CityFibre believes interest in an alternative to BT Openreach is widespread across the UK.
According to the company's latest trading statement, turnover rose by 67 per cent during 2015 and hit £6.4 million. Meanwhile, gross profit went up by 68 per cent to £5.5 million.
Greg Mensch, Chief Executive of CityFibre, has hailed this upturn, as the year saw it "fully deliver on its organic growth strategy" and make the "truly transformational" acquisition of KCOM.
"So far in 2016, we've demonstrated rapid commercialisation of the acquired assets, which further underlines the strong demand for an alternative to BT Openreach at a national level."
Other highlights for CityFibre throughout the year included its entry into three new markets - Newport, Edinburgh and Glasgow - while the addition of the former KCOM assets to its portfolio means it now has a "significant presence" in 37 UK cities.
Mr Mensch added that its wholesale model has now been opened up to 24 of the top 30 cities outside London.
