The network has been built to make available gigabit-capable connectivity to the villages of North Somercotes, near Louth and Donington, to the north of Spalding.
Elsewhere, the majority of the build in Alford is also now complete with the last remaining premises expected to be passed and ready to connect shortly.
Julian Chalk, Quickline’s Head of Enablement and Engagement said:“Fast and reliable full fibre broadband is a necessity in everyday modern life and we are delighted that we have made it available to a further 4,000 premises in rural Lincolnshire.
“Our rollout is ongoing and more rural, hard-to-reach communities will be lit up soon as we continue on our mission to provide decent connectivity to those places that have been left behind by other providers.”
