Network provider CityFibre has claimed that millions of UK broadband customers are being served by what is claimed to be " full - fibre " when , in fact , they are receiving services still heavily reliant on legacy copper cables . The problem has largely been blamed on a lack of transparency, especially when it comes to educating organisations on what fibre technology actually offers and its availability throughout the country. The company , which announced the claim after reviewing the satisfaction levels of 3,400 broadband customers , accused the Advertising Standards Authority of being " backwards - looking " and of failing to crack down on use of the term . While 65 % of respondents said they had upgraded to a " full - fibre service " , just 3 % of the UK actually has access to full fibre to premises .
