About Us | The Full Fibre Broadband Network


We founded CityFibre in 2011 to set a new standard in our industry, bring much-needed choice to the market and unlock the digital potential of entire communities across the UK.

​​We’re doing this by purpose-building a network fit for the data age, one that enables connections so quick and reliable they can be taken for granted. ​

​With its near-limitless capacity, easy upgradability and state-of-the-art fibre exchanges, our intelligent network is completely independent and designed to surpass expectations. ​

​Today we’re the UK’s largest open access, fibre only operator, with services live in cities, towns and villages across the country. But it’s our investment in quality and our commitment to getting it right first time for people and planet that’s making us the network of choice for many residential, business, mobile and public sector sites nationwide.
