UK wholesale fibre network infrastructure provider CityFibre has revealed a 2.5 billion pounds ($3.2 billion) investment plan that it expects to boost connectivity across the UK.

Under the plan, 37 towns and cities that already have critical fibre spine assets will have their infrastructure expanded, with the expectations that roughly five million homes connected to full fibre, in line with the government’s idea of having 15 million homes connected by 2025.

CityFibre’s fibre-to-the-home builds are currently underway in Milton Keynes, Peterborough and Aberdeen. Construction is also due to start in Edinburgh, Stirling, Coventry and Huddersfield before the end of this year and Cambridge, Leeds and Southend-on-Sea early next year.

The company said that with a head-start in 37 towns and cities, this full fibre investment plan enables it to further accelerate its rollout, catalyzing huge economic growth in regional towns and cities across the country and transforming the UK’s digital future.
