BT is planning to launch fibre-to-the-premises (FTTP) services offering download speeds of up to 300Mb.
The new BT Infinity 300 service will give businesses and households in full-fibre enabled areas the opportunity to increase their broadband speeds.
Access to the new 300Mb deals will initially be limited, with BT having deployed FTTP infrastructure within just 50 exchange areas to date.
Subscribers will be able to take advantage of up to 20Mb upload speeds when the FTTP service launches. It will offer unlimited downloads, and be free of traffic shaping.
Existing FTTP customers will be able to upgrade to the faster download and upload speeds by upgrading to the £50 per month Unlimited package.
At present, around 100,000 UK premises are able to sign up for FTTP broadband with BT. This is where fibre connections are used between the local exchange and the user's computer.
BT is continuing to extend its fibre footprint, although the majority of super-fast broadband subscribers are currently reliant upon a fibre-to-the-cabinet (FTTC) connection.
The firm has also launched FTTP on-demand, which gives businesses the opportunity to pay for an upgrade from FTTC broadband.
Users can request that BT adds a fibre connection between their premises and the nearest street cabinet, allowing them to take advantage of up to 300Mb download speeds.
The company says the BT Infinity 300 service will launch later in 2013.
