British telecoms firm BT has revealed plans to invest £50m in the next three years to improve its broadband coverage to more UK cities.

The latest investment in the commercial fibre broadband programme will add fibre to more than 30 cities, offering the high speed broadband to over 400,000 additional locations.

As part of the programme, the latest investment would be aimed at deploying fibre to cabinets serving multi-dwelling units including apartment blocks; deploying additional fibre technology to build sites in urban areas and offer fibre connections to isolated areas with no fibre connections.

BT’s infrastructure unit Openreach Network Investment MD Mike Galvin said the fibre programme is going well by connecting homes and businesses across the UK.

"Some city areas have proved challenging in the past but we are returning to those and will pass hundreds of thousands of additional premises with fibre," Galvin 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.

"The UK is already ahead of its main European rivals when it comes to fibre, and is set to race ahead thanks to the BDUK plans that are already in progress across the country."

According to a new report, about five million UK premises already deploy fibre broadband across all networks putting it ahead of France, Germany, Italy and Spain and is also claimed to seal the gap on dominating nations including Japan and the US.

Recently, BT and French global telecommunications firm Alcatel-Lucent achieved the ‘fastest ever’ broadband speeds during a test and claim to achieve speeds of about 1.4 terabits per second.
