Vodafone has begun trialling its new broadband service capable of offering speeds of up to 1Gbps.
Some 50 homes in Milton Keynes are testing Vodafone Gigafast Broadband, which will subsequently be rolled out more widely across the area.
According to the provider, the new broadband service runs over fibre optic cables at every stage, rather than copper-based wires.
As a result, it believes customers will enjoy a faster and more reliable service, with every member of the family able to go online simultaneously across multiple devices.
Nick Jeffery, Chief Executive of Vodafone UK, commented: "Full-fibre is vital to our digital economy and to the UK's future as a digital leader, yet just three per cent of UK premises currently have access to it."
This, he said, is why the company plans to make Vodafone Gigafast Broadband available on a mass scale, with a view to reaching one million homes by 2021.
The trial forms part of a wider long-term strategic partnership between Vodafone and CityFibre, which they believe will help to "bridge Britain's fibre gap".
