TalkTalk's plans for fibre-to-the-premises (FTTP) broadband go beyond the localised network it is building with Sky and CityFibre in York.
The service provider is to launch full-fibre broadband services - offering ultra-fast download speeds - in the city, but it hopes to make FTTP more widely available in the UK.
Speaking to City AM, TalkTalk Chief Executive Dido Harding claimed the £10 million joint venture - which is geared at challenging the dominance of BT's fibre infrastructure - could be just the start.
She claimed TalkTalk is "deadly serious" about developing its own next-generation, full-fibre infrastructure, entirely separate from BT's wholesale network.
"In a year’s time we’ll have built out the network, done a significant amount of marketing and have a pretty good sense of whether [the economics work]," Ms Harding told the news provider.
She said the more TalkTalk looks at the FTTP rollout project, the more confident the company becomes.
"We think you can roll the network out to 10 million households across the UK over five to ten years," Ms Harding stated.
