CityFibre has criticised Ofcom for focus too heavily on the restructuring of BT's infrastructure division Openreach.
According to Greg Mesch, Chief Executive of the internet service provider, the issue is proving to be a distraction from other issues in the broadband sector, the Financial Times reports.
As a result, he believes the concentration on BT is "misguided" and that more needs to be done to "provide a level playing field for other companies".
"The UK’s digital infrastructure is too important to be left solely to BT or Openreach [even if they are forced to separate]," Mr Mesch commented.
CityFibre has already set itself a target of establishing a presence in 50 towns and cities across the UK by 2020.
This means its fibre-to-the-premises deployments would be available to a potential customer base of five million homes.
However, Mr Mesch suggested earlier this year that the outcome of Ofcom's Strategic Review of the digital communications market could enable the company to go even further.
Speaking to V3, he said: "With the Ofcom review forcing BT to give us rights to its infrastructure, I can jump from 50 to maybe 100 cities and take the customers I have now and grow the footprint to ensure we have the scale they want."
This, he stated, could lead to CityFibre establishing itself as a "full blown competitor" to BT Openreach.
The company recently reported that its turnover rose by 67 per cent during 2015 and hit £6.4 million, while gross profit went up by 68 per cent to £5.5 million.
Mr Mesch said the positive trading data "further underlines the strong demand for an alternative to BT Openreach at a national level".
