Gigaclear is looking to increase the number of homes served by its ultrafast network five-fold over the next 18 months.
The provider currently reaches 20,000 homes but wants this figure to hit 100,000 by the end of 2017.
This increase will be driven partly by a £10 million cash injection from Broadband Delivery UK (BDUK), as well as its own funds.
Matthew Hare, Chief Executive of Gigaclear, believes its fibre-optic cables represent an upgrade on what is being offered by rival providers such as BT.
"BT’s copper, the cables and the ducts, just aren’t working,” he told the Telegraph.
"We’re building fibre from scratch, and the proof is that not one customer cancelled last month."
Mr Hare added that BT "wants to sweat its existing copper-based assets" for as long as possible, which he believes will drive up maintenance costs in the long run.
