £20 million Rural Community Broadband Fund, along with £186,000 matched funding from Gigaclear.
Prime Minister David Cameron said it was "great" to see the launch of super-fast broadband in Northmoor, Moreton and Bablockhythe.
"This is a great advertisement of how a small community can come together with the help of the government’s Rural Community Broadband Fund to get some of the fastest broadband in the country brought directly to their homes," he stated.
Mr Cameron urged everyone to take up the opportunity to access next-generation broadband.
Graham Shelton, Chair of the Parish Council, said the delivery of ultra-fast fibre broadband across the local community "catapults" it straight into the 21st century.
He praised West Oxfordshire District Council for its "unfailing support" during the grant application process.
"We also want to thank the Prime Minister for supporting us today on what is a truly momentous occasion for all of us here," Mr Shelton stated.
