CityFibre has begun work to connect more than 57,000 homes and businesses across areas of East and West Sussex to full fibre broadband as part of a £108m Project Gigabit award.
Brsk has begun connecting customers in Stourbridge to its £15m fibre network build.
At least 100k homes and businesses in the region will be able to upgrade to full fibre once the rollout is complete.
Work in Brierley Hill and Kingswinford is well underway, with Cradley Heath and Selly Oak next in line to receive services from Brsk.
