YouFibre has connected the 2,500th customer to its full fibre network, which is being built by infrastructure partner Netomnia.
CityFibre has kicked off a £30m full fibre network expansion project in Huddersfield.
CityFibre's presence in the city was first felt in 2014 when it launched an independent 52km fibre network providing full fibre connectivity to 176 public sector sites and the town's business population.
The new project, delivered in partnership with Vodafone, also involves Brighouse-based contractor SDH Project Services which has been appointed to deliver the programme on CityFibre's behalf. The project is due to be completed by 2021.
Steve Moore, CityFibre's City Development Manager for Huddersfield, said: "Huddersfield has so much to gain from fresh investment in its broadband infrastructure. For instance, recent research estimates that over the next 15 years, the roll-out of full fibre could unlock £18m in business productivity and innovation, and £11m from new start-up activity.
"Digital investment has the ability to transform businesses and communities. In the year ahead, we want to work with as many organisations as possible to raise awareness of our plans for the town and ensure everyone understands the long-term importance of reliable, ultrafast speed and limitless capacity broadband."
Through its partnership with Vodafone, CityFibre's objective is to bring next generation full fibre infrastructure to five million UK homes and businesses by 2025, representing a third of the UK Government's target of 15m homes by 2025.
