Quickline has expanded its Lincolnshire network to the communities of Ancaster, Wilsford and Colsterworth, situated close to Grantham.
Lit Fibre will launch its full fibre network into Warminster and the surrounding areas in early 2023.
Installation is underway and once live, thousands of homes throughout Warminster will have access to fibre.
Lit Fibre is also supplying full fibre broadband to Chippenham and Melksham with further towns in Wiltshire to be announced soon.
CEO Tom Williams said: “We want to be at the heart of the Warminster community by bringing our full fibre internet right to customers' front doors, bypassing the old, unreliable copper infrastructure that’s being used currently.”
