BT will be throwing a hefty £50 million at fibre broadband expansion. This will bring greater connectivity to more than 30 cities and over 400,000 properties, it has announced.

BT's fibre broadband offers speeds of up to 300Mbps with the likes of BT Infinity. BT says this is 50 times faster than the UK average. But that should change as BT rolls out more fibre connectivity across the country.

The UK is currently 73 per cent covered with fibre broadband. Through the Broadband Delivery UK programme, which is funded by the government, the plan is to cover 90 per cent of the UK in fibre broadband by 2015 or early 2016.

Mike Galvin, MD of network investment at Openreach, said: "We are reaching vast swathes of rural Britain with our public sector partners but we will upgrade these city areas under our own steam. Businesses in cities already have access to ultra-fast speeds but fibre will give them greater choice."

BT aims to bring fibre to cities that were missed before, because of technical challenges, to apartment blocks, and laying "fibre-to the premises" technology for new builds.

BT Infinity fibre optic broadband pricing currently starts at £7.50 a month.
