BT has revealed it has now passed more than 25 million premises with its fibre broadband network.
This, it said, works out to around 85 per cent of the UK, which means 90 per cent of the country can now get fibre broadband speeds from all networks.
BT also stated that it is on track to bring fibre to 95 per cent of the UK by the end of 2017 and is looking at going further.
The provider is currently trialling G.fast technology that offers speeds of up to 330Mbps in three locations and will commence two further trials over the next year.
BT is also looking at rolling out Fibre-to-the-Premises and XG-FAST technology, which it said means it has a "wide range of technologies" that can help the UK "maintain its position as a leading digital economy".
Openreach secured 415,000 fibre broadband net additions during the first quarter of 2015, with other service providers connecting 48 per cent of these. BT said this demonstrates the "consistent market-wide demand for fibre" across the country.
The company went on to confirm that in the three months to March 31st 2016, it added 214,000 retail fibre broadband customers, including those from EE, taking its fibre broadband customer base up to 4.1 million.
This means that nearly half of BT's retail broadband customers now use fibre.
Gavin Patterson, Chief Executive of the company, commented: "Customers want to be online wherever they are and we will be there for them.
"Our multi-billion pound investment plans will see both fibre and 4G reach 95 per cent of the UK and we won't stop there. The UK is a digital leader and our investment in ultrafast broadband will help it stay ahead."
