CityFibre has begun work to connect more than 45,000 homes and businesses across areas of Leicestershire and Warwickshire to full fibre thanks to an award of £77m as part of Project Gigabit.
Lightning Fibre has connected its first Worthing customer, after recently expanding into West Sussex.
The independent company, founded 2018, covers East Sussex and Kent using both its own full fibre infrastructure and third party networks.
As a symmetric network, Lightning Fibre broadband delivers upload and download speeds of 150Mbps or more at the modem, along with fixed prices and rolling contracts.
It also helps customers reduce costs by not increasing prices each April.
